classes/controllers/FrmStylesController.php (2)
806-821: LGTM — Backward-compatible API extension.The
extra_argsparameter with defaults maintains backward compatibility while enabling flexible customization of the CSS editor. The PHPMD warnings about unused variables are false positives — these variables ($show_errors,$custom_css,$heading,$textarea_params) are used in the includedcustom_css.phptemplate.Note: The
$messageparameter appears genuinely unused in this method. Consider either using it or removing it from the signature if it's not needed.
878-887: Consider escaping the$idin the inline JavaScript.While
$idis currently developer-controlled (defaulting to'frm_codemirror_box'), usingesc_js()would be a defensive practice for the JavaScript context:wp_add_inline_script( 'code-editor', sprintf( 'jQuery( function() { window.%s_wp_editor = wp.codeEditor.initialize( \'%s\', %s ); } );', - $id, - $id, + esc_js( $id ), + esc_js( $id ), wp_json_encode( $settings ) ) );This protects against potential XSS if
$idever originates from user input in future refactors.js/src/admin/styles.js (1)
38-53: Consider using the retryInterval from cssEditorOptions.Line 47 hardcodes the retry interval as
500in thesetTimeoutcall, butthis.cssEditorOptions.retryIntervalis already defined with the same value. Using the property would make the retry interval configurable in one place.Apply this diff:
setTimeout( () => { this.cssEditorOptions.retryCount++; this.initCustomCSSEditorInstance(); - }, 500 ); + }, this.cssEditorOptions.retryInterval );

js/frm_testing_mode.js (1)
1-2: Minified bundled file should not be manually reviewed; verify the build process.This file appears to be a minified/bundled JavaScript output, not source code. The static analysis warnings (switch fallthrough, label/variable conflicts, function reassignments) are expected artifacts of minification and not indicative of actual defects.
Key concerns:
- Manual review is impractical: Minified code is compressed and unreadable, making line-by-line review error-prone and ineffective.
- Build artifacts should not be versioned: Bundled/minified files are typically generated during the build process and should not be committed to the repository.
Recommendations:
- Verify whether a source file (e.g.,
js/src/frm_testing_mode.js, as suggested by the relevant code snippets) exists. If so, include the source in the PR diff for review instead.- Exclude bundled/minified files from version control using
.gitignoreand regenerate them as part of the build pipeline.- Ensure the build process is documented and automated so minified outputs are consistent and reproducible.
Please verify: (1) whether
js/src/frm_testing_mode.js(source) exists and should be included in this PR, (2) the role ofjs/frm_testing_mode.js(is it generated or manually maintained?), and (3) whether bundled files should be included in future PRs.js/addons-page.js (1)
1-1: Minified bundle cannot be meaningfully reviewed without source maps.These are bundled/minified assets generated by a build process. To properly review changes, please provide either:
- Source map references
- Unminified source code from
js/src/directory- Build configuration details
Per the AI summary, these changes appear to be formatting-only with no behavioral changes, but this cannot be verified from minified code alone.

1-2: Minified build artifact — no source-level review applicable.This is a bundled/minified output file. The static analysis warnings (switch fallthrough, throw in finally, use before declaration, function reassignment) are false positives generated by the bundler's transpilation of generators and async/await patterns. These are expected in minified Babel/Webpack output.
Ensure the source files in

83-84: LGTM — Helper instantiation is appropriate.Instantiating
FrmCssScopeHelperonce before the loop is efficient, avoiding repeated instantiation inside the foreach.
262-264: LGTM — Consistent with existingcustom_csshandling.CSS fields require special characters (
{,},;, etc.) that would otherwise be stripped. Excludingsingle_style_custom_cssfromstrip_invalid_charactersis correct and consistent with howcustom_cssis already handled.
756-758: LGTM — Sensible defaults for the new settings.The opt-in pattern (
enable_style_custom_cssdefaulting tofalse) and empty string for CSS content are appropriate defaults.js/formidable_blocks.js (1)

classes/helpers/FrmCssScopeHelper.php (4)
1-6: LGTM — Well-structured CSS scope helper.The class provides clean, focused functionality for CSS scoping with
nest()andunnest()operations. Good separation of concerns.
16-89: Well-implemented CSS nesting with proper edge case handling.The implementation correctly:
- Strips comments before processing
- Handles
@keyframeswithout nesting (as keyframe percentages aren't selectors)- Recursively processes nested at-rules like
@media- Handles comma-separated selectors
One consideration: if the input CSS is malformed (e.g., unclosed braces),
find_matching_brace()returns$length - 1, which may produce unexpected output. However, for user-provided CSS, this graceful degradation is acceptable.
99-173: LGTM — Correctly reverses the nesting operation.The
unnest()method properly handles:
- Selectors that have the prefix (removes it)
- Selectors without the prefix (preserves them unchanged)
- Recursive processing for nested at-rules
216-252: Robust brace matching with string-awareness.Good implementation that correctly handles:
- Nested braces (level tracking)
- String literals (avoids false positives from braces in
content: "{")- Escaped quotes within strings
classes/controllers/FrmStylesController.php (1)
831-835: LGTM — Clean extension for per-style custom CSS.The logic correctly checks both the enable flag and content presence before returning the single style's custom CSS, falling through to the global CSS logic otherwise.
resources/scss/admin/components/settings/_misc-components.scss (1)
18-24: LGTM! CodeMirror styling is appropriate.The
!importantdeclarations are necessary here to override CodeMirror's default styles, and scoping to.frm-style-componentprevents unintended side effects elsewhere.js/admin/style.js (1)
1094-1107: LGTM! Reset function is well-guarded.The function properly checks for element existence before manipulation and integrates cleanly into the existing reset flow.
classes/views/styles/custom_css.php (3)
8-8: LGTM! Dynamic heading enables flexible messaging.Using a variable for the heading allows callers to customize the message, improving reusability.
12-14: LGTM! Strict comparison is appropriate.Using strict equality (
===) for the boolean check is a best practice in PHP.
16-20: The review comment is incorrect—$textarea_paramsis always initialized before use.The controller method
FrmStylesController::custom_css()(lines 17–20) initializes$textarea_paramswith a default value before including the view file. The conditional block in the view (lines 16–18) only optionally adds a'class'key to an array that is guaranteed to exist. No undefined variable warning will occur.// In controller (lines 17-20): $textarea_params = ! empty( $extra_args['textarea_params'] ) ? $extra_args['textarea_params'] : array( 'name' => 'frm_custom_css', 'id' => $id, ); // Then the view is included with $textarea_params already in scopeclasses/views/styles/_quick-settings.php (2)
229-249: LGTM! Toggle control is well-integrated.The Custom CSS toggle is properly wired with appropriate labels, ARIA attributes, and checked state handling.
274-285: LGTM! Style class display with copy functionality.The style class display shows the scoped class name with a copy icon, providing good UX for users who need to reference the class name.
js/src/admin/styles.js (3)
12-18: LGTM! Properties are well-defined.The new properties support the CSS editor instance management and retry logic appropriately.
163-176: LGTM! Clipboard API guards are robust.The function properly checks for clipboard API availability before attempting to use it and handles multiple copy labels correctly.
178-187: LGTM! Toggle visibility is straightforward.The function correctly toggles the editor visibility based on the checkbox state with proper guards for element existence.

js/admin/style.js (1)
1094-1107: Optional: also clear editor value when resetting the custom CSS UI
resetCustomCSSEditor()safely unchecks the toggle and hides the editor wrapper, which is great. If the reset operation is also meant to wipe any per‑style custom CSS, consider additionally clearing the underlying textarea/input value (or invoking whatever logic normally syncs editor content) so that stale CSS doesn’t reappear when the toggle is turned back on after a reset.

</function_calls>Based on my comprehensive analysis of the CSS file, I can now provide the rewritten review comment:
✓ No duplicate CSS properties or conflicting background values detected in the minified output.
After parsing and analyzing all 700+ CSS selector blocks in the minified file, no instances of duplicate properties (including
text-align,border-radius, ormin-widthwithin the same selector) or conflictingbackground-color+backgroundcombinations were found. The minified CSS is structurally sound.If Biome previously flagged these issues on an earlier version, they appear to have been resolved in the current state of the file. If you have specific Biome error output to validate, please share it for cross-verification.

858-891: Sanitize the$idparameter before using it in JavaScript generation.The
$idparameter is used directly in thesprintf()call at lines 882-884 to construct inline JavaScript without sanitization. If$idcontains quotes or special characters, this could lead to JavaScript injection.For example, if

831-848: Consider adding type validation for the$single_style_settingsparameter.The parameter name
$single_style_settingssuggests it might be an object (like the global$settingsaccessed at line 837), but the implementation uses array access at line 833. If a non-array value is passed, this will cause a fatal error.Consider one of these approaches:
Option 1: Add a type hint and update the parameter name for clarity:
-public static function get_custom_css( $single_style_settings = null ) { +public static function get_custom_css( $style_post_content = null ) { // If the single style settings are passed, return the custom CSS from the single style settings. - if ( ! empty( $single_style_settings['single_style_custom_css'] ) && ! empty( $single_style_settings['enable_style_custom_css'] ) ) { - return $single_style_settings['single_style_custom_css']; + if ( ! empty( $style_post_content['single_style_custom_css'] ) && ! empty( $style_post_content['enable_style_custom_css'] ) ) { + return $style_post_content['single_style_custom_css']; }Option 2: Add runtime type checking:
public static function get_custom_css( $single_style_settings = null ) { // If the single style settings are passed, return the custom CSS from the single style settings. - if ( ! empty( $single_style_settings['single_style_custom_css'] ) && ! empty( $single_style_settings['enable_style_custom_css'] ) ) { + if ( is_array( $single_style_settings ) && ! empty( $single_style_settings['single_style_custom_css'] ) && ! empty( $single_style_settings['enable_style_custom_css'] ) ) { return $single_style_settings['single_style_custom_css']; }

203-210: Fix JSDoc type and alignment issues.ESLint flags two issues:
{bool}is not a valid JSDoc type - use{boolean}instead- JSDoc block lines should be aligned
Apply this diff:
- /** - * Copy to clipboard if the Clipboard API is not available. - * - * @param {string} couponCode The string being copied to the clipboard. - * @param {HTMLElement} copyButton Used to position the temporary input element. - * @return {bool} - */ + /** + * Copy to clipboard if the Clipboard API is not available. + * + * @param {string} couponCode The string being copied to the clipboard. + * @param {HTMLElement} copyButton Used to position the temporary input element. + * @return {boolean} True if the copy was successful. + */
217-231: Apply styles before appending to avoid potential layout shift.The temporary input element is appended to the DOM before being positioned off-screen. While brief, this could cause a momentary layout shift. Apply positioning styles before appending.
Apply this diff:
const temp = document.createElement( 'input' ); temp.setAttribute( 'type', 'text' ); temp.value = couponCode; + + // Hide the input so it doesn't show up in the UI. + temp.style.position = 'absolute'; + temp.style.left = '-9999px'; + temp.style.top = '-9999px'; copyButton.parentElement.appendChild( temp ); temp.focus(); temp.select(); temp.setSelectionRange( 0, 99999 ); - - // Hide the input so it doesn't show up in the UI. - temp.style.position = 'absolute'; - temp.style.left = '-9999px'; - temp.style.top = '-9999px';classes/helpers/FrmCssScopeHelper.php (1)
216-252: Consider handling malformed CSS more defensively infind_matching_brace.When no matching closing brace is found, the method returns
$length - 1. This could lead to unexpected behavior with malformed CSS input (e.g., processing content beyond the intended block). Consider returningfalseor throwing an exception for unbalanced braces, and handling this case in the calling code.Example approach:
private function find_matching_brace( $css, $open_pos ) { $level = 1; $length = strlen( $css ); $in_string = false; $string_char = ''; for ( $i = $open_pos + 1; $i < $length; $i++ ) { // ... existing logic ... if ( '{' === $char ) { ++$level; } elseif ( '}' === $char ) { --$level; if ( 0 === $level ) { return $i; } } } - return $length - 1; + // No matching brace found - return false to signal malformed CSS + return false; }Then update callers to check for
falseand handle gracefully.

nest()method correctly:
- Preserves
@keyframescontent without nesting (which would break animations)- Handles multiple comma-separated selectors
- Recursively processes nested at-rules like
@media- Preserves declaration formatting
classes/controllers/FrmStylesController.php (2)
858-874: Logic for single-style custom CSS retrieval is correct.The method properly checks both
enable_style_custom_cssandsingle_style_custom_cssbefore returning single-style CSS, with appropriate fallback to global custom CSS. The static analysis warnings about unused variables are false positives—$show_errors,$custom_css,$heading, and$textarea_paramsare all used in the includedcustom_css.phpview file.
832-848: Good use of null coalescing for optional parameters.The implementation cleanly handles optional
extra_argswith sensible defaults using null coalescing operators. The conditional class addition forhide-if-jswhen CodeMirror is available is a nice progressive enhancement pattern.

889-918: Sanitize the$idparameter before embedding in JavaScript.The
$idparameter is embedded directly into JavaScript at lines 913-915 without sanitization. While current call sites use hardcoded safe values, the public method signature allows external callers to pass arbitrary values. For defense-in-depth:private static function enqueue_codemirror( $id = 'frm_codemirror_box', $placeholder = '' ) { + // Sanitize $id for safe use in JavaScript context + $id = preg_replace( '/[^a-zA-Z0-9_]/', '', $id ); + if ( ! function_exists( 'wp_enqueue_code_editor' ) ) {Alternatively, use
esc_js()when embedding in the sprintf call.js/src/admin/styles.js (2)
76-79: Optional chaining returnsundefined, notnull.Line 76 uses optional chaining (
?.dataset?.cssScope) which returnsundefinedif any property is missing, notnull. The check on line 77if ( null === cssScope )will not catch theundefinedcase, allowing line 80 to callCSS.escape(undefined)which returns the string"undefined".Apply this diff:
const cssScope = document.getElementById( 'frm_style_class_custom_css' )?.dataset?.cssScope; - if ( null === cssScope ) { + if ( ! cssScope ) { return; }
82-85: CSS injection mitigation is incomplete.While line 83 strips HTML tags, CSS injection attacks remain possible. Malicious CSS can use selectors,
background-image,@import,url(), orattr()to exfiltrate data or load external resources. Consider implementing a CSS parser/validator that whitelists safe properties and rejects dangerous constructs, or implement a strict Content-Security-Policy.Based on past review comment feedback, the HTML tag stripping added on line 83 only partially addresses the originally raised security concern.

17-90: Consider validating$class_nameparameter.The
$class_nameis directly concatenated at line 71 without validation. If an unexpected value is passed (e.g., containing special CSS characters or spaces), it could produce invalid CSS.Consider adding basic validation:
public function nest( $css, $class_name ) { + // Ensure class_name is a valid CSS identifier + $class_name = preg_replace( '/[^a-zA-Z0-9_-]/', '', $class_name ); + // Remove CSS comments but preserve newlines $css = preg_replace( '/\/\*.*?\*\//s', '', $css );
220-256: Fallback return value could mask malformed CSS errors.When no matching brace is found (malformed CSS), returning
$length - 1silently continues processing with potentially incorrect boundaries. This could produce garbled output without any indication of the problem.Consider logging a warning or returning a distinct error value:
- return $length - 1; + // Log malformed CSS for debugging. Return length to avoid further processing. + if ( defined( 'WP_DEBUG' ) && WP_DEBUG ) { + // phpcs:ignore WordPress.PHP.DevelopmentFunctions.error_log_error_log + error_log( 'FrmCssScopeHelper: Unbalanced braces in CSS' ); + } + return $length;js/src/admin/styles.js (1)
44-47: Use configured retry interval instead of hardcoded value.Line 47 hardcodes
500butthis.cssEditorOptions.retryIntervalis defined on line 16 for this purpose.Apply this diff:
setTimeout( () => { this.cssEditorOptions.retryCount++; this.initCustomCSSEditorInstance(); - }, 500 ); + }, this.cssEditorOptions.retryInterval );

1-16: LGTM on file structure and PHPDoc formatting.The ABSPATH security check and PHPDoc formatting with proper blank line separation before
@returntags look correct.
101-175: LGTM on unnest implementation.The unnest logic correctly mirrors the nest operation, properly handling the prefix removal while preserving selectors that don't have the prefix.
184-210: LGTM on formatting helper.The method correctly handles both single-line and multi-line CSS declarations with appropriate formatting.
classes/controllers/FrmStylesController.php (3)
833-848: Static analysis warnings are false positives.The PHPMD warnings about unused
$message,$show_errors,$custom_css, and$headingare false positives. These variables are intentionally created to be used by the view file included at line 848 (custom_css.php), which usesextractor direct variable access.
833-848: LGTM on thecustom_css()refactoring.The method now properly supports extra arguments with sensible defaults, maintaining backward compatibility while enabling the new single-style custom CSS feature. The conditional
hide-if-jsclass application for CodeMirror is appropriate.
860-877: LGTM onget_custom_css()enhancement.The conditional logic correctly checks both
enable_style_custom_cssandsingle_style_custom_cssbefore returning single-style CSS, falling back to global settings when not applicable.js/src/admin/styles.js (5)
12-21: LGTM - Clean initialization of CSS editor components.The new properties and configuration object are well-structured. The retry options with inline comments make the intent clear.
60-68: LGTM - Proper lazy initialization pattern.The method correctly implements caching and creates the style element only when needed.
167-185: LGTM - Robust clipboard implementation with fallback.The refactor to support multiple copy targets and the Clipboard API fallback properly addresses the previous review feedback. The implementation gracefully degrades when the API is unavailable.
192-201: LGTM - Clean visibility toggle implementation.Uses
getElementByIdas requested in previous feedback and implements a clean event-driven toggle pattern.
210-241: LGTM - Solid clipboard fallback implementation.The fallback correctly implements the pattern from previous review feedback, with proper error handling, cleanup, and off-screen positioning.

885-887: Sanitize/use safe construction for dynamic$idin inline JSThe
$idargument is passed straight into the inline JavaScript:sprintf( 'jQuery( function() { window.%s_wp_editor = wp.codeEditor.initialize( \'%s\', %s ); } );', $id, $id, wp_json_encode( $settings ) );This was already flagged previously; the risk is still present: if a caller ever passes an unsanitized or unexpected
$id, it can break the script (invalid identifier) and is a potential XSS vector in the JS context, even though the current core call sites are safe.A safer pattern is to use bracket notation on
windowand JSON‑encode both the DOM id and the window key:- if ( $settings ) { - wp_add_inline_script( - 'code-editor', - sprintf( - 'jQuery( function() { window.%s_wp_editor = wp.codeEditor.initialize( \'%s\', %s ); } );', - $id, - $id, - wp_json_encode( $settings ) - ) - ); - } + if ( $settings ) { + $editor_window_key = $id . '_wp_editor'; + + wp_add_inline_script( + 'code-editor', + sprintf( + 'jQuery( function() { window[%1$s] = wp.codeEditor.initialize( %2$s, %3$s ); } );', + wp_json_encode( $editor_window_key ), + wp_json_encode( (string) $id ), + wp_json_encode( $settings ) + ) + ); + }This keeps backward compatibility (
window.frm_codemirror_box_wp_editorstill exists) while making the JS generation robust against unexpected characters in$id.Also applies to: 890-890, 905-905, 914-916

829-847:custom_cssextra arguments look fine; PHPMD “unused” warnings are false positivesThe new
$extra_argshandling (dynamicid,placeholder,show_errors,custom_css,heading,textarea_params) is straightforward and keeps the textareaidaligned with the CodeMirror id/fallback. The local variables$message,$show_errors,$custom_css,$heading, and$textarea_paramsare intentionally used by the includedcustom_css.phpview via local scope, so PHPMD’s “unused” warnings here are not actually issues.If you want to future‑proof this a bit, consider also passing the
placeholderinto$textarea_paramsso the non‑JS textarea gets the same hint text when CodeMirror isn’t available.

851-867:custom_cssextra arguments wiring looks correct; static-analysis “unused” warnings can be ignoredThe new
$extra_argshandling (id,placeholder,show_errors,custom_css,heading,textarea_params) is wired consistently intoenqueue_codemirrorand the view via$textarea_params. The PHPMD warnings about$message,$show_errors,$custom_css,$heading, and$textarea_paramsbeing unused are false positives, since these variables are consumed in the includedcustom_css.phpview through PHP’s shared function-scope symbol table. No code change needed here.
878-895: Guard against array access onnullinget_custom_css(still unresolved)
$single_style_settingsdefaults tonull, but the function immediately accesses array offsets on it:if ( ! empty( $single_style_settings['single_style_custom_css'] ) && ! empty( $single_style_settings['enable_style_custom_css'] ) ) {Existing call sites still invoke
get_custom_css()without arguments, which will trigger “Trying to access array offset on value of type null” notices at runtime.Add an
is_arrayguard before dereferencing:- public static function get_custom_css( $single_style_settings = null ) { - // If the single style settings are passed, return the custom CSS from the single style settings. - if ( ! empty( $single_style_settings['single_style_custom_css'] ) && ! empty( $single_style_settings['enable_style_custom_css'] ) ) { - return $single_style_settings['single_style_custom_css']; - } + public static function get_custom_css( $single_style_settings = null ) { + // If the single style settings are passed, return the custom CSS from the single style settings. + if ( + is_array( $single_style_settings ) + && ! empty( $single_style_settings['single_style_custom_css'] ) + && ! empty( $single_style_settings['enable_style_custom_css'] ) + ) { + return $single_style_settings['single_style_custom_css']; + }The rest of the method can stay as-is.
909-942: Sanitize$idbefore embedding it into inline JavaScript for CodeMirror
enqueue_codemirror()now accepts a dynamic$idand uses it directly in the inline JS:sprintf( 'jQuery( function() { window.%s_wp_editor = wp.codeEditor.initialize( \'%s\', %s ); } );', $id, $id, wp_json_encode( $settings ) );Even though current call sites pass a hardcoded, safe ID and the method is admin-only, this is a JS injection footgun for any future/extensibility use where
$idmight be user-influenced.Recommend normalizing/escaping
$idbefore using it in JS (both the property name and the DOM ID). For example:- private static function enqueue_codemirror( $id = 'frm_codemirror_box', $placeholder = '' ) { + private static function enqueue_codemirror( $id = 'frm_codemirror_box', $placeholder = '' ) { + $id = preg_replace( '/[^A-Za-z0-9_\-]/', '_', (string) $id ); @@ - sprintf( - 'jQuery( function() { window.%s_wp_editor = wp.codeEditor.initialize( \'%s\', %s ); } );', - $id, - $id, - wp_json_encode( $settings ) - ) + sprintf( + 'jQuery( function() { window.%s_wp_editor = wp.codeEditor.initialize( \'%s\', %s ); } );', + $id, + $id, + wp_json_encode( $settings ) + )(or use appropriate WordPress escaping helpers if you prefer).
This keeps the API flexible while hardening against accidental JS injection via a malformed ID.
In modern WordPress plugin development, what are the recommended escaping or validation practices when embedding dynamic element IDs into inline JavaScript (e.g., for CodeMirror initialization), and does the core documentation endorse using functions like `esc_js()` / `sanitize_key()` for this purpose?

26-315: Comprehensive coverage for nesting/unnesting logic looks solidThe test suite exercises a wide range of selector types and at-rule scenarios (media, keyframes, supports, braces-in-strings, multiple selectors, combinators, etc.), which aligns well with the helper’s parsing behavior and should give good confidence against regressions.

229-249: LGTM! Toggle implementation is correct.The toggle uses proper field naming via
$frm_style->get_field_name()and correctly checksenable_style_custom_csswith! empty()for the checked state.
251-275: Implementation looks good. Previous issues have been addressed.The hardcoded class name issue from past reviews has been fixed—line 257 now dynamically constructs the class name using
'frm_style_' . $style->post_name. The null coalescing operator on line 254 properly handles missing values.

data-css-scopeattribute and label correctly display the dynamic style class name with proper escaping viaesc_attr()andesc_html().classes/helpers/FrmCssScopeHelper.php (4)
1-5: LGTM! Security check is in place.The ABSPATH check prevents direct file access, following WordPress security best practices.
102-178: LGTM! Unnest implementation is correct.The method properly handles selectors with and without the prefix, using
strposto check for prefix presence before removal. The use ofarray_filterto remove empty selectors is appropriate.
187-215: LGTM! Formatting logic is clean and handles both single and multi-line declarations appropriately.
225-262: String literal handling is correctly implemented.The escape character check at line 235 correctly short-circuits when
$i === 0to avoid negative index access. The fallback to$length - 1on unmatched braces (line 261) is reasonable for a CSS helper dealing with potentially malformed input.

27-88: Consider extracting helpers for at‑rules and rule blocks to reduce duplicationThe
whileloops innest()andunnest()are long, structurally very similar, and rely on//end ifcomments for readability. This makes them harder to maintain and reason about, especially as more edge cases around at‑rules and nesting are added.Consider extracting private helpers (e.g.,
process_at_rule()andprocess_rule_block()), or a shared parser that accepts a callback for selector transformation (prefix vs. unprefix). That would:
- Remove the need for matching
//end ifmarkers,- Centralize complex brace/at‑rule handling in one place, and
- Reduce the chance of fixing a bug in one method and forgetting the other.

classes/helpers/FrmCssScopeHelper.php (2)
17-23: Comment stripping vs. “preserve newlines” + class name safetyThe
preg_replace( '/\/\*.*?\*\//s', '', $css );call will also remove newline characters inside multi‑line comments, so the implementation doesn’t actually “preserve newlines” as the inline comment suggests. For large custom snippets this can change line offsets and overall formatting.Also,
$class_nameis interpolated directly into selectors; if it ever contains whitespace or other invalid characters, the generated CSS will break.Consider either:
- Adjusting the comment stripping to keep
\ncharacters (e.g., viapreg_replace_callbackthat blanks everything but newlines), or updating the comment to match behavior, and- Validating/normalizing
$class_nameearly so it’s guaranteed to be a safe CSS class token.
216-261: Fallback behavior infind_matching_brace()could be safer
find_matching_brace()correctly tracks nested braces and skips braces inside strings, but if no matching}is found it returns$length - 1. For malformed CSS this can cause callers to treat an arbitrary last character as the closing brace and slice an unexpected substring.To make failures easier to detect, consider returning a sentinel (e.g.,
-1ornull) and having callers either bail out or treat the rest of the string as the block explicitly, instead of silently guessing:- for ( $i = $open_pos + 1; $i < $length; $i++ ) { + for ( $i = $open_pos + 1; $i < $length; $i++ ) { … }//end for - - return $length - 1; + return -1;and then check for
-1innest()/unnest()before using the result.
