1443-1447: LGTM! Improved array handling safety.
The changes enhance the robustness of array value handling by:
- Using safer empty checks for attribute conditions
- Using
FrmAppHelper::safe_implode()to prevent array-to-string conversion warnings
1443-1447: LGTM! Well-handled method deprecation.
The deprecated method is properly handled with:
- Clear deprecation notice
- Correct replacement method reference
- Maintained backward compatibility

1039-1039: LGTM! Safer array-to-string conversion implemented.
The change from direct implode() to FrmAppHelper::safe_implode() improves safety by properly handling array-to-string conversion and preventing potential PHP warnings.

1443-1447: Fix code indentation.
The indentation of this code block appears inconsistent with the surrounding code style.
Apply this diff to fix the indentation:
- if ( ! empty( $atts['show'] ) && isset( $value[ $atts['show'] ] ) ) {
- $value = $value[ $atts['show'] ];
- } elseif ( empty( $atts['return_array'] ) ) {
- $sep = isset( $atts['sep'] ) ? $atts['sep'] : ', ';
- $value = FrmAppHelper::safe_implode( $sep, $value );

2120-2132: LGTM! Consider enhancing the docblock.
The implementation looks good and safely handles nested arrays before imploding. The method effectively prevents "Array to string conversion" warnings.
Consider adding @param tags to the docblock for better code documentation:
/**
* Flatten an array before imploding it to avoid Array to string conversion warnings.
*
* @since x.x
+ * @param string $sep The separator string
+ * @param array $array The array to implode
* @return string

1039-1039: LGTM! Safer array to string conversion implemented.
The change from implode to FrmAppHelper::safe_implode improves safety by properly handling array to string conversion, which aligns with the PR objective of making implode code safer.
1039-1039: Verify other potential unsafe implode usages.
Let's verify if there are other places in the codebase that might benefit from using safe_implode.
✅ Verification successful
Let me analyze the findings from the shell script results:
-
The
safe_implodeimplementation exists inFrmAppHelperclass and is being used in a few places:FrmFieldsHelper::replace_content_shortcodesFrmFieldType::get_value_to_save
-
Looking at the implementation of
safe_implode, it flattens the array before imploding:
public static function safe_implode( $sep, $array ) {
$array = self::array_flatten( $array );
return implode( $sep, $array );
}-
Most direct
implodeusages found are:- In test files (safe to ignore)
- For joining CSS classes, HTML attributes, query parts (safe usage)
- For display/formatting purposes where the input is controlled
- For internal data processing where the input is validated
-
The current change uses
safe_implodein shortcode processing which is the right approach for user-provided data.
No issues found with implode usage patterns.
The codebase appears to use implode appropriately:
- Direct
implodeis used for trusted data and internal processing safe_implodeis used where array values could contain nested arrays or user data- The current change correctly uses
safe_implodefor shortcode processing
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Search for direct implode calls that might need to be replaced with safe_implode
# Test: Search for direct implode calls
echo "Searching for potential unsafe implode calls..."
rg "implode\(" --type php -C 2 | grep -v "safe_implode"
# Test: Verify the safe_implode implementation exists
echo "Verifying safe_implode implementation..."
rg "safe_implode" --type php -C 2
