 * Hello,
 * I found a fatal error in Link Whisper related to Elementor integration.
 * Environment:
    - WordPress
    - Elementor
    - PHP 8.3
    - Link Whisper 0.9.4
 * Fatal error:
 *     ```wp-block-code
       Fatal error: Uncaught Error: Call to undefined method
       Wpil_Editor_Elementor::appendProcessableValue()
       ```
   
 * File:
   `core/Wpil/Editor/Elementor.php`around line 130.
 * The issue occurs while saving Elementor content.
 * Stack trace indicates:
 *     ```wp-block-code
       Elementor save
       -> Link Whisper content processing
       -> Wpil_Editor_Elementor::getProcessableData()
       -> self::appendProcessableValue()
       ```
   
 * I checked the plugin source and:
    - `Wpil_Editor_Elementor` does not extend another class
    - there is no imported trait
    - `appendProcessableValue()` is not defined anywhere in the plugin
    - the method also does not exist in previous versions
 * So the current code path calls a non-existent static method.
 * This seems to be an incomplete refactor or a missing method in the release package.
 * Could you confirm and provide a fix?
 * Thanks.

 * Hi,
 * I had the same issue with Link Whisper Free 0.9.4 and Elementor.
 * The fatal error happens because the plugin calls this method:
 * `Wpil_Editor_Elementor::appendProcessableValue()`
 * but this method is not declared in the plugin files.
 * The error is in:
 * `wp-content/plugins/link-whisper/core/Wpil/Editor/Elementor.php`
 * In my case, the issue happened when saving an Elementor page. Link Whisper tried
   to process the Elementor content and crashed because the method was missing.
 * Temporary fix:
 * I added the missing method inside the `Wpil_Editor_Elementor` class in:
 * `core/Wpil/Editor/Elementor.php`
 * Code added:
 *     ```wp-block-code
       private static function appendProcessableValue(&$processable_data, ...$values)
       {
           if (!is_array($processable_data)) {
               $processable_data = array();
           }
   
           foreach ($values as $value) {
               if (is_array($value)) {
                   foreach ($value as $sub_value) {
                       self::appendProcessableValue($processable_data, $sub_value);
                   }
                   continue;
               }
   
               if (is_object($value)) {
                   $value = wp_json_encode($value);
               }
   
               if (is_scalar($value)) {
                   $value = trim((string) $value);
   
                   if ($value !== '') {
                       $processable_data[] = $value;
                   }
               }
           }
   
           return $processable_data;
       }
       ```
   
 * After adding this method, Elementor pages could be saved again.
 * Please note: this is only a temporary patch because it modifies a plugin core
   file. It may be overwritten during a future Link Whisper update. The best solution
   would be an official fix from the plugin author.
