Fatal Error in Bulk Edit

I’ve found a critical bug in the Bulk Edit feature of Dokan Pro.
When trying to use bulk editing on products, the site crashes with the following error:

Uncaught ArgumentCountError: Too few arguments to function WeDevs\DokanPro\ProductBulkEdit::bulk_edit_save_product_brands(), 1 passed in /wp-includes/class-wp-hook.php on line 326 and exactly 2 expected Root cause

Inside wp-content/plugins/dokan-pro/includes/ProductBulkEdit.php, at line 33, the hook is registered without specifying the number of arguments:

add_action( 'dokan_before_bulk_edit_save_single_item', [ $this, 'bulk_edit_save_product_brands' ] );

But the callback actually requires two arguments ($product, $request_data). Because WordPress defaults to only 1, this results in a fatal error. Correct fix

The hook should be registered like this:

add_action( 'dokan_before_bulk_edit_save_single_item', [ $this, 'bulk_edit_save_product_brands' ], 10, 2 ); Temporary workaround

Until this is fixed in core, I’m using a small MU-plugin that removes and re-registers the callback properly. Here’s the code:

<?php /** * Plugin Name: Dokan Bulk Edit Fix – Accepted Args */ add_action('plugins_loaded', function () { $hook = 'dokan_before_bulk_edit_save_single_item'; global $wp_filter; if ( empty($wp_filter[$hook]) || !($wp_filter[$hook] instanceof WP_Hook) ) { return; } $hook_obj = $wp_filter[$hook]; foreach ($hook_obj->callbacks as $priority => $callbacks) { foreach ($callbacks as $id => $cb) { $fn = $cb['function']; $accepted = $cb['accepted_args'] ?? 1; if (is_array($fn) && is_object($fn[0]) && $fn[1] === 'bulk_edit_save_product_brands' && method_exists($fn[0], 'bulk_edit_save_product_brands') && $accepted < 2) { // Remove the wrong registration unset($hook_obj->callbacks[$priority][$id]); // Re-register correctly with 2 args add_action($hook, [$fn[0], 'bulk_edit_save_product_brands'], $priority, 2); } } } }, 20); Request

Please adjust the hook registration in the official Dokan Pro codebase to avoid this fatal error for all users.

Thanks for your support!
