为elementor创建了一个自定义的小部件，可以使用 AJAX 一次将追加销售项目添加到购物车中。为此，我利用了wocoomerce追加销售产品的功能和折扣，我创建了ACF字段来保存优惠券信息，并将在结帐时应用。所有的前端工作正常，但当我点击elementor页面生成器更新500错误弹出，但更新发生。只是担心如果下面的代码有任何安全问题。
这是我的自定义控件php文件：

<?php

/**

 * 
 * Elementor bundles  item widget to display in the single product page
 */
//  namespace WPC\Widgets;
//  use Elementor\Controls_Manager;
if ( ! defined( 'ABSPATH' ) ) {
    exit; // Exit if accessed directly.
}
 class Elementor_Widget_3 extends \Elementor\Widget_Base
 {
  
    public function get_name() {
        return 'Bundle item'; 
    }

    public function get_title() {
        return esc_html__( 'Bundle item', 'custom-widget');
    }

    public function get_icon() {
        return 'eicon-header';
    }

    public function get_custom_help_url() {}

    public function get_categories() {
        return ['basic'];
    }

    public function get_keywords() {}

        ];

    }

    public function get_style_depends() {
        wp_register_style( 'widget-style-3', '/wp-content/themes/astra-child/custom-widgets/custom-widgets-assets/css/custom-bundle-item.css', __FILE__ );
        return

        );
        $this -> add_control(

                 'default' => 'Bundles items'
            ]
            );
          
            $this->end_controls_section();
    }

    protected function render() {
       
       global $product;
       $product_id = get_the_ID($product);
       $product = wc_get_product($product_id);

       $product_coupons =  $coupons_value['value'];
       $product_coupon = $coupons_value['label'];

       ;
    }
}
 

    protected function content_template() {}
}

这是我 AJAX 文件：

// Multi Ajax adda to cart
$ = jQuery;
function multiAddToCart( bundle ) {
    $.ajax({
        url: '/wp-admin/admin-ajax.php/',
        type: 'POST', 
        dataType: 'JSON',
        data: {
            'action': 'multi_add_to_cart',
            'discount': coupons,
            'items' : Object.assign({}, bundle)
        },
        success : function(response) {
            $(document.body).trigger('wc_fragment_refresh'); // Refresh cart fragments
        },
        beforeSend: function (response) {
            $('#add-to-cart-bundle').html("Adding to cart");
        },
        complete: function (response) {
            $('#add-to-cart-bundle').html("Added to cart").prop('disabled', true).removeClass('add-to-cart-bundled').addClass('added-to-cart-bundled');
           
        },
        error : function(error) {
            console.log(error);
        }
    });
}
var itemCoupons = $('.bundled-item-ids').data('product-profile');
var coupons = itemCoupons.toString();
$( '#add-to-cart-bundle' ).on('click', function() {
    bundle = [];
    $('.selected-item').each(function(){
                     if($(this).prop('checked')== true)
                     {
                         var cart_item = $(this).data('product-id');
                         var cart_quantity = $(this).data('product-quantity');
                         bundle.push({ product_id: cart_item, quantity: cart_quantity });
                     }
                 })

    multiAddToCart( bundle);
});

这是我的服务器端脚本

<?php
add_action('wp_ajax_multi_add_to_cart', 'multi_ajax_add_to_cart');
add_action('wp_ajax_nopriv_multi_add_to_cart', 'multi_ajax_add_to_cart');

function multi_ajax_add_to_cart() {
    if (isset($_POST['items']) ) {
        $items = $_POST['items'];
        $discount = $_POST['discount'];
        
        if ( ! is_array( $items ) || empty( $items ) ) {
            wp_send_json_error( 'Invalid items list' );
        }
    
        // Add each item to the cart
        foreach ( $items as $item ) {
            $product_id   = absint( $item['product_id'] );
            $quantity     = absint( $item['quantity'] );
    
            // Validate the product ID
            if ( ! $product_id ) {
                continue;
            }
            
            // Add the item to the cart
            WC()->cart->add_to_cart( $product_id, $quantity);

        }
       
            $previous_coupons =  WC()->cart->get_applied_coupons();
            WC()->cart->remove_coupons($previous_coupons);

            // Apply the discount code
            $result = WC()->cart->apply_coupon($discount);
            if ( $result === true ) {
              // Discount applied successfully
              wc_add_notice( __( 'Discount code applied successfully.', 'woocommerce' ) );

            } 
           else {
            // Handle error message
            wc_add_notice( __( 'Invalid discount code.', 'woocommerce' ), 'error' );
          }
        // Get the updated cart fragments
        $fragments = WC()->cart->get_cart_for_session();
    
        // Send the response
        wp_send_json_success( array(
            'fragments' => $fragments,
            'cart_hash' => WC()->cart->get_cart_hash(),
        ) );
    }
    die();
}

我确实尝试增加内存限制，但没有运气，我也有其他自定义小部件工作正常。
最后这是我的错误日志：

试着在wp-config中启用错误日志记录，并查看错误是什么。您可以通过更改以下内容来启用：

define( 'WP_DEBUG', true );    
define( 'WP_DEBUG_LOG', true );

然后检查在wp-content中创建的错误日志文件。
正如您所建议的，这可能是Elementor的内存限制，我会在php.ini中设置为512 M。
