php - WordPress admin-ajax.php 错误请求 400

Question

您好，我正在保存以供网站中的后续功能使用 但当我单击按钮时，我收到 admin-ajax 错误请求

函数.php

function zumra_scripts() { wp_register_script( 'remove-prodduct-from-list', get_template_directory_uri() . '/js/remove-product.js', array('jquery'), false, true );     wp_localize_script( 'remove-prodduct-from-list', 'sfl_ajax', array( 'ajaxurl' => admin_url( 'admin-ajax.php' )) );
    if ( is_page('savelist') ) {
        wp_enqueue_script( 'remove-prodduct-from-list' );
    }

}
add_action( 'wp_enqueue_scripts', 'zumra_scripts' );

保存供以后使用.php

  <?php

add_action( 'wp_ajax_my_action', 'my_action' );

function my_action() {
    $user =         $_POST['user'];
    $post_id =      $_POST['post_id'];
    $response =     $_POST['saveForLater'];
    $response .= '<a href="'. site_url("/savelist") .'">'. __( 'Browse Savelist', 'zumra' ) .'</a>';

    add_user_meta( $user, 'product_id', $post_id);

    echo $response;

    wp_die(); // this is required to terminate immediately and return a proper response
}

add_action( 'wp_ajax_remove_product_from_list', 'remove_product_from_list' );
function remove_product_from_list() {
    $user =     intval( $_POST['user'] );
    $product =  intval( $_POST['product'] );

    delete_user_meta( $user, 'product_id', $product);

    wp_die(); // this is required to terminate immediately and return a proper response
}

add_action( 'wp_ajax_move_to_cart', 'move_to_cart' );
function move_to_cart() {
    $user =     intval( $_POST['user'] );
    $product =  intval( $_POST['product'] );

    delete_user_meta( $user, 'product_id', $product);

    // do_action( 'woocommerce_ajax_added_to_cart', $product );
    // wc_add_to_cart_message( $product );

    wp_die(); // this is required to terminate immediately and return a proper response
}

保存供以后使用.js

    jQuery(document).ready(function($) {
    $('.ajax-form').on('submit',function(e){
        e.preventDefault();
        var data = {
            'action': 'my_action',
            'saveForLater': sfl_ajax.response,
            'user':         sfl_ajax.user,
            'post_id':      sfl_ajax.post_id,
            'product_id':   sfl_ajax.user_product,
        };

        // since 2.8 ajaxurl is always defined in the admin header and points to admin-ajax.php
        jQuery.post(sfl_ajax.ajaxurl, data, function(response) {
            $('.save-for-later').html(response);
        });
    });
});

我不知道我做错了什么 每次我单击“添加以保存以供稍后使用”按钮时，我都会收到错误 admin-ajax.php 400

尝试在您的 php 文件中使用此代码:

function zumra_scripts() {
          wp_register_script( 'remove-prodduct-from-list', get_template_directory_uri() . '/js/remove-product.js', array('jquery'), false, true );

          wp_localize_script( 'remove-prodduct-from-list', 'sfl_ajax', array(
            'ajaxurl'         => admin_url( 'admin-ajax.php' ),
            'user'.           => get_current_user_id(),
            'post_id'         => get_the_ID(),
            'user_product'    => get_the_ID(), // custom function if any
            'response'        => your_custom_function(), // if any
          );

          if ( is_page( 'savelist' ) ) {
             wp_enqueue_script('remove-prodduct-from-list');
          }
}

add_action( 'wp_enqueue_scripts', 'zumra_scripts' );
