Wordpress 管理员 Ajax 400（错误请求）

Question

我使用过 WordPress Admin Ajax，控制台显示 400（错误请求）

    jQuery('#submitid').click(function(e){
    e.preventDefault();
    //var newCustomerForm = jQuery(this).serialize();

    jQuery.ajax({
        type: "POST",
        url: "wp-admin/admin-ajax.php",
        data: {status: 'status', name: 'name'},
        success:function(data){
             jQuery("#result").html(data);
        }
    });
});

如果您希望 Wordpress AJAX 流程正常工作，则应遵循一些基本要点：

1.在functions.php中添加您想要从前端调用的操作：

function logged_in_action_name() {
  // your action if user is logged in
}
function not_logged_in_action_name() {
  // your action if user is NOT logged in
}

add_action( 'wp_ajax_logged_in_action_name', 'logged_in_action_name' );
add_action( 'wp_ajax_nopriv_not_logged_in_action_name', 'not_logged_in_action_name' );

2.在functions.php中注册本地化对象

// Register the script
wp_register_script( 'some_handle', 'path/to/myscript.js' );

// Localize the script with new data
$some_object = array(
    'ajax_url' => admin_url( 'admin-ajax.php' )
);

wp_localize_script( 'some_handle', 'ajax_object', $some_object );

// Enqueued script with localized data.
wp_enqueue_script( 'some_handle' );

3.在前端创建AJAX请求

// source: https://codex.wordpress.org/AJAX_in_Plugins
var data = {
  'action': 'not_logged_in_action_name',
  'whatever': 1234
};

jQuery.post( ajax_object.ajax_url, data, function( response ) {
  console.log( response );
}
