从 DB wordpress 中删除带有 id 的图像

Question

我想从 PHPMyAdmin DB 中删除带有 ID 的图像。带有图像的表是wp_posts，ID 称为post_parent。 连接到 ajax 并应删除图像的操作：

add_action( 'wp_ajax_delete_image_admin', 'delete_image_admin' );
function delete_image_admin(){

    $deleteId = $_POST['deletedId'];

    
    
    $return = array(
    'message'   => 'Сохранено',
    'ID'        => $_POST['deletedId'],
);
wp_send_json( $return );
};

Ajax（它工作正常）：

<script>
jQuery(document).ready(function($) {
  $(document).on('click', '.image-remove-btn', function (e){
    e.preventDefault();
    var img = $(this).closest('.thumbs');
    var id = img.find("img").data('id');
    $.ajax({
        url: "/wp-admin/admin-ajax.php",
        type: 'POST',
        data: {deletedId : id,
        action: "delete_image_admin"},
        success: function( data ) {
            img.remove();
        }    
    });
  });
});
</script>

以下代码应该从 wp_posts 表中删除图像：

add_action('wp_ajax_delete_image_admin', 'delete_image_admin');
add_action('wp_ajax_nopriv_delete_image_admin', 'delete_image_admin');
function delete_image_admin(){
    if (!empty($_POST['deletedId'])) {
        global $wpdb;

        $deleteId = $_POST['deletedId'];

        $table = $wpdb->base_prefix . "posts";
        $wpdb->delete($table, [
            'ID' => $deleteId,
        ]);

        echo 'Image deleted';

        wp_die();
    }
};
