我是jQuery Ajax的初学者，所以请耐心听我说。我的Ajax响应似乎没有加载，但我的更改正在保存。但是在管理ajax上给了我这个错误。php“call\\u user\\u func（）期望参数1是有效的回调，未找到函数“\\u update\\u post\\u teru count”或无效的函数名”这是我的函数，你能指出我做错了什么吗？

add_action( \'wp_ajax_nopriv_save_sort\', \'ccmanz_save_reorder\' );
add_action(\'wp_ajax_save_sort\',\'ccmanz_save_reorder\');
function ccmanz_save_reorder() { //checking

//verify user intent
check_ajax_referer( \'wp-job-order\', \'security\' ); // this comes from wp_localize_script() in hrm-jobs.php
//capability check to ensure use caps
if ( ! current_user_can( \'manage_options\' ) ) {
    wp_die( __( \'You do not have permission to access this page.\' ) );
}

$order   = explode( \',\', $_POST[\'order\'] );
$counter = 0;

foreach ( $order as $item_id ) {
    $post = array(
        \'ID\'         => (int) $item_id,
        \'menu_order\' => $counter,
    );

    wp_update_post( $post );
    $counter ++;
}
wp_send_json_success(\'POST SAVED\');
}

jQuery(document).ready(function($) {

sortList = $( \'ul#custom-type-list\' ); //store
var animation = $ ( \'#loading-animation\' );
var pageTitle = $ ( \'div h2\');

sortList.sortable({

update: function ( event, ui) {
    animation.show();

    $.ajax({

            cache: false,

            data:{

            },
        success: function( response ) {
