我想对前端登录用户使用wp-ajax，但显示发现的302错误并调用主页。它对于管理员用户和未登录用户都可以正常工作。

以下是网络日志截图：

add_action(\'wp_ajax_add_sale\', \'add_sale\');
add_action(\'wp_ajax_nopriv_add_sale\', \'add_sale\');

<?php
function add_sale() {
    die("hello");
    $salevehicleid = $_POST[\'salevehicleid\'];
    $saleuserhidid = $_POST[\'saleuserhidid\'];
    $saleusername = $_POST[\'saleusername\'];
    $saleuseremail = $_POST[\'saleuseremail\'];

    $saledate = date(\'Y-m-d H:i:s\');

    $letsaleplaced = true;

    $response = array();

    // $saleuserhidid = (int)0;

    // if(is_user_logged_in()){
    //     $user_id = get_current_user_id();
    //     if ($user_id == 0) {
    //         $saleuserhidid = (int)0;
    //     } else {
    //         $saleuserhidid = (int)$user_id;
