我试图使用ajax调用在wordpress中向数据库添加一些数据。
代码如下：
<?php
function saveRefreshData(){
global $wpdb;
$table_name = $wpdb->prefix . "refresh";
$state = $_POST["state"];
$duration = $_POST["duration"];
$only_for_facebook = $_POST["only_for_facebook"];
$start_at_1 = $_POST["start_at_1"];
$start_at_db_1 = !empty($start_at_1) ? "'$start_at_1'" : "NULL";
$active_duration_1 = !empty($_POST["active_duration_1"]) ? $_POST["active_duration_1"] : "NULL";
$repeat_daily_1 = $_POST["repeat_daily_1"];
$start_at_2 = $_POST["start_at_2"];
$start_at_db_2 = !empty($start_at_2) ? "'$start_at_2'" : "NULL";
$active_duration_2 = !empty($_POST["active_duration_2"]) ? $_POST["active_duration_2"] : "NULL";
$repeat_daily_2 = $_POST["repeat_daily_2"];
$start_at_3 = $_POST["start_at_3"];
$start_at_db_3 = !empty($start_at_3) ? "'$start_at_3'" : "NULL";
$active_duration_3 = !empty($_POST["active_duration_3"]) ? $_POST["active_duration_3"] : "NULL";
$repeat_daily_3 = $_POST["repeat_daily_3"];
$start_at_4 = $_POST["start_at_4"];
$start_at_db_4 = !empty($start_at_4) ? "'$start_at_4'" : "NULL";
$active_duration_4 = !empty($_POST["active_duration_4"]) ? $_POST["active_duration_4"] : "NULL";
$repeat_daily_4 = $_POST["repeat_daily_4"];
if($wpdb->query($wpdb->prepare ("UPDATE $table_name SET
state = ". $state .",
duration = ". $duration .",
only_for_facebook = ". $only_for_facebook .",
start_at_1 = " . $start_at_db_1 . ",
active_duration_1 = ". $active_duration_1 .",
repeat_daily_1 = ". $repeat_daily_1 .",
start_at_2 = ". $start_at_db_2 .",
active_duration_2 = ". $active_duration_2 .",
repeat_daily_2 = ". $repeat_daily_2 .",
start_at_3 = ". $start_at_db_3 .",
active_duration_3 = ". $active_duration_3 .",
repeat_daily_3 = ". $repeat_daily_3 .",
start_at_4 = ". $start_at_db_4 .",
active_duration_4 = ". $active_duration_4 .",
repeat_daily_4 = ". $repeat_daily_4 .",
added_time = now()"))){
wp_send_json_success( 200 );
}else{
wp_send_json_error( 400 );
}
}
add_action("wp_ajax_save_refresh", "saveRefreshData");
?>
但我收到以下错误：

直到最后一次wordpress更新，一切都很好。
有什么想法吗？
