Cron Job在自定义插件中无法在Wordpress中工作

Question

我在WordPress自定义插件中添加了这个cronjob，但当我手动运行该函数时，它可以工作，但通过cronjob它不工作。这是我的密码！所有插件文件都已正确加载，没有显示任何错误。有人能帮我解决这个问题吗！我试了很多，但仍然不起作用。

<?php
if (!wp_next_scheduled('generateusedcarsfeed'))
{
wp_schedule_event(time() , '5mins', 'generateusedcarsfeed');
}
add_action('generateusedcarsfeed', 'generate_used_car_feed');
if (!wp_next_scheduled('generateusedcarsfeed'))
{
wp_schedule_event(time() , '5mins', 'generateusedcarsfeed');
}
add_action('generateusedcarsfeed', 'generate_used_car_feed');
// Getting all used cars with all data
function generate_used_car_feed(){
try{
// for opening the csv file
$file = fopen('all-cars-feed.csv', 'r');
fwrite($file, '');
$loop = new WP_Query($args);
chmod('all-cars-feed.csv', 0777);
// for creating array from csv file
$file="all-cars-feed.csv";
$csv= file_get_contents($file);
$array = array_map("str_getcsv", explode("n", $csv));
$json_csv_arr = json_encode($array);
$my_array_csv = json_decode($json_csv_arr, true);
// for getting used car list from databse, only take publish used car
global $wpdb;
$query = "SELECT wp_postmeta.post_id, wp_postmeta.meta_value FROM wp_postmeta 
INNER JOIN wp_posts ON wp_posts.id = wp_postmeta.post_id WHERE meta_key = 'car_registration_number' 
AND post_status = 'publish'";
$result = $wpdb->get_results($query);
$json_reg_num = json_encode($result);
$my_array = json_decode($json_reg_num, true);
print_r($my_array); 
foreach ($my_array as $value) {
$car_reg_array = $value['meta_value'];
$Post_id= $value['post_id'];
$isTrue=true;
$ch = fopen("all-cars-feed.csv", "r");
while($row = fgetcsv($ch)) {
if (in_array($car_reg_array, $row)) {
echo 'found</hr>';
$isTrue=false;
}
}
if($isTrue)
{
$wpdb->query(
'UPDATE   '.$wpdb->prefix.'posts SET post_status = "trash"
WHERE ID = "'.$Post_id.'"');
}
}
//fclose($file);
}
catch(Exception $e)
{
$txt = 'Message: ' . $e->getMessage();
$myfile = fopen("newfile.txt", "w") or die("Unable to open file!");
fwrite($fileLoger, $txt);
fclose($fileLoger);
}
}

我想知道这个5mins间隔是否真的存在于您的设置中。尝试添加此代码以确保它确实存在(如果它已经存在，它不会破坏东西(：

function add_custom_cron_schedules($schedules){
if (!isset($schedules["5mins"])) {
$schedules["5min"] = array(
'interval' => 5*60,
'display' => __('Every 5 minutes'));
}
return $schedules;
}
add_filter('cron_schedules','add_custom_cron_schedules');

如果您想检索当前可用的时间表，也可以使用wp_get_schedules()并检查是否存在某个键(如"5分钟"(。
