嗨，我使用此插件创建事件https://wordpress.org/plugins/modern-events-calendar-lite/ 这是在我的android应用程序上发送通知。https://github.com/dream-space/wp-fcm

我对插件进行了修改，以便在3天前发送即将发生的事件的提醒通知。修改如下所示。

`

 function fcm_main_get_option_event(){
  $options = get_option(\'fcm_event_setting\');
  if(!is_array($options)){
    $options = array(
        \'event_check\' => 0,
    );
 }

return $options;
}

if (!wp_next_scheduled(\'my_task_hook\')) {
wp_schedule_event( time(), \'daily\', \'my_task_hook\' );
}
add_action ( \'my_task_hook\', \'my_task_function\' );

和发送通知的功能：

`

function my_task_function() {
$options  = get_option(\'fcm_event_setting\');
 //  $is_send_notif = false;
if(!empty($options[\'event_check\'])) {
   $is_send_notif = true;
  $args = array(  
    \'post_type\' => \'mec-events\',
    \'post_status\' => \'publish\',
    \'posts_per_page\' => -1, 
  );

$loop = new WP_Query( $args ); 

    
while ( $loop->have_posts() ) : $loop->the_post(); 
$datetime2 = date("Y-m-d"); 
$my_meta = get_post_meta(get_the_ID(), \'mec_start_date\', true ); 
$diff = strtotime($my_meta) - strtotime($datetime2);
    $gap = abs(round($diff / 86400)); 

    
    if($gap == \'3\'){
         $is_send_notif = true;
         $title = \'Потсетување\';
         $event = "POTSETNIK 1";
        $body    = \'For \'.$gap.\' days :\' .get_the_title();

    }


    if($is_send_notif == true){
    $message = array(
        \'title\'     => $title,
        \'content\'   =>  \'For \'.$gap.\' days:\' .get_the_title()

    );

    $total = fcm_data_get_all_count();
    if($total <= 0) return;

    $respon  = fcm_notif_divide_send("", $total, $message);

    fcm_data_insert_log($title, $content, "ALL", $event, $respon[\'status\']);
}
    endwhile;
wp_reset_postdata();
}
}

这项工作，但在活动前3天和活动后3天发送通知。

问题出在哪里。

谢谢
