If you’re using the most recent version of WordPress, there are two ways you can update your plugins by just clicking a button (OK, maybe a couple, but it’s still really easy). Under Dashboard in your WP admin, there will an Updates option. Click on that and you should see something like this: Choose Select … Read more
While the idea that you are “developing some scrapping plugin” is sketchy and off-putting, the general question is “How do I fire code using system cron jobs?” and that is a valid question. You don’t need to jump through hoops to load WordPress. Set up an AJAX API callback… function fire_cron_job_wpse_144051() { // fire your … Read more
You do not need to use raw SQL, WordPress already provides WP_User_Query, and even provides examples of date based queries, for example the official docs say that this will retrieve all users registered within the last 12 hours: $args = array( ‘date_query’ => array( array( ‘after’ => ’12 hours ago’, ‘inclusive’ => true ) ) … Read more
OK, so first of all you’ll need to add your own WP_Schedule event: add_action( ‘wp’, function () { if (! wp_next_scheduled ( ‘mark_posts_as_featured_event’ )) { wp_schedule_event(time(), ‘daily’, ‘mark_posts_as_featured_event’); } } ); function mark_posts_as_featured_event_callback() { // if there are sticky posts in our CPT, unstick them $sticked_post_ids = get_option( ‘sticky_posts’ ); if ( ! empty ) … Read more
WP-Cron is not a guaranteed time task scheduler. The trigger for WP-Cron is somebody visiting the site itself, so if nobody visits the site at midnight, then the job doesn’t run until somebody does visit the site later. Similarly, if you use a whole page caching mechanism like WP-Super-Cache, then anonymous users will not really … Read more
I found a great solution here: Trigger a custom wordpress plugin with a linux cron My path was /usr/bin/wp so check your server. You can just add your function to a file, and using the wp bin script you don’t need to add anything to your php file to use WordPress functions. I was able … Read more
I have confirmed with my host that this is a normal occurrence in access logs when running WordPress crons. Also, since I disabled ALTERNATE_WP_CRON I didn’t come across any actual (live) URLs with the ?doing_wp_cron attached to them.
You don’t have to declare the constructor public, just the action hook function. Example: <?php /* Plugin Name: Singleton Action */ class Singleton_Demo { /** * @static $instance Objekt * @access private; */ private static $_instance = NULL; protected function __construct() {} private final function __clone() {} public static function getInstance() { if ( self::$_instance … Read more
WP-Cron doesn’t run in the admin scope – remove your if ( is_admin() ) condition.
Here’s how I would go about doing this: First create a file with a hash for the file name within your theme directory – this one is md5(‘foobar’): 3858f62230ac3c915f300c664312c63f.php Within that file would be something like this: //Use the file name as an API key of sorts $file = explode(‘.’, basename(__FILE__)); $key = $file[0]; //Trigger … Read more
