I would filter which posts go into the option, that’s light enough processing that it can be done on that end. To get the content of the post you can use get_post( $v );. To get the metavalues for the post you can use get_post_custom( $v );. To update the meta values you will use … Read more
The cron event needs to be registered on the plugin activation hook like so: register_activation_hook( __FILE__, ‘activate_cron’ ); function activate_cron() { wp_schedule_event( current_time( ‘timestamp’ ), ‘hourly’, ‘the_function_to_run’ ); } The the_function_to_run defined in the wp_schedule_event needs to be your function that you want to run at the time interval. Note: When you say something is … Read more
You are using the system cron to trigger a function hooked into the AJAX API, not, as your title reads, using “admin-ajax.php to run a real cron job”. You are doing exactly the opposite of what you wrote in the title (I’d advise editing that). Yes, that is perfectly fine. I have advised using the … Read more
This is what normal query run by wp_get_associated_nav_menu_items() looks like: SELECT wp_posts.* FROM wp_posts INNER JOIN wp_postmeta ON ( wp_posts.id = wp_postmeta.post_id ) WHERE 1 = 1 AND wp_posts.post_type=”nav_menu_item” AND (( wp_posts.post_status <> ‘trash’ AND wp_posts.post_status <> ‘auto-draft’ )) AND (( wp_postmeta.meta_key = ‘_menu_item_object_id’ AND Cast(wp_postmeta.meta_value AS CHAR) = ‘3111’ )) GROUP BY wp_posts.id ORDER … Read more
Yes, in my opinion that’s exactly the right way to extend the default schedule timings. I would be a little more informative with the display value but I think that is only example code. However, one important thing should be taken into account. The default WordPress schedule implementation that is invoked as a side effect … Read more
It is set_site_transient, not set_site_site_transient. You should be aware that a single user will still wait that half a minute for this to complete. wp_cron does not run on clock time. It runs when a user visits the site. If you have the ability to create a system cron job then hook your callback to … 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
The WordPress cron is run by the wp_cron() function, which is hooked to run on the init hook, which runs on every page load. wp_cron() is defined in wp-includes/cron.php and hooked in wp-includes/default-filters.php. The wp_cron() function kicks off a wp_remote_post() request to /wp-cron.php. Some server configurations prevent scripts sending a request to the same domain … 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
Don’t use global $post. Everything you need should be passed into the function in the $data and $postarr parameters. Secondly, you have to return the $data in all cases. What you are doing now is effectively erasing data for everything but your profile post type. You need to reorganize a bit: function reset_post_date_wpse_121565($data,$postarr) { if … Read more
