You don’t need a plugin for this, a complete cron system is built into wordpress. If you don’t do anything, then wordpress is already running a lazy man’s cron job. Which means that it’s using your page hits to run the cron as close to your schedule as possible. Or you can choose to disable … Read more
If you look at the Cache Images plugin’s thumbnails page on the WordPress plugin directory it looks like this feature already exists within the plugin. In the admin section of your site go to Settings→Media there should be an option to cache images when posts are saved.
First of all, it’s best not to include wp-blog-header.php. Instead, set the cron job to your homepage URL with a ?mycustomcron=true variable appended (eg: http://example.com/?mycustomcron=true. Then we will check for the existance of this variable when the page loads: function wpse_103127_check_cron() { if ( isset( $_GET[‘mycustomcron’] ) ) { // things to do on cron … Read more
Well, I don’t think you can do this with cron. Browser sends request to server and gets response. It isn’t connected permanently to your server. So if you want to refresh page which is already displayed in browser, you have to force browser to send request for this page one more time (do refresh). Another … Read more

0 0,4,8,12,16,20 * * * /cmd.sh That’s probably how I would do it. This will run the job every 4 hours, on the hours of 00:00, 04:00, 08:00 12:00, 16:00, 20:00. This is just a little more verbose way of writing */4, but it should work the same.
I always found that logging cron job execution to a file is very helpful. Otherwise you have no idea if it’s working right. Just have your code open a file, write a timestamp, and close. Something simple like: $logfile = $_SERVER[‘DOCUMENT_ROOT’].’/CRON.txt’; $handle = fopen($logfile , ‘a’) or die(‘Cannot open file: ‘.$logfile ); $data=”cron task called … Read more
wget was fine. The client’s theme had a coming soon feature that was keeping the cron from processing.
Use WordPress Transient API instead. This should be something like this (modified your existing shortcode function). function skips_get_random_tags() { $transient_name=”skips_random_tag”; $transient_expiration = 60 * 60 * 24; // 1 day if ( false === ( $tag = get_transient( $transient_name ) ) ) { // tag isn’t found in transient so get it from WP database … Read more
I think your problem may be in the use of $post->ID. In your code $post is an undefined variable. As you are inside a loop, try get_the_ID() instead of $post->ID: $post_ID = get_the_ID(); $request_start_time = get_post_meta( $post_ID, ‘_simple_start_date’, true ); if (date(‘Ymd’) == date(‘Ymd’, $request_start_time)){ $current_user = $post->post_author; $request_date = get_post_meta( $post_ID, ‘_simple_start_date’,true ); $request_year … Read more
