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
And what do you think it should do? Either you posted here only part of your code or it can’t do anything that makes sense. The only thing this function does is assigning a value to a variable. This SQL query is never executed, because you don’t execute it anywhere in your code. I guess … Read more
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

Looking at your function: function my_task_function() { $test_score update_field(‘score’, $test_score ); } $test_score is not defined here, it should be $test_score=”something”; Left the way you have it now will generate php warnings. Also the update_field function used in this context (in a cron) will require you to pass a third argument specifying which post/page contains … Read more

WP cron tasks execute in completely separate process from page load. Nothing from the task’s output will be ever seen by users. That’s the purpose of them, to run scheduled task without interfering with site itself. If you want to output to the page periodically you will have to build it in other way. You … Read more
It think that your problem is the you are passing the post ID as url parameter to facebook API: $url = get_the_ID(); Also, as get_posts return an array of post objects, you could use this code: $posts = get_posts(array(‘numberposts’ => -1) ); foreach($posts as $post) { $url = get_permalink( $post->ID ); $fbcount = json_decode( file_get_contents( … Read more
I’ve actually made a plugin called Social Metrics Tracker which does exactly what you are trying to achieve. Please also feel free to read the source code on GitHub.
