So, I want to run a function on my plugin from crontab. For the example, I want to run it every day at 1:10am
function my_cronjob_action () {
//this function is in my plugin
// code to execute on cron run
syslog(LOG_DEBUG, 'executed by unix cron');
} add_action('my_cronjob_action', 'my_cronjob_action');
I’ve disabled wp-cron by adding define( 'DISABLE_WP_CRON', true );
into wp-config.php
what’s the next step so the function can be executed from crontab?
Thank you before.

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 to run this from SSH / putty but I cannot get it to work as a cron job currently. I’l update if I figure out how.
The solution I came up with here goes as follows:
- Installed WP-CLI and made use of the eval-file command.
- Converted my wordpress plugin to a standalone script.
- In the standalone script, I initiated wordpress so i didn’t have to modify most of it. I just removed my the activation hooks and other wordpress plugin specific code.
- My final cron line looked like this:
/usr/local/bin/wp –path=”/var/www/vhosts/path/to/site/” eval-file /var/www/vhosts/path/to/site/and/file/location/standalone-cron-send-email.php- For security purposes, I’ve added this to the top of the script so outside intruders can not run the script. Only WP-CLI can run the script otherwise the meant to be run from command line message is returned to the browser.
if( php_sapi_name() !== ‘cli’ ) { die(“Meant to be run from command line”); }
