Descripción

Cron not running when you expect? This plugin may help. Also provides insight into WP-Cron exactly like the Cron View plugin.

This plugin will visit your site every minute and thereby ensure that your cron jobs run on time. It is mostly intended for people who can’t use real cron for some reason.

Note: This is the exact same plugin that was previously sold on Code Canyon.

Preguntas frecuentes

What is a “fake visit”?

WordPress Cron only runs when someone visits your site. A fake visit causes a page to load without needing a real person to visit.
For the more technically minded, the plugin spawns a PHP sub-process that loops indefinitely and loads wp-cron.php each minute. This causes WP Cron to be triggered in exactly the same way it would if a real user was visiting your site.

Can the interval be adjusted?

Yes. However, you’d need to modify the plugin code. The reason is that WordPress won’t allow cron jobs to run more frequently than 1 minute, and running every minute has very little downside.
If you really must tinker with it, hook a filter into ‘imcron_interval_id’ like this (change ‘123’ to your desired interval time):

add_filter( 'cron_schedules', 'add_my_own_interval' );
function add_my_own_interval() {
    $seconds = 123;
    $interval['my_own_interval'] = array('interval' => $seconds, 'display' => sprintf( '%d seconds', $seconds ) );
    return $interval;
}

add_filter( 'imcron_interval_id', 'set_imcron_interval' );
function set_imcron_interval() {
    return 'my_own_interval';
}

You’ll need to stop and re-start on the settings page to get the new interval to take effect.

Will it list every scheduled event in the admin, including those scheduled by plugins or themes?

Yes, it includes all events scheduled within WordPress at the time.

What is PHP requirement of using this? Is it PHP exec() enable?

If your WP-Cron jobs work when you have a visitor, then this plugin should work for you. The plugin uses exactly the same code as WP Cron does, just in a different way, and with safeguards, a keep alive, logging available, etc.
The ‘background process’ is really a HTTP request that loops indefinitely until you press stop in the panel. I also use a lock file system to prevent multiple ‘processes’ starting, as well as provide a failsafe method of killing the process (if the lock file is gone when it wakes up, then it dies).

Doesn’t running a background process consume extra memory?

Yes, but only a small, fixed, amount of memory. During testing, I left the plugin running for a couple of weeks while logging memory usage each minute. There was no growth in memory usage (Iow, no memory leak) and a pretty small memory footprint (under 250KB).

Do you know if the “fake” visits will be detected by WP Stats/Google Analytics/etc?

The plugin calls wp-cron.php directly, so I doubt any stats programs will record these visits.

Does this allow you to create cron jobs, or does it just help them run?

It just helps them run when you expect them to (+/- 1 minute). Normally, WP Cron requires a visitor so the actual run time of a cron job can be hours after you scheduled it to run.

Will this works with WordPress MultiSite? And if so, can I turn certain double crons (like plugin update checks) off?

I haven’t done any testing with WordPress multisite yet. I created it for a project I was working on and spun it off into a standalone plugin. Unfortunately, I haven’t made anywhere near enough sales to justify much extra development effort at this stage, however I’m open to sponsorship to test and/or extend it.

Simple and works nicely. Thank you for making this free and for maintaining it.

I said “at the moment” since I posted a question to the plugin author. It says “no support” (which is odd) but I’m just trying to get this plugin to work and it seems to be functioning, but other indications show that the plugin “is not” working. So, at the moment, I need to give this plugin only a rating of one star since I’m anticipating no help from the author and the plugin appears to not be working. I’ve tried disabling all plugins .. but that didn’t help. If the author replies back and helps with this, I’ll certainly update my post and rating. I’m keeping my fingers crossed. It would be nice if this plugin worked.
