Action Scheduler

تفصیل

Action Scheduler is a scalable, traceable job queue for background processing large sets of actions in WordPress. It’s specially designed to be distributed in WordPress plugins.

Action Scheduler works by triggering an action hook to run at some time in the future. Each hook can be scheduled with unique data, to allow callbacks to perform operations on that data. The hook can also be scheduled to run on one or more occassions.

Think of it like an extension to do_action() which adds the ability to delay and repeat a hook.

Battle-Tested Background Processing

Every month, Action Scheduler processes millions of payments for Subscriptions, webhooks for WooCommerce, as well as emails and other events for a range of other plugins.

It’s been seen on live sites processing queues in excess of 50,000 jobs and doing resource intensive operations, like processing payments and creating orders, at a sustained rate of over 10,000 / hour without negatively impacting normal site operations.

This is all on infrastructure and WordPress sites outside the control of the plugin author.

If your plugin needs background processing, especially of large sets of tasks, Action Scheduler can help.

What this plugin/library adds to WordPress is incredibly powerful. It’s asynchronous execution of actions gives developers incredible possibilities. The fact that plugin developers have the option to integrate this plugin/library into their own plugins is fantastic. Keep up the good work!

Only tested it, I didnt like it, and now it wont leave. Manually removing tables – crashes my site. Sucking the life out of my server. I have to ask support for how to get rid of it. Horrible Horrible

This plugin is a classical malware:1) it acts hidden: it integrates in Wordpress core, don’t identificate itself for site owner, don’t allow any management of it’s activity or control for site owner. 2) It secretly and non-stop (every minute) allocates all server resources displacing all useful processes like processing user’s requests and all others too. It slow down site in times. From my experience “server response time” decreased from 7-8s to 1,2s just as I started to limit this malware, but I still can’t stop or remove it completely (there is no woocommerce on my site, but I believe that it were the result would be more impressive). 3) It acts as extension to Wordpress’s wp_cron service. All that it does can be done under pure wp_cron but not hidden and without slowing down site. So, it’s crear to understand that if some other plugin use Scheduled Actions it does it only to hide something from site owner eyes or/and slow down site (probably to upsale pro version that acts without Scheduled Actions. 4) There is no way how to completely stop neither uninstall it neither remove it’s actions neither it’s wp_cron task. 5) It’s impossible just to short circle some functions in it to stop it’s working – it’s code made the way that it break site down if someone try to stop it. I have found the way to limit it’s activity but can’t stop it completely. 6) All question to developers regarding this behavior return with answer like “it runs as we wish, keep enjoying slow down your site” or buy our other plugins or employ us to find why your site is slow down. Explanations about clear difference with Scheduled Actions working as they with and limited they just ignore. I strictly advice plugin developer run a mile of this malware otherwise site owners have to remove already your plugins accusing already you in the fatal slow of their sites and probably with criminal charge (at least in EU).

Developers refuse to support their own plugin. I have no use for something that does not work, and something the developers will not support. Cannot and will not recommend to anyone… sadly will not make much of a difference because it’s in use in every site that utilizes WooCommerce, but, whatever…

Look, I’m fine with having to do some coding. After all, I want to write my own php code to be called every five minutes or so. But you have to tell me WHERE to put the calls. I’ve installed your service via plugin, and your usage page (actionscheduler [dot] org [slash] usage) tells me exactly nothing about where I need to make these API calls. Is it function.php in my home WP directory? Can I make these calls from my own self-made directory? Tell me!
