Action Scheduler


Action Scheduler is een schaalbare, traceerbare taak wachtrij voor het op de achtergrond verwerken van grote sets acties in WordPress. Het is speciaal ontworpen om verspreid te worden in WordPress plugins.

Action Scheduler werkt door het triggeren van een actie hook om op een bepaald moment in de toekomst uit te voeren. Elke hook kan worden gepland met unieke gegevens, zodat callbacks bewerkingen op die gegevens kunnen uitvoeren. De hook kan ook worden gepland om op één of meer momenten te worden uitgevoerd.

Zie het als een uitbreiding op do_action() die de mogelijkheid toevoegt om een hook te vertragen en te herhalen.

Battle-Tested Background Processing

Elke maand verwerkt Action Scheduler miljoenen betalingen voor Subscriptions , webhooks voor WooCommerce en e-mails en andere gebeurtenissen voor een reeks andere plugins.

Het is gezien op live sites waar wachtrijen van meer dan 50.000 opdrachten werden verwerkt en resource intensieve operaties, zoals het verwerken van betalingen en het aanmaken van orders, met een aanhoudende snelheid van meer dan 10.000 per uur werden uitgevoerd zonder de normale werking van de site negatief te beïnvloeden.

Dit is allemaal op infrastructuur en WordPress sites buiten de controle van de plugin auteur.

Als je plugin achtergrondverwerking nodig heeft, vooral van grote reeksen taken, kan Action Scheduler helpen.

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!
