Title: Cronjob Scheduler Author: chrispage1 Published: May 16, 2014 Last modified: May 26, 2020 --- Search plugins This plugin **hasn’t been tested with the latest 3 major releases of WordPress**. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress. ![](https://s.w.org/plugins/geopattern-icon/cronjob-scheduler.svg) # Cronjob Scheduler By [chrispage1](https://profiles.wordpress.org/chrispage1/) [Download](https://downloads.wordpress.org/plugin/cronjob-scheduler.1.40.1.zip) * [Details](https://wordpress.org/plugins/cronjob-scheduler/#description) * [Reviews](https://wordpress.org/plugins/cronjob-scheduler/#reviews) * [Installation](https://wordpress.org/plugins/cronjob-scheduler/#installation) * [Development](https://wordpress.org/plugins/cronjob-scheduler/#developers) [Support](https://wordpress.org/support/plugin/cronjob-scheduler/) ## Description #### Cronjob Scheduler Cronjob Scheduler allows you to create custom WordPress tasks that are automatically triggered on a schedule you define. Cronjob Scheduler does not overwrite WordPress’s existing scheduling functionality, which it and plugins use for a number of internal tasks. Instead, it simply replaces the standard WordPress mechanism which triggers them with a more reliable one from your operating system. In addition, it helps improve your site speed by making the server handle recurring tasks, rather than unsuspecting visitors… The motivation behind building this plugin was out of frustration with other similar plugins that claim to do the same thing. Cronjob Scheduler allows you to run frequent tasks reliably and timely without anyone having to visit your site at all. All you need is at least 1 action and a Unix Crontab schedule! #### About This plugin was designed and built by Motocom. It is designed to make easy work of creating and managing custom cron jobs. If this plugin has been helpful for you, then please donate to keep our WordPress plugin projects running! ## Screenshots [⌊Cronjob Scheduler Interface⌉⌊Cronjob Scheduler Interface⌉[ Cronjob Scheduler Interface [⌊Creating new schedules is easy⌉⌊Creating new schedules is easy⌉[ Creating new schedules is easy [⌊The process of creating a new scheduled task⌉⌊The process of creating a new scheduled task⌉[ The process of creating a new scheduled task ## Installation 1. Upload `cronjob-scheduler` folder to the `/wp-content/plugins/` directory 2. Activate the plugin through the `Plugins` menu in WordPress 3. You will now be able to manage your Cronjob schedule under `Settings > Cronjob Scheduler` 4. Once on this page, follow the plugins instructions to ensure everything is setup and ready to go 5. Instructions, and a template for creating new actions can be found in the plugin admin. #### Running your cron tasks Most shared providers offer a crontab manager, or you can speak to your shared hosting provider about setting up our cron job. If you manage the server, you can setup your cron using the crontab service. Make sure that wget is installed befor doing this. #### Creating Custom Action Example ``` function my_cronjob_action () { // code to execute on cron run } add_action('my_cronjob_action', 'my_cronjob_action'); ``` ## FAQ ### Can I create my own custom schedules? That’s the whole idea of the plugin, you setup your schedules and the tasks you want to run and the plugin will handle the rest! ### How do I create a task to run? Just create a new function in your theme files (or somewhere else you will remember) and create an action with the same name. ### Can I run an event at any time? Sure, just go to the Cronjob Scheduler interface and hit the `Run` button against the task. ## Reviews ![](https://secure.gravatar.com/avatar/5af1a367e702d21390f1bc7e43613bc810d09d5580b65da3c716c39133206f1d? s=60&d=retro&r=g) ### 󠀁[Great plugin and great support](https://wordpress.org/support/topic/great-plugin-and-great-support-499/)󠁿 [xjamesb](https://profiles.wordpress.org/xjamesb/) May 20, 2020 1 reply This plugin simply replaces the adhoc triggering of your scheduled tasks with a trigger delivered by your host operating system. This increases reliability. There are no downsides. It also makes it easy to create your own cron job. I had some questions about how it worked and the developer gave me great support. ![](https://secure.gravatar.com/avatar/a66589387202c4ad825a4c8ee7236f4f48ccaf45236377640e0d7f31150120d4? s=60&d=retro&r=g) ### 󠀁[Working well and fast support from the developer](https://wordpress.org/support/topic/working-well-and-fast-support-from-the-developer/)󠁿 [jdoe87165](https://profiles.wordpress.org/jdoe87165/) June 20, 2019 1 reply This plugin was recommended for another plugin, Projectopia.

The UI is stellar, and functions as advertised, however, without the ability to control the exact time of execution, it is unusable for most applications. ![](https://secure.gravatar.com/avatar/935a0dec9e848fe631fb79eec701213b37505de71d4561dd4e4c2b0b8483bf06? s=60&d=retro&r=g) ### 󠀁[Excellent and Useful Plugin for Developers](https://wordpress.org/support/topic/excellent-and-useful-plugin-for-developers/)󠁿 [grcplaybook](https://profiles.wordpress.org/grcplaybook/) June 5, 2017 This is a fantastic plugin. I use it in conjunction with the “SLM Woo Addon” and“ Software License Manager” plugins to send emails to users whose license is about to expire. I have no connection to Chris Page or Motocom and therefore have no hesitation in recommending you make a donation for this plugin (see link at bottom right of Cronjob Scheduler). If you think this plugin is not working I suggest you do the following: 1. Install the “Code Snippets” plugin by Shea Bunge and add the following snippet: // Test cronjob created by Chris Page add_action(‘cronjob_test’, function(){ file_put_contents(WP_CONTENT_DIR . ‘/.test.txt’, “\nHit at ” . date(‘Ymd-His’), FILE_APPEND); }); 2. In the Cronjob Scheduler, which is in Settings, create an Action and name it “cronjob_test” with a run time of once every minute. 3. Create a file,. test.txt (including the dot at the start of the filename), in your wp-content folder. 4. Start the snippet and check if information is being written to .test.txt: e.g. Hit at 20170601-110444 5. If the file is empty, note the information in “Plugin Details” (bottom right of Cronjob Scheduler). In particular that you need a cronjob that runs every minute. If you don’t know how to set up a cronjob, contact your ISP. 6. Remember to stop the Code Snippets cronjob if “Hit at …” is being written to the .test.txt file. ![](https://secure.gravatar.com/avatar/55482c1a86ed369c95c7067b27864eb40465dead3dcf0c978caaa976178be9e0? s=60&d=retro&r=g) ### 󠀁[Not working](https://wordpress.org/support/topic/not-working-1311/)󠁿 [maximote](https://profiles.wordpress.org/maximote/) October 27, 2016 1 reply It does not work on the latest version of wp. ![](https://secure.gravatar.com/avatar/78fd6d216eecbf886225f72696a7d575e0ba8cf4eb364f0daa00087ea8fd5fd5? s=60&d=retro&r=g) ### 󠀁[Perfect plugin](https://wordpress.org/support/topic/perfect-plugin-284/)󠁿 [Hesham Zebida](https://profiles.wordpress.org/hishaman/) September 3, 2016 I was in need of this while debugging some the WordPress cron.
