The incredible possibilities offered by the Scheduled Tasks in Joomla

This presentation was / will be made at


Since version 4.1 (and so also in 5.x series) Joomla introduced a very interesting new feature called Scheduled Tasks.

Even though it has been present for more than two years, everytime I exchange with other Joomlers I realize that the majority has overlooked the power of this feature.

So the goal of this article is to shed some light on the possibilities at the hand of different examples / usecases:

  • some are native Plugins, ready to be used within Joomla
  • some are third-party Plugins, typically open source and available for free on Github
  • and of course the whole idea is that you can also create your own, in order to meet your specific needs

2 Other sources about the Task Scheduler

Quite luckily different people have already produced interesting content about the Task Scheduler.

So let me start by thanking and referencing them:

3 Scheduled Tasks - native Plugins

Go to your backend > System > Scheduled Tasks.

Click on the New button and see what is already natively available in J5:

  • Delete ActionLogs - Task
    Delete Action logs after days
  • Expiration of privacy consents
    Manage the expiration of privacy consents
  • Rotate Logs
    Periodically rotates log files.
  • Task - Session Data Purge
    Task Plugin that purges expired data and metadata depending on the session handler set in Global Configuration.
  • Joomla! Update Notification
    This task periodically checks for the availability of new Joomla! versions. When one is found it will send you an email, reminding you to update. You can customise the email
  • Image Size Check
    Check images, resize if larger than allowed. Attention: The original file will be overwritten!
  • GET Request
    Make GET requests to a server. Supports a custom timeout and authorization headers.
  • Toggle Offline
    Toggles the site’s status on each run.
  • Set Site Online
    Sets site status to online on each run.
  • Set Site Offline
    Sets site status to offline on each run.
  • Global Check-in
    Check in checked out items.

3.1 My favourite ones

My favourite ones are

3.1.1 Global Check-in

Gosh, how many times end-users called me in the last ten years because they were editing from the front-end but some Articles were “checked out” by “accident”, preventing them from opening them. Every time I would have to go to the back-end to “check-in” all Items.

Now I can automate this action every night at 3PM for example

3.1.2 Image Size Check

In many cases you want to have a maximum width or height for images in a given Folder. But even if you make your end-users aware of the importance or resizing (in order to have a better performance for the visitors but also to have smaller backups etc) still people “forget” to resize their images.

Now I can for given Folders automatically resize the images (for example I set a maximum width of 600 pixels for all images in the Newsletter folder)

3.1.3 Get request

For some of my websites, I need to trigger some synchronization thanks to a script which is accessible on a given URL. The Get request does exactly that…

4 Scheduled Tasks - third-party Plugins

4.1 Check-in all your Content in J4

As mentioned above, in Joomla 5 there is a Native Plugin to check-in all your Content. But what is your website is still running J4?

4.2 Auto-delete files

What about auto-deleting files older than a certain timeframe in a given folder only (and not its subfolders)

4.3 Change different Parameters of Articles automatically

What about being able to move Articles to other Categories in function of a certain date (or do similar things)

4.3.1 Kick Manage Article

A Task Scheduler to move articles from some Category to another Category when older than X days, based on the following dates:

  • created
  • modified
  • published
  • unpublished

Free - by KickTemp


4.3.2 CCC Timewarp

With this plugin, you can

  • move your Articles to a different Category depending on a certain Date
  • change the publication Status
  • adjust the Access Level

This is particularly useful if you use Joomla Articles to display Events, but also, for example, to make your news only available to a closed circle for x days and only make them public after some time.

NB: on top of the usual Types of Dates, you can also use a Custom Field of Type Date in your conditions, which is handy.

4.4 Reset Hits

For a given project where I needed to display “the most popular Films of the month”, I wanted to reset the number of Hits on the 1st day of every month.

In the Configuration you can choose to reset Hits for any of the following:

  • Articles
  • Tags
  • Categories

4.5 Synchronize my Custom Fields with some external Web Service

Yet for another project I needed to synchronize the value of 20 Custom Fields for 300 Articles with the latest data coming from some external Web Service.

Let’s take a practical example: is a kind of Directory of all Social Services and Associations in Brussels. You can access the details of each organization:

On the Joomla website there are hundreds of articles having Custom Fields for the Address, Phone number etc.

So the idea was to automate a daily synchronization between the external source and our website so that the end users would not spend hours every month checking whether some information were outdated since last time…

4.10 Feeding Articles from an external API

It reads an external API (a kind of Job Board) and feeds Joomla Articles of a given Category.

Official description: API interface for Apicodo Dorfapp. Task plugin to import the data time-controlled via the APICODO API. A category must be selected in the plugin to which the data records can be transferred. With each new request, all data records in the category are deleted and rewritten.

4.12 Migrate user profiles to custom fields

This “Scheduled Tasks” plugin migrates the data from the Joomla user profile to Custom Fields. Manually, hourly, according to your specifications.

Free by Kicktemp

4.13 Scheduled Tasks provided directly by some Extensions

As mentioned in the Sources, some extensions provide their own Task Schedulers. Examples:

5 Scheduled Tasks - create your own… and share it!

As you can see from the above-mentioned examples, the sky is the limit: for every need you can invent your own Scheduled Task.

This would be a nice topic for (yet) another article in the Joomla Community Magazine in the coming months: develop different nice usecases for Scheduled Tasks like:

  • connect your website with Zapier or other similar services
  • modify some Custom Field value based on some conditions
  • reset the password of (some) users every n months
  • do some database work (optimizing, …)
  • check and notify for updates
  • check for system modifications (PHP version, execution time, …)
  • interact with your newsletter extension
  • interact with your e-commerce extension (abandoned carts, …)
  • send Push Notifications (OneSignal, …)
  • send SMS (Twillio, …)

So please share your ideas/suggestions of Scheduled Tasks!

And if you already wrote one, please share the link so that everybody can enjoy…

Have fun and enjoy the power of Joomla! ❤️💙🧡💚
