From the documentation I use this part to store a large chunk of data

if (empty($families)) {
  $cache = Factory::getCache();
  $families = $cache->call( array( 'JFormFieldFamily', 'getFamilyList' ) );

Working perfectly on my Joomla 3.9.6, however my extension in Joomla 4 throws this

Warning: call_user_func_array() expects parameter 1 to be a valid callback,
class 'Joomla\CMS\Cache\Cache' does not have a method 'call' in
site\libraries\src\Cache\CacheController.php on line 74

Looking into the documentation for Joomla\CMS\Cache\Cache

$families = $cache->call( array( 'JFormFieldFamily', 'getFamilyList' ) );


$families = $cache->get( array( 'JFormFieldFamily', 'getFamilyList' ) );

and works properly on Joomla 3.9/4.

Do I need to use $cache->store() method?

The call method has been marked as removed for Joomla 4.0, as it's simply a wrapper for get().

You don't need to manually store the cache as this is done within the get() method:


  • Thanks for the clarification, perhaps this should be reported to the Joomla dev team.

    @thednp Apparently @deprecated 4.0 means it will be removed in 4.0. Rather bad terminology in my opinion but oh well.
