Joomla Developer's Tips and Tricks

A few months ago, I have implemented pagination support in the K2 Content module for one of my clients.
It was implemented using Ajax technology upon the client request, but I will use jQuery (client side) pagination in this tutorial, leaving the Ajax pagination to next tutorial, let's go on...

Learn how easily to improve the performance of K2 with many extra fields created, you will notice the performance boost immediately after applying this hack...

How to setup the relationship between K2 user groups and extra field groups?
In the item.php, lines 15 to 19, you will find this array:
$efACL = array(
"3" => array("1", "2", "3"),
// Administrator
"4" => array("1","2"),
// Manager
"5" => array("1")
// User
);
As you can see, the keys of this array are K2 user groups ID 3, 4 and 5
And the value of each element is an array of extra field groups that can be seen by the users belonging
to the K2 user group.
For example “3”=> array(“1”, “2”, “3”) means that the users belonging to the K2 user group with ID =
3, which is the administrator group, can see the extra fields belonging to extra field groups with ID =1,
2, 3
Then, I added this condition && in_array($extraField->group, $canSee) in the IF statement which
checks for the extra field value before displaying it.
