JREQUEST-GETVAR-001

JRequest::getVar()

JRequest::getVar() and the whole JRequest API

Joomla removed the global request object. There is no class alias and the compatibility plugin does not bring JRequest back. This dies on the first Joomla 4 boot.

JRequest::getVar() → $app->getInput()->get('id')

Dies at Joomla 3 → 4J3: Works nativelyJ4: Removed — fatalJ6: Removed — fatalBC plugin: no — already dead on J4Patch possible — review itJoomla API

Replace this code

Swap JRequest::getVar() for $app->getInput()->get('id').

Joomla 3

Remove or stop calling this

$id = JRequest::getVar('id');
$cid = JRequest::getInt('cid');

Joomla 4 / 6

Use this instead

use Joomla\CMS\Factory;

$app = Factory::getApplication();
$input = $app->getInput();
$id = $input->get('id', 0, 'INT');

How to fix it

  1. 1Get the application, then $app->getInput().
  2. 2Replace getVar/getInt/getCmd with Input::get() and a filter (INT, CMD, STRING).
  3. 3Search the whole ZIP for JRequest — every call is a Joomla 4 blocker.
