error Class ‘JRequest’ not found in Joomla 4

Joomla’s latest update had made a lot of changes to its core classes. Joomla occupies 3.2% of the market share. This update is not just about new features; it also means bidding farewell to some old practices.

Among the alterations is the deprecation of the ‘jrequest’ class. While I was updating my website from Joomla 3 to Joomla 4, I faced this following error. This is how I could fix the error. Let’s first locate the areas in your code where we have used the ‘jrequest’ class. Look for lines like this:

Old Code

$data = JRequest::getVar('data');

In Joomla 4, the ‘jrequest‘ class is replaced with the ‘input‘ class. This new class will be the key to resolving the error.

New Updated Code

$jinput = JFactory::getApplication()->input;
$data = $jinput->get('data');

Make sure to replace all instances of the ‘jrequest’ class throughout your code, following the pattern shown above.

Check the Official Documentation

If you encounter any problems, refer to the official Joomla 4 migration guide for more detailed information on the update process.

Seek Expert Assistance if Needed

Don’t hesitate to seek professional help if you’re stuck. Joomla’s community forums or expert Joomla developers can provide assistance.

With these clear and practical steps, you’ll successfully resolve the “jrequest” class not found error in Joomla 4, ensuring your website or application continues to function seamlessly with the latest updates.
