When calling the method $this->filterForm = JRequest::getVar('FilterForm');, I get an empty result. But checking the com_banners component on the same system shows a result. What can I do to get it working?

This is the way to retrieve an input:

$jinput = JFactory::getApplication()->input;
$this->filterForm = $jinput->get('FilterForm', 'default_value', 'filter');

TIP: Take into account that if your don't specify a default_value, it will return null when no value is detected. If your don't specify a filter, it will apply a strict filter, CMD, for commands (It allows a-z, 0-9, underscore, dot, dash. It also removes leading dots from result).

  • The result is still NULL (when I remove the 'filter' and the 'default_value'). I think, I have something completly wrong. Thats why I get no result.

  • @DreiBaer - In which case the issue will be with a different part of your code.

  • WHat do you mean with "case"? I have implemented it Component-File -> Controller (with constructor) -> View.
