when calling "JRequest::get('FilterForm')" result is empty

Question

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?

Answer 1

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).
