Hi, I have a component already done and i need to add a new filter,
So i created the select on the plural form with the on change Joomla.submit
the id and name of this filter is filter_approved

I go to fork/models on prepareQuery
i do
echo $this->getState('filter_approved'); or
echo $this->getState('filter.approved');

NOTE : I also added to $this->set('filter_vars', array( on the construct

I tried with the other filters and thy work fine
and i get nothing ! probably this variable is filtered somewhere !
Can u help me please?

Can you please copy/paste your prepareQuery function?

Did you also create a new filter in the builder?
