hello,
im trying to set up a custom filter on the internal field "created_on" in the Task module. The user should be able to select a month. I have trouble with this filter, as it doesnt get displayed.
i prepare the variables for the call of set_custom_filter, but whatever i user for $db_field, its not working. i tried ":Created_on", "Created_on", "created_on"... no effects at all.
$this->rb->set_custom_filter(
$db_field,
array(
'type'=>'select',
'label'=>$this->t('time period'),
'args'=>$args,
'trans'=>$trans
)
);
Am i doing it wrong or is it not possible to filter by internal fields? Do i need to "work arroud"?
Greetings, Christof
