Hi,
I'm trying change column with lang keys in DB when is not filled then column should be null, but it isn't.
It is not filled:
In database when I save node:
I have this code:
/**
* [Node] Format form values from add/edit form for save
*
* @param array $values Values from the form
* @return array
*/
public function formatFormValues($values)
{
if (!$values['axenserverlist_debug_text']) {
$values["axenserverlist_debug_text"] = NULL;
}
return $values;
}
but it doesn't work for me, because always return string with comma.
How can I change the code when no one has typed anything in input, then returns null in DB?
