I have User HABTM Language, and i want to ensure during a User add /
edit they choose a minimum of one language, upto a maximum of 3. In
the user model, for $validate I've tried:
'Language' => array(
'multiple' => array(
'rule' => array('multiple', array('min' => 1,
'max' => 3)),
'message' => 'Please select a tleast 1 langiage
upto a maximum of
3'
),
),
And in the add/edit form i have $this->Form->input('Language'); which
doesn't actually validate.
It does work if I use language_id instead of Language (both in the
form on the add/edit pages and in the model $validate) - but then it
doesn't save any data in the join table.
Any advice on getting the above to validate, or save habtm when using
"_id".
