Hi ;
I am trying to build a freelancer script with cakephp . I made
categories and projects. One project can have more than one category
so I set the relationship of categories and projects to habtm . I hope
everything is right until here because I spend really a big time for
that . Anyway . Now the problem is I want to limit the maximum
category checkbox a user can check . How can I validate that data .
Some ideas :
I can get the count of the $this->data['categories']
['categories'] in the projects controller before saving data . But the
thing is I have to set the validation error and stop the form from
submitting . I cannot do this in a controller does anyone knows how ?
Or can I validate project categories in project model ?
