问题 Forgive me if this has been answered before, I couldn't find an answer where the validation depended on the aggregate of inline forms. Little background: I'm doing a site for an insurance broker which has 'Policies' and a 'Total Commission' of that policy.

问题 I've just started using laravel and I'm working on validating a textarea in one of my forms. The textarea is for the users bio and so I only want to allow letters, numbers, spaces and the following characters: , . ? ; : ' " - () ! / @ $ This is what I have $validator = Validator::make(Input::all(), array('bio' => array('regex:[a-zA-Z0-9 ,\.\?;:\'"-\(\)!/@\$]') ) ); I've been searching and trying a lot to get it to work but I just can't figure it out. Any help would be much appreciated. Thanks
