问题 I want to extend the Form validation class to support array form elements like described here for L3 in L4.

问题 I have made a laravel package which contains a route, it is a special route that catches a large number of possible urls. I don't want my route to take precedence over other packages or routes declared in the main application. How can I ensure that my route is the last route declared? 回答1: Routes are evaluated in the order that they are listed in routes.php. Simply making sure this route is the last one in the array should do it. update I believe you could just register the route in the App:

问题 I'm writing a Laravel 4 app that has a users table with the usual contact info. In my users model, my validation for the email specifies 'email'=>'required|email|unique:users', which works fine when registering new users. My question is how to handle the user edit form-- when the form is submitted, I'd like for the unique email constraint to only be fired if it's not the same as the old email-- otherwise you can't save your profile, since the email (your email) is already inuse.

问题 any comments included in a blade are causing apache to crash when I try to load said page. The project I'm working on uses blade comments for notes and everything, so removing them isn't an option. I'm using xampp on windows. Anyone have any ideas? 回答1: You must ensure that your blade opening and closing tags are correct and don't use the @ character in the comment: {-- Should work --} {-- @will crash --} {-- that @doesn't work either --} 来源： https://stackoverflow.com/questions/28174162/blade

For example: $users = Subject::select(DB::raw('subjects.*, count(user_subjects.id) as total_users')) ->join('user_subjects', 'user_subjects.subject_id', '=', 'subjects.id') ->whereNull('user_subjects.deleted_at') ->groupBy('subjects.id') ->orderBy('subjects.updated_at', 'desc') ->paginate(25); Produced select subjects.*, count(user_subjects.id) as total_users from `subjects` inner join `user_subjects` on `user
