Laravel刀片请求方法

Question

Recently I started learning Laravel by following the Laravel From Scratch cast(https://laracasts.com/series/laravel-5-from-scratch).

Right now I'm trying to add additional functionality to the registration form(starting with error feedback) and I already ran into a problem.

Is there a (native) way to check wether the form has been submitted or not? I tried to use:

{{ Request::method() }}

But even after pressing Register on the default scaffold generated by running the command php artisan make:auth it returns GET while the action of the form is POST and it triggers a route with a POST Request type.

The reason for all of this is that I want to add a CSS class to a element based on the following requirements.

if form is submitted
   if $errors->has('name') //is there an error for name(example)
      add 'has-error' class
   else
      add 'has-success' class
   endif
endif

Does anybody know a solution for it?

Answer 1

I think you want to achieve this:

if( old('name') ){ // name has been submitted
  if( $errors->first('name') ){ // there is at least an error on it
    // add error class
  }else{ // has been submitted without errors
    // add valid class
  }
}

That in a input field is something like this:

<input name="name" class="validate{{ old('name') ? ( $errors->first('name') ? ' invalid'  : ' valid') : '' }}" type="text" value="{{ old('name') }}">
