How to check dropdown list in Laravel PHP?

Question

Situation:

In the models I have user.php, which handles all the checks regarding adding a user to the website.

This is (part of) the code:

public static $add_rules = array(
   'last_name'             => 'required',
   'first_name'            => 'required',
   'email'                 => 'required|unique:users,email',
   'username'              => 'required|alpha_num|min: 5|unique:users,username',
   'password'              => 'required|min: 4|same:password_confirmation',
   'password_confirmation' => 'required',
   'user_role'             => 'required|not_in:-- Choose User Type --'
);

user_role is the id of the dropdown list, see here:

<select name="user_type_id" class="form-control" id="user_role">
<option value="0">-- Choose User Type --</option>
@if(Session::get("user_type") == "superuser")
     {
     @foreach($user_types as $ut)
         <option value="{{$ut['id']}}">
             {{ ucwords($ut["user_type"]) }}
         </option>
     @endforeach
     }
@else{
     <option value="Regular">Regular</option>
}@endif
</select>

Basically, what happens is that the drop-down list is populated with user types, whatever they are. But he always has the first "option" -- Choose User Type --.

Problem:

The problem is that the user can go with this option and add the user. I have javascript code that blocks this and displays an error message in a popup window, but it is ugly and inconsistent with the rest of the website error messages.
