title: Laravel select element in Form not inserting value
body: <p>I modified the register controller AND the user table to have a role attribute as a string:</p>
  
  <pre><code>Schema::table('users', function (Blueprint $table) {
          $table-&gt;string('role')-&gt;nullable()-&gt;index();
      });
  </code></pre>
  
  <p>and i have created an enums.php in config folder like this:</p>
  
  <pre><code>return [
  'role_types' =&gt; [
      'ADMIN' =&gt; "Admin",
      'TEACHER' =&gt; "Teacher",
      'STUDENT' =&gt; "Student",
  ]];
  </code></pre>
  
  <p>on the register user view (which is scaffold by default with bootstrap)
  i made select box to accommodate the selection:</p>
  
  <pre><code>&lt;select class="form-control" id="role" name='role'&gt;
             @foreach (Config::get('enums.role_types') as $role)
                      &lt;option value="{{ $role }}"&gt;{{$role}}&lt;/option&gt;
             @endforeach
  &lt;/select&gt;
  </code></pre>
  
  <p>But up on registering the user, the value is NULL.. what am i doing wrong ?</p>
