Blade if(isset) is not working Laravel

Question

Hi I am trying to check the variable is already set or not using blade version. But the raw php is working but the blade version is not. Any help?

controller:

public function viewRegistrationForm() {     $usersType = UsersType::all();     return View::make('search')->with('usersType',$usersType); } 

view:

{{ $usersType or '' }} 

it shows the error :

Undefined variable: usersType (View: C:\xampp\htdocs\clubhub\app\views\search.blade.php)

Answer 1

{{ $usersType or '' }} is working fine. The problem here is your foreach loop:

@foreach( $usersType as $type )     <input type="checkbox" class='default-checkbox'> <span>{{ $type->type }}</span> &nbsp;  @endforeach 

I suggest you put this in an @if():

@if(isset($usersType))     @foreach( $usersType as $type )         <input type="checkbox" class='default-checkbox'> <span>{{ $type->type }}</span> &nbsp;      @endforeach @endif 

You can also use @forelse. Simple and easy.

@forelse ($users as $user)    <li>{{ $user->name }}</li> @empty    <p>No users</p> @endforelse 

Answer 2

@isset($usersType)   // $usersType is defined and is not null... @endisset 

For a detailed explanation refer documentation:

In addition to the conditional directives already discussed, the @isset and @empty directives may be used as convenient shortcuts for their respective PHP functions
