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?
控制器:
public function viewRegistrationForm()
{
$usersType = UsersType::all();
return View::make('search')->with('usersType',$usersType);
}
视图:
{{ $usersType or '' }}
it shows the error :
Undefined variable: usersType (View: C:\xampp\htdocs\clubhub\app\views\search.blade.php)
{{ $usersType or '' }}可以正常工作.这里的问题是foreach循环:
@foreach( $usersType as $type )
<input type="checkbox" class='default-checkbox'> <span>{{ $type->type }}</span>
@endforeach
我建议你把这个放进@if():
@if(isset($usersType))
@foreach( $usersType as $type )
<input type="checkbox" class='default-checkbox'> <span>{{ $type->type }}</span>
@endforeach
@endif
你也可以使用@forelse.简单又容易.
@forelse ($users as $user)
<li>{{ $user->name }}</li>
@empty
<p>No users</p>
@endforelse
