Laravel Middleware在提交表单之前执行操作

Question

I am just creating a random app to check if the user is eligible for voting or not. I am using middleware to check if age is less than 18 then redirect to /age/validate. But the problem is the middleware is performing action before form submission. Please help.

Form::

{!! Form::open(['action'=>'AgeController@store', 'method'=>'POST']) !!}
    {!! Form::number('age', null) !!}
    {!! Form::submit('Check') !!}
{!! Form::close() !!}

Middleware::

public function handle($request, Closure $next)
{
    if($request->age <= 18){
        return redirect()->route('noteligble');
    }

    return $next($request);
}

Route:

Route::get('/age/validate', function(){
    echo 'You are not eligible to vote';
})->name('noteligble');

Route::resource('checkage', 'AgeController')->middleware('agechecker');

Please Help me how i can make middleware work only after form submission.

Answer 1

A middleware is executed before every request. You're assigning the middleware to the whole resource and therefore to the route which displays the form.

The solution

Assign the middleware only to the store method in the controller. Remove the ->middleware('agechecker') method call from your routes file and add assign that in your controller constructor like this:

public function __construct()
{
    $this->middleware('agechecker')
         ->only(['store']);
}
