Redirecting with sending Datas in laravel

问题

I tried following code: if the user's info to login is not correct redirect the user to the loin page again with the a message:

if (!$info_is_correct){
    $_SESSION['err_msg'] = 'your login info is not correct';
    return redirect('http://localhost:8000/user/login');
}

this is what I do in the login page(view) to echo the error msg:

    @isset($_SESSION['err_msg'])
        <div class="alert alert-danger mt-2" style="font-family:IRANSans;font-size:16px ;">
            <p>
                <strong>خطا !</strong>
                {{$_SESSION['err_msg']}}
                <?php unset($_SESSION['err_msg']) ?>

            </p>
        </div>
    @endisset

where is the problem? and What is the best way to send data to view with redirecting?

回答1:

Use the with() method:

return redirect('http://localhost:8000/user/login')->with('err_msg', 'your login info is not correct');

And if a view:

@if (session('err_msg'))
    <div>{{ session('err_msg') }}</div>
@endif

You can do like this to send your error messages with use inputs

return redirect('http://localhost:8000/user/login')->with('err_msg', 'Your error message')->withInput();

Source : Laravel Redirects, Laravel Validate

Note : You can also work with Error Messages like this

回答3:

Since you are using laravel the validations can be done by making use of validators and simply return

redirect()->back()->withErrors($validator)

and from the view you can have access to an $errors variable which will hold all the errors,

and you can loop through errors variable and print out the errors

from your login view

@if ($errors->any())
    <div class="alert alert-danger">
        <ul>
            @foreach ($errors->all() as $error)
                <li>{{ $error }}</li>
            @endforeach
        </ul>
    </div>
@endif

Set session value in laravel with session method, be sure to use because it is global and set session value for whole site.

Also remove http://localhost:8000 to work this route in both development and production.

if (!$info_is_correct){
    session('err_msg', 'your login info is not correct');
    return redirect('/user/login');
}

And get value form session as session('key')

{{session('err_msg')}}
