Return success message

try this

 ->withErrors('message', 'There was a failure while sending the message!');

@rin4ik You have not returned any messages. One note is that the user is not logged in.

Please use {, } because it makes your code a lot clearer!

if ($mail) {
    return redirect()
        ->back()
        ->with('success', 'Your message has been sent successfully!');
}

return redirect()
    ->back()
    ->withInput()
    ->with('error', 'There was a failure while sending the message!');

So this bit of code is not working for you? Do you get redirected back?

Install debugbar

As well as lots of useful information, it will show what is in session

@bobbybouwmann

I added {,} ... yes everything is working the message is being sent successfully and returns to page. Only the success or error message does not appear.

So it could be an issue with the view then, or even just css? (debugbar would confirm this)

view the html source in your browser and check for ypur messages

Well, when you use with it will be returned as a variable and not as a session variable! Instead you need to do this

return redirect()
    ->back()
    ->withInput()
    ->with('error', 'There was a failure while sending the message!');

@if (isset($error))
    <div class="col-sm-12">
        <div class="alert  alert-danger alert-dismissible fade show" role="alert">
          $error
                <button type="button" class="close" data-dismiss="alert" aria-label="Close">
                    <span aria-hidden="true">&times;</span>
                </button>
        </div>
    </div>
@endif

If you want to use a session you need to do something like this

session()->put('error', 'There was a failure while sending the message!');

return redirect()
    ->back()
    ->withInput();

Now you can access it like a session in your view

@if (session()->has('error'))
    {{ session('error') }}
@endif

Now I'm returning to mesangem, the problem is in the alert display

Thank you my friends for your attention and patience. I found the problem, it was in the alert css.

@bobbybouwmann It worked out right now I checked your code and removing the css appeared.

Thank you all!

No problem ;)

One last thing, if you can help. I have seen that now the message is not disappearing after refreshing the page.

Use session->flash instead of session->put. It will put it in the session only for the next request.

@Vilfago Thank you! Resolved.
