For example, I have a function and can I somehow display this message that the body should not be empty, display it on the screen?
public function store(Request $request){
$comment = new Comment;
$comment->body = $request->get('comment_body');
if(empty($comment->body)){
return back()->with('Body should not be empty! ');
}else{
$comment->user()->associate($request->user());
$post = Article::find($request->get('article_id'));
$post->comment()->save($comment);
return back();
}
}
You can redirect using flashed data
Redirecting to a new URL and flashing data to the session are usually done at the same time. Typically, this is done after successfully performing an action when you flash a success message to the session. For convenience, you may create a RedirectResponse instance and flash data to the session in a single, fluent method chain:
So your controller should look like this:
if(empty($comment->body)){
return back()->with('error', 'Body should not be empty! ');
And in your view you can display the error like this:
@if (session('error'))
<div class="alert alert-success">
{{ session('error') }}
</div>
@endif
But i strongly recommend you to read the validation section of the laravel documentation. You can achieve better results if you create a request or use the validate method
