Part 29 - Authentication User Experience [How to Build a Blog with Laravel 5 Series]

We have our authentication working now, and in this video we learn how to modify our user experience based on whether or not the current user is logged in or logged out.

If the user is logged in we will show our dropdown menu and if they are logged out we will display a simple button to login.

We use blade @if statements and our new Auth::check() helper to see if the user is logged in. If they are logged in then our Auth::check() will return true and execute the if statement, otherwise it will execute the else statement.

We will put the HTML needed for our dropdown in the first if statement clause, and we will put the button to login in the else clause.

To finish up our tutorial we want to make a customary friendly notification when the user is logged in. We will have the logged in menu say "Hello Name". To do this, we take advantage of our second helper Auth::user() and then we just access the property for each column name in the user database table.

Coming Up:
Forgot my Password functionality in our authentication tutorial.

I am wondering how many people did all this before they go to the video? I did. It's a good way to test how you do it and how the teacher does it...and it was identical.

for newer laravel you can use @guest on blade instead of Auth::check as an in-built if then else with auth as a conditional

[hamidelabassi]

to give the login button the same styling, you can use:
<li>
<a href="{{ route('auth.login') }}">Login</a>
</li>

Hey first things first: Great Job! Thank you for the amazing tutorial, I learned so much in the past days! Next steps are to apply my new knowledge for my own little project. However I a missing one small feature: How to allow to edit/delete logged in users only their own blog posts?

[maheralmasalati]

Mr.alex when i add if statment in navbar the output in index page was that

FatalErrorException in Grammar.php line 151:
Maximum function nesting level of '100' reached, aborting!

[RubendeMan]

Hi Alex! First, thank you very much for these helpful tutorials! But I have a question about showing the name in the view via the model, because in the 'What the hell is MVC' you talked about views, and that they must NOT communicate directly to models, like you do with Auth::user? Isn't Auth a model?

[mohamedmamdouh]

For those who has error " Maximum function nesting level of '100' reached, aborting! "
I found the solution =>
open bootstrap /autoload and add this line at the end
ini_set('xdebug.max_nesting_level', 120);

Thank you.

What could be interesting but, probably beyond the scope of this tutorial. Allow registered users to edit / delete ONLY their posts.

Hi there i've found a little bit of a snag but the auth:check() creates a nesting error when placed it in a partial like the nav .. this is a known error on the laracast forum but would you happen to know how to fix this or maybe of another way to check if a user is logged in? thanks
