Laravel Blade check user role

Question

In laravel Blade templating we can exclude some parts of HTML with this code:

        @if (Auth::user())
            <li><a href="{{ url('/home') }}">Mein Profil</a></li>
            <li><a href="{{ url('/admin') }}">Admin</a></li>
        @else
            <li><a href="{{ url('/home') }}">Mein Profil</a></li>
        @endif

If user is authenticated then show home and admin links and if user is not authenticated then show only home link.

My question is how to make a check here if user is admin?

I have default login system from laravel and i just added one more column in table users -> ('admin') with tinyint value 1 and in this video https://www.youtube.com/watch?v=tbNKRr97uVs i found the code for checking if user is admin

 if (!Auth::guest() && Auth::user()->admin )

and it works in AdminMiddleware.php but it doesn't work in blade. How to make this working??

Try to logout and login again, it may be because of you added column after loggedin and that may not be loaded ins Auth::user session. also add your dump response of this echo "<pre>"; print_r(Auth::user()); die() in your question, So we can see that admin column is coming or not – Flaxseed

Are you getting any error? – Reconstruct

I made a check route and with this it prints out check OK Route::get('check', function() { echo 'check OK'; }); and with this Route::get('check', function() { print_r(Auth::user()); }); prints nothing.....not even an error! – Rihana

Sorry guys but it works now.....i think i needed just to reset the server :( my bad – Rihana

Answer 1

I find such a long winded, check if logged in, check role, being added all around my blade files to distracting. You may consider adding a custom blade directive. Add something like this to AppServiceProvider boot() function

Blade::if('admin', function () {            
    return auth()?->user()?->admin === true;
});

in blade just use

@admin
<p>Only admin sees this</p>
@endadmin

            @if (!Auth::guest() && Auth::user()->admin)
                <li><a href="{{ url('/home') }}">Mein Profil</a></li>
                <li><a href="{{ url('/admin') }}">Admin</a></li>
            @else
                <li><a href="{{ url('/home') }}">Mein Profil</a></li>
            @endif      

this works just to be clear (just add one more column tinyint 'admin' in user table and set to 1)

You can use the method> HasRole

You can call this from artisan tinker from command line, just to see it before writing code:

php artisan tinker

Check if the user with id 1 has role 'user';

User::find(1)->hasRole('user');

Check if the user with id 1 has role 'admin';

User::find(1)->hasRole('admin');

The same way while coding for example in app.blade template:

@if (Auth::user()->hasRole('admin'))
        <li><a href="{{ url('/home') }}">Main Profile</a></li>
        <li><a href="{{ url('/admin') }}">Admin</a></li>
 @else
        <li><a href="{{ url('/home') }}">Main Profile</a></li>
 @endif

The method hasRoles comes from the package spatie/laravel-permission

composer.json: "spatie/laravel-permission": "^3.16"

full path of the class: vendor\spatie\laravel-permission\src\Traits\HasRoles.php

where does this method come from? ->hasRole() this seems not to be part of Laravel – Rihana

The method hasRole($roles, string $guard = null): bool --> is part of the vendor "spatie/laravel-permission" package. Full path: \vendor\spatie\laravel-permission\src\Traits\HasRoles.php – Sensual
