Let button disappear when certain role is authenticated-CodePudding

I have two different tables where two different kind of users are stored.

The first are Portalusers, the second are employees.

Now I have an overview page of all posts, where Portalusers should be able to use a filter button for a department.

Employees should be able to use it aswell, IF their role IS NOT "FBL".

So I tried it with this code:

@if(auth()->user()->Rolle != 'FBL')
                <div >
                    <select name="abteilung" id="abteilung" >

                        <option selected="true" disabled="false">Abteilung</option>
                        @foreach($abteilungs as $abteilung)
                            <option value="{{ $abteilung->abteilung_name }}">{{ $abteilung->abteilung_name }}</option>
                        @endforeach
                        <option value="alle">Alle Abteilungen</option>
                    </select>
                </div>
                @endif

But when no-one is authenticated, so a guest is using the page I get an error Attempt to read property "Rolle" on null - which makes sense since no-one is authenticated.

But I also tried putting this before the @if:

@auth('web')
   @auth('portal')
      @auth('guest')

I have two guards, the one is the default laravel guard and the second one is my custom portalguard for portal users.

Is there any way I can make this work, so that the button is available when guests, portal users and employees which don't have the 'Rolle = FBL`, but disappears when someone with this specific role is logged in?

CodePudding user response：

You need to check if user is logged in before trying to access the user object.

To have it visible for guests and users with Rolle not as FBL, use this:

@if( ! auth()->check() || auth()->user()->Rolle != 'FBL')

I think, in your case, the best solution is:

1: Check if the user is logged in.

2: Check the role but instead of writing too much "ifs" I would do it like this (following your code)

//In your folder providers->AppServiceProvider.php -> method "boot"

    public function boot()
        {
            Blade::if('notfbl', function (User $user) { // you name it as you want I named it "notfbl", the parameter is the logged user
                return $user->id == auth()->user()->role_id != 1; // Here I assumed that the id of the FBL role is 1, you adjust it
            });
        }

// In your blade file you can use the "@notfbl($user)" in every part you need and also create more

        @auth // Everything inside "@auth" will be shown ONLY if the user is authenticated. If you want to do something for unauthenticated users you should write your html/code inside the "@guest @endguest" tags
            @notfbl($user) // It will be shown ONLY for users with role different to FBL
                <div >
                    <select name="abteilung" id="abteilung" >
                        <option selected="true" disabled="false">Abteilung</option>
                            @foreach($abteilungs as $abteilung)
                                <option value="{{ $abteilung->abteilung_name }}">{{ $abteilung->abteilung_name }}</option>
                            @endforeach
                        <option value="alle">Alle Abteilungen</option>
                    </select>
                </div>
            @endnotfbl
        @endauth

You need to use nested if statement i.e

// check if user is a guests, portal users or employees

if user == guest 

{

// write the code here for what guest should see

}

// so user is not guest

else 

{

// check if user is employee or portal user

    if user == employee

     {

     // write the code here for what employee should see

     }

     // user is not employee so user is portal user

     else

     {
    
      // write the code here for what portal use should see
     
     }
}
