Custom Laravel Blade Directive gives error when if statement is being used

Question

I have this opiece of code in the boot of my RoleServiceProvider:

public function boot()
{
    Blade::directive('role', function ($role) {

        $hasRole = User::find(Auth::id())->hasRole($role);

        return "<?php if ( $hasRole  ) : ?>";
    });

    Blade::directive('endrole', function ($role) {
       return "<?php endif; ?>";
    });
}

The var $hasRole is holding the status: true/false, now i my blade:

@role('user-manager')
    hello
@endrole

Looks OK to me, but it is giving me this error:

Facade\Ignition\Exceptions\ViewException syntax error, unexpected ')' (View: C:\wamp64\www\laravel6\packages\users\management\src\View\overview.blade.php)

For some reason I don't know as the code looks fine to me.. Some suggestions?

if you remove @role('user-manager') hello @endrole will the error gone? — Dilip Hirapara

have you added added RoleServiceProvider in $providers array in config/app.php file? — Sehdev

Yes, when having a simple text in it, it is working. And when do dd($hasRole) it is returning true/false — Robert Dam

I believe this directive is written incorrectly. Take a look at the generated view inside storage/framework/views (clear this directory first and then go to the page where you use this directive). You echo $hasRole but the view doesnt know that variable. — Flame

Try to use if directive instead.

Blade::if('role', function ($role) {
    return User::find(Auth::id())->hasRole($role);
});

In Blade:

@role('user-manager')
  hello
@endrole

Also, you can get a user object straight away from Auth like this:

return Auth::user()->hasRole($role);

Does this: return Auth::user()->hasRole($role); also work when using it inside a package and a custom User model?
