Be part of JetBrains PHPverse 2026 on June 9 – a free online event bringing PHP devs worldwide together.
I have currently this in my AppServiceProvider.php file:
public function boot()
{
Blade::if('user', function () {
$user = Auth::user();
return auth()->user() && $user->role_id === 1;
});
Blade::if('editor', function () {
$user = Auth::user();
return auth()->user() && $user->role_id === 2;
});
Blade::if('manager', function () {
$user = Auth::user();
return auth()->user() && $user->role_id === 3;
});
Blade::if('admin', function () {
$user = Auth::user();
return auth()->user() && $user->role_id === 4;
});
}
How would you optimize this code? It seems very repetitious to me. But I am not sure how Blade:: works so I am not sure how to limit the db calls and stuff.
Thanks for any help in advance.
You call auth twice? Also add a helper method on the user model
Blade::if('user', function () {
$user = Auth::user();
return $user && $user->isUser(); //or ->hasRole('user')
});
But none of them should do any database calls. User is already loaded
@Sinnbeck Thanks, yeah you are right I will use $user that I already get from Auth::user(). Thank you again.
@Sinnbeck One more question, could I put $user = Auth::user(); outside of Blade and then call it via $user inside of each Blade? Something like this:
public function boot()
{
$user = Auth::user();
Blade::if('user', function () {
return $user && $user->role_id === 1;
});
Blade::if('editor', function () {
return $user && $user->role_id === 2;
});
...
}
or like this?
public function boot()
{
$user = Auth::user();
Blade::if('user', function ($user) {
return $user && $user->role_id === 1;
});
Blade::if('editor', function ($user) {
return $user && $user->role_id === 2;
});
...
}
Will this work?
@vedoj you need to pass it into the scope
Blade::if('user', function () use ($user) {
return $user && $user->role_id === 1;
});
@Sinnbeck Yeah, use, of course, so, which code is more efficient and will do less calls if all four blade guards will be present in some view at once?
Code A:
public function boot()
{
Blade::if('user', function () {
$user = Auth::user();
return $user && $user->role_id === 1;
});
Blade::if('editor', function () {
$user = Auth::user();
return $user && $user->role_id === 2;
});
Blade::if('manager', function () {
$user = Auth::user();
return $user && $user->role_id === 3;
});
Blade::if('admin', function () {
$user = Auth::user();
return $user && $user->role_id === 4;
});
}
or
Code B:
public function boot()
{
$user = Auth::user();
Blade::if('user', function () use ($user) {
return $user && $user->role_id === 1;
});
Blade::if('editor', function () use ($user) {
return $user && $user->role_id === 2;
});
Blade::if('manager', function () use ($user) {
return $user && $user->role_id === 3;
});
Blade::if('admin', function () use ($user) {
return $user && $user->role_id === 4;
});
}
@vedoj both do 0 database calls, so I don't think you will find any difference between the two
@Sinnbeck That would be great, because the code B will be easier to maintain. Thanks again.
Auth::user() and auth()->user() are the same.
So you can simplify like this for each if statement.
Blade::if('user', function () {
$user = Auth::user();
return $user && $user->role_id === 1;
});
If you really want each different if statement to use @user, @editor, ... it's pretty good.
Instead you can add pass variable to the if statement.
https://laravel.com/docs/9.x/blade#custom-if-statements
And if you have variables like Role::ADMIN, you could for example use it in a unique if statement.
@role(Role::ADMIN)
...
@endrole
@vincent15000 Thanks.
Just like in my previous question about middleware performance, which you answered as well ;), I would ask you about guards the same.
Will having 20 or 100 Blade if guards slow down the performance of my website? Or only the actual guards I use on each page matter when it comes to performance?
@vedoj For this new question, you can create a new post.
