We’re going to look at five Laravel Blade directives you can use to simplify your templates, and learn about some convenient directives that make solving specific problems a cinch! If you’re new to the framework, these tips will help you discover the excellent features of Blade, Laravel’s templating engine.
Let’s get started.
1. Check if the user is authenticated
When checking if the user is authenticated, you could check if the user isn’t null:
@if(auth()->user()) // The user is authenticated. @endif
However, Laravel ships with a custom Blade directive that provides the same functionality more cleanly:
@auth // The user is authenticated. @endauth
2. Check if the user is a guest
The inverse of the authentication, we can check if the user is not authenticated using the
guest() method on the
@if(auth()->guest()) // The user is not authenticated. @endif
But Laravel also provides a
@guest // The user is not authenticated. @endguest
We can also combine those two directives using the
@guest // The user is not authenticated. @else // The user is authenticated. @endguest
3. Include the first view if it exists or includes the second if it doesn’t
Building a website with multiple themes might require including a file if it exists or including another one if it doesn’t, you can easily achieve this with simple blade conditions:
@if(view()->exists('first-view-name')) @include('first-view-name') @else @include('second-view-name') @endif
There is a shorter and a much cleaner directive for including the first found template:
4. Include a view based on a condition
Conditionally including a view based on a condition is useful when you only want to add content based on logic like an authenticated user.
You could write this using an
@if($post->hasComments()) @include('posts.comments') @endif
We can more cleanly include a view based on a condition with the
@includeWhen directive with one line:
5. Include a view if it exists
If you have custom themes system or you dynamically create your Blade views, then checking if the file exists a mandatory thing to do.
exists method on the view helper will do the trick:
@if(view()->exists('view-name')) @include('view-name') @endif
But it turns out there is a simple way of handling this using the
includeIf Blade directive:
You can learn about these and other useful tricks in the official Blade documentation for improving your frontend templating in a Laravel project.
