Customization of Blade Directive in Laravel 5.7

There is a convenient feature for coding blade templates in Laravel’s view file. It is called ‘directive’. For example, @if and @endif.

What if I need a customized directive? How do I do that?

In my case, I have a long statement in the view file to test if the user is a administrator? I use @if to to do so in the first place. However, it requires the same function in many places and is little annoying to type many words. So I use custom directive to solve this problem and make the code looks more concise.

@if(auth()->check() && auth()->user()->isAdmin())
  <div>
    :
  </div>
@endif

Customization blade statement

Simple steps:

Just put the code in the boot() function of the AppServiceProvider.php. That’s it!

• app/Providers/AppServiceProvider.php
  (use if statement (laravel >= 5.5))

public function boot() {
  \Blade::if('isAdmin', function() {
     return auth()->check() && auth()->user()->isAdmin();
  });
}

Now, it looks more intuitive and concise!

@isAdmin
  <div>
    :
  </div>
@endisAdmin
