Check unless condition in custom if blade directive in Laravel
Blade::if() method already comes with the following directives in order to check various conditions in blade template files.
@custom- Checks positive if condition
@elsecustom- Checks elseif condition
@endcustom- endif condition
So, for instance, if you want to check conditions on the
env variables in the blade file, you could do like so.
@env('local') // The application is in the local environment... @elseenv('testing') // The application is in the testing environment... @else // The application is not in the local or testing environment... @endenv
Now, if you want to check if something should render only when the application in the “production” mode, you could do like so.
@env('production') @else // The application is not in the production environment... @endenv
As you can see, here in this case, we’re using an empty
if condition which is quite an overkill.

This PR, #30492, registers an additional
@unlesscustom directive (a negative if condition) to deal with such kind of a situation.
So, using this, the previous example would simplified to the following.
@unlessenv('production') // The application is not in the production environment... @endenv
This looks much cleaner than the previous approach. isn’t it?
You can start using this feature starting from Laravel version 6.x.
