How to Set Variables in a Laravel Blade Template

by

LARAVEL 5.5 AND UP

Use the full form of the blade directive:

@php
$i = 1
@endphp

LARAVEL 5.2 – 5.4

You can use the inline tags:

@php ($i = 1)

Or you can use it in a block statement:

@php
$i = 1
@endphp

ADD A ‘DEFINE’ TAG

If you want to use custom tags and use a @define instead of @php, extend Blade like this:

/*
|--------------------------------------------------------------------------
| Extend blade so we can define a variable
| <code>
| @define $variable = "whatever"
| </code>
|--------------------------------------------------------------------------
*/

\Blade::extend(function($value) {
    return preg_replace('/\@define(.+)/', '<?php ${1}; ?>', $value);
});

Then do one of the following:

Quick solution: If you are lazy, just put the code in the boot() function of the AppServiceProvider.php.

Nicer solution:
Create an own service provider. See https://stackoverflow.com/a/28641054/2169147 on how to extend blade in Laravel 5. It’s a bit more work this way, but a good exercise on how to use Providers 🙂

LARAVEL 4

You can just put the above code on the bottom of app/start/global.php (or any other place if you feel that is better).

After the above changes, you can use:

@define $i = 1

to define a variable.
