I'm reading the Laravel Blade documentation and I can't figure out how to assign variables inside a template for use later. I can't do {{ $old_section = "whatever" }}
because that will echo "whatever" and I don't want that.
I understand that I can do <?php $old_section = "whatever"; ?>
, but that's not elegant.
Is there a better, elegant way to do that in a Blade template?
LARAVEL 5.5 AND UP
The @php blade directive no longer accepts inline tags. Instead, use the full form of the directive:
@php
$i = 1
@endphp
LARAVEL 5.2 AND UP
You can just use:
@php ($i = 1)
Or you can use it in a block statement:
@php
$i = 1
@endphp
LARAVEL 5
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.
