question?

I‘m reading Laravel Blade‘s templating docs and I can‘t find how I can assign variables inside a template for use later in the template. I can‘t do

{{ $old_section = "whatever" }}

I see that I can do

<?php $old_section = "whatever"; ?>

answer

You can put it in your application/start.php or if you will have more things like this put it in a separate file and include it there. Laravel is very loose in this way, you could even put thin a controller. The only thing you have to do these extends before the view is rendered.

<?php/** * <code> * {? $old_section = "whatever" ?} * </code> */Blade::extend(function($value) {    return preg_replace(‘/\{\?(.+)\?\}/‘, ‘<?php ${1} ?>‘, $value);});

In laravel-4, you can use the template comment syntax to define/set variables.

Comment syntax is {{-- anything here is comment --}} and it is rendered by blade engine as

<?php /* anything here is comment */ ?>

so with little trick we can use it to define variables, for example

{{-- */$i=0;/* --}}

will be rendered by bladeas

<?php /* */$i=0;/* */ ?>

how to add variable in blade template?
