Shorthand conditions for Laravel Blade

templates.php

<?php

/**
 * This is a sort of “inline”, more readable if-then-echo statement
 * for Blade in Laravel, mainly used for dynamically adding classes
 * or attributes to HTML elements.
 * 
 * The syntax is
 * 
 *  (( [classname] if [condition] ))
 * 
 * Do not put quotes around the class name. Parentheses around the condition are optional.
 * so for example:
 *  <a href="{{ Route::to('user') }}" class="userlink(( guest if !Auth::check() ))"> </a>
 * 
 * Will compile to
 * 
 *  <a href="<?php echo Route::to('user') ?>" class="userlink<?php if(!Auth::check()) echo ' guest'; ?>"> </a>
 * 
 * 
 * Put this somewhere before your view is loaded (I usually create
 * a file called app/templates.php to store all my Blade extensions
 * and require it from app/start/global.php, where the filters.php
 * file is loaded too)
