Symfony Slots

How to use Slots in Symfony.

Symfony Slots are ways to set simple data in one template, and have it displayed in another. It’s helpful if, for example, you want to set the Title in the layout from a controller actions view. Rather than ramble on about Symfony Slots, I’ll blast through how Slots are used in Symfony and leave you to figure the rest out:

First, this is how to retrieve a slot you have set (I will go over setting them in a moment):

$x = get_slot('slot_name'); echo $x;

Or you can just output the slot:

include_slot('slot_name');

Thats useful, for example, in your global template (layout).

You might want to set the slot – useful in a page-specific view, for example:

slot('title','The title');

Or you can do it like this, so you don’t have to explain to Mr. front-end developer why a single quote is breaking everything:

<?php slot('extra'); ?>
<meta foobarfoo />
<?php end_slot(); ?>

Finally, you might want to check if a slot exists:

if(has_slot('extra')):
  include_slot('extra');
endif;

So there you go. Bish, bash, bosh.
