Located in File: /AkActionView/helpers/capture_helper.php
Capture lets you extract parts of code into instance variables which can be used in other points of the template or even layout file.
== Capturing a block into an instance variable
<?php $capture_helper->begin (); ?> [some html...] <?php $script = $capture_helper->end (); ?>
== Add javascript to header using content_for
$capture_helper->content_for("name"); is a wrapper for capture which will store the fragment in a instance variable similar to $content_for_layout.

Summary:Method Detail

Method begin (line 74)

Capture allows you to extract a part of the template into an instance variable. You can use this instance variable anywhere in your templates and even in your layout.

Parameters
- $var_name:
Info
Method content_for (line 115)
void content_for( $name)
Content_for will store the given block in an instance variable for later use in another template or in the layout.
The name of the instance variable is content_for_<name> to stay consistent with $content_for_layout which is used by ActionView's layouts
Example:
<?php $capture_helper->content_for('header'); ?> alert('hello world'); <?php $capture_helper->end(); ?>
You can use $content_for_header anywhere in your templates.
NOTE: Beware that content_for is ignored in caches. So you shouldn't use it for elements that are going to be fragment cached.
