escape
Prevents any code written in between the tags from being treated as executable.
Example
<p>If we find an account registered for [%escape%][@email@][%/escape%], instructions have been sent to this email address.</p>
Result
If <h1>BIG FONT</h1>
was entered into the email field, it would display on the page as:
<h1>BIG FONT</h1>
The source code of the page would contain:
<h1>BIG FONT</h1>
Usage
Commonly used to prevent sections with user input from accidentally/purposefully interfering with the rendering of the page. Similar to the nohtml
function but more secure as it renders everything inside as text, rather than only removing the html tags.
