Maths Captcha originally released to Supporters of the Project.
Hook which adds a Maths question to some of the forms on your site.

1.0.2
Deprecated tep_ functions fixed for later Phoenix Cart versions

This hook will allow you to easily create shortcode projects for easy use in info_pages.

For example, you can create a shortcode of:
[mycoolcode title="My Cool Project" products_id="123" button_class="btn-danger" text="This is an example"]

And then add a file:
includes/hooks/shop/siteWide/shortcodes/mycoolcode.php

An array of $shortcode['params'] will be passed to the mycoolcode.php file and you can code accordingly to replace the original:

[mycoolcode title="My Cool Project" products_id="123" button_class="btn-danger" text="This is an example"]

with whatever the params and your imagination can think of.

I am planning on building some cool modules that use this for integration, I thought I would share and see what others come up with.

Have Fun!
