Adding Captcha to a new page?

[ctroyp]

I have been searching for quite some time on how to add captcha functionality to a new (custom) page.

 

In the TPL file, I have added:

{if $capatacha}<p align=center>{$LANG.imagecheck}<br><img src="includes/verifyimage.php" align="absmiddle"> <input type="text" name="code" size="10" maxlength="5"></p>{/if}

and the section does not display. So, I tried it without the if statement to test it:

<p align=center>{$LANG.imagecheck}<br><img src="includes/verifyimage.php" align="absmiddle"> <input type="text" name="code" size="10" maxlength="5"></p>

The section does show, but it does not work.

 

I am assuming that I need to test for the entered text after submitting the form on the new page, but how do I do that?

 

What am I missing here?
