How to Add this simple php code in a website form?

I have this php code from a Advert rotator and i need to post in a webform in the WP admin to place it the website. I do not want to do changes in the template i want to use the form. The form is FINE with adsense code and other php code but this code does not work. Do i need to add some filling to it?

<?php if(function_exists('mba_display_zone')) mba_display_zone(6);?>

PHP:

 

First make sure that the function mba_display_zone exists.

Then put that code wherever on which page you want the ad to appear.

 

Yes it does, but that will not answer my question i need the code in a iframt or div or something since i am putting it in a form not inside a php page.

 

There are a few plugins for integrating PHP code to worpdress. You can search google with "php on wordpress" without the quotes.

 

Thats not the issue here, i already have a plug in and that is causing the problem. I just want to know how to use normal DIV or JAVA code to put this code into a form.

 

<?php
  echo '<div>';
  if(function_exists('mba_display_zone')) mba_display_zone(6);
  echo '</div>';
?>

PHP:

 

Sorry that did not work it just show the code. What does work is like this

<a href="http://www.woothemes.com/woomember/go?r=55088&i=l43&redirect=mydomain"><img src="http://woothemes.com/ads/468x60b.jpg" /></a>

PHP:

or normal adsense code

I asked the woo theme already but the do not know either.
