Adding Google AdSense ads is easy in Textpattern. Following the same procedure as the previous tip on creating re-usable headers and footers, we simply use a form to output the Google AdSense ads.
Create a new form called “google_textads” and set type to “misc”
This form should contain the Google AdSense code, something like the code below.
<div class="google">
<script type="text/javascript"><!--
google_ad_client = "your publisher id here";
google_ad_slot = "7410366493";
google_ad_width = 120;
google_ad_height = 90;
//-->
</script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>
</div>
Output the form in your page where you want the ads to appear
<div id="textads">
<txp:output_form form="google_textads" />
</div>
