How to add a new module position in a Joomla! 1.5 template

Open your template file where you would like to place the module position

 Add the following code to the template file

<?php if ($this->countModules('customPosition')) : ?>
<div id="customPosition"  >
<jdoc:include type="modules" name="customPosition" style="xhtml"  />
</div>
<?php endif; ?>

NOTE: customPosition is the name/identifier for the new module position

Now you need to tell Joomla! which module positions are available within the template, to do this open the templateDetails.xml file within the root folder of your template and add the following code within the namespace

<positions>
   <position>customPosition</position>
</positions>

NOTE: You would probably only need to add customPosition to the template between the  tag
