Check if no child category exists

Hi,

I am generating a nested expand/collapse menu of parent and child categories. With my current setup, only the child categories have permlinks, and the parent category’s title simply shows/hides the children on click.

I now have a need to check if a parent category has any children or not. If no children exist, then apply a permlink to that parent category.

Here’s my code:

<ul id="menu">
<txp:category_list children="0" wraptag="" break="li">
	<h6 <txp:if_category name='<txp:category />'>class="expanded"<txp:else />class="collapsed"</txp:if_category>><txp:category title="1" /></h6>
	<txp:category_list parent='<txp:category />' exclude='<txp:category />' wraptag="ul" break="" class="">
		<li><txp:category title="1" link="1" section="product-catalogue" /></li>
	</txp:category_list>
</txp:category_list>
</ul>

Please help :)

<ul id="menu">
<txp:category_list children="0" wraptag="" break="li">
	<txp:variable name="has-children" value='<txp:category_list parent=''<txp:category />'' exclude=''<txp:category />''>yes</txp:category_list>' />
	<h6<txp:if_category name='<txp:category />'> class="expanded"<txp:else /> class="collapsed"</txp:if_category>>
		<txp:if_variable name="has-children" value=""><txp:category title="1" link="1" /><txp:else /><txp:category title="1" /></txp:if_variable>
	</h6>
	<txp:category_list parent='<txp:category />' exclude='<txp:category />' wraptag="ul" break="" class="">
		<li><txp:category title="1" link="1" section="product-catalogue" /></li>
	</txp:category_list>
</txp:category_list>
</ul>

Re: Check if no child category exists

For you speed freaks out there, here an improved version of the code. Reason:

etc wrote #293007:

yields an extra (and unnecessary) db query per category.
