Just this morning I tried to apply this tip!
Unfortunately without success.
Thanks Stef

I think I’ve spotted an error here. Nesting <txp:older /> (or <txp:newer />) inside a <txp:older></txp:older> (or <txp:newer></txp:newer>) will give invalid markup, as the container creates a link (<a>) around the contained code, which already has a link.

Also, if I’m not wrong, the “duplicated” if_variable for creating opening and closing div tags for #navigation could be converted in just one if_variable at top (well, just below the line were the variable has been created) that will output just all or nothing.

]]> Jonathan Stubbs Comment on Display navigation if newer or older values exist by Stuart 1 1 Sat, 22 May 10 13:50:50 +0000 Does this work better?:-

<txp:if_article_list>
<txp:variable name="has_np" value='<txp:older /><txp:newer />' />

<txp:if_variable name="has_np" value="">
<txp:else />
<div id="navigation"> <!-- start entry navigation -->

<div class="nav-links"><txp:older><txp:text item="prev" /></txp:older></div>

<div class="nav-links"><txp:newer><txp:text item="next" /></txp:newer></div>

</div> <!-- end entry navigation -->
</txp:if_variable>
</txp:if_article_list>

though you can still end up with an empty “nav-links” div if one or other of the Txp tags is empty.

<txp:if_article_list>
<txp:variable name="has_np" value='<txp:older /><txp:newer />' />

<txp:if_variable name="has_np" value="">
<txp:else />
<div id="navigation"> <!-- start entry navigation -->

<txp:variable name="has_np" value='<txp:older />' />
<txp:if_variable name="has_np" value="">
<txp:else />
<div class="nav-links"><txp:older><txp:text item="prev" /></txp:older></div>
</txp:if_variable>

<txp:variable name="has_np" value='<txp:newer />' />
<txp:if_variable name="has_np" value="">
<txp:else />
<div class="nav-links"><txp:newer><txp:text item="next" /></txp:newer></div>
</txp:if_variable>

</div> <!-- end entry navigation -->
</txp:if_variable>
</txp:if_article_list>

and yes, I probably should have come up with that the first time but it is much easier to see when the code is there in front of you. ;)

<txp:variable name="has_np" value='<txp:older /><txp:newer />' />
	<txp:if_variable name="has_np" value="">
		<txp:else /><!-- entry navigation -->
		<div id="navigation">

	<txp:variable name="older" value='<txp:older />' />
	<txp:if_variable name="older" value="">
		<txp:else />
   		<div class="nav-links">&#8592; <txp:older><txp:text item="older" /></txp:older></div>
	</txp:if_variable>

	<txp:variable name="newer" value='<txp:newer />' />
	<txp:if_variable name="newer" value="">
		<txp:else />
   		<div class="nav-links"><txp:newer><txp:text item="newer" /></txp:newer> &#8594;</div>
