Hi there,

I'm trying to output a list of pages using wayfinder. Each page has a template variable that is a link. If this is set I want to output the name of the page as a link to the url specified in the tv. If the tv is not set, I just want to output the name of the page.

What I want to know is how do I use snippets to output the relevant html?

So far I have it working so far that it displays the following row template:
```
<li>
<a href="[[processTV? &myId=`[[+id]]` &myTV=`assemblyInstructions` ]]" title="[[+wf.title]]" [[+wf.attributes]]>[[+wf.linktext]]</a>
[[+wf.wrapper]]
</li>
```
Using this snippet:
```
<?php
$doc = $modx->getObject('modResource', $myId);
return $doc->getTVValue($myTV);
```
Obviously this makes everything a link, but some of the hrefs are blank.

I want to change it so that if the tv is not set it just outputs the linktitle with no anchor.
Please help! I've been trying all morning with no success!

Set a placeholder of the processed TV:

<?php
$doc = $modx->getObject('modResource', $myId);
$value = $doc->getTVValue($myTV);
$modx->toPlaceholder('myhref',$value);
return '';

And then in your template, you could check with the "notempty" Output modifier, if you have a value:

[[processTV? &myId=`[[+id]]` &myTV=`assemblyInstructions` ]]
[[+myhref:notempty=`<a href="[[+myhref]]" title="[[+wf.title]]" [[+wf.attributes]]>[[+wf.linktext]]</a>`:else=`<a title="[[+wf.title]]" [[+wf.attributes]]>[[+wf.linktext]]</a>`]]

Not tested but if i remember right, this should be possible..
