an li... if the tv exists

I’m creating a website for a client with products that have multiple template variables. I’d like to be able to pull those tv’s into an unordered list, so in the template I would have:

<ul>
<li>[*tv_1*]</li>
<li>[*tv_some_other*]</li>
</ul>

...But, right now if one of the products doesn’t have any info entered for the TV, I just end up with a bullet point. I would like to be able to just not have the li for that tv show up if it’s empty for that product. How would I go about doing that?

Thanks!!! You guys rock.

Try phx. If it is a product-listing with Ditto, phx is included and you can use phx directly.
Without ditto you need to install the plugin phx before you can use it.
Then try:

<ul>
     [*tv_1*:isnot=``:then=`<li>[*tv_1*]</li>`]
     [*tv_some_other:isnot=``:then=`<li>[*tv_some_other*]</li>`*]
</ul>

another option is to create a snippet ’imagelister’ for your list:

<?php

$tvnames = explode(',', $tvnames);
$output = '';

if (count($tvnames) > 0)
{
    $imagetvs = $modx->getTemplateVarOutput($tvnames);
    foreach ($tvnames as $tvname)
    {
        $image = $imagetvs[$tvname];
        if (!empty($image))
        {
            $output .= '<li>'.$image.'</li>';
        }
    }
}
return $output;

and call it:

<ul>
[!imagelister? &tvnames=`tv_1,tv_some_other`!]
</ul>
