I am trying to get a TV to output an image,in the properties fields I selected the images and on the document page under the template variable tab I can see the image no problem, however in the chunk which is being called from a template in get resources I have added this call [[*showroomimg]] which as far as I can see this is the call for TV’s in Revo however no image is output.

Can anyone tell me if this look right.

Many thanks

Check out your page source - are you sure the TV isn’t outputting? Did you wrap the TV in an img tag, i.e.:

<img src="[[*showroomimg]]" alt="Show Room" />

The image TV only outputs the path to the resource.

MODx creates a full image tag for image TVs, but only if you have the TV’s output type set to image rather than default. The down side is that all images using that TV will get the same size, caption, alt value, etc. I’d recommend leaving the output set to default and build the tag yourself as goonz suggests, using separate TVs for the other attributes.

OK understand leaving the output at default and I have now changed it back that and wrap it inside what i need. I still have the issue of nothing being output by the TV right now, I have left the input type as image and on the child page where I have added the image using the TV i can see the image there ok but I cant see it when its called via getresources via the chuck in the template.

Thanks for the advice however its so useful.

Many thanks

Ian

quick edit here this is whats in my chunk:

<h2>[[+pagetitle]]</h2>
[[*showroomimg]]
<img src="[[*showroomimg]]" alt="Show Room" />
<p>
[[+introtext]] - <a class="readmore" href="[[~[[+id]]]]" title="[[+pagetitle]]">More Information ..</a>
</p>
<hr />

Its all very experimental for now but I just cant get that damn TV to work

I have now tried every method on the TV to do with input type and output type, the only thing that nakes a differance is if I change the output to rich text then I do indeed get a text box appear.

If I add in just the TV it’s not outout at all but if included inside the image tag the resulting html is this

<h2>test 2</h2>
no output no img output 2nd
<img src="[*showroom]]" alt="Show Room">now outside of img tag

If anyone know a way to find why the template vairable call wont work or another day to acheive this please let ne know I am guessing that is the correct call for a TV in Revo.

Thanks again

If the tag is in a Tpl chunk used by getResources, you need to use a placeholder tag:

[[+TvName]]

You’ll also need to add the TV-related parameters to the getResources tag: &tvPrefix, &includeTVs, etc.

Bob you might have just seen the missing details I have experimented with them placeholders in the call but still no luck, I cant find any documentation or working examples of getResources so I am just running with the similar method to ditto, so here’s everything I have.

The parent page has this call

[[getResources? &parents=`49` &tpl=`showroom`]]

The showroom chunk tpl now has this

<h2>[[+pagetitle]]</h2
[[*showroom]]

<p>
[[+introtext]] - <a class="readmore" href="[[~[[+id]]]]" title="[[+pagetitle]]">More Information ..</a>
</p>
<hr />

The template variable is called showroom has in input of image and an output of default.

The html output is the following

<h2>test 2</h2>
bike2.jpeg

<p>
 - <a class="readmore" href="index.php?id=54" title="test 2">More Information ..</a>
</p>
<hr>
<h2>test 1</h2>

bike2.jpeg

<p>
 - <a class="readmore" href="index.php?id=53" title="test 1">More Information ..</a>
</p>
<hr>

On that html the TV outputs bike2.jpeg on both pages but one of them should be bike1.jpg it looks like I am missing some other bits to make this work.

Any more help would be great thanks for everything so far.

Make it [[+showroom]] and add these to your getResources snippet tag:

&tvPrefix=`` &includeTVs=`1`

Damn still no luck.
I made the tag this

[[getResources? &parents=`49` &tpl=`showroom` &tvPrefix=``  &includeTVs=`1`]]

and in the chunk tpl i changed from [[*showroom]] to [[+showroom]]which resulted in no output. If I left the tag as [[+showroom]] outputs bike2.jpeg as in previous post.

For info I got the TV tag syntax from here http://rtfm.modx.com//display/revolution20/Tag+Syntax

Is there anything else left to try I wonder.

Thanks again for you patience.

Cheers

Ian

[[+tv.showroom]]

<p>
[[+introtext]] - <a class="readmore" href="[[~[[+id]]]]" title="[[+pagetitle]]">More Information ..</a>
</p>
<hr />
