Hey guys -

I used the search but didn't find a solution, sorry!

I have a blog on my website in which I want to include preview Images for blog posts.

-> I created a TV: PreviewImage, Input: Image, Output: Image.
-> Selecting the image in the blog post works just fine

-> Want to output it in my blog post list (Chunk "blogPost") kinda like this (unformatted for now):

<img src="[[*PreviewImage]]" />
<div class="ditto_summaryPost">
  <h3><a href="[[~[[+id]]]]" title="[[+pagetitle]]">[[+pagetitle]]</a></h3>
  <br />
  [[+introtext:empty=`[[+content]]`]]
  <p class="ditto_link"><a href="[[~[[+id]]]]" class="readmore">Weiterlesen</a></p>
  <br /><br />
</div>

In my html output, it shows the <img /> tag, but the src="" ist empty - what did I do wrong?
Shouldn't it output <img src="http://example.com/assets/images/example.jpg" /> ?

Thanks a lot! [ed. note: c.kurtzmann last edited this post 15 years, 1 month ago.]

<img src="" />

Here the MODx tags got lost (it's like that in this forum...)
Try to make bold the first [ of the tag: <img src="[[*PreviewImage]]" />
But that does not answer your question, of course...
I think the Output Type should be URL, not image. [ed. note: ottogal last edited this post 15 years, 1 month ago.]

use

<img src="[[+PreviewImage]]" />

in your chunk

use
<img src="[[+PreviewImage]]" />
in your chunk

Unfortunately, even that doesn't work.

I tried

<img src="[[+PreviewImage]]" />

and

<img src="[[*PreviewImage]]" />

I don't get it - all the other TVs and Chunks work just fine!

Which snippet are you using to output your list... getResources? (wasn't sure why you had Ditto classes in there

)

For getResources, tv placeholders need to be prefixed like this:

[[+tv.PreviewImage]]

Awesome! Thank you Lucas, that did it!
I'm new to ModX and used the default Chunk for the blog posts listing...
