No Images in a Category
I’m trying to figure out a way to output some default text if no images are found for a particular image category. Here is the relevant part of my page code:
<txp:article section="artists" pgonly="1" />
<txp:asy_wondertag>
<txp:wet_for_each_image category="<txp:custom_field name="artistname" />">
<txp:upm_image form="thumb_click" image_id="{id}" />
</txp:wet_for_each_image>
</txp:asy_wondertag>
What I’d like to do is output something like “There are no images for this artist” if the above code has no output. I tried using the chh_if_data plugin, but it doesn’t seem to appreciate all the tags within tags stuff in this case, or the asy_wondertags maybe.
Any suggestions? Thanks!

Re: No Images in a Category
Where did you place the chh_if_data tags?

Re: No Images in a Category
Els: I tried placing them just OUTSIDE the asy_wondertag tags and I also tried placing them just INSIDE the asy_wondertag tags.

Re: No Images in a Category
Is that custom_field used for anything else other than image category connection?

Re: No Images in a Category
chh_if_data doesn’t work if it is wrapped around more than one txp tag. Does it work if you wrap it around the upm_image tag?

Re: No Images in a Category
Els: Thanks for working with me on this. That doesn’t seem to work either. I tried this, but the text output did not appear:
<txp:article section="artists" pgonly="1" />
<txp:asy_wondertag>
<txp:wet_for_each_image category="<txp:custom_field name="artistname" />">
<txp:chh_if_data>
<txp:upm_image form="thumb_click" image_id="{id}" />
<txp:else />
<p>no images</p>
</txp:chh_if_data>
</txp:wet_for_each_image>
</txp:asy_wondertag>
Any other thoughts?

Re: No Images in a Category
Hmm.. that must be because of the image_id="{id}". I may have found a (sort of) workaround, but I need to know a couple of things first.
What does this code of yours display exactly? A list of thumbnails for a category that has the same name as the custom field ‘artistname’?
And what is the url of such a page?

Re: No Images in a Category
Els: Yes, you’re exactly right about what the code displays: it’s a list of thumbnails for a category that has the same name as the custom field ‘artistname’. Here is a URL on my testing server for one of those pages:

Re: No Images in a Category
Well, I’ve done some testing, and I would have found a workaround if this was about articles, but apparently chh_if_data doesn’t work with image tags. So I can’t help you.
But I’m sure that it can be done with php, so all you have to do is wait for a proper coder to come by and tell you how :)

Re: No Images in a Category
Thanks very much for giving it a try Els. I appreciate it. I’ll keep working on it and post something back here if I get something. If anybody else has any ideas, let me know!

Re: No Images in a Category
thebombsite: I’m sorry I missed your question. The custom field is ONLY used for the image category connection.
