Confused by txp:images tag
I’ve got a form:
<txp:article>
<txp:images><txp:image width="0" height="0" /></txp:images>
<txp:body />
</txp:article>and for each article, the following happens:
- if the article has image IDs in the “Article image” field, those images are displayed with that article
- if the “Article image” field is blank, all images in the database are displayed with that article
So, two questions:
- if the
<txp:images>tag is in article context mode, why is it reverting to “all images in the database”, just because an article has no image associated? - how can I output a list of articles, that may or may not have images associated, using standard tags?
Apologies if I’m missing the obvious … it’s been a long week.
P.S. auto_detect="article" doesn’t help either.

Re: Confused by txp:images tag
Like I said, it’s been long week …
<txp:article_image width="0" height="0" />… does the job.
But if I was using <txp:image_info>, which can only be used inside <txp:images>, – the above questions still stand.

Short answer: because it does :-)
Long answer: originally it did behave in the ‘correct’ (imho) way, but it was inconsistent with all the other ‘list’ tags which behave in this, somewhat erroneous, manner. Thus it was changed before release.
how can I output a list of articles, that may or may not have images associated, using standard tags?
Wrap the images tag in <txp:if_article_image> ?

Thanks for the reply Stef.

Oh dear, two steps forward, one step back … thank goodness <txp:article> doesn’t behave in this manner!
Wrap the images tag in
<txp:if_article_image>?
Or turn <txp:article_image> into a container tag?
So the default position of auto_detect="article" is actually auto_detect="article or baboom!" as well?

Re: Confused by txp:images tag
So, if I understand correctly, there is no way (with native txp tags) to output photos from the article_image field for each article IF they are are assigned to a specific image category?
I was hoping the code below would work, but it only repeats all of the site’s images with the “homeshow” category for each article (using Txp 4.5.1):
<txp:article_custom section="art" limit="999" sort="rand()">
<txp:images category="homeshow" auto_detect="article" break="" sort="rand()">
<p>
<a href="<txp:permlink />" title="Click for this gallery"><img src="<txp:image_url />" alt="<txp:image_info type="alt" />" /></a>
</p>
</txp:images>
</txp:article_custom>EDIT: I guess my bigger question is how to do this if not with native tags? I’m stumped.

Re: Confused by txp:images tag
I guess wrongly @auto_detect=“article”@ works only within . You can try to extract article images from <txp:article />$thisarticle (not tested):
<txp:article_custom section="art" limit="999" sort="rand()">
<txp:images category="homeshow" id='<txp:php>global $thisarticle; echo $thisarticle["article_image"];</txp:php>' break="" sort="rand()">
<p>
<a href="<txp:permlink />" title="Click for this gallery"><img src="<txp:image_url />" alt="<txp:image_info type="alt" />" /></a>
</p>
</txp:images>
</txp:article_custom>Last edited by etc (2012-09-19 19:26:09)

Re: Confused by txp:images tag
etc, thanks! Your solution works and I am going to use it because it doesn’t involve a plugin!
However, in the time between my question and your answer, I figured out how to do it with smd_if as well. Here’s the code for anyone curious:
<txp:variable name="homeshow" value='<txp:images category="homeshow" break="/"><txp:image_info type="id" /></txp:images>' />
<txp:article_custom section="art" limit="999" sort="rand()">
<txp:images auto_detect="article" break="" sort="rand()">
<txp:variable name="current_img" value='<txp:image_info type="id" />' />
<txp:smd_if field="txpvar:current_img" operator="in" value="txpvar:homeshow">
<p>
<a href="<txp:permlink />" title="Click for this gallery"><img src="<txp:image_url />" alt="<txp:image_info type="alt" />" /></a>
</p>
<txp:else />
</txp:smd_if>
</txp:images>
</txp:article_custom>Offline
Re: Confused by txp:images tag
I just tried substituting <txp:images break=","><txp:image_info type="id" /></txp:images> in place of <txp:php>global $thisarticle; echo $thisarticle["article_image"];</txp:php> in etc’s code above and it works too.
<txp:article_custom section="art" limit="999" sort="rand()">
<txp:images category="homeshow" id='<txp:images break=","><txp:image_info type="id" /></txp:images>' break="" sort="rand()">
<p>
<a href="<txp:permlink />" title="Click for this gallery"><img src="<txp:image_url />" alt="<txp:image_info type="alt" />" /></a>
</p>
</txp:images>
</txp:article_custom>Offline
Re: Confused by txp:images tag
<txp:custom_field name="article_image" /> will work too, though some call it hack :)
