Display newest image in a category

ashground · 2006-12-20 18:21:15

Essentially, I want to do this:

<img src="images/[image].jpg" alt="[alt]"/>
<p class="info">
	[Image description]
</p>

… where [image] is the newest image in a category. I know there are plugins to display the newest image in a category, but they’re part of gallery plugins (and always insist on turning the image into a link, or only show the thumb and not the whole image).

Is there an easy way to do this?

With a little help from wet_for_each_image this would be quite simple:

<txp:wet_for_each_image limit="1" category="mycategory" sort="date desc"><txp:image id="{id}" /></txp:wet_for_each_image>

More complicated image layouts can be accomplished by a mashup of wet_for_each_image and upm_image. Just have a look at the samples, you’ll get an impression of how to achieve what you want.

If I try using wet_for_each_image on its own, it works fine (thanks for the plugin, wet), but only offers a way to display the image and not the caption. So, I installed upm_image, and once again I can display the image fine. But the moment I try displaying the caption, things go awry.

This is what works:

<txp:wet_for_each_image limit="1" category="Home-page" sort="date desc">
<txp:upm_image image_id="{id}"/>
</txp:wet_for_each_image>

But then, to display the caption, I made this change:

<txp:wet_for_each_image limit="1" category="Home-page" sort="date desc">
<txp:upm_image image_id="{id}" form="img_caption" />
</txp:wet_for_each_image>

… and made a misc article named “img_caption” with this inside:

<p class="info">
	<txp:upm_img_caption />
</p>

The result vomits all over my page:

An error occurred in the following tag: <txp:upm_image image_id="3" form="img_caption" /> ->  Notice: Undefined variable:  form_name  on line 413

… and…

An error occurred in the following tag: <txp:upm_image image_id="3" form="img_caption" /> ->  Textpattern Notice: Form not found:   on line 1332

I double-checked the form name and everything looks okay. I tried changing the form type, too, trying both misc and article, but it doesn’t seem to make a difference.

Any thoughts? I’ll leave the error up for the next while.

I’m using upm_image 0.4.4, which works as expected. Judging from line numbers at which your error is thrown you are using some other version. Installing a fresh instance of upm_image might be worth a try.

I’m actually running version 0.5 of upm_image. I’d try 0.4.4, but I can’t seem to find any older versions of the plugin archived.

I actually use article_custom on my homepage and my list pages .. it’s for a particular section “photos” but there is also a “category” aspect of the tag .. might do what you want it to do .. maybe

[home - most recent]
<txp:article_custom allowoverride="1" form="picture-form" limit="1" pgonly="0" section="photos" status="4" />

[inside - random image]
<txp:article_custom allowoverride="0" category="photos" limit="1" form="picture-rand-form" pgonly="0" sort="rand()" />

Here’s a tag trace:

<txp:wet_for_each_image limit="1" category="Home-page" sort="date desc">
	[SQL (0.000274): select id from geeztxptxp_image as txp_image where 1=1 and category in ('Home-page') order by date desc limit 0,1]
	<txp:upm_image image_id="3" form="img_caption" />
		[SQL (0.000170): select * from geeztxptxp_image as txp_image where id = '3' limit 0, 1]
		[SQL (0.000164): select Form from geeztxptxp_form as txp_form where name='']
</txp:wet_for_each_image>

That’s interesting. It’s not picking up the form name from the tag at all. Maybe Mary needs to take a look?

Why would article custom not work ?

With the bug fix, the form is displaying properly, but amusingly I’ve lost the image. I hadn’t changed a single line of code.

I’ve temporarily fixed it by changing the form to this:

<img src="<txp:upm_img_full_url />" alt="Home"/>
<p class="info">
	<txp:upm_img_caption />
</p>

(As for article_custom, the site is for a client, and the way I need things set up doesn’t make article_custom an option. That would have worked, though.)

…but amusingly I’ve lost the image.

You would, as that was all you had told it to display; when you use a form, it displays only exactly what you tell it to. :)

Ah, that would make sense, then. I had assumed that by specifying a form, it was going to output the same as the original tag with the form appended to the end. Not sure why I was thinking that, because this makes a lot more sense. :)

Thanks for your help, Mary and wet, and thanks for the plugins
