Try adding a limit as a stop-gap. The problem is that by default the limit is 0 (“all”) which for reasons of vagaries in the code (line 2950 of taghhandlers.php) won’t actually trigger the offset to fire in the SQL. That should probably be changed but I think I tried it before and it fell apart under certain conditions. I could try again, or maybe someone else has some bright ideas.

That works! Now I just have to figure out a way to add a limit equal to X-1 where X is the number of image ids provided. There must be a txp:variable way to do that. Thanks again!

Awesome! Thanks!

I take that back— providing a limit of any amount greater than or equal to the number of image ids works totally fine. (Just like the article tag, duh!) I could use the limit="99999" trick, but in this case 99 is more than enough.

Sorry for the slow draw, and thanks again!

Last question of the night: Is there any way to specify an deliberate, non-systematic sort order in the image_list tag? soo_image used the order of the given image ids to sort the output, but image_list defaults to name asc.

For the case I’m testing, I just renamed the files, but I can see how this wouldn’t be ideal in other implementations.

Not without some trickery. You can use the MySQL¹ cheat:

sort='FIELD(ID,5,3,2,4,1)'

but that’s not much use if you need the order to be read from the article_image itself. Now, if you were using a custom field then it’s easy:

sort='FIELD(ID,<txp:custom_field name="sort_order" />)'

But as I found to my detriment last night, the article_image field can’t just output its raw values: it always makes an image tag out of its content. Perhaps this is the last obstacle we need to address to make image handling complete: some way to tell article_image to output either:

the full <img> tag as normal from either the ID, name, or URL in the field
the fully qualified URL of its (sole) content
the raw value(s) in the field itself — like a custom field

I seem to remember having a go at doing this at the time I did the image_list system but failed to make it robust enough/useful/not confusing. If anybody wants to have a go at doing this quick-smart then it would be a useful fix as I think that’s the last area where upm_image outshines the new core tag suite.

¹ Please note that this is a MySQL feature only (as far as I’m aware) which is not a problem now, but may be in the future of TXP if we start to support other DBs.

Hi Stef may be you can use article_image like this:

sort='FIELD(ID,<txp:custom_field name="article_image" />)'

must be work! (not tested)

We’ve rather drifted away from the topic, so I’ve answered in the Images are 1st class citizens of TXP thread.

jsoo · 2010-09-29 12:40:05

And to get back on topic :)

In the demo I neglected to make full use of image_list’s nifty automatic context checking. I used it for article context, but not image category context. I’ve updated the demo to do so; results in cleaner code for the gallery example.

I can’t get it to work with this line in the Javascript

document.getElementById('sooGalleryCaption').childNodes[0].nodeValue = showThis.title;

jsoo · 2010-09-29 14:48:02

Are you saying the demo site isn’t working correctly for you, or that you’ve tried to test it on your own server and it doesn’t work?

FireFusion · 2010-09-29 14:55:02

My own server. Firebug says

document.getElementById("sooGalleryCaption").childNodes[0] is undefined

Yet the images do have titles.

Right, but did you add an element for the caption, as in the example?

<p id="sooGalleryCaption"><txp:image_info /></p>

FireFusion · 2010-09-29 15:07:30

It’s ok. Fixed it. The element was blank on the first image. Thanks :)
