display all images from a category in an xml file
Hi everyone,
I’m trying to display all my images from category ‘image-gallery’ into an xml file for a flash file to read and generate an image gallery from. So far I’ve not found any info on this, and it seems the image tags such as txp:image_index can’t output what I want as it can’t be told what to output by a form. Does anyone have any ideas?
Ideally I’d like to output something like this:
<gallery> <gallery-item> <image url="url of image" /> <thumb url="url of thumbnail" /> <caption>image caption or alt text here</caption> </gallery-item> </gallery>
Many thanks,
Ben

Hi, a couple of plugins that might help you achieve this:
- mg_setheader : Put this on a Page template to set an XML mime type
- smd_gallery : Generate the gallery itself. You can put the call to this plugin directly on your page so it will insert the relevant tags for each image
For example, on a Page template (untested) :
<txp:mg_setheader /><?xml version="1.0" encoding="UTF-8"?>
<gallery>
<txp:smd_gallery category="image-gallery">
<gallery-item>
<image url="{url}" />
<thumb url="{thumburl}" />
<caption>{title}</caption>
</gallery-item>
</txp:smd_gallery>
</gallery>Does that get you going? It’ll create what I call a “fake” xml file under your chosen section, but if you point your flash file at the relevant section it should read it and interpret it as a proper XML file (he says, hoping…)

Re: display all images from a category in an xml file
This looks very interesting. I had been looking for a way to automate the xml creation so that I could update Monoslideshow from within Textpattern. A typical configuration file looks like this:
<?xml version="1.0" encoding="utf-8"?>
<slideshow>
<preferences
backgroundColor = "000000"
showLoadingIcon = "false"
showAlbumsButton = "false"
showThumbnailsButton = "false"
showControls = "false"
showImageInfo = "never"
imageTransitionTime = "2"
imagePause = "10"
kenBurnsMode = "random"
kenBurnsTime = "7"
kenBurnsVariationPercent = "40"
markFile = ""
/>
<album title="Example album" description="Example description" imagePath="album/images">
<img src="img-01.jpg"/>
<img src="img-02.jpg"/>
<img src="img-03.jpg"/>
</album>
</slideshow>I suppose I could use the article tilte and excerpt fields for title and description respectively. The imagePath would then be txp’s default image directory?!

Re: display all images from a category in an xml file
Bloke,
I’ve had a play round with your plugin – it’s very useful and I’m sure I can use this on a lot of projects thanks very much!
I have one question but I’m not sure how feasible it is – I’m using a multi-lingual plugin called MLP which creates multilingual entries across all my articles and images.
So my current image files have 4 captions and 4 alt entries for 4 different languages. For most stuff MLP will then deliver the correct language for article text or image alt text etc based on the current URL eg. mysite.com/en/section/ for English or mysite.com/fr/section/ for French. However with your gallery plugin it always pushes through the first set of English alt/caption tags. Is this something that can be worked around?
Many thanks,
Ben

Shouldn’t this question really be in the plugin support article? I might have seen it discussed there.

Re: display all images from a category in an xml file
Sorry you’re right wrong section -
well I’m now using smd_gallery for a gallery that does not require MLP, and I’ve managed to get the output I wanted for the MLP section with an ugly hack of upm_image working with wet_for_each_image for anyone interested.
