[edit] Usage

I installed SemanticMediaWiki just to use this extension but I can't seem to get it to output anything. Using the code '{{#ask: Category:Image | format=gallery}}' doesn't do anything (there are images tagged in the Image category). If I just want to use this extension to display gallery's of Category images do I need to do anything with SMW or does it know what the Category tag is? Also, can this extension display the results from multiple categories in a single gallery? Can the query be configured so that it only shows images that, for example, are in both Category:1 and Category:2 but not the all images in either category?

Sorry for the barrage of questions. --38.99.130.13 15:16, 15 January 2009 (UTC)wt-2008

To display a gallery of images from a single category:

 {{#ask: [[Category:Image]] | format=gallery}}

To display a gallery of images that are in either one of two given categories:

 {{#ask: [[Category:Cat1||Cat2]] | format=gallery}}

To display a gallery of images that are in both given categories:

 {{#ask: [[Category:Cat1]] [[Category:Cat2]] | format=gallery}}

I would have replied sooner if I knew of a good way to monitor a particular page for changes through my feedreader (or with email notifications). Good luck! --BigSmoke 19:21, 22 January 2009 (UTC)

BigSmoke - you should click on "watch" for this page, then click on "my preferences" at the top and, in the main tab, select "E-mail me when a page on my watchlist is changed". Yaron Koren 22:30, 22 January 2009 (UTC)

Yaron, Thanks! You're very helpful. :-D --BigSmoke 08:52, 23 January 2009 (UTC)

[edit] Help with install

Thanks for emailing me the scripts. It seemed simple enough, however, when I presumed to add:

require_once( 'extensions/SemanticGallery/SemanticGallery.php' );

to the end of my LocalSettings.php file, it resulted in an error, namely:

Fatal error: Access to undeclared static property: SMWQueryProcessor::$formats in /wiki/extensions/SemanticGallery/SemanticGallery.php on line 23

What did I do wrong? - Thanks!

Is the Semantic MediaWiki extension already working? It should be loaded before the SemanticGallery extension. --BigSmoke 15:28, 4 December 2008 (UTC)

yes it is (as is evidenced by the correctly working semantic calendar) and Semantic Gallery is definately being loaded last.

any other thoughts?

Could you let me know if the version that I put up in SVN fixes this? I see that you're not using the extension in your wiki yet, so I'm curious to know about any problems left. --BigSmoke 19:25, 22 January 2009 (UTC)

[edit] Displaying caption?

hello thanks for this extension. I dont understand on how to display other caption (custom) other than the namespace.

thanks

Never mind got it. I create a property and it display.

Hi there, I still have the same question! How do you get the file descriptions to show up as captions?

Thanks!
