Re: [SMW-devel] Set a SMW property programmatically in PHP?
Hi Nischay, Markus, and Yaron,
Thanks for your feedback. I replied to Yaron but neglected to reply-all to
the list: I did indeed ended up going with just manually embedding a
{{#set:}} in the page programmatically because it seemed overall safer and
easier to manage. Cindy Cicalese actually gave me the same warning about
having to re-set the data on page refreshes. :)

[SMW-devel] Set a SMW property programmatically in PHP?
Hi SMW community, I have a hopefully simple question. Is there a way to set an SMW property for a page programmatically in PHP? Suppose I have access to any of the relevant information, like the page ID. For context, I'm writing an extension which, among other things, creates wiki pages using $wikipage->doEditContent(), and I'd like to be able to set a semantic title <https://www.mediawiki.org/wiki/Extension:Semantic_Title> property on the page at that point. Thanks! -- Jason Ji jason.y...@gmail.com -- Monitor 25 network devices or servers for free with OpManager!

Re: [SMW-devel] Ask query in extension
If your extension includes a JavaScript component, and you need to make the
ask query in the JavaScript, SMW includes the ask query as an API module
(action=ask or action=askargs, depending on what format you prefer to send
in the query).

[SMW-devel] Deleted page still appears on a Category page
Hello, I have a wiki running MediaWiki 1.23 and Semantic MediaWiki 1.9.1 in a development environment (so lots of page creations, deletions, settings changes, etc). I was also messing around with semantic forms, properties and templates and using content-free page naming with semantic title. At some point during my development today, after I changed some settings in PostConfiguration.php regarding namespaces (including wgExtraNamespaces, wgContentNamespaces, smwgNamespacesWithSemanticLinks, and one or two others), I found that a page which I had deleted was still showing up in a Category page of which it was a member (when it still existed). Clicking on the link to the deleted page takes me to the deleted page (correctly stating that the page was deleted, but I could restore it if desired). To be clear, this was a built-in MediaWiki category page - the template I was building would put these pages into that category. If it helps, this page was using content-free page naming, so it had a title like "Item:1" and a semantic title like "A Test Page". When the page is deleted, it shows up in the Category page just as "Item:1". When not deleted, it shows up in the Category page twice, as "Item:1" and as "A Test Page". Subsequent pages like "Item:2" only show up in the Category page with the proper display title, and only when the pages exist (not when deleted). I have tried things like re-creating and deleting the page, running refreshLinks.php, runJobs.php (until the job queue was clear), and SMW/UpdateJob.php (this last one indirectly via the Special:SMWAdmin page), but none of these have fixed the problem - the phantom page is still showing in the Category page. Can anyone give any insight as to a) why this might happen, and/or b) any other ways I can try to correct the problem? I posted this question to the MediaWiki email list yesterday, and it was suggested that I try the SMW email list too.
