Re: [Semediawiki-user] Fw: "further results" of inline query to display images?

[don u. <don...@ya...>]

I've been looking at this, tracking code all over the place.

The problem seems to be, that in the initial {{#ask query page, the function hook doAsk is called, and the results are passed along for additional wiki parsing. IE, it may return a peice of text for a result, that looks like [http://servername/image.jpg] .
This is because the queryResultPrinter's getResult method, is called with the outputmode SMW_OUTPUT_WIKI.
Then, farther up the stack, that will get recognized as an image, and rendered as such.

On a Special:Ask, page, howerever, the processesing is different.
in SMW_SpecialAsk.php, roughly line 270 (I've got too much debug code in there to be sure of exact line numbers),
the queryResultPrinter's getResult method is called with outpputmode SMW_OUTPUT_HTML, which allows the links (properties of type "_uri" to get rendered as links; there's no check to see if the links are images and should be rendered as such. 

and the results don't go through any additional wiki parsing. So I can't just change the output mode to SMW_OUTPUT_WIKI there, unless there's a line I can insert to say "do additional wiki link parsing"

When calling getResult with outputmode SMW_OUTPUT_HTML, the url ultimately gets passed through Linker->makeExternalLink .

That method has a function hook call, LinkerMakeExternalLink, which makes me think maybe we could override the functionality here somehow. What do you think of that?

basically, the initial query results page, and the "further results" page , are executed within very different contexts.

That sounds like a bug in Special:Ask - it's meant to basically replicate exactly what shows up when you run inline queries in other pages, but it doesn't always. If you're willing to look into it, that would be great - all the relevant code is in /specials/SpecialAsk/SMW_SpecialAsk.php.
