I spent a lot of time on Friday trying to figure out how to replicate an
ask query in PHP. I was pretty sure I could do something to reuse the
parser, but since I wanted to be able to manipulate the data before
displaying it I did not pursue that method. Thank you, Frank, for the way
you described. I'm sure that will come in handy in the future.
I also spent some time messing around with QueryProcessor. I agree with
Jeroen that the result data is odd, and I came to the conclusion that I
must have been doing something wrong.
This morning I looked at Yuri Katkov's examples provided by Toni [0], and
as MWJames said they do not work with SMW 2.0. Below I have modified Yuri's
"all pages with the property" example [1], and upon immediate inspection it
appears to be working. I plan on modifying Yuri's more complex examples to
work with SMW 2.0, but would like any input if I'm doing anything wrong
here. Also I'll make the examples do something more interesting than
print_r.
// Perform query replicating {{#ask: [[Age::23]] }}
$numberValue = new \SMWDINumber( 23 );
$queryDescription = new \SMWSomeProperty(
new \SMW\DIProperty( 'Age' ),
new \SMWValueDescription( $numberValue )
);
$query = new \SMWQuery( $queryDescription );
$store = \SMW\StoreFactory::getStore();
$result = $store->getQueryResult( $query );
print_r( $result->getResults() );
