[Mapserver-users] Update: Maybe queryByAttributes should be queryByAttribute

[Ryan, Adam]

For my needs, I've solved the queryByAttributes dilema...I don't use it.

Instead, I take my complex expression and set it as the layers filter...

Subject: [Mapserver-users] Maybe queryByAttributes should be
queryByAttribute



Hi.

Has anyone successfully queried more than one attribute using PHP mapscript,
ie ('[TWNSHP]'='10' and '[RANGE]'='01')?

I can't use this sort of expression in the qstring parameter of
queryByAttributes, and if I try a combination like...

$qclass->setExpression("('[TWNSHP]'='10' and '[RANGE]'='01')");
$qlayer->queryByAttributes("twnshp","/./",MS_MULTIPLE);

...mapserver crashes.  I know my syntax is correct because either of these
works fine independently.  Am I missing a command?

I've tried all kinds of combinations using expression, filter,
queryByAttribute but can't seem to get it right. 

Any suggestions would be great.
