queryByShape Problem

Thanks for the reply Guillaume, 

So you're saying that in order to use this function I need

	$anyLayer->queryByShape($polygonShape)

Which is what I'm doing, or does this function require

	$polygonLayer->queryByShape($someShape)

Which won't work for me?

I've also tried queryByRect, which also fails. Is there something else I should consider? I've tried to ensure that projections and tolerances are set properly...

Hi Josh,

See mapscript documentation about this function :
Query layer based on a single shape, the shape has to be a polygon
         at this point.

Sorry !
