[mapserver-users] Fwd: querybyattributes

[Patricio Gigoux]

Hi
yes, I need know what are the steps for use and get correct answer from 
querybyattributes.
But i read from de documentation the next:
 int queryByAttributes(int mode)
         Query layer for shapes that intersect current map extents.
         The query is performed on all the shapes that are part of a CLASS 
         that contains a TEMPLATE value or that match any class in a
         layer that contains a LAYER TEMPLATE value.
         Mode is MS_SINGLE or MS_MULTIPLE depending on number of results
	    you want. 
 	    Returns MS_SUCCESS if shapes were found or MS_FAILURE if nothing
         was found or if some other error happened (note that the error 
         message in case nothing was found can be avoided in PHP using 
         the '@' control operator).

then I use:
layer->setfilter("[campo]=$var");
layer->querybyattributes(MS_SINGLE);

But it doesn't give me good result
How do I have to do it?

Thank you
