[mapserver-users] php mapscript loadQuery problem

[Moen, Paul T.]

What would I use for a CLASSITEM when my expression is a Logical “MapServer expressions”?

For example.

EXPRESSION ('[SURFACE]' == 'Paved' AND '[ROADCLASS]' == 'Primary')

Thanks,

Paul

This would happen if you have classes with string constants (EXPRESSION 
"...") or regular expressions (EXPRESSION /.../), but you did not 
specify an ITEM in the layer definition (so MapServer has no attribute 
value to use in matching the expression).
