[mapserver-users] FILTER and MapScript

[Armin Burger]

Guillaume,

I think that a filter on alphanumeric fields needs also the field name to be set in single quotes, like

  setFilter("('[$field]'".$operator." '".$value."')")

and for numeric fields no single quotes at all.

I also think that field names for shapefiles need to be in upper case.
