[mapserver-users] About FILTER and FILTERITEM

[Rahkonen Jukka (Tike)]

Hi,

>From document page: http://mapserver.org/mapfile/expressions.html
"To use a string comparison for filtering a LAYER, both FILTERITEM and FILTER must be set. FILTERITEM is set to the attribute name. FILTER is set to the value for comparison. The same rule applies to CLASSITEM in the LAYER object and EXPRESSION in the CLASS object."

That would mean that only one attribute from the data can be used for building a filter. Is this true or just old information living in the document?
