[Mapserver-users] queryByAttributes Mapscript

[Armin Burger]

Sven,

the attribute query is done by setting a filter first, e.g.
  $layer->setFilter($queryexpression)
and then performing the query
  $layer->queryByAttributes(...)

where $queryexpression can be any definition described for the filter/class expression of the map file.
