Hi,<br><br>Where can I find more information about the queryByAttributes() function? I found <a href="http://mapserver.org/mapscript/php/index.html#layerobj-class">http://mapserver.org/mapscript/php/index.html#layerobj-class</a> , but it is not very detailed. By trial and error I found that for a PostGIS layer, I should use this syntax:<br>
<br><span style="font-family: courier new,monospace;">layer.queryByAttributes(map, null, "myfield='searchValue'", mapscript.MS_MULTIPLE);</span><br><br>but for shapefiles, it seems it should be:<br><br><span style="font-family: courier new,monospace;">layer.queryByAttributes(map, "myfield", "searchValue",
mapscript.MS_MULTIPLE);</span><br><br>I am trying to write some generic code, but that's hard if there is no single way to call this method. Also, I haven't found a way yet to do a partial match on a shapefile (PostGIS supports 'LIKE')<br>
<br>Regards,<br>Berend Veldkamp<br>
