AW: [Mapserver-users] itemquery on Mapserver 3.6

[Thomas Zerweck]

Hi,
the layer is defined by the qlayer-statement, and that seems to work since the selected (wrong) feature is a feature of this layer. The regex stuff might be the problem, since in the doku they say the filter string must be a Mapserver regular expression. However, I tried it with  document.mapserv.filter.value="/Munich/" which didn't help. Is there an error in my regular expression?

Hi Thomas,

>                 document.mapserv.target="_self";
>                 document.mapserv.mode.checked=true;
>                 document.mapserv.mode.value="itemquery";
>                 document.mapserv.qlayer.value="cityareas";
>                 document.mapserv.filteritem.value="NAME";
>                 document.mapserv.filter.value="Munich";

I think the problem is that you don't refer to a layer specific filter. If you want to assign a filter via URL use this syntax "map_layername_filter=yourfiltervalue". It might also be important to include in your filterstring how to query for results (string, logical, regex
comparison), for regex comparisons you should enclose your statement in //, e.g. "/your_regex/", for logical expression in () for string expressions in "".

HTH, Michael
