[Qgis-user] QGIS Server - filtering a layer for display in QWC or get print request

[Bernhard Ströbl]

Hi Carlos,

the filter parameter is described here [1], have never tried it myself, 
though. I doubt you can use a filter parameter in the GetPrint request, 
maybe you should try and if it does not work fill in a ticket (feature 
request), as I think this is a logical enhancement.
Looking at QWC you can display a layer (with all its features) and you 
can search a layer but there is currently no possibility to reduce the 
features being displayed (and I am not sure, if it even should be 
possible). What you can do is load the layer several times in your 
project and set a filter on it in order to have a distinct layer for 
every project location or use the theme switcher and create a project 
for every location.

Bernhard

P.S. Glad you solved the other problem :-)
