Re: [mapserver-users] Dynamic LabelItem
That particular portion of MapServer has undergone a lot of change. At first I removed too much functionality in 5.0, then exposed a bit more in 5.2 and probably got a lot closer to right in 5.4. You're safest with 5.4.1 if you can afford to upgrade. What version exactly are you using?

Re: [mapserver-users] Dynamic LabelItem
I know, and I want all that new functionality :) I am using 5.0.0 I did try an upgrade a couple of weeks ago, but we had hassles with existing application running with openlayers as the frontend, where it displayed the the whole map file image in each map tile as opposed to cutting it up (if that makes sense!). also, our getLegendGraphic requests didnt work after the upgrade. We therefore quickly restored back to 5.0.0. The straight mapserv request was working fine, so it is more a openlayers issue - however - we could not go through and sort out all our existing apps, so thats why we downgraded again. I have just downloaded the 5.4.1 beta MS4W from maptools and will try that tonight, and see If i can get my openlayers resolutions correct Andrew Steve Lime wrote: That particular portion of MapServer has undergone a lot of change.

[mapserver-users] Dynamic LabelItem
Hi All We are using mapserv cgi to generate WMS and access via openlayers. Searching reveals that it is not possible to dynamically change the labelitem by substitution i.e LABELITEM='%LABELFIELD%' Is it possible however to do it via map_layername_labelitem=labelfield in your url, or any other such method. Any help would be really appreciated, because otherwise it means creating different layers for each labelling option.

RE: [mapserver-users] Dynamic LabelItem
Searching revealed that it is possible to change a labelitem by substitution. Have you had a look at this page? http://mapserver.org/cgi/controls.html Scroll down to the header 'Using MapServer version =5' In the below example, the layer name is 'aqiAreas' and I am changing the column to be used to 'NAMESAFE'. I am referencing the layer by name and then after the '=' sign, you put the property that you want to change (labelitem), a space, and then the name of the new column to be used. http://localhost/cgi-bin/mapserv.exe?map=/ms4w/apps/imap/labelitem-test. mapmode=mapmap.layer[aqiAreas]=labelitem%20NAMESAFE David. PS. If this question was about whether OpenLayers passes on your custom URL vars to MapServer in a WMS call, I am not so sure about that. I believe that more recent versions to, but that would be a question for the OpenLayers list. -Original Message- From: mapserver-users-boun...@lists.osgeo.org [mailto:mapserver-users-boun...@lists.osgeo.org] On Behalf Of stretch Sent: Monday, June 29, 2009 1:08 PM To: mapserver-users@lists.osgeo.org Subject: Re: [mapserver-users] Dynamic LabelItem Anyone have any ideas? stretch wrote: Hi All We are using mapserv cgi to generate WMS and access via openlayers.

Re: [mapserver-users] Dynamic LabelItem
MapServer 5.4 does open up this possibility. It's not done via substitution but rather by passing a bit of mapfile syntax. For example, ...map.layer[foo]=LABELITEM+newitem... However, you must set a validation pattern for MapServer to compare the new value against before it will change it. So your layer definition might look like: LAYER NAME 'foo' ... VALIDATION 'labelitem' '^item1|item2|item3$' END ... LABELITEM 'item1' END In this case you could dynamically change LABELITEM to item1, item2 or item3 but item4 would throw an error. Hope this helps.
