[mapserver-users] basic search question

[kenboss]

It's been a while, but I'll take a shot.  I can think of a couple of ways to get there.  

If you have x,y coordinates for the centers of your parcels in your mysql database, you can just run 
your search, grab the results, and redirect to a url like:

http://myserver.com/cgi-bin/mapserver?map=parcel.map&mapxy=x_from_mysql+y_from_mysql&scale=150000


If you have a common unique parcel ID in both the mysql database and the parcels shapefile, you can 
grab that ID from your search and then redirect to something like:

http://myserver.com/cgi-bin/mapserver?map=parcel.map&qlayer=parcels&mode=itemquery&item=parcelID&value
=unique_ID_from_mysql

In turn, in your mapfile your parcels layer would have a query template like:

http://myserver.com/cgi-bin/mapserver?map=parcel.map&mapext=[shpext]

to display the map.

At least, that's how I'd approach it from ms_3.3.  I understand itemquery has changed in 3.5, and 
there may be better ways to get there.



Hope this helps,
