[mapserver-users] Attribute query using PHP/MapScript

[Stephen Lime]

While I've not done this per se, the best way to do this would be to:

  - create a map file that would create maps showing all parcels and other data

now in the application:

  - do the mysql selection
  - use the resulting pins to create a custom expression for the parcel layer to 
    issolate just those parcels with matching pins
  - draw the map

You can make that expression "sticky" easily by storing the pins or by using
a straight mapserver CGI application and setting the expression dynamically
using the syntax "&map_parcels_class_expression=...&". That way you could
use PHP to do the query and initialize the mapping app.

Hi Jolks

I'm trying to build a page which allow the user to query the parcel data by
address, pin, and owner name. I first query the attribute table in MySQl
dtaabase and get a list of all parcel "pin"s. then i need to query the
parcel shapefile to highlight all the returned pin's.

Can any give tell me how to query the parcel shape file and highlight the
results in PHP/Mapscript ?? I'll apreciate if you can send me a link to a
similar example


Thanks alot
