I apologize if the title is somewhat misleading. What I am trying to do<br>should be pretty common but I have not found a solution.<br><br>Environment:<br> Mapserver 4.6 running under Apache on Windows (soon to be changed to IIS
<br>on Windows)<br> No database. PostGIS or MySQL to be added later.<br> Little experience with PHP, MapScript in learning process<br><br>Data:<br> Shapefiles of US, states, counties (all polygons)<br><br>Desired result:
<br> 1. User brings up map of US and sees outlines of states. (have that<br>working - no problem).<br> 2. User selects a state by clicking somewhere within the state polygon OR<br>enters state name in text box (user choice - either is valid option)
<br> 3. MapServer redraws map with desired state as extents<br> 4. User selects county from state by clicking somewhere within the county<br>boundary polygon or enters county name in text box (user choice - either is<br>
valid option)<br> 5. Mapserver redraws map with desired county as extents.<br> 6. All this should be accomplished using the same base mapfile defining<br>layers, etc.<br><br>Any help with 2-6 would be most helpful. Thanks in advance.
