[Mapserver-users] Re: query a shape using mapfile

[woodbri at swoodbridge.com]

Pedro,

First, please send queries to the list as there are many people that 
can help and you al less likely to get ignored :)

Once you have done your query in mapscript you need to get the shape 
object from the result and read its extents, You can then use the 
$map->setextent(...);
to set the extants to the extents of your query results extents and 
redraw the map.

This is a high level how to, you will need to read the Mapscript 
reference and work out the details. If you get stuck ask the list, 
I'm sure one of us will be happy to help.
