i-frame to do your processing. You could then open your dataset as a shapefile
object and loop through and match the attributes. Once the attributes match,
you will know the extent. Using a separate i-frame gives you all the benefits
of submitting a page (i.e. PHP code processing) without submitting your application
page.<o:p></o:p></span></font></p>

in my template, which holds a page that allows for selecting a layer to search,
and then searches for the searchstring in all the attributes of that layer. I'm
actually running this independently of the rest of the site (the page does not
get submitted for a search, only the iframe is). I store the extent in the
attributes, and use javascript to make the mapimage zoom to the extent of the
objects(s) it has found. My problem is how to get the real spatial extent of
the object. I'm using a basic php script that finds out the name of the
dataset, opens its dbf, and searches the attributes. I suppose this is not
ideal, since it does not interface with chameleon. It's kind of patchy.</span></font><o:p></o:p></p>
