Zoom to custom extent - PHP

[Kevin Grootendorst]

Hi Bill,
The quick zoom seems to be working now, but the ROSA tools do not respond,
nor does the legend/layer list.  I moved the code in the 'contents.php'
to 'higher up' in the file (no longer at bottom).  Once I select the region
from the dropdown list, and click refresh, the map zooms to where it
should.  However, the list defaults back to the first option.  It would
also be nice to implement an 'onchange' event, so that I don't have to use
the refresh button to zoom to the region (I'm wondering when things do
work, if adding a layer and refreshing will automatically zoom to the first
extent in the 'View Region' drop down list).
