[Chameleon] How to pass forward user specific extents?

[Ken Sanderson]

That worked perfect Bill, thanks!!

One last question, well atleast in regards to this topic. Is there a way
to set the current view extents vs the overall extents? Basically I need
the user to go to their prefered starting extent, but if they hit the
'zoom to full extents' button it should take them to the overall extents
of the MAP file, not the ones I have just set via the setextent()
function. Right now, if you use the 'zoom to full extent' tool it takes
them to the values I set with setextent() at instead of the full map
extents.

Hope that makes sense. I am thinking I need to save the original extents
to variables and then reset it after the original load?

Ken,

Add a hidden input tag like:
<input type="hidden" name="myLoadCheck" value='1'>

Use php to check the form variables that are passed over the URL.  On 
the initial load the form variable "myLoadCheck" will not be set so you 
know it is the first load.  Subsequent page load will have the variable
set.

something like:

$bNotFirstLoad = ( isset( $_GET['myLoadCheck'] ) ||
                   isset( $_POST['myLoadCheck'] ) );

I haven't tried it, but something like this should work.

Regards,
Bill
