[Chameleon] How to pass forward user specific extents?

[William A. Bronsema]

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
