[OpenLayers-Users] triggering a submit with permalink parameters?

[Tara Athan]

I have a website which is acting as an interface to a garden-variety 
MySQL database ( lat/ lon fields).
I have an HTML select field set to trigger reloading of the  page with 
"onchange" (because a database query and a bunch of php is required when 
this parameter is changed).
As it is currently implemented, the map loses its place (the center and 
zoom the user has navigated to) when this happens.
I would like to use ArgParser to accomplish this, but I can't figure out 
how to pass the latest values of the
map center and zoom to the form action url.

I feel like I must be missing something simple- is there a 
straightforward way of doing this?

Here's the URL of the test page

Thanks in advance for your help, Tara
