I am adding variables to an URL, using GDownloadUrl, then extracting
the variables with php and using them to query a database.


Basically I am following the tutorial Creating a Store Locator with
PHP, mysql and Google maps  at 
http://code.google.com/apis/maps/articles/phpsqlsearch.html

My problem is that I have a lot more search fields than the example.
I suppose I could work out the URL by calling the getElementById
function many times.  However this seems a bit silly when a simple
form and submit button would do all the URL encoding work for me.

Is there a way to make a long URL than goingthrrough each input
element and extracting the information one by one?

any help appreciated.
