Question

I have a form on a page with get parameters:
index.php?PageID=12

I then have a multiple forms on that page which build up the page details as the user selects the details.

My problem is when the form is posted the Get overwrites other get parameters.

I can use post but then can only post the information back once as the post values are wiped when the next form is submitted;

the idea is the forms build up a address as such;

1. ?PageID=12
2. ?PageID=12&Section=48
3. ?PageID=12&Section=48&Event=1456

and so on as the user selects more items.

Thanks for your help.

Answer 1

For forms with method=get the query string parameters specified in action attribute are ignored. Add such parameters as hidden form fields:

<form action="index.php" method="get">
<input type="hidden" name="PageID"  value="12">
<input type="hidden" name="Section" value="48">
<input type="hidden" name="Event"   value="1456">
</form>

You can use server-side script or JavaScript to add the query string parameters as hidden form fields.
