Get vars from different form on same page

[Dean_Glass]

Hi Guys / Girls,

I have been searching the forums and nothing quite matches what I am looking for.

My state is that I have three forms on the same page; main, upload and view upload forms that appear depending on permissions.

How can I get the upload form (2) to get a textbox variable from form 1 (main) on its own submit and then pass it on through its own "hidden" attribute element?

Any help would be greatly appreciated, and I apologise if this has been answered before.

The probable reason why you haven't found an answer in these forums is that, since this is something that is supposed to happen on the client, is a (basic) Javascript question, and these are PHP forums.

What you want your Javascript onSubmit handler to do is to get the "checked" property of the checkbox (I forget the cross-browser syntax because I use getElementById() when I can) and set the value of hidden element to something depending on whether that property is true or false.

Use one form, then use arrays to split out the different "forms". For example:

<form method=post action=myscript.php>
<INPUT TYPE=TEXT NAME=auth[login]>
<INPUT TYPE=PASSWORD NAME=auth[password]>
<INPUT TYPE=SUBMIT NAME=action[auth] VALUE="Login">

<!-- lots of stuff in the middle -->

<INPUT TYPE=TEXT NAME=search[city]>
<INPUT TYPE=TEXT NAME=search[state]>
<INPUT TYPE=SUBMIT NAME=action[search] VALUE="Search">
</FORM>

Now, to process this form:
<?
// which submit button did they click on?
$action=array_keys($action);
$action=$action[0];

if ($action=='auth')
