save form values to sessions

[chrislive]

hi everyone,

I have a standard form however one of the values is retrieved through some javascript popup functions.

What I want is to be able to set a onunload function that will save all my current form fields into sessions and then refresh. once refreshed it will check for the session values and add them back into the fields (so entered data is not lost on the refresh.

if possible i do not want to have to enter the field names but to take ALL fields and values from the page.

So how do I make this work without actually submitting the form?

You cannot do this without posting, or at least refreshing the page (So, there ahs to be data transmitted between server and browser).

PhP, and therefore the $_SESSION run on the server. Your javascript runs on the client.

Hm.. Why do you want to store all in a session? Are you moving through a series of forms?

I am not sure, but I am afraid you will have to call each variable to echo it into the form-element specific locations.

hmmm basically this is what I have...

say page1.php

<form name="form1">

<INPUT TYPE="text" SIZE="30" NAME="field1">

<INPUT TYPE="hidden" NAME="field2">
Popup Link page 2

<submit>

</form>

page2.php
<form name="form2">

<INPUT TYPE="text" SIZE="30" NAME="field2_select">

<submit> // submits field2_select into field2 within form1 and closes popup.

</form>

So I have the value I want in a hidden field but I want to display this nicely to end user, so I want to refresh the page and then I can query the db and format based on the value of field2. but I dont want to loose what has been entered already.

perhaps js is the best bet for what I need, but noone is answering me in the js forums

If you need to exchange some data between browser (client) and the server, consider use of xmlhttprequest and/or JSON; both should give quite good results if implemented correctly.

Goooooooogle for more.

this one was pretty simple. First of all this needed to be done in pure javascript. You just needed to be able to reference the opening window's form and field value. This is done like this.

function fillInParent()
{
window.opener.f1.t1.value = document.f2.t2.value;
}
