large form and sockets

[gnome5482]

Ok, I've been stumped on this one for a couple of days now and nothing I do seems to work. I have a page with 41 checkboxes and 10 textboxes on it (on the same form). I have a script called on this page that fills the checkboxes/textboxes with data based on information sent back from a server using sockets (fsockopen). I need a way to determine which checkboxes/textboxes have been changed and submit only that information to the new php script and have all that data sent to the server using fsocks.

There is a catch though. I can't use an array on the html form because I need to send each command (*box) to the server via fsock and the format is "command "value"" (command and value seperated by a space). I don't need to know that data came back from the server, only that it was sent.

If you need more detail just ask and I'll post an example of what I'm trying to do.

How do I go about doing all of this?

So you get information from a server, and you use that information to pre-fill/-check some textboxes/checkboxes? And when the form is submitted back to you, you want to know only what has changed?

My first thought is to use some hidden fields in the form that contain the original values. That way, you can loop through the fields that were posted and check if they are different.

If you can provide some examples, I might be able to show you a quick coding example.

I get the info to fill checkboxes/textboxes from an included php script. The user is then able to change those values (ie: check/uncheck) then click a submit button. That button posts the data to a new page which tells the user to wait for a moment. What that page is doing is reading all the post data and then using a socket to connect to a remote UDP server to send all the commands and new values.

What I'm trying to figure out how to do is send all that data to the UDP server without having to open/close a connection for each command. And if there is a way to know which values specifically were changed then I could updated those instead of sending the entire list of items to the server.

I have a code sample that you can see that will show what I am trying to do. I've only used a few commands for this one and all the info here is bogus, but it will let you see where I'm headed right now.
