Javascript To Submit Variable

[sess4561]

Hi guys

I was wondering if anyone knew how to populate a variable in PHP from a user submitted textfield, without using POST or GET?

I think this could be done using Javascript but not sure on the method to do so. (onfocus?)

Basically what I want to do is create a unique variable instantly from what the user puts in.

For example:-

//THE FORM
Name: J Smith
Age: 20
DOB: 300181


//PHP
$userref = "abc123";
$thevariable = "JSmith20300181abc123";

The variable would then be included as a hidden field, so when the user submits the information is present.

Any ideas?

Thanks

"so when the user submits the information is present."
Well then it is using POST or GET, is it not?
