OT? Split variable, then POST?

[Robert]

Hello,

I am using a simple HTML form to POST data to my credit-card provider.

However, my credit-card provider has a limit on incoming variables. No
variable can be greater than 256 bytes.

Since my form has a text-area box that may hold data that is greater
than 256 bytes, I must find a way to split these data into 256-byte
chunks before the "Submit" button is pressed.

Can this be done using PHP? Is there a way to accomplish this split
and still be able to use the simple HTML form-action tag for the
actual POSTing?

Thank you.

Not sure what exactly you're trying to do, but... you can create an
intermediate php script to accept the post, do some processing, and then
make a request of its own. Or it might be simpler to split the data in your
script, and write out a new form with hidden fields that submits itself
immediately, though if you're concerned about security or the client doesn't
necessarily have javascript then that's a really bad idea.
