passing information

[Auddog]

I'm needing to work with a bar code scanner and have come to realize that
after scanning a barcode the unit actually does a hard return. What is the
best way to variables from one page to another. I was thinking of creating
5 pages of for input and the last one would have the submit button. I just
don't what would be the best way to pass the variables from page one, two,
three.. etc to page 5. Thanks for any help you might be able to offer.

Since each form submission is unique (ie: no relation to past form
submissions, as far as the server is concerned), the easiest way to
pass values across muti-part forms is to take those values submitted to
each part and place them in hidden form elements (<input
type="hidden">) and just keep passing them along until you're ready to
process the data.

Re: passing information

Traditionally,

http://www.php.net/manual/en/ref.session.php

and

http://www.php.net/manual/en/features.cookies.php

are the most common flat-file based solutions for getting data to
persist between pages. Normally the deciding factor between the two is
how much information actually needs to be saved, and how secure it
needs to be. The more information / more secure, more likely you are
to want to use sessions. (Generally speaking.)

You could always use a database of some sort as well (SQLite or MySQL,
e.g.) in concert with sessions.

FWIW there are 2 great chapters about this in George Schlossnagle's
book Advanced PHP Programming:

I have essentially given you the 4-sentence version of one of those
chapters' introductory discussion. :)

Most barcode readers come with a book of codes where you can program
the readers behaviour and disable the CRLF if necessary. Normally you
would not want to do this because the whole point of using the reader
is to enter some data and submit it.

Re: passing information

I will have to check that out. I hope there is a way that I can use the tab
instead of the CRLF. That would really make it easy on me.

thanks for all the help.
