Means of passing variable from 1 page to another.

[bdichiara]

Ok, I'm running into a slight problem.

I'm using an application called HTMLDOC which generates PDFs from webpages (or HTML). Everytime I pass a variable through the url to this application, i get an error. What other means are there of passing a variable from one page to another.

I've tried using:
$_GET
setcookie
$_SESSION

All of these produce negative results. One last method I haven't tried, which I will try next, is writing a 1/0 to the database and pulling that record out. That just seems a little too complicated for what I'm trying to accomplish.

Are there any other ways of getting a variable from 1 page to another (besides POST and using globals on)?

besides POST and using globals on

Why would you ever want register_globals turned on?


Anyway, insufficient data for a meaningful answer. "I get an error" is vague.


I have successfully used session variables to transfer data between successive scripts when those scripts output HTML, plain text, JPEGs, PNGs and PDFs.

This is entirely what sessions were invented to solve. Try again with sessions.

Ok, i must've been doing something wrong. I gutted all the sessions code and started over, and now the session variable works. Thanks.

If you tell us what error you reported earlier, perhaps one of us can tell you what happened with your code. That way, you won't have to fumble blindly to bypass the error next time you see it.

Well, the error was specific to HTMLDOC, I believe, and not sure if this forum is the right place for that. But if I recall it was something like:

File does not begin with '%PDF-'.

Yep, that's not a PHP error that I've ever seen.

Although now that I think about it some more, that HTMLDOC error could be easily caused by a PHP error. If a PHP script bug caused a warning or error to be output, then that could be why the document does not begin with "%PDF-".

One technique that could help you debug this error is described in section 2.6 of faq434-2999. If you use telnet to fetch the document, you might be able to see exactly what, instead of "%PDF-" was output first. If that first output's a PHP error, you now can correct code.
