How do I forward a variable?

FillePille

I want the next page I visit also should know what the variable "$userid" means.. but it doesn't.. Can I somehow "FORWARD" the variable to the next page?..

you can try using cookies, or the easier by using variables in the url. example : http://www.yourhost.com/index2.php?userid=3
so then in the next page index2.php you catch the variables from the url.

Kidsleep!!! I AM using sessins.. but still.. how do the next php-page know what session I'm in?..

kidsleep

on your first page, you must register your variable.

something like:


session_start();

$user_id="78";

session_register("user_id");

on your next page do something like this:


session_start();

echo("$user_id");

I agree with hermzz

If security is an issue then i would use cookies, aslo if you want it to remember that user then cookies would be best.

If its just a one of thing like carrying there name through to make your site look a bit more personal then i would just forward it in your url so

<a href="nextpage.php?userid=<?php echo $userid ?>">link</a>

Okey, thanks for the session answers...

Anyways, how aout if I COMBINE session_id with a username and password check in the begining of each page,.. ie if session_id is the same session in colums as the password for a certain user.. but then I'm back on page one again,.. I need to forward the password variable.... :/..

Dear Forum,
Does this mean that I must put session_start(); at the start of every page? This seems odd, 'cos I declare variables ( like $url="http://"; ) in the header called by the first file visitors come to, and these variables persist throughout the session. I thought that session_start(); was required only at the start of the whole session, at least, that's what it seems like in the books I've read. Yes/No?
Something isn't doing the biznizz becos the variables passed by the "Submit" button in my forms don't seem to last past the very next page, i.e. the URL mentioned in the <form method=post action=\"filename\"> tag. I'm doing my head in on this, so any help woul be gratefully appreciated.

Thanx, lads.

cookies are not secure in any way for they can be read by any wiseass using a packetsnifer (yeah I know on same lan or network division but still)
Use sessions (and yes you have to start a session in every script BUT IF the $SESSION['IsLogged'] session isn't set redirect to login page and check for user pw and then set $SESSION['IsLogged']).

So that it would be usedull for the HTTP Authentication.

May i ask, should i use the session_register("..."); only once and in particular in my login page?

Another one question is that, if i use a form method=POST, wilbb work for me?

Thanks

Dear BunkerMaster,

Thank you for your swift response. Unfortunately, I don't seem to have got much further.
Following your advice, I put session_start(); at the top of every page and of every header but my variables still don't persist.
I'm not setting cookies at this stage - there's no security problem, the site is just for a cycling club.

I don't know if this eliminates my sending you down dead-end alleys but -
I use an ISP's servers over which I have no control.
I use the method=post thingie 'cos I have no idea why I should use the other one, method=get - or why not!

I asked the server which version of php and it came back 4.0.4.

Someone wrote about setting globals. My book says this is a configuration option and if this was set, all variables would be accessible throughout the session; I suppose the ISP would have set that, wouldn't they? (Can't ask them right now, they've all sloped off home.) I don't need to have access to the server to do that, do I?

My apologies for seeming thick - I'm a newbie with the keyboard in one hand and the php, and mysql, and html manuals in the other.

Yooors,

Iain.

no thickness involved. Everything we wrote about (ie. fancy $_SESSION shit) don't apply to you for the PHP version it was introduced in is 4.1 (you're working on a piece of history if I may say so) so use session_register and use the global arrays from before 4.1
