PHP Question = Keeping a Variable

[mkx]

Quick question, I am trying to make it so that a variable is kept even when the user clicks to another page. For example:

They go to www.yahoo.com?ref=55

and then from yahoo they click news. I want it to then go to:

www.yahoo.com/news?ref55

instead of just going to

www.yahoo.com/news



Hope someone can offer a script for this or an alternative easy to use method.

<?php echo  $id[0]; echo $1d[1];?>

you need something like this, the more ID's you add the more code you can carry on your ?id=123456
the above code is good for only two

Thanks, but I don't think this solves the problem on keeping the variable stored so I can use it on the next page. I am testing out some cookie functions now, I think that is what I needed.

well let's say you go to
www.url.com/index.php?id=1234

you can print the variable in your page by using <?=$id?>
so just print it in your link...
(let's say you want news.php to carry the variable you would use

<a href="news.php?id=<?=id?>">

or you can store it in a session variable if you want to carry it around on multiple pages etc etc.....lots of ways to do it..

in this case, what you want is a session variable...

<a href=http://www.nextlinkontthepage.com?ref=<? echo $ref; ?>>link</a>

after you drop the cookie,

<?=$_REQUEST['ref']; ?>

So php checks the cookie, post and get requests for the info.

<a href="news.php?id=<?=id?>">

This seems like the easiest method for what I am doing. Thank you guys so much, nice to get instant php support at 5am ;)

Try using smarty (smarty.php.net), they have something like $smarty -> assign;

asking a php question... and only needing to know how to do that..

that's like stepping into a fomula 1 car and asking how to step on the gas.
