I am trying to get a handle on setting and retrieving cookies. I think I might have it down, but I'm not sure... if anyone can help, please reply.

to set a cookie, I have only two variables, the user name ($user) and their password ($password)... okay, so I want to set this cookie after they logon.

I use: (this is more of a question than a statement)

<BLOCKQUOTE>code:<HR><pre>
setcookie("username",$user,time()+31536000);
setcookie("password",$password,time()+31536000);
[/code]

and this should set the cookie(s), right? I think this should go before the <html> or <head> tags in my page (so basically, the VERY first thing in my page should be this, if I'm setting the cookies)

To retrieve the cookies, I use : (again, another question based statement)

<BLOCKQUOTE>code:<HR><pre>
....
[/code]

okay, so I don't know how to retrieve information from the cookie.

Any help would be greatly appreciated, correcting my setcookie code, and completing my retrieval information. I am kinda new to php, not totally dumb to programming, but lost on cookies <G>

Thanks,
Mike

your setup cookie is correct..

i am writing an easy example for cookie:

setcookie("CookieID", $USERID);

To retrieve the cookies from above example you can use..

print $CookieID;

ie,Name of the cookie..

Alright, so if the top of my web page looked like this:

<?php3
setcookie("username",$user,time()+31536000);
setcookie("password",$pwrd,time()+31536000);
?><HTML><HEAD> ...........rest of page ....

that would set my cookie, and later in the site I use $username and $password as my variables to reference their cookie? There's no "getcookie" function or anything?

Thanks,

Mike

Hi Mike,

If the cookies have been set, then you can simply refer to their values in other php pages (within the same domain/directory the cookie is set in) with the variables $username and $password.

Try this to see whether the cookies are there:

Make a file (viewcookie.php3 or so), like:

<?
if(isset($username) and isset($username))
{
print $username . " n";
print $password . " n";
}
else { print "No cookies have been set!"; }
?>

Have a nice meal!

Peter
