I'm new to PHP and although it seems like a powerful construct, I'm getting
very frustrated dealing with sessions. My results seem inconsistent.
I'm simply trying to access the $_SESSION[] variables when I return to the
page with the following code in it but they are always empty--I've tried
moving/removing session_start() but nothing seems to work--the variables are
empty when I return to this page:
<?
session_name('cookiesetter');
session_start();
if (!isset($_COOKIE['testcookie'])) {
if (!setcookie('testcookie', SID)) {
echo "could not set cookie...exiting...";
exit();
}
else {
echo "session_id(): " . session_id() . "<BR />";
echo "SID: " . SID . "<BR />";
$_SESSION['sessid']=session_id(); // just the number
$_SESSION['cookieval']=SID; // session name and number
$_SESSION['sessname']=session_name();
echo "sessid = " . $_SESSION['sessid'] . "<BR />";
echo "cookieval = " . $_SESSION['cookieval'] . "<BR />";
echo "sessname = " . $_SESSION['sessname'] . "<BR />";
}
}
else {
//session_start();
$sessinfo = session_name() . "=" . session_id();
echo "sessinfo = " . $sessinfo . "<BR />";
echo "COOKIE: " . $_COOKIE['testcookie'] . "<BR />";
echo "SID: " . SID . "<BR />"; //SID empty because valid cookie was
retrieved(?) by client
echo "SESSION[sessid] = " . $_SESSION['sessid'] . "<BR />";
echo "SESSION[cookieval] = " . $_COOKIE['cookieval'] . "<BR />";
echo "SESSION[name] = " . $_SESSION['sessname'];
}
?>
Would someone clue me in please? Thanks...
joe
