Migrated from MySQL 4 to 5 (now session access doesn't work)

matrixx1 · May 17, 2011

I have a site with a members area that uses sessions. I migrated my DB from MySQL 4 to 5. Now my login page does not work. Please help.

Member Login Page:

<?php
session_name ('name');
ini_set ('session.use_cookies', 0);
session_start();

After the credentials are entered the user is returned back to the login page and NOT the member's page.

This is the userlogon.php page:

<?php
$link = mysql_connect('localhost:/tmp/mysql5.sock', 'dbuser', 'dbpw');
if (!$link) {
   die('Could not connect: ' . mysql_error());
}

//mysql_close($link);

if (!mysql_select_db('db_name', $link)) {
   echo 'Could not select database';
   exit;
}


$username =  $HTTP_POST_VARS["username"];
$password =  $HTTP_POST_VARS["password"];
$member_id = '';
$role = '';
$firstname = '';

// Formulate Query
// This is the best way to perform a SQL query
// For more examples, see mysql_real_escape_string()

$query = sprintf("SELECT users.member_id, users.username, users.password, users.role, FROM users join members on users.member_id = members.member_id WHERE users.username ='%s' AND users.password='%s'",
   mysql_real_escape_string($username),
   mysql_real_escape_string($password));

// Perform Query
$result = mysql_query($query);

// Check result
// This shows the actual query sent to MySQL, and the error. Useful for debugging.
if (!$result) {
   $message  = 'Invalid query: ' . mysql_error() . "\n";
   $message .= 'Whole query: ' . $query;
   die($message);
}

// Use result
// Attempting to print $result won't allow access to information in the resource
// One of the mysql result functions must be used
// See also mysql_result(), mysql_fetch_array(), mysql_fetch_row(), etc.
while ($row = mysql_fetch_assoc($result)) {

   $member_id = $row['member_id'];
   $username = $row['username'];

    $role = $row['role'];

}

if ($member_id != ''){
session_start();

$_SESSION['membername'] = $username;
$_SESSION['username'] = $username;

$_SESSION['memberid'] = $member_id;
$_SESSION['role'] = $role;

print "<META HTTP-EQUIV='Refresh' content='0;URL=members.php'>";
} else {
print "<META HTTP-EQUIV='Refresh' content='0;URL=memberlogin.php'>";
}

// Free the resources associated with the result set
// This is done automatically at the end of the script
mysql_free_result($result);
?>

It worked fine before the migration??? Anyone know where the problem is?

CORRECTION!! This is the userlogon page:

<?php
$link = mysql_connect('localhost:/tmp/mysql5.sock', 'db_user', 'db_pw');
if (!$link) {
   die('Could not connect: ' . mysql_error());
}

//mysql_close($link);

if (!mysql_select_db('db_name', $link)) {
   echo 'Could not select database';
   exit;
}


$username =  $HTTP_POST_VARS["username"];
$password =  $HTTP_POST_VARS["password"];
$member_id = '';
$role = '';
$firstname = '';

// Formulate Query
// This is the best way to perform a SQL query
// For more examples, see mysql_real_escape_string()

$query = sprintf("SELECT users.member_id, users.username, users.password, users.role, members.firstname FROM users join members on users.member_id = members.member_id WHERE users.username ='%s' AND users.password='%s'",
   mysql_real_escape_string($username),
   mysql_real_escape_string($password));

// Perform Query
$result = mysql_query($query);

// Check result
// This shows the actual query sent to MySQL, and the error. Useful for debugging.
if (!$result) {
   $message  = 'Invalid query: ' . mysql_error() . "\n";
   $message .= 'Whole query: ' . $query;
   die($message);
}

// Use result
// Attempting to print $result won't allow access to information in the resource
// One of the mysql result functions must be used
// See also mysql_result(), mysql_fetch_array(), mysql_fetch_row(), etc.
while ($row = mysql_fetch_assoc($result)) {

   $member_id = $row['member_id'];
   $username = $row['username'];
   $firstname = $row['firstname'];
    $role = $row['role'];

}

if ($member_id != ''){
session_start();

$_SESSION['membername'] = $username;
$_SESSION['username'] = $username;
$_SESSION['firstname'] = $firstname;
$_SESSION['memberid'] = $member_id;
$_SESSION['role'] = $role;

print "<META HTTP-EQUIV='Refresh' content='0;URL=members.php'>";
} else {
print "<META HTTP-EQUIV='Refresh' content='0;URL=memberlogon.php'>";
}

// Free the resources associated with the result set
// This is done automatically at the end of the script
mysql_free_result($result);
?>
