Hello all!
I am trying to build a logout link on my session page. It does actually work but the problem is you have to click it twice forit to work?? The first time it is clicked it simply refreshes the page.
Here is the code:
session_start();
if(!isset($uid)) {
?>
<form method="get" action="index.php">
User ID:
<input type="text" name="uid">
Password:
<input type="password" name="pwd">
<input type="submit" value="Login">
</form>
<?php
exit;
}
session_register("uid");
session_register("pwd");
dbConnect("dbname");
$sql = "SELECT * FROM user WHERE
userid = '$uid' AND password = PASSWORD('$pwd')";
$result = mysql_query($sql);
if (!$result) {
error("A database error occurred");
}
if (mysql_num_rows($result) == 0) {
session_unregister("uid");
session_unregister("pwd");
?>
Your User ID or Password is incorrect.
</body>
</html>
<?php
exit;
}
$username = mysql_result($result,0,"fullname");
?>
<a href='index.php?logoff=true'>Logout</a>
<?php
if ($logoff=="true") {
session_unregister("uid");
session_unregister("pwd");
session_destroy();
}
?>
Its the link called logout that is the problem!
Is there anything I need to add to session_unregister("uid");, session_unregister("pwd"); or session_destroy(); to make it logout first time?
Thanks!
