Hello, im very green to php and I am having trouble creating a simple log in script. Not sure why this is not working, maybe a mysql_query mistake? I am not receiving any errors but nothing gets updated in the members table and my error message to the user displays.  :confused: any help is appreciated! here is my php:

 

 

<?php

session_start();

 

$errorMsg = '';

$email = '';

$pass = '';

 

if (isset($_POST['email'])) {

$email = ($_POST['email']);

$pass = ($_POST['password']);

 

$email = stripslashes($email);

    $pass = stripslashes($pass);

$email = strip_tags($email);

$pass = strip_tags($pass);

 

if ((!$email) || (!$pass)) {

$errorMsg = '<font color="#FF0000">Please fill in both fields</font>';

}else {

include 'scripts/connect_db.php';

$email = mysql_real_escape_string ($email);

$pass = md5($pass);

 

$sql = mysql_query("SELECT * FROM members WHERE email='$email' AND password='$pass'");

 

$log_check = mysql_num_rows($sql);

 

if ($log_check > 0) {

    while($row = mysql_fetch_array($sql)) {

 

$id = $row["id"];

$_SESSION['id'];

$email = $row["email"];

$_SESSION['email'];

$username = $row["username"];

$_session['username'];

 

mysql_query("UPDATE members SET last_logged=now() WHERE id='$id' LIMIT 1");

 

}//Close while loop

echo "You are logged in";

    exit();

}

else {

$errorMsg = '<font color="#FF0000">Incorrect login data, please try again</font>';

}

 

 

    }

}

?>

 

 

 

and the form:

 

<?php echo $errorMsg; ?>

<form action="log_in.php" method="post">

Email:<br />

<input name="email" type="text" /><br /><br />

Password:<br />

<input name="password" type="password" /><br /><br />

<input name="myBtn" type="submit" value="Log In" />

</form>
