私はphpとmysqlを使用してログインページを作成していますが、電子メールとパスワードを入力して入力を送信すると、プロファイルページに移動せずにブラウザに空白のページが表示されます。
このエラーを修正する方法???
login.php
<?php
$message = "";
if(isset($_POST['email'])!="")
{
require_once('include/connect.php');
$email = $_POST['email'];
$pass = $_POST['pass'];
$email = strip_tags($email);
$pass = strip_tags($pass);
$email = mysql_real_escape_string($email);
$pass = mysql_real_escape_string($pass);
//$pass = md5($pass);
$firstname="";
$email="";
$sql=mysql_query( "SELECT user_id FROM user WHERE email_address='$email'AND password='$pass'LIMIT 1") or die("error in user table");
$login_check = mysql_num_rows($sql);
if($login_check > 0)
{
while($row = mysql_fetch_array($sql))
{
$id = $row['user_id'];
$_SESSION['user_id']= $id;
var_dump($id);
$firstname = $row['first_name'];
$_SESSION['first_name']= $firstname;
var_dump($firstname);
$email = $row['email'];
$_SESSION['email']= $email;
var_dump($email);
mysql_query("UPDATE user SET last_log_date=now() WHERE user_id='$id'");
header("Location: profile.php");
}//close while
}//close if
else
{
$message = "incorrect Email or Password!!";
exit();
}
}//close if
?>
