我正在一个具有用户个人资料的网站上工作，并且我设法完成了注册页面，一旦用户在那里激活了帐户，他们将有权登录。
基本上我写出了我的登录脚本，当我查看网站时，我有两个错误，它们真的很混乱 [错误 1]：注意：未定义的索引：C:\xampp\htdocs\mountain-bikers\index.php 中的 loginEmail第 160 行 [错误 2]：注意：未定义索引：请记住第 166 行的 C:\xampp\htdocs\mountain-bikers\index.php return_msg=no_good
这是登录php代码：
<?php
if ($_POST['loginEmail'] != "") {
include_once "includes/mysql_connection.php";
$loginEmail = $_POST['loginEmail'];
$loginPassword = $_POST['loginPassword'];
$loginRemember = $_POST['remember'];
$loginEmail = strip_tags($loginEmail);
$loginPassword = strip_tags($loginPassword);
$loginEmail = mysql_real_escape_string($loginEmail);
$loginPassword = mysql_real_escape_string($loginPassword);
$pass = md5($loginPassword);
//make query
$sql = mysql_query("SELECT * FROM users WHERE email='$loginEmail' AND password='$loginPassword' AND activated='1'");
$login_check = mysql_num_rows($sql);
if($login_check > 0){
while($row = mysql_fetch_array($sql)){
$id = $row["id"];
session_register('id');
$_SESSION['id'] = $id;
$firstname = $row["firstname"];
session_register('firstname');
$_SESSION['firstname'] = $firstname;
$email = $row["email"];
session_register('email');
$_SESSION['loginEmail'] = $email;
} // close while
// Remember Me Section Addition... if member has chosen to be remembered in the system
if($remember == "yes"){
setcookie("idCookie", $id, time()+60*24*60*60, "/"); // 60 days; 24 hours; 60 mins; 60secs
setcookie("firstnameCookie", $firstname, time()+60*24*60*60, "/"); // 60 days; 24 hours; 60 mins; 60secs
setcookie("emailCookie", $email, time()+60*24*60*60, "/"); // 60 days; 24 hours; 60 mins; 60secs
setcookie("passwordCookie", $password, time()+60*24*60*60, "/"); // 60 days; 24 hours; 60 mins; 60secs
}
$my_msg = "all_good";
print "return_msg=$my_msg&id=$id&firstname=$firstname";
} else {
$my_msg = "no_good";
print "return_msg=$my_msg";
exit();
}
}// close if post
?>
我也收到电子邮件和密码字段的未定义变量错误。value="<?php print "$loginEmail"; ?>"此外，每个字段中都有一个登录名。如果您需要 HTML，请询问。
