密码是正确的，但我收到错误的密码错误

Question

继承我的剧本，无论我做什么，我都会收到不正确的密码，请帮忙！

<?php

$email = $_POST['email-field'];
$password = $_POST['password-field'];

if ($email&&$password){ 
   $connect = mysql_connect("xx","xx","xx") or die("Couldnt connect!");
   mysql_select_db(xx) or die("Couldnt find db");

   $query = mysql_query("SELECT * FROM users WHERE email='$email'");
   $numrows = mysql_num_rows($query); 
   if ($numrows!=0){
     while ($row = mysql_fetch_assoc($query)){
        $dbemail = $row['email'];
        $dbemail = $row['password'];
     }

  if ($username==$dbusername&&$md5password==md5($password)) {
      echo "You're in!";
  }else
      echo "Incorrect password";    
}
else
    die("That user doessnt exist!");
}
else
    die("Please enter a username and a password"); 

?>

Answer 1

$dbemail = $row['email'];
$dbemail = $row['password'];

你把这两个叫做dbemail。在if语句中，使用$ dbusername和$ md5password。

您应该将$ row ['email']更改为$ dbusername，将$ row ['password']更改为$ md5password。

$dbusername = $row['email'];
$md5password = $row['password'];

Answer 2

您从未定义$dbusername或$password。

Answer 3

你要分配dbemail两次而不是md5password。
