我想要做的是删除加密我的数据库中的用户密码的md5加密。我设法删除了加密，但是在我删除它后，用户即使使用它也无法登录到他们的帐户他们正确的用户名和密码所以我认为我错过了一些东西。
这是我做的：
我替换了这个
return md5(md5($salt).$password);
有了这个
return $password;
并且
if(salt_password(md5($password), $user['salt']) == $user['password'])
使用
if(salt_password($password, $user['salt']) == $user['password'])
这些代码来自inc / functions_user.php文件

在我的inc / datahandlers / user.php文件中，我替换了这个
$user['md5password'] = md5($user['password']);
有了这个
$user['md5password'] = $user['password']
我无法在此处发布user.php代码，因为很遗憾，但是这里有一个链接：http://pastebin.com/p4rVPcVM
如果有人有时间查看这些代码并告诉我我做错了什么，我会非常感激。谢谢！
