Im创建了一个简单的登录/注册页面，其中包含了用户调节和引导wp，用于繁重的工作。

我可以将新用户添加到数据库中，并创建密码并对其进行哈希运算，但当我使用该帐户登录时，密码将不起作用。我被难住了。。。

有人看到我丢了什么吗？

require_once( ABSPATH . WPINC . \'/registration.php\' );
$user_pass = wp_generate_password();
$userdata = array(
  \'user_pass\' => $user_pass,
  \'user_login\' => esc_attr( $_POST[\'user_email\'] ),
  \'user_email\' => esc_attr( $_POST[\'user_email\'] ),
);

if( !$userdata[\'user_login\'] )
  $error .= __(\'An Email Address is required for registration.\', \'frontendprofile\');
elseif ( username_exists( $userdata[\'user_login\'] ) )
  $error .= __(\'Sorry, that Email Address is already in use for another account.\', \'frontendprofile\');
elseif ( !is_email( $userdata[\'user_email\'] ) )
  $error .= __(\'You must enter a valid Email Address.\', \'frontendprofile\');
elseif ( email_exists( $userdata[\'user_email\'] ) )
  $error .= __(\'Sorry, that Email Address is already for another account.\', \'frontendprofile\');

else{
  $new_user = wp_update_user( $userdata );
}
