对于我的注册，我使用自定义注册表。它工作得很好。它发送带有用户名和密码的电子邮件。

我想生成url，这样当用户单击它时，它会自动完成激活。我不希望他们手动写入用户名或密码。我发送电子邮件的代码

                $random_password = wp_generate_password( 12, false );
            $status = wp_create_user( $username, $random_password, $email );
            if ( is_wp_error($status) ) 
                echo "Username already exists. Please try another one.";
            else {
                $from = get_option(\'admin_email\');
                $headers = \'From: \'.$from . "\\r\\n";
                $subject = "Registration successful";
                $msg = "Registration successful.\\nYour login details\\nUsername: $username\\nPassword: $random_password";
                wp_mail( $email, $subject, $msg, $headers );

                echo "Please check your email for login details.";
            }
