我正在使用OTP短信插件，该插件在woocommerce的签出和登录/注册页面上运行以下代码：

function smsalert_site_challenge_otp($user_login, $user_email, $errors, $phone_number=null,$otp_type,$password="",$extra_data=null,$from_both=false)
    {
        SmsAlertUtility::checkSession();
        $_SESSION[\'current_url\']    = SmsAlertUtility::currentPageUrl();
        $_SESSION[\'user_email\']     = $user_email;
        $_SESSION[\'user_login\']     = $user_login;
        $_SESSION[\'user_password\']  = $password;
        $_SESSION[\'phone_number_mo\']= $phone_number;
        $_SESSION[\'extra_data\']     = $extra_data;
        _handle_otp_action($user_login,$user_email,$phone_number,$otp_type,$from_both);
    }

function _handle_validate_otp_choice_form($postdata)
    {
        SmsAlertUtility::checkSession();
        if($postdata[\'mo_customer_validation_otp_choice\'] == \'user_email_verification\')
            smsalert_site_challenge_otp($_SESSION[\'user_login\'],$_SESSION[\'user_email\'],null,$_SESSION[\'phone_number_mo\'],"email",$_SESSION[\'user_password\'],$_SESSION[\'extra_data\'],true);
        else 
            smsalert_site_challenge_otp($_SESSION[\'user_login\'],$_SESSION[\'user_email\'],null,$_SESSION[\'phone_number_mo\'],"phone",$_SESSION[\'user_password\'],$_SESSION[\'extra_data\'],true);
