查询表单无效后自动发送电子邮件回复，'emailid'参数未定义？

Question

我需要在表单上添加自动回复电子邮件。

这要求我们在[cd-iframe]指令中添加一个参数，指定需要发送哪个电子邮件。这使我们可以控制不同页面和网站上的不同电子邮件模板。

我一直在尝试修改WordPress上的CD-CRM插件，以允许这个新参数（称为“emailid”）并将其传递给ASP（电子邮件实际将在那里发布）。不幸的是，我的成功有限。

我一直在使用http://www.royalliverbuildingvenue.co.uk/contact/作为我的测试页面，在进行更改之前要非常小心地备份所有内容。

以下是代码：

CD-CRM集成-ea.php

    <?php    
    // If this file is called directly, abort.
    if (!defined('WPINC')) {
        die;
    }         
    function my_scripts() {
      wp_register_script('analytics-cookie', plugins_url('/analytics-cookie.js', __FILE__), array('jquery'), 1.0, true);
      wp_register_style( 'cd-style', plugins_url('style.css', __FILE__) );

      wp_enqueue_style( 'cd-style' );
      wp_enqueue_script('analytics-cookie');
    }

    add_action( 'wp_enqueue_scripts', 'my_scripts' );         
    function cd_iframe_shortcode($atts)
    {         
        //Default values
        extract(shortcode_atts(array(
            'url' => 'https://secure.concertogroup.co.uk/forms/enquiry/vs.asp',
            'style' => 'width:100%;height:500px;',
            'stylesheet' => '',
            'pass_venue' => 0,
            'colour' => 0,
            'forecolour' => 0,
            'id' => 1,
            'thank_you' => 0,
            'subject' => 0,
            'emailid' => 0
        ), $atts));

        $refUrl = "{$_SERVER['HTTP_HOST']}{$_SERVER['REQUEST_URI']}";
        $escaped_url = htmlspecialchars($refUrl, ENT_QUOTES, 'UTF-8');
        $escaped_url = strtok($escaped_url, '?');

        $ref = $escaped_url;

        $prefix = $id;

        $iframeDiv = '<div id="iframeParent-'. $prefix .'" class="iframe-parent" data-id="'. $prefix .'"></div>';

        pw_load_scripts($ref, $url, $style, $stylesheet, $pass_venue, $colour, $forecolour, $id, $thank_you, $subject, $emailid);

        return $iframeDiv;
    }

    function pw_load_scripts($ref, $url, $style, $stylesheet, $pass_venue, $colour, $forecolour, $id, $thank_you, $subject, $emailid)
    {
        wp_register_script('pw-script', plugins_url('/script.js', __FILE__), array('jquery'), 1.2, true);
        wp_enqueue_script('pw-script');
        wp_localize_script('pw-script', 'pw_script_vars' . $id, array(
                'ref' => $ref,
                'url' => $url,
                'cssStyle' => $style,
                'stylesheet' => $stylesheet,

                'forecolour' => $forecolour,
                'id' => $id,
                'thank_you' => $thank_you,
                'subject' => $subject,
                'emailid' => $emailid
            )
        );
    }

    // Launch the plugin
    add_shortcode('cd_iframe', 'cd_iframe_shortcode');

的script.js

    function readCookie(name) {
        var nameEQ = name + "=";
        var ca = document.cookie.split(';');
        for(var i=0;i < ca.length;i++) {
            var c = ca[i];
            while (c.charAt(0)==' ') c = c.substring(1,c.length);
            if (c.indexOf(nameEQ) === 0) return c.substring(nameEQ.length,c.length);
        }
        return null;
    }

    function convertToSlug(Text) {
      if (Text !== '') {
        return Text
            .toLowerCase()
            .replace(/[^\w ]+/g,'')
            .replace(/ +/g,'-')
            ;
      } else {
        return '';
      }
    }

    function cdReturnIFrame(prefix) {

      var cookieValue = readCookie('first.session');

      var settingObj = window["pw_script_vars" + prefix];

      var venueName = '';
      var iframeUrl = settingObj.url + '?ref=' + settingObj.ref + '&stylesheet=' + settingObj.stylesheet + '&' + cookieValue;

      if (settingObj.pass_venue === "1") {
        venueName = jQuery( "#venue-title" ).text();
        venueName = convertToSlug(venueName);
        iframeUrl = iframeUrl + '&subject=' + venueName;
      }

      if (settingObj.thank_you !== "0") {
        iframeUrl = iframeUrl + '&thank_you=' + settingObj.thank_you;
      }

      if (settingObj.subject !== "0") {
        iframeUrl = iframeUrl + '&subject=' + settingObj.subject;
      }

      if (settingObj.colour !== "0") {
        iframeUrl = iframeUrl + '&colour=' + settingObj.colour;
      }

      if (settingObj.forecolour !== "0") {
        iframeUrl = iframeUrl + '&forecolour=' + settingObj.forecolour;
      }

      if (settingObj.emailid !== "0") {
        iframeUrl = iframeUrl + '&emailid=' + settingObj.emailid;
      }

      // Define
      var iframe = '<div class="iframe-container"><iframe allowfullscreen class="crm_form" frameborder="0" src=' + iframeUrl + ' style=' + settingObj.cssStyle + '></iframe></div>';

      jQuery('#iframeParent-' + prefix).append(iframe);
    }

    jQuery(document).ready(function($) {

      $('.iframe-parent').each(function( index ) {
          var id = $(this).data('id');
          cdReturnIFrame(id);
      });

    })

;

该插件现在在地址中创建了一个“＆amp; emailid =”参数，但该值始终为“未定义”（对我来说听起来像JS）。

我希望你能提供帮助，并期待收到你的回复。
