将PHP代码与联系人表单7字段集成在一起

Question

我想得到contact-form-7字段的值，并将它们存储到PHP变量中。我要做一个预订表单，在其中我有两个选择类别，基于此，我想减少变量的值。

我打开联系人表单-7代码和目录，但没有得到文件的存储位置。我的WordPress预订看上去

下面是PHP代码示例

<?php
$cow = 100;
$goat = 200;
if (isset($_POST['cow']) || isset($_POST['goat'])) {
if(isset($_POST['cow'])){
    $cowSelect = $_POST['cow'];
    switch ($cowSelect) {
        case '1':
          $cow = ($cow - $_POST['cow']);
          echo 'Total ' .$cow. ' cows remaning'.'<br/>';
          break;
        case '2':
          $cow = ($cow - $_POST['cow']);
          echo 'Total ' .$cow. ' cows remaning'.'<br/>';
          break;
        case '3':
          $cow = ($cow - $_POST['cow']);
          echo 'Total ' .$cow. ' cows remaning'.'<br/>';
          break;
        case '4':
          $cow = ($cow - $_POST['cow']);
          echo 'Total ' .$cow. ' cows remaning'.'<br/>';

我制作了PHP代码示例，但是我想要WordPress联系人-表单-7的相同工作，帮助我如何将PHP与contact-7集成？或者如何获得contact-form-7值来完成与PHP代码相同的工作？

Answer 1

你会想看看联系表格7提供的钩子。您将链接到响应，以输出所需的内容。

至于下拉列表，您可以使用提供的选项在联系人表单7表单编辑器中创建它们。

您可以在http://hookr.io/plugins/contact-form-7/5.1.3/hooks/#index=a上看到一个钩子列表(对于CF7的最新版本)，您可能希望类似于wpcf7_ajax_json_echo钩子那样的东西来修改返回给用户的出站响应。下面是一个例子：

类似这样的东西(未经测试)，但是它会出现在wp-content/themes/footheme/function s.php(主题，函数文件)中。

add_filter('wpcf7_ajax_json_echo', function( $response, $result )
{
    $cow  = 100;
    $goat = 200;

    if (isset($response['cow']) || isset($response['goat'])) {
        if (isset($response['cow'])) {
            $cowSelect = $response['cow'];
            $cow = ($cow - $response['cow']);

            switch ($cowSelect) {
                case '1':
                case '2':
                case '3':
                case '4':
                case '5':
                    $message .= 'Total '.$cow.' cows remaning'.'<br/>';
                    break;
            }
        }

        if (isset($response['goat'])) {
            $goatSelect = $response['goat'];
            $goat = ($goat - $response['goat']);

            switch ($goatSelect) {
                case '1':
                case '2':
                case '3':
                case '4':
                case '5':
                    $message .= 'Total '.$goat.' goats remaning'.'<br/>';
                    break;
            }
        }
    }

    return $response;
}, 10, 2);

然后，您只需要创建一个下拉列表与您想要的选项，使下拉要求(如果需要的话)在联系表格7形式编辑器。

[select cows "1" "2" "3"]
