Gravity Forms 上的预填字段

如何解决Gravity Forms 上的预填字段

我想使用去年的信息预先填写 2021 学年的注册表，并向所有家长发送邀请。 为所有需要的字段打开了所有“允许预填充”的表单。预填充字段名称为“pf”和管理员名称。 我尝试给自己发送一封电子邮件，其中包含包含预填充字段 = 去年数据的 URL。 显而易见的问题是安全性，因为链接包含个人信息。所以这行不通。

接下来我编写了一个 php 函数（我最初在开发过程中将数据放入一个数组中），它将读取我服务器上包含个人信息的 csv 文件。 我将它作为插件安装到 Gravity 表单中。不幸的是，我对 php 函数不够熟悉，所以我无法过滤掉对该函数的无关调用。它只需要为特定的表单 ID 运行。另外，我看不懂Gravity forms文档中关于子功能的部分，所以每次点击网站都跑，炸了网站。

我的计划是发送一封包含帐号和密码的电子邮件，登录后，该功能将运行并为该客户预填字段。

我将不胜感激此功能或预填充字段的更好方法的帮助。 感谢您的帮助。

代码如下：

<?php

// for testing
$account = 'B-613048';

$data_array = Array(
Array("pfAccountNumber","B-613001","B-613002","B-613003","B-613004","B-613005","B-613006","B-613007","B-613008","B-613009","B-613010","B-613011","B-613012","B-613013","B-613014","B-613015","B-613016","B-613017","B-613018","B-613019","B-613020","B-613021","B-613022","B-613023","B-613024","B-613025","B-613026","B-613027","B-613028","B-613029","B-613030","B-613031","B-613032","B-613033","B-613034","B-613035","B-613036","B-613037","B-613038","B-613039","B-613040","B-613041","B-613042","B-613043","B-613044","B-613045","B-613046","B-613047","B-613048","B-613049","B-613050","B-613051","B-613052","B-613053","B-613054","B-613055","B-613056","B-613057","B-613058","B-613059","B-613060","B-613061","B-613062","B-613063","B-613064","B-613065","B-613066","B-613067","B-613068","B-613069","B-613070","B-613071","B-613072","B-613073","B-613074","B-613075","B-613076","B-613077","B-613078","B-613079","B-613080"),Array("pfLastYear","Yes","Yes"),Array("pfPG1Prefix","Mrs.","Ms.","","Mr.","Dr.","")
);

$num_rows=count($data_array,0);
$num_cols=(count($data_array,1)-$num_rows)/$num_rows;

echo "num_rows= ".$num_rows."</br>";
echo "num_cols= ".$num_cols."</br>";

for ($f = 0; $f < $num_cols;$f++){$fields[$f] = $data_array[0][$f];}

for($c = 0; $c < $num_cols; $c++) {

    if($account == $data_array[0][$c]){
    
        for ($r = 0; $r < $num_rows;$r++){
            $account_data[$r] = $data_array[$r][$c];
            $filter = 'gform_field_value_'.$fields[$r];
            add_filter( $filter,'populate_function' );
                    function populate_function() {
                return $account_data[$r];
            };
        }
        break;
    };
}

?>
<?php
    function populate_function($g) {
        echo "g= ".$g;
        return $account_data[$g];
};
?>

解决方法

我建议使用 gravity_form 函数，该函数允许您传递动态填充参数键的数组及其要填充的相应值。

此外，如果您不想在访问表单之前要求登录，您可以为每个用户分配一个唯一 ID，该 ID 将被定义为 URL 参数以识别和检索所需的字段数据。

例如：

1. www.school.com/signup/?user=unique_complex_user_identier
2. 以重力形式击中模板
3. 读取并解码 URL 参数以识别相应用户，否则失败。
4. 传递到表单中的用户数据
