更新：

我用另一个钩子得到了这个user_register. 看起来像是wpmu_activate_user从未触发。

I would still like to have this happen after the user verifies and sets a password though. Can anyone help?

Current Code:

function xxx_whmcs_signup($user_id) {
    
   //Get User Fields
    $user_info2 = get_userdata($user_id);
    $id = $user_info2->ID;

   //Get Custom Fields
    $first_name = get_field(\'first_name_c\', \'user_\'. $id );
    $last_name = get_field(\'last_name_c\', \'user_\'. $id );
    $address1 = get_field(\'address_1\', \'user_\'. $id );
    $city = get_field(\'city\', \'user_\'. $id );
    $state = get_field(\'state\', \'user_\'. $id );
    $postcode = get_field(\'postcode\', \'user_\'. $id );
    $country = get_field(\'country\', \'user_\'. $id );
    $phonenum = get_field(\'phone_number\', \'user_\'. $id );
    $email = $user_info2->user_email;
    $password = $user_info2->user_pass;
    

   // Set WHMCS API Details
    $whmcsUrl = "xxx";
    $apiusername = "xxx";
    $apipassword = "xxx";
    
   //Return Fields
    $postfields = array(
        \'username\'  => $apiusername, //WHMCS Username
        \'password\'  => $apipassword, //WHMCS Password
        \'action\'    => \'AddClient\', //WHMCS Action
        \'firstname\' => $first_name,
        \'lastname\'  => $last_name,
        \'password2\' => $password,
        \'email\'     => $email,
        \'address1\'  => $address1,
        \'city\'      => $city,
        \'state\'     => $state,
        \'postcode\'  => $postcode,
        \'country\'   => $country,
        \'phonenumber\' => $phonenum,
        \'responsetype\' => \'json\'
        );
        
    // Call the API
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $whmcsUrl . \'includes/api.php\');
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 30);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
    curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postfields));
    $response = curl_exec($ch);
    if (curl_error($ch)) {
        die(\'Unable to connect: \' . curl_errno($ch) . \' - \' . curl_error($ch));
    }
    curl_close($ch);
    
    // Decode response
    $jsonData = json_decode($response, true);
 
    
    // Dump array structure for inspection
    var_dump($jsonData);

    $file = fopen("wp-content/plugins/integrations/curloutput.txt", \'w+\');
    fwrite($file, $response);
    fclose($file);    
    }

add_action(\'user_register\',"xxx_whmcs_signup",10,1);

原始帖子：我目前正在尝试获取Wordpress注册过程中填充的字段，并将它们发布到另一个API。

我需要掌握的字段包括：

当我创建原始代码时，如果用户已经登录并转到特定页面，我会设法使其正常工作，但在注册过程中，我似乎无法让代码正常工作（可能必须在激活后进行，因为设置密码时就是这样）。

整个代码当前为：

pruned

由于这些字段位于高级自定义字段中，我还尝试了：

pruned

当脚本从页面上的短代码运行时，这一点非常有效，但由于用户在注册过程中没有登录，当然会遇到额外的障碍。我假设这取决于我可以通过钩子传递给函数的信息。

我不完全理解如何将变量传递给函数，也不完全理解如何返回$meta的输出，以便查看正在使用的内容，因此这可能是一项非常简单的任务（祈祷成功）。也有可能我没有使用正确/最好的挂钩？

提前感谢！
