       </label>
    </div>

PHP

<?php
                            // SUBSCRIBE TO MAILING LIST OPTION - ADD TO MAILCHIMP USING API
                            if ($_POST['emailUpdates'] == 'Yes')
                            {
                                // Include Mailchimp API class
                                require_once('MCAPI.class.php');
                                // Your API Key: http://admin.mailchimp.com/account/api/
                                $api = new MCAPI('feaf699f7a15c1ca27f6903152d4a3f1-us3');
                                // Your List Unique ID: http://admin.mailchimp.com/lists/ (Click "settings")
                                $list_id = "69010111da";
                                // Variables in your form that match up to variables on your subscriber
                                // list. You might have only a single 'name' field, no fields at all, or more
                                // fields that you want to sync up.
                                $merge_vars = array(
                                    'FNAME' => $_POST['first_name'],
                                    'LNAME' => $_POST['last_name']
                                );
                                // SUBSCRIBE TO LIST
                                if ( $api->listSubscribe($list_id, $_POST['email'], $merge_vars) === true ){
                                    $mailchimp_result = 'Success! Check your email to confirm sign up.';
                                } else {
                                    $mailchimp_result = 'Error: ' . $api->errorMessage;
                                }
                            }
                            ?>

在我的本地主机上，它写的是

注意:未定义的索引:emailUpdates在C:xampphtdocskinectapicontact.php第98行

我的代码有什么问题?任何帮助吗?

谢谢!

Answer 1

当你的表单submit name="emailUpdates"没有被检查，所以它返回这种类型的数组Undefined index: emailUpdates，意味着数组键不包含emailUpdates

。$_POST['emailUpdates']
