now when the user adds any data to the form, its no being updated and the following error shows up: 现在，当用户将任何数据添加到表单时，它不会被更新，并且会显示以下错误：
Notice: Undefined index: phone in C:\\xampp\\htdocs\\vendor\\profile.php on line 174
Warning: Cannot modify header information - headers already sent by (output started at C:\\xampp\\htdocs\\vendor\\profile.php:10) in C:\\xampp\\htdocs\\vendor\\profile.php on line 179
now the problem is not the error, the problem is why is my data not being added to the database, can anyone please tell me what's wrong with my code? 现在的问题不是错误，问题是为什么我的数据没有被添加到数据库中，谁能告诉我我的代码有什么问题吗？
(NB: I know this code is prone to SQL injections, am doing this for testing purpose) （注意：我知道此代码易于进行SQL注入，正在出于测试目的进行此操作）

update data is not working because you put input name value as cc-payment name="cc-payment" for all. 更新数据不起作用，因为您将所有输入名称值都设置为cc-payment name="cc-payment" 。 it should be unique of each input. 每个输入应该唯一。 as per your post request, it should be like this : 根据您的职位要求，应该是这样的：
exam : 考试：
<div class="form-group">
<label for="full_name_label" class="control-label mb-1">Full Name</label>
<input id="full_name_label" name="full_name" type="text" class="form-control" aria-required="true" aria-invalid="false" >
</div>
<div class="form-group has-success">
<label for="phone_label" class="control-label mb-1">Phone</label>
<input id="phone_label" name="phone" type="text" class="form-control" aria-required="true" aria-invalid="false" value="">
</div>
in php : you can get value 在php中：您可以获得价值
$fullname = $_POST['full_name'];
$email = $_POST['phone'];
Hope you understand. 希望你能理解。 : ) :)
