Question

我正在尝试实现一个联系表单，表单没有错误并且运行tnx到shank :)但是这个表单怎么会不会重定向到其他页面而是重新加载页面，如果所有字段都已提交到表单将刷新并有一个新的形式:) tnx请帮我，我在输入上添加了一些必要的功能。以及如何使用xampp

将其连接到mysqli数据库

contact.php：

   <?php
   $dbhost = "localhost";
   $dbuser = "root";
   $dbpass = "ntf123";
   $db = "ntfcatering";
   $conn = mysqli_connect($dbhost,$dbuser,$dbpass,$db);
  ?>

如何解决此问题？

Answer 1

基本程序流程如下：当提交表单时，调用服务器调用你的php程序。您的php程序必须获取用户输入表单的数据，将其放入数据库，然后将表单发回给您。 Mailer.php需要一些工作，从它的外观来看相当多，但你有一个良好的开端。
