Question

我的网站http://www.team2457.us/contact_us/sponsorship.php上有一个表单。我第一次填写表单它工作正常，PHP脚本做我想要的。但是现在每次加载页面时都会显示一个弹出窗口，表示表单已经成功完成，即使表单尚未加载，我甚至没有点击顶峰按钮。所以我想知道1）为什么它会像我点击顶峰按钮一样？ 2）为什么表单通过验证我使用？

这是我的代码：

                letter-spacing:2px;
            }
            form {
                margin:0 auto;
                width:459px;
            }
            input, textarea {

每次加载页面时都会调用您的邮件功能。您应该考虑在if（isset（））函数中放置处理$ _POST变量和mail函数的PHP逻辑，如下所示：

if(isset($_POST["name"])){
    //Code to handle input validation and email sending goes here
}

表单在页面加载空白和pa上提交
