Question

我必须验证表格并发送电子邮件..我从w3schools复制此表格并附上mailto功能。但我不知道如何显示＆＃34;感谢您提交＆＃34;表单处理完毕后。请帮助..感谢信息应显示在提交按钮下方的同一页面上。

这是我的代码..

<!DOCTYPE HTML> 
<html>
    <head>
        <style>
            .error {color: #FF0000;}
        </style>
    </head>
    <body> 

    <?php
    // define variables and set to empty values
    $nameErr = $emailErr = $genderErr = $websiteErr = "";
    $name = $email = $gender = $comment = $website = "";

    if ($_SERVER["REQUEST_METHOD"] == "POST") {
       if (empty($_POST["name"])) {
         $nameErr = "Name is required";
       } else {
         $name = test_input($_POST["name"]);
         // check if name only contains letters and whitespace
         if (!preg_match("/^[a-zA-Z ]*$/",$name)) {
           $nameErr = "Only letters and white space allowed"; 
         }
       }

       if (empty($_POST["email"])) {
         $emailErr = "Email is required";
       } else {
         $email = test_input($_POST["email"]);
         // check if e-mail address is well-formed
         if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
           $emailErr = "Invalid email format"; 
         }
       }

       if (empty($_POST["website"])) {
         $website = "";
       } else {
         $website = test_input($_POST["website"]);
         // check if URL address syntax is valid (this regular expression also allows dashes in the URL)
         if (!preg_match("/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-z0-9+&@#\/%=~_|]/i",$website)) {
           $websiteErr = "Invalid URL"; 
         }
       }

       if (empty($_POST["comment"])) {
         $comment = "";
       } else {
         $comment = test_input($_POST["comment"]);
       }

       if (empty($_POST["gender"])) {
         $genderErr = "Gender is required";
       } else {
         $gender = test_input($_POST["gender"]);
       }
    }

    function test_input($data) {
       $data = trim($data);
       $data = stripslashes($data);
       $data = htmlspecialchars($data);
       return $data;
    }


    ?>

Answer 1

这很简单;

if(isset($email)){
   echo 'Success! Thanks for submitting';
}

然后将它放在邮件功能之后？请注意，您可以将$ email更改为您想要的任何POST变量，还可以更改echo内容。（如果你想将它放在表单内部，请记住将其包装在

中

<?php ?>

Php谢谢你在同一页面的消息
