无法将我的 php 页面重定向到我的 html 谢谢页面。 我究竟做错了什么？

Question

Here is my html code with my form. This file is named interested.html

 <h1 id="title5">Write Me</h1> <p align="center" style="font-size:20px">If you would like to get in touch with me, please do!</p> <form method="post" action="contact.php"> <fieldset> <input name="name" type="text" placeholder="Full Name"> <input name="email" type="email" placeholder="Email Address"> <textarea name="msg" placeholder="Your message..."></textarea> </fieldset> <input type="submit" class="Send"> </form>

This is my PHP code. After the form is filled out I want my thank you page (sent.html) to show instead of this page. This file is named contact.php

 <?php //redirect to thank you page //if information is not entered properly send to error page //submit an confirmation email to me $name = $_POST["name"]; $email = $_POST["email"]; $msg = $_POST["msg"]; echo "<pre>"; $email_body = ""; $email_body .= "Name " . $name . "\\n"; $email_body .= "Email " . $email . "\\n"; $email_body .= "Message " . $msg . "\\n"; echo $email_body; echo "</pre>"; header("location:sent.html"); ?>

Please help, and please let me know if I did not explain my question well enough or if more information is needed.

Thanks in advance!

Answer 1

Header instruction must be called before any content returned. But you write echo before header .

Answer 2

Try

<?php
ob_start();
//redirect to thank you page
//if information is not entered properly send to error page
//submit an confirmation email to me

  $name = $_POST["name"];
  $email = $_POST["email"];
  $msg = $_POST["msg"];

  echo "<pre>";
  $email_body = "";
  $email_body .= "Name " . $name . "\n";
  $email_body .= "Email " . $email . "\n";
  $email_body .= "Message " . $msg . "\n";
  echo $email_body;
  echo "</pre>";

  header("location:sent.html");

?>
