为什么这个 PHP 联系表不发送电子邮件？

Question

这是一个非常基本的问题，但我根本无法弄清楚。 提交此 PHP 表单时，它不会发送电子邮件，我不知道为什么。 我希望你们能帮忙。

<?php 
if($_POST['submit']){
    $to = "email@email.com";
    $from = $_POST['email'];
    $name = $_POST['name'];
    $subject = "Form submission";
    $message = $name . " wrote the following:" . "\n\n" . $_POST['message'];
    $headers = "From:" . $from;
    mail($to,$subject,$message,$headers);
    echo "Mail Sent. Thank you " . $name . ", we will contact you shortly.";
    header( 'Location: http://example.com' ) ;
    }
?>

    <container class="form">
      <table class="formtable" align="center">
        <form action="formcontact.php" method="post">
          <tr><td align="center" class="tabletitle">Name:</td></tr><tr class="space"><td align="center"><input type="text" name="name"></td></tr>
          <tr><td align="center" class="tabletitle">Email Address:</td></tr><tr class="space"><td align="center"><input type="text" name="email"></td></tr>
          <tr><td align="center" class="tabletitle">Message:</td></tr><tr class="space"><td align="center"><textarea rows="5" name="message" cols="30"></textarea></td></tr>
          <tr><td align="center"><input type="submit" name="submit" value="submit"></td></tr>
      </table>
    </container>

谢谢

Answer 1

在您的 HTML 文件中

表单动作=“”方法=“发布”

应该可以解决问题（当然，如果您将 HTML 包含在 php 中）

Answer 2

以这种方式检查：

<?php 
if($_POST['submit']){
    $to = "email@email.com";
    $from = $_POST['email'];
    $name = $_POST['name'];
    $subject = "Form submission";
    $message = $name . " wrote the following:" . "\n\n" . $_POST['message'];
    $headers = "From:" . $from;
     if(mail($to,$subject,$message,$headers)){
       echo "Mail Sent. Thank you " . $name . ", we will contact you shortly.";
       header( 'Location: http://example.com' ) ;
     }else
     {
            echo "Mail failed to Sent";
     }
}
?>
