Question

PHP代码向我发送了来自服务器的电子邮件，但用户输入为空或“空白”。我只收到：“发件人：\电子邮件：\主题：\消息：”仅此而已。

如何修复我的PHP和/或HTML代码以接收来自表单的用户输入？这是我现有的HTML和PHP代码，不会从表单发送任何“用户输入”。

感谢任何可以提供帮助的人！

检查所有变量为空还是不像下面的代码一样，也使用pregmatch验证电子邮件地址

<?php

$errors = '';

$myemail = 'yourname@website.com';//<—–Put Your email address here. if(empty($_POST['name']) ||

empty($_POST['email']) ||

empty($_POST['message']))

{

$errors .= "\n Error: all fields are required”;

}

$name = $_POST['name'];

$email_address = $_POST['email'];

$message = $_POST['message'];

if (!preg_match(

"/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$/i”, $email_address))

{

$errors .= "\n Error: Invalid email address”;

}

if( empty($errors))

{

$to = $myemail;

$email_subject = "Contact form submission: $name";

$email_body = "You have received a new message. ".

" Here are the details:\n Name: $name \n ".

"Email: $email_address\n Message \n $message";

$headers = "From: $myemail\n";

$headers .= "Reply-To: $email_address";

mail($to,$email_subject,$email_body,$headers);

//redirect to the 'thank you' page

header('Location: contact-form-thank-you.html');

}

我希望这对您有用。

考虑这是您的表格

<form action="yourpage.php" method="post">
<input type="text" name="name" placeholder="enter name" required>

<input type="submit" name="submit" placeholder="enter name">

确保<form action=""链接到正确的页面，并且method="post"应该在此处。如果当前页面上有表单，即我的情况是yourpage.php，则将表单操作留空。另外，我建议在输入字段的末尾添加必填项，例如

<input type="text" name="name" placeholder="enter your name" required>

因为它迫使用户在其中写入一些值，所以您不会得到空值

接下来将是您的php文件，只需在第一行中添加代码

if(isset($_POST['submit'])) {

上面的代码验证用户单击了“提交”按钮，从而使总体代码看起来像

    <?php
if(isset($_POST['submit'])) {
    $name = $_POST['name'];
    $email = $_POST['email'];
    $phone = $_POST['phoneT'];
    $call = $_POST['call'];
    $website = $_POST['website'];
    $priority = $_POST['priority'];
    $type = $_POST[itypel];
    $message = $_POSTUmessagefl;
    $formcontent = "  From:$name \n  Phone: $phone \n  CallBack: $call \n Website: $website \n  Priority: $priority \n Type: $type \n  Message:    $message";
    $recipient = "YOUREMAIL@HERE.COM";
    $subject - "Contact  Form";
    $mailheader = "From:                 $email                     \r\n";
    mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");
    echo "Thank You!" . "           -" . "<a  href=iform.htmll
    style='text-decoration:none;color:#ff0099;'>  Return
    Home</a>";
}
?>

PHP的问题。我收到电子邮件，但没有网站的用户输入
