使用php发送电子邮件错误 - Sending email error using php

所以有一个单一的表单，它只获取个人的电子邮件并将其发送到我指定的电子邮件地址。但我想我写代码的方式不对，因为我有错误。我也看到过其他的堆叠流问题，但我不确定为什么这不起作用。这是html中的表单。

<form style="margin-bottom:50px;" name="contactform" action="contact-form-handler.php" class="news-letter "method="post">
  <div class="subscribe-hide">
    <input type="text" name="email" class="form-control"  placeholder="Email Address"  >
    <button  type="submit"  class="btn"><i class="fa fa-envelope"></i></button>
  </div><!-- /.subscribe-hide -->
</form><!-- /.news-letter -->

这是另一个文件中的PHP代码。

    <?php
$errors = '';
$myemail = 'masnadhossain@live.com';
   empty($_POST['email']))
{
    $errors .= "'n Error: all fields are required";
}
$email_address = $_POST['email'];
if (!preg_match(
"/^[_a-z0-9-]+('.[_a-z0-9-]+)*@[a-z0-9-]+('.[a-z0-9-]+)*('.[a-z]{2,3})$/i",
$email_address))
{
    $errors .= "'n Error: Invalid email address";
}
if( empty($errors))
{
$to = $myemail;
$email_subject = "Contact form submission";
$email_body = "You have received a new message. ".
" Here are the details:".
"Email: $email_address'n ";
$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');
}
?>

我得到的错误是服务器错误500

您的代码有语法错误，请检查。

第3行应为：

if (empty($_POST['email']))
{
    $errors .= "'n Error: all fields are required";
}

1。）您遇到的第一个问题是，您从通过邮寄输入的表单中发送电子邮件地址，但您没有使用它。

2.）To和From变量具有相同的电子邮件地址masnadhossain@live.com造成冲突

3.）用于检查电子邮件地址有效性的Preg_Match错误。我在下面重新编写了您的代码。

如果你从表单输入中发布用户电子邮件（如gmail、yahoomail等），这段代码会让你开始。

如果你想在代码中初始化电子邮件，只需更改

$email_address = strip_tags($_POST['email']);

可能是

$email_address = 'user1@gmail.com';

最后，From变量必须是指向您的网站地址的电子邮件地址。在这种情况下，我认为是masnadhossain@live.com

此代码正在工作。如果它能解决你的问题，请把它标记为正确答案。。。。

<?php

//Users email address coming from form input eg. gmail,yahoomail etc.
$email_address = strip_tags($_POST['email']);
//validate the email address
$email_val= filter_var($email_address, FILTER_VALIDATE_EMAIL);
if (!$email_val){
echo "<font color=red><b>Invalid Email Address</b></font>";
exit();
}

$to=$email_val;
$subject = "Contact form submission";
$message = "Here is the message;
// set the from variable to any email pointing to your website
$from = "masnadhossain@live.com";
$headers = "From:" . $from;
$sent=mail($to,$subject,$message,$headers);
 if($sent)  {
print "<br><font color=green><b>Your mail was sent Successfully</b></font>";
//redirect to the 'thank you' page
header('Location: contact-form-thank-you.html');
 } else  {
print "<br><font color=orange><b>We encountered an error sending your mail.</b></font>";
 }
?>
