Question

表单仅在提交表单的用户使用.com电子邮件地址时才有效。如果用户使用的是.com地址，我会收到一封包含其表单信息（内容）的电子邮件。但是，如果有人使用其他电子邮件地址（例如.co.uk）提交表单，则不会向我发送电子邮件（billy@hotmail.co.uk），请提供帮助。 enquiry.php代码如下：

<?php
$email_to = "billy@hotmail.com";
$firstname = $_POST["firstname"];
$surname = $_POST["surname"];
$telephone = $_POST["telephone"];
$email = $_POST["email"];
$time = $_POST["time"];

if (empty($firstname)) {
     show_error("Please fill in your Name - hit back in the browser to correct");
}
if (empty($surname)) {
    show_error("Please fill in your Surname - hit back in the browser to correct");
}


if (empty($email)) {
    show_error("Please fill in your Email Address - hit back in the browser to correct");
}

if (empty($telephone)) {
    show_error("Please fill in your Telephone Number - hit back in the browser to correct");
}

if (empty($time)) {
    show_error("Please select a collection time slot - hit back in the browser to correct");
 }


 $email = htmlspecialchars($_POST['email']);
 if (!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/", $email)) {
     show_error("E-mail address not valid");
 }


 $email_from = $_POST["email"];
 $message = $_POST["message"];
 $email_subject = "Easter 2018 Order Form";
 $headers =
 "From: $email_from .\n";
 "Reply-To: $email_from .\n";
 $message = 

"First Name: ". $firstname . 
"\r\nSurname: " . $surname . 
"\r\nTelephone Number: " . $telephone . 
"\r\nEmail Address: " . $email . 
"\r\nTime Slot: " . $time . 


 ini_set("sendmail_from", $email_from);
 $sent = mail($email_to, $email_subject, $message, $headers, "-f"  
 .$email_from);
 if ($sent) {
     header("location: 
     http://www.billyfarroll.co.uk/thank-you.html");
 } else {
     echo "There has been an error sending your comments. Please try later.";
 }

function check_input($data, $problem='') {
   $data = trim($data);
   $data = stripslashes($data);
   $data = htmlspecialchars($data);
   if ($problem && strlen($data) == 0) {
      show_error($problem);
   }
   return $data;
}

function show_error($myError) {
?>

好的问题出在你的正则表达式上。

当你使用这个正则表达式

时

([\w\-]+\@[\w\-]+\.[\w\-]+)

它会匹配这类地址邮件的结果

billy@hotmail.co.uk

但匹配的结果将是

billy@hotmail.co

因为你要求a_word@a_word.a_word

因此，电子邮件地址根据您的代码有效，但不存在

你必须重新检查你的正则表达式。

也许试试

("/.*@.*\..*/")

enquiry.php表单仅适用于.com电子邮件地址
