Question

我有一个简单的表单，用户输入他们的电子邮件地址。他们之后应该通过以下代码收到消息：

$name = mysqli_real_escape_string($con, $_POST['jmeno']);
$surname = mysqli_real_escape_string($con, $_POST['prijmeni']);
$email = mysqli_real_escape_string($con, $_POST['email']);
$subject = "Subject";
$message = "Message text";

$sql="INSERT INTO kucharka (jmeno, prijmeni, email)
VALUES ('$name', '$surname', '$email ')";

mail($email,$subject,$message,"From: my@address.cz\n");

如果我将地址切换为固定的电子邮件，它可以正常工作。你能指点一下解决方案吗？我在那里看不到错误。

谢天谢地。

你可以这样做。电子邮件的两个变量。： -

$name = mysqli_real_escape_string($con, $_POST['jmeno']);
$surname = mysqli_real_escape_string($con, $_POST['prijmeni']);
$email_0 = $_POST['email'];
$email_1 = mysqli_real_escape_string($con, $_POST['email']);
$subject = "Subject";
$message = "Message text";

$sql="INSERT INTO `kucharka` (`jmeno`, `prijmeni`,`email`)
VALUES ('{$name}', '{$surname}', '{$email_1}')";

if(mail($email_0,$subject,$message,"From: my@address.cz\n"))
  echo "mail sent";
else
  echo "Error sending mail";

同时检查$ _POST [＆＃39; email＆＃39;]是否存在，正确的值来自使用POST方法的表单。

PHP mail（）函数不发送电子邮件
