PHP邮件功能if语句

 

因此，当不发送邮件时，它可以在屏幕上显示失败消息

 

<?php 

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

    $to = "Test@gmail.com"; // this is your Email address

    $from = $_POST['email']; // this is the sender's Email address

    $first_na = $_POST['first_name'];

    $last_nae = $_POST['last_name'];

    $subject = "Form submission";

    $subject2 = "Copy of your form submission";

    $message = $first_name . " " . $last_name . " wrote the following:" . "\n\n" . $_POST['message'];

    $message2 = "Here is a copy of your message " . $first_name . "\n\n" . $_POST['message'];

    $headers = "From:" . $from;

    $headers2 = "From:" . $to;

    

mail($to,$subject,$message,$headers);

    

    

    mail($from,$subject2,$message2,$headers2); // sends a copy of the message to the sender

    echo "Mail Sent. Thank you " . $first_name . ", we will contact you shortly.";

    // You can also use header('Location: thank_you.php'); to redirect to another page.

    // You cannot use header and echo together. It's one or the other.

}

?>

 

答：如果要在失败时显示消息，则需要使用如下所示的邮件功能。if（mail（$ to，$ subject，$ message，$ headers））{回显'已发送邮件'; } else {echo'邮件未发送'; }
