PHP电子邮件脚本| 电子邮件未显示在收件箱中

Question

I have a very simple contact form like the one below that submits to a php script that is supposed to send an email to the one specified. But nothing is appearing in my inbox. I thought maybe it is just delayed but it has been about 3 hours now with nothing showing up!

Contact Form

<form name="contactform" id="contactForm" method="post" action="assets/send_form_email.php">
              <fieldset>
                <label for="name">Your Name</label>
                <input type="text" name="name" id="name" class="text ui-widget-content ui-corner-all" />
                <label for="email">Email</label>
                <input type="text" name="email" id="email" class="text ui-widget-content ui-corner-all" />
                <label for="question">Question/Comment</label>
                <textarea name="question" id="question" class="text ui-widget-content ui-corner-all" style="margin: 0px 0px 10px; width: 303px; height: 54px;"></textarea>
              </fieldset>
          </form>

* PHP Script *

   <? php
if (isset($_POST['email'])) {
    // EDIT THE 2 LINES BELOW AS REQUIRED
    $email_to = "";
    $email_subject = "New Contact Form | Website";
    echo $_POST['email'];
    echo $_POST['name'];
    echo $_POST['question'];

    function died($error) {
        // your error code can go here
        echo "We are very sorry, but there were error(s) found with the form you submitted. ";
        echo "These errors appear below.<br /><br />";
        echo $error."<br /><br />";
        echo "Please go back and fix these errors.<br /><br />";
        die();
    }
    // validation expected data exists
    if (!isset($_POST['name']) || !isset($_POST['email']) || !isset($_POST['question'])) {
        died('We are sorry, but there appears to be a problem with the form you submitted.');
    }
    $name = $_POST['name']; // required
    $email_from = $_POST['email']; // required
    $question = $_POST['question'];
    $error_message = "";
    $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
    if (!preg_match($email_exp, $email_from)) {
        $error_message. = 'The Email Address you entered does not appear to be valid.<br />';
    }
    $string_exp = "/^[A-Za-z .'-]+$/";
    if (!preg_match($string_exp, $name)) {
        $error_message. = 'The Name you entered does not appear to be valid.<br />';
    }
    if (strlen($question) < 5) {
        $error_message. = 'The Comments you entered do not appear to be valid.<br />';
    }
    if (strlen($error_message) > 0) {
        died($error_message);
    }
    $email_message = "Form details below.\n\n";

    function clean_string($string) {
        $bad = array("content-type", "bcc:", "to:", "cc:", "href");
        return str_replace($bad, "", $string);
    }
    $email_message. = "Name: ".clean_string($name)."\n";
    $email_message. = "Email: ".clean_string($email_from)."\n";
    $email_message. = "Question/Comment: ".clean_string($question)."\n";
    // create email headers
    $headers = 'From: '.$email_from."\r\n".'Reply-To: '.$email_from."\r\n".'X-Mailer: PHP/'.phpversion();@mail($email_to, $email_subject, $email_message, $headers); ?>
    <!--
    include your own success html here -->
    Thank you
    for contacting us.We will be in touch with you very soon. <? php
 } ?>

I really can not figure out what is wrong with the code to fix it. Someone please help.

Answer 1

Also be sure that mail() function works and there is no fail. Something like this:

if (mail($email_to, $email_subject, $email_message, $headers))
{
    echo 'Sent';
}
