Here is the PHP to run the form:

<?php

if(!empty($_POST['check_list'])){
// Loop to store and display values of individual checked checkbox.
foreach($_POST['check_list'] as $selected){
echo $selected."</br>";
}}}

$doors = filter_var($_POST['doors'], FILTER_SANITIZE_STRING);

$site_owners_email = 'email@gmail.com'; // Replace this with your own email address

$site_owners_name_from = 'Free Estimate Submission';

if (strlen($firstname) < 2) {
    $error['firstname'] = "Please enter your first name";
}

if (strlen($lastname) < 2) {
    $error['lastname'] = "Please enter your last name";
}

if (!preg_match('/^[a-z0-9&\'\.\-_\+]+@[a-z0-9\-]+\.([a-z0-9\-]+\.)*+[a-z]{2}/is', $email)) {
    $error['email'] = "Please enter a valid email address";
}

if (strlen($phone) < 3) {
    $error['phone'] = "Please enter your phone number.";
}

if (!$error) {

    require_once('phpMailer/class.phpmailer.php');
    $mail = new PHPMailer();

    $mail->From = $email;
    $mail->FromName = $site_owners_name_from;
    $mail->Subject = "Form Submission";
    $mail->AddAddress($site_owners_email, $site_owners_name);
    $mail->IsHTML(true);
    $mail->Body = 'The estimate form on your website, 3Msecurityfilm.com, has been filled out.'. '<br/><br/>'. '<b>Company:</b> '. $company . '<br/><b>First Name:</b> '. $firstname .

    $mail->Send();

    echo "<div class='alert alert-success'  role='alert'>Thanks " . $firstname . ". Your message has been sent.</div>";

} # end if no error
else {

    $response = (isset($error['firstname'])) ? "<div class='alert alert-danger'  role='alert'>" . $error['firstname'] . "</div> \n" : null;

The code

// Loop to store and display values of individual checked checkbox.
foreach($_POST['check_list'] as $selected){
    echo $selected."</br>";
}

seems a bit odd to me. This displays all the values all right, but does not store them. After this loop, $selected will have as value the last element of the array. So, nothing is stored , what the comment suggests.

In the body of your mail, you're using $selected . This has some arbitrary value from the array, or is uninitialised if the array was empty. What you could do instead is implode(', ', $_POST['check_list']) , which joins the elements of the array with commas in between (ie [4,7,8] becomes "4, 7, 8" ).

If that still doesn't work, the value isn't properly passed into $_POST . You could do a var_dump($_POST) in the top of your file to see if the check_list values actually appear there. You can include the output of that var dump in your question if you need help with it.
