HTML Check list with PHP

Here is my HTML and javascript validation. I used checklist to select the projects but i am getting the mails with only first element value of checkbox or not getting any thing. I will post PHP code also. I am working on this check list thing first time please help me to get this thing done.

jQuery(".form-js-contact").submit(function() {
    var thisform = jQuery(this);
    jQuery('.required-error', thisform).remove();
    var aname = jQuery("#aname").val();
    var amail = jQuery("#amail").val();
    var aphone = jQuery("#aphone").val();
    var acomments = jQuery("#acomments").val();
    var color = jQuery("#color").val();

    var psubject = jQuery("#psubject").val();

    var data = {
        'aname': aname,
        'amail': amail,
        'aphone': aphone,
        'acomments': acomments,
        'psubject': psubject,
        'color': color
    };
    if (aname == "") {
        jQuery("#aname").after('<span class="form-description required-error">Required field.</span>');
    } else {
        jQuery("#aname").parent().find('.required-error').remove();
    }
    if (amail == "") {
        jQuery("#amail").after('<span class="form-description required-error">Required field.</span>');
    } else {
        jQuery("#amail").parent().find('.required-error').remove();
    }
    if (aphone == "") {
        jQuery("#aphone").after('<span class="form-description required-error">Required field.</span>');
    } else {
        jQuery("#aphone").parent().find('.required-error').remove();
    }
    if (acomments == "") {
        jQuery("#acomments").after('<span class="form-description required-error">Required field.</span>');
    } else {
        jQuery("#acomments").parent().find('.required-error').remove();
    }



    if (aname != "" && amail != "" && aphone != "" && acomments != "") {
        jQuery.post("contact_us_contact.php", data, function(result) {
            if (result == "done") {
                thisform.prepend("<div class='alert-message success-contact'><p><strong>Thank you " + name + "!</strong> We'll be in touch real soon .</p></div>");
                jQuery("#aname").val("");
                jQuery("#amail").val("");
                jQuery("#aphone").val("");
                jQuery("#acomments").val("");

            }
        });
    }
    return false;
});

This is my HTML code

<form class="form-style form-js-contact" action="contact_us_contact.php" method="post">
                         <input type="hidden" name="psubject" id="psubject" value="Enquiry from Contact Page">

<input style=font-size:16px name=submit type=submit value="Send Enquiry" class="submit_buttom buttonColor" id="Main_Contact_Form"></div>
</form>

<?php
function clean_text($text = '') {
    $text = trim($text);
    $text = strip_tags($text);
    $text = addslashes($text);
    $text = htmlspecialchars($text);
    return $text;
}
if (!$_POST) {
    die();
} else {
    if (empty($_POST["aname"]) && empty($_POST["aphone"]) && empty($_POST["amail"]) && empty($_POST["acomments"])) {
        echo "all_empty";
    } else if (empty($_POST["aname"])) {
        echo "empty_name";
    } else if (empty($_POST["amail"])) {
        echo "empty_mail";
    } else if (empty($_POST["aphone"])) {
        echo "empty_phone";
    } else if (empty($_POST["acomments"])) {
        echo "empty_Comments";
    } else {

        $your_email = "my@domain";
        $aname      = clean_text($_POST["aname"]);
        $amail      = clean_text($_POST["amail"]);
        $aphone     = clean_text($_POST["aphone"]);
        $acomments  = clean_text($_POST["acomments"]);
        $wname      = $_POST['color'];
        $psubject   = clean_text($_POST["psubject"]);
        $subject    = "$psubject";



        $headers = "From: leads@domain.in";
        $msg     = "New Message \n\r";
        $msg .= "Name : \t $aname \r\n";
        $msg .= "Email : \t $amail \r\n";
        $msg .= "Phone : \t $aphone \r\n";
        $msg .= "Message : \t $acomments \r\n";

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

            $msg .= "You chose the following color(s): \r\n";
            $msg .= "<ul> \r\n";

            foreach ($wname as $color) {
                $msg .= "<li>" . $color . "</li>  \r\n";
            }

            $msg .= "</ul>";

        } // isset




        echo "done";
        $done = @mail($your_email, $subject, $msg, $headers);
    }
}
?>
