I'd REALLY appreciate any assist with this.

I'm creating an e-card for customers to transmit for Valentine's day, and I must edit the code to ensure that I'm able to incorporate a check box that individuals can tick to be able to join our subscriber list.

When checked, I must send the shape to some specified current email address via Wordpress mail, because the wordpress plugin I'm using uses this technique. I've incorporated the code below:

SORRY To Add A Lot CODE However I Shouldn't MISS ANYTHING OUT

// email settings
$ecard_title = get_option('ecard_title');
$ecard_body_intro = get_option('ecard_body_intro');
$ecard_body_additional = get_option('ecard_body_additional');
$ecard_body_footer = get_option('ecard_body_footer');

if(isset($_POST['ecard_send'])) {
    if(get_option('ecard_captcha_display') == '1') {
        if($_POST['ecard_robot'] == 'spa') {
            $subject            = $ecard_title;
            $ecard_to           = $_POST['ecard_to'];
            $ecard_from         = $_POST['ecard_from'];
            $ecard_email_from   = $_POST['ecard_email_from'];
