Integrate with Contact Form 7

Bin Opt-In works best with contact form seven. To integrate it into your contact forms, you need to add custom code like this to your theme functions.php.

add_action('wpcf7_before_send_mail', 'bin_opt_in_contact');
function bin_opt_in_contact($cf7)
{
    // Get current form id
    $formId = $cf7->id;

    // Array of form ids
    $forms = [159, 454];

    // Only apply to certain forms
    if(in_array($formId, $forms))
    {
        // Dont do anything if class is missing
        if(class_exists('BinOptIn'))
        {
            // At least, the email must be present
            if(is_email($_POST['email']))
            {
                // map salutation
                $salutationMap = [ 
                    'Frau' => 0,
                    'Madame' => 0,
                    'Mrs' => 0,
                    'Herr' => 1,
                    'Monsieur' => 1,
                    'Mr' => 1,
                    '*' => 2
                ];

                // assign form data with corresponding meta fields
                $postdata = [];
                $postdata['email'] = sanitize_email($_POST['email']);
                $postdata['first_name'] = sanitize_text_field($_POST['first_name']);
                $postdata['last_name'] = sanitize_text_field($_POST['last_name']);
                $postdata['salutation'] = $salutationMap[$_POST['salutation']];
                $postdata['terms_and_conditions_accepted'] = isset($_POST['terms_and_conditions_accepted']) ? 'yes' : '';

                // save contact
                BinOptIn::optIn($postdata, [
                    'opt_in_admin_message' => false,
                    'double_opt_in' => false,
                    'admin_unlock' => false,
                    'unlock_message' => false
                ]);
            }
        }
    }
}

Integrate with Contact Form 7 Multi-Step Pro

Save form data at every step by using the filter wpcf7_validate.

add_filter('wpcf7_validate', 'save_contact_step', 10, 2);
function save_contact_step($result, $tags)
{
    // Get current form id
    $formId = $_POST['_wpcf7'];

    // Array of form ids
    $forms = [159, 454];

    // Only apply to certain forms
    if(in_array($formId, $forms))
    {
        // Dont do anything if class is missing
        if(class_exists('BinOptIn'))
        {
            // save contact info here
            // BinOptIn::optIn()
        }
    }

    return $result;
}
