Convert entries form to subscribers after submitting new from in Contact Form 7

Sometimes you’d like to store your contact’s data in the WP-SMS newsletter, so here is a simple function that helps you to do that.

/**
 * @param WPCF7_ContactForm $WPCF7_ContactForm
 */
function addNumberToSubscriberList($WPCF7_ContactForm)
{
    $name   = isset($_POST['your-name']) ? sanitize_text_field($_POST['your-name']) : "";
    $mobile = isset($_POST['your-mobile']) ? sanitize_text_field($_POST['your-mobile']) : "";

    if ($name and $mobile) {
        \WP_SMS\Newsletter::addSubscriber($name, $mobile, 'group-id');
    }
}
add_action('wpcf7_before_send_mail', 'addNumberToSubscriberList');

If you would like to make show the groups list on your form, first you need to create a dropdown field on Contact Form 7 which contains the Groups

[select group "1|News" "2|Sport" "3|General"]

Then you can access the group ID by $_POST['group']

**
 * @param WPCF7_ContactForm $WPCF7_ContactForm
 */
function addNumberToSubscriberList($WPCF7_ContactForm)
{
    $name   = isset($_POST['your-name']) ? sanitize_text_field($_POST['your-name']) : "";
    $mobile = isset($_POST['mobile-number']) ? sanitize_text_field($_POST['mobile-number']) : "";
    $group = isset($_POST['group']) ? sanitize_text_field($_POST['group']) : "";

    if ($name and $mobile) {
        \WP_SMS\Newsletter::addSubscriber($name, $mobile, $group);
    }
}

add_action('wpcf7_before_send_mail', 'addNumberToSubscriberList');
