I have a Woocommerce site running Woocommerce Subscriptions plugin.

The site only has one simple subscription, limited to one per user. I want to allow the user to set their own start time and subscription frequency, based on selections made in a dropdown box added during the checkout process.

I have added the checkout fields correctly, and they are simple select boxes:

    <select name="frequency" id="choose_frequency">
       <option value="week">Weekly</option>
       <option value="2week">Fortnightly</option>
       <option value="monthly">Monthly</option>
    </select>

    <select name="start-date" id="sub_start_date">
        <option value="22 Apr 2021">Thursday, 22 April 2021</option>
        <option value="29 Apr 2021">Thursday, 29 April 2021</option>
        <option value="6 May 2021">Thursday, 6 May 2021</option>
    </select>

I need to get the value, convert it to the correct meta, and then update the subscription before it has been created.

I’ve tried to update the meta using woocommerce_checkout_update_order_meta:

//Update the order meta with custom fields values
add_action('woocommerce_checkout_update_order_meta', 'customise_checkout_field_update_order_meta');
function customise_checkout_field_update_order_meta($order_id){
    $subscriptions_ids = wcs_get_subscriptions_for_order( $order_id );
    foreach( $subscriptions_ids as $subscription_id => $subscription_obj ){
        update_post_meta($subscription_id, '_schedule_start',date('Y-m-d h:i:s',$_POST('sub_start_date')));
    }
}

and also tried wcs_create_subscription:

// set start subscription date on checkout page
add_action('wcs_create_subscription', 'cc_wcs_create_subscription');
function cc_wcs_create_subscription($subscription){
    $order_id = $subscription->order->id;
    $subscription_id = $subscription->get_id();
    if($subscription_id  && $_POST('sub_start_date')){
                update_post_meta($subscription_id, '_schedule_start',date('Y-m-d h:i:s',$_POST('sub_start_date')));
    }
}

… I’ve even tried updating the frequency with AJAX:

jQuery(document).on('change','select#choose_frequency',function(){
    var cur_val = jQuery(this).val();
    jQuery.ajax({
            type:'post',
            url:woocommerce_params.ajax_url,
            data:{'action':'cc_update_product_subscription','productid':1086,'cur_val':cur_val},
            success:function(result){
                jQuery(document.body).trigger("update_checkout");
            }
    });
});

// update subscription frequency on checkout page
add_action('wp_ajax_cc_update_product_subscription','cc_update_product_subscription');
add_action('wp_ajax_nopriv_cc_update_product_subscription','cc_update_product_subscription');
function cc_update_product_subscription(){
    if($_POST('cur_val') == 'week'){
        update_post_meta($_POST('productid'),'_billing_interval','1');
        update_post_meta($_POST('productid'),'_billing_period','week');        
    }
    if($_POST('cur_val') == '2week'){
        update_post_meta($_POST('productid'),'_billing_interval','2');
        update_post_meta($_POST('productid'),'_billing_period','week');
    }
    if($_POST('cur_val') == 'monthly'){
        update_post_meta($_POST('productid'),'_billing_interval','1');
        update_post_meta($_POST('productid'),'_billing_period','month');
    }
    
    die();
}

Nothing seems to be working. The checkout is still processing through to completion, but the subscription details are not updated to reflect those selected by the user. What am I doing wrong?
