This custom shortcode allows your users to convert their myCRED points into a WooCommerce coupon, in order to give themselves a discount or partial payment on their order. In order for this to work, you need to set an exchange rate between points and your store currency and select. Requires myCRED 1.6+ and WooCommerce 2.4+

@gabrielmerovingi when a user remove coupon from payment page price is updating but mycred point isn't. Because coupon is generated already. When a coupon removed, points should be earn again. This would be better I think. And adding an expire date automatically (Like 15 days or 30 days).

EDIT:

I've done this. Automatically adds expiry date to coupons:

Added after $balance = $mycred->number( $balance );:
$today = date('Y-m-d'); $exp_date = date('Y-m-d', strtotime($today. ' + 15 days'));
Change update_post_meta( $new_coupon_id, 'expiry_date', ''); to update_post_meta( $new_coupon_id, 'expiry_date', $exp_date);

Hello everyone who can help me? I would like to add to this code the possibility of restricting the use of the coupon to only those who created it? thanks..

When I use coupon at the checkout page, the payment gateway stuck and can't proceed purchase.
Anyone can help me?

hi
After reenter on page, coupon disappear. How to always show generate coupon? Or how send email with coupon to user?

Hi,

Great script! Does anyone know how to use several point types to exchange Total balance points for coupons?

Thanks!

Bonjour mes shortcode reste entre [ ] pourquoi que dois je faire cordialement

J ai mis le code en functions.php
[mycred_to_woo_coupon] sur ma page
j ai activer payer par mes points
rien ne se passe

Hi,
This is a great script!

May I know where or how do I set the requirements for user to convert?

1. limit the number of times to convert, to prevent user separate the cart to make purchase
2. the promo code to that particular user
3. set expiry date. and if once expired, the points will return back to the user

Thanks!

hey, great snippet! is it possible that this is only possible for a few specific products? maybe id = 111, 234 & 6096?
