Auto apply coupon based on total spent in shop woocommerce - php

Question

I need to apply a previously created coupon in woocommerce cart based on total spent in shop by logged in users. Example, If user already spent $300 or more in previous orders, in the next order, automatically apply "xxx" coupon.
based on "Apply automatically a coupon based on specific cart items count in Woocommerce" answer thread, that is what I have so far:
add_action( 'woocommerce_before_calculate_totals', 'auto_add_coupon_based_on_cart_items_count', 25, 1 );
function auto_add_coupon_based_on_cart_items_count( $user_id, $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
// Setting and initialising variables
$coupon = 'descuentolealtad'; // <=== Coupon code
$matched = false;
$customer = new WC_Customer( $user_id );
if( $customer->get_total_spent >= 60 ){
$matched = true; // Set to true
}
// If conditions are matched add coupon is not applied
if( $matched && ! $cart->has_discount( $coupon )){
// Apply the coupon code
$cart->add_discount( $coupon );
// Optionally display a message
wc_add_notice( __('Descuento de Lealtad aplicado'), 'notice');
}
// If conditions are not matched and coupon has been appied
elseif( ! $matched && $cart->has_discount( $coupon )){
// Remove the coupon code
$cart->remove_coupon( $coupon );
// Optionally display a message
//wc_add_notice( __('Descuento de Lealtad removido'), 'error');
}
}
I'm trying to use the dedicated get_total_spent() function from woocommerce but is giving me a blank screen.
Any help is appreciated.
Edit
That is my working code very different as I am using a negative fee:
add_action('woocommerce_cart_calculate_fees' , 'discount_based_on_customer_orders', 10, 1);
function discount_based_on_customer_orders( $cart_object ){
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
// Getting "completed" customer orders
$customer_orders = get_posts( array(
'numberposts' => -1,
'meta_key' => '_customer_user',
'meta_value' => get_current_user_id(),
'post_type' => 'shop_order', // WC orders post type
'post_status' => 'wc-completed' // Only orders with status "completed"
) );
// Orders count
$customer_orders_count = count($customer_orders);
// The cart total
$cart_total = WC()->cart->get_total(); // or WC()->cart->get_total_ex_tax()
// First customer order discount
if( empty($customer_orders) || $customer_orders_count == 0 ){
$discount_text = __('Loyalty Discount', 'woocommerce');
$discount = -7;
}
}

Updated - There is many mistakes in your code like:
For this hook there is only one variable argument: $cart… and not $user_id and $cart
Since Woocommerce 3, use the method get_total_spent() and not the property get_total_spent.
You should first check that user is logged in too.
Use the following revisited code instead:
add_action( 'woocommerce_before_calculate_totals', 'auto_add_coupon_based_on_total_spent', 10, 1 );
function auto_add_coupon_based_on_total_spent( $cart ) {
if ( ( is_admin() && ! defined( 'DOING_AJAX' ) ) || ! is_user_logged_in() )
return;
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
// Setting and initialising variables
$coupon = 'summer'; // <=== Coupon code
$spent_amount = 60;
$customer = new WC_Customer(get_current_user_id());
// If conditions are matched add coupon is not applied
if( $customer->get_total_spent() >= $spent_amount && ! $cart->has_discount( $coupon )){
// Apply the coupon code
$cart->add_discount( $coupon );
// Optionally display a message
wc_add_notice( __('Descuento de Lealtad aplicado'), 'notice');
}
// If conditions are not matched and coupon has been appied
elseif($customer->get_total_spent() < $spent_amount && $cart->has_discount( $coupon )){
// Remove the coupon code
$cart->remove_coupon( $coupon );
}
}
Code goes in function.php file of your active child theme (or active theme). It should better works.
