php, check if cart contains requirements - add coupon - php

Question

I am attempting to have php check if the cart has 2 items specified from an array before applying a free product and coupon. This specific example I've included is checking the price is over a certain amount. I have tried this because I could not get the two items to work.
function bbloomer_add_gift_if_sku_added_cart( $passed, $product_id, $quantity ) {
global $woocommerce;
$skuswithgift = array('SMWB-M23','001-SLW');
$giftsku = 'comb';
$coupon_code = 'combfree';
$product = wc_get_product( $product_id );
if ($product->get_sku() && in_array($product->get_sku(), $skuswithgift) && $woocommerce->cart->total > 26.00) {
WC()->cart->add_to_cart( wc_get_product_id_by_sku($giftsku) );
wc_add_notice( __( 'Hey there! As promised, you recieved a free comb with the purchase of two towels and we added it to your cart for you!', 'woocommerce' ), 'success' );
$woocommerce->cart->add_discount( $coupon_code );
}
else {
WC()->cart->remove_cart_item( wc_get_product_id_by_sku($giftsku) );
$woocommerce->cart->remove_coupon( $coupon_code );
}
return $passed;
}
add_filter( 'woocommerce_add_to_cart_validation', 'bbloomer_add_gift_if_sku_added_cart', 10, 3 );
Tried this and it's not working
function bbloomer_add_gift_if_sku_added_cart( $passed, $product_id, $quantity ) {
global $woocommerce;
$skuswithgift = array('SMWB-M23','001-SLW');
$giftsku = 'comb';
$coupon_code = 'combfree';
$product = wc_get_product( $product_id );
$total_towels = 0;
// Determine how many towels there are
// Loop through every cart item
foreach ( $woocommerce->cart->get_cart() as $cart_item ) {
$product = $cart_item['data'];
//$product = $cart_item;
// Is it in Gift SKUs
$is_towel = in_array($product->get_sku(), $skuswithgift);
if($is_towel){
// Add this quantity to the total towels
$total_towels += intval($cart_item['quantity']);
}
}
// Apply Discount
if ($total_towels <= 2) {
WC()->cart->add_to_cart( wc_get_product_id_by_sku($giftsku) );
wc_add_notice( __( 'Hey there! As promised, you recieved a free comb with the purchase of two towels and we added it to your cart for you!', 'woocommerce' ), 'success' );
$woocommerce->cart->add_discount( $coupon_code );
}
else {
WC()->cart->remove_cart_item( wc_get_product_id_by_sku($giftsku) );
$woocommerce->cart->remove_coupon( $coupon_code );
}
return $passed;
}
add_filter( 'woocommerce_add_to_cart_validation', 'bbloomer_add_gift_if_sku_added_cart', 10, 3 );

Try below code
add_action('woocommerce_add_to_cart_redirect','customeApplyCode');
function customeApplyCode()
{
global $woocommerce;
$items = $woocommerce->cart->get_cart();
$productSku = array();
foreach($items as $item => $values) {
// Retrieve WC_Product object from the product-id:
$product = wc_get_product( $values['product_id'] );
// Get SKU from the WC_Product object:
$productSku[] = $product->get_sku();
}
$skuswithgift = array('SMWB-M23','001-SLW');
$result=array_intersect($skuswithgift,$productSku);
if(count($result)>0)
{
//product id of free product
$product_id = 1312;
$woocommerce->cart->add_to_cart($product_id);
add_filter( 'woocommerce_product_needs_shipping', 'hide_shipping_when_free_is_available', 10, 2 );
}
}
function hide_shipping_when_free_is_available( $rates, $package ) {
return false;
}
