WooCommerce: Check if items are already in cart

Question

I found this great snippet from this website

The following is the function to check if a specific product exists in cart:

        function woo_in_ca         


        

Answer 1

There was a mistake in the woo_in_cart function. Here the correct one:

 function woo_in_cart($arr_product_id) {
    global $woocommerce;
    $cartarray=array();

    foreach($woocommerce->cart->get_cart() as $key => $val ) {
       $_product = $val['product_id'];
       array_push($cartarray,$_product);
    }

    if (!empty($cartarray)) {
       $result = array_intersect($cartarray,$arr_product_id);
    }

    if (!empty($result)) {
       return true;
    } else {
       return false;
    };

}

Here an example of usage:

//Set IDs Array variable

$my_products_ids_array = array(22,23,465);
if (woo_in_cart($my_products_ids_array)) {
  echo 'ohh yeah there some of that products in!';
}else {
  echo 'no matching products :(';
}
