Many times we face an issue regarding exclusive addition of a product in cart. For example, if a product say A is in cart then customer cannot add any new product B that is called exclusive products. In this case,\u00a0\u00a0customer is bound to either remove that very product A from cart or place order for it. So, here we will put some WooCommerce Cart Restriction.<\/p>\n

 <\/p>\n

WooCommerce Cart Restriction With ID<\/h3>\n

 <\/p>\n

Lets say a product named A is exclusive and we know it’s ID i.e., product id is known then we can approach like this:-<\/p>\n

<?php\r\n\r\nclass Exclusive_Product{\r\n\r\n\tfunction __construct(){\r\n\r\n\t\tadd_filter( 'woocommerce_before_cart', array($this, 'check_cart_product') ,10, 1);\r\n\r\n\t}\r\n\r\n\tpublic function check_cart_product( $cart_item_data ){\r\n\t\tglobal $woocommerce;\r\n\t\t$id; \/\/ exclusive product id\r\n                $cart<\/code> = WC()->cart;<\/code>\r\n\t\t$get_cart = WC()->cart->cart_contents; \/\/all cart contents\r\n\t\tif(!empty($get_cart)){\r\n\t\t\tforeach($get_cart as $key => $value ){\r\n\t\t\t\t$product_id = $value['product_id'];\r\n\t\t\t\tif($product_id == $id){ \/\/comparing exclusive product id i.e.\"$id\" with all cart products id's i.e.\"$product_id\"\r\n\t\t\t\t\t$woocommerce->cart->empty_cart();\r\n\t\t\t\t\tWC()->cart->add_to_cart($id);\r\n\t\t\t\t}\r\n\t\t\t}\r\n\t\t\treturn WC()->cart->cart_contents;\r\n\t\t}\r\n\t}\r\n\r\n}<\/pre>\n
As we can see WooCommerce already provides a filter named “woocommerce_before_cart” so we have to load our function on that very hook. The filter provides cart data, so we will get all cart data and \u00a0perform check for the exclusive product A with id “$id” among all products in cart. If the id’s matches then we will empty cart and add the exclusive product only in cart else we will do no changes in cart.<\/p>\n
 <\/p>\n
WooCommerce Cart Restriction With Title<\/h3>\n
 <\/p>\n
There is also a situation when we don’t know the id of exclusive product so in that case we can approach like this:-<\/p>\n
<?php\r\n\r\nclass Exclusive_Product{\r\n\r\n\tfunction __construct(){\r\n\r\n\t\tadd_filter( 'woocommerce_before_cart', array($this, 'check_cart_product') ,10, 1);\r\n\r\n\t}\r\n\r\n\tpublic function check_cart_product( $cart_item_data ){\r\n\t\tglobal $woocommerce;\r\n\t\t$exclusive_product = get_page_by_title('Product Name', OBJECT, 'product');\r\n\t\t$id = $exclusive_product->ID; \/\/ID of exclusive product\r\n                $cart<\/code> = WC()->cart;<\/code>\r\n\t\t$get_cart = WC()->cart->cart_contents; \/\/all cart contents\r\n\t\tif(!empty($get_cart)){\r\n\t\t\tforeach($get_cart as $key => $value ){\r\n\t\t\t\t$product_id = $value['product_id'];\r\n\t\t\t\tif($product_id == $id){ \/\/comparing exclusive product id i.e.\"$id\" with all cart products id's i.e.\"$product_id\"\r\n\t\t\t\t\t$woocommerce->cart->empty_cart();\r\n\t\t\t\t\tWC()->cart->add_to_cart($id);\r\n\t\t\t\t}\r\n\t\t\t}\r\n\t\t\treturn WC()->cart->cart_contents;\r\n\t\t}\r\n\t}\r\n\r\n}<\/pre>\n
I hope its quite easy to understand the above code. We can simply get the product details by using \u00a0get_page_by_title() and then we can ghet it’s ID.<\/p>\n
We also face some cases where we don’t know \u00a0id and title of custom post type. So, in such cases we can perform the same using “post type”.<\/p>\n
