前篇老季写了WordPress 商城开发 WooCommerce 插件创建自定义产品类型Product_type 并在前端页面循环中隐藏，本文我们将记录一下，如何使用PHP或Javascript功能来实现添加到购物车功能。
Javascript
<script type="text/javascript"> function jwc_add_to_cart( product_id ) { if ( 'undefined' === typeof wc_add_to_cart_params ) { // The add to cart params are not present. return false; } var data = { product_id: product_id, quantity: 1, }; jQuery.post( wc_add_to_cart_params.wc_ajax_url.toString().replace( '%%endpoint%%', 'add_to_cart' ), data, function( response ) { if ( ! response ) { return; } // This redirects the user to the product url if for example options are needed ( in a variable product ). // You can remove this if it's not the case. if ( response.error && response.product_url ) { window.location = response.product_url; return; } // Remove this if you never want this action redirect. if ( wc_add_to_cart_params.cart_redirect_after_add === 'yes' ) { window.location = wc_add_to_cart_params.cart_url; return; } // This is important so your theme gets a chance to update the cart quantity for example, but can be removed if not needed. jQuery( document.body ).trigger( 'added_to_cart', [ response.fragments, response.cart_hash ] ); }); } </script>PHP
WC()->cart->add_to_cart( $product_id, $quantity );
