如何在woocommerce中为购物车创建自定义折扣 [英] How to create custom discount for the cart in woocommerce
问题描述
我正在 WooCommerce 中创建一个插件,但在向购物车/结帐页面添加自定义折扣时遇到了一个小问题.
I'm creating a Plugin in WooCommerce and have a small issue with adding custom discounts to the CART / CHECKOUT page.
如何在不创建优惠券的情况下将自定义折扣应用于购物车?假设我想在购物车页面上提供 5 美元的折扣.我怎样才能做到这一点?
How can I apply custom discount to the cart without creating coupons? Say I want to give some discount of 5 dollars on the cart page. How can I do that?
下面是我使用优惠券申请折扣的插件文件中的代码,但我想在不使用优惠券的情况下添加另一个自定义折扣.
Below is my code from the plugin file where I have used a coupon to apply discount, but I want to add another custom discount without the use of coupon.
插件文件中的动作钩子:
Action Hook in the plugin file :
add_action('woocommerce_calculate_totals',array(&$this,'cart_order_total_action'));
它在插件文件中的作用是:
and its function in the plugin file is :
public function cart_order_total_action(){
if ( is_user_logged_in() ){
global $woocommerce;
global $current_user;
global $wpdb;
$u_id = $current_user->ID;
$table_name = $wpdb->prefix."woocommerce_customer_reward_ms";
$thetable2 = $wpdb->prefix . "woocommerce_customer_reward_cart_ms";
$table_name3 = $wpdb->prefix."woocommerce_customer_reward_points_log_ms";
$data = $wpdb->get_row("SELECT * from $table_name where id=$u_id");
$data2 = $wpdb->get_row("SELECT * from $thetable2");
/* Order Id goes here */
$orders=array();//order ids
$args = array(
'numberposts' => -1,
'meta_key' => '_customer_user',
'meta_value' => $current_user->ID,
'post_type' => 'shop_order',
'post_status' => 'publish',
'tax_query'=>array(
array(
'taxonomy' =>'shop_order_status',
'field' => 'slug',
'terms' =>'on-hold'
)
)
);
$posts=get_posts($args);
$orders=wp_list_pluck( $posts, 'ID' );
$order = $orders[0];
/* Order Id ends here */
if($data){
$user_points = $data->points;
$points_set = $data2->woo_pts_set;
$coupon_code = 'wooreward_discount';
if($user_points>=$points_set){
// this following Code is optional and can be removed......as there is no need of if statement here
if ( $woocommerce->cart->has_discount( $coupon_code ) ) {
/*$woocommerce->add_error( __('Coupon Code Already Applied.!!','woocommerce'));*/
return false;
}else{
$woocommerce->cart->add_discount(sanitize_text_field($coupon_code));
$woocommerce->add_message( __('Taxco925 Reward Discount Applied.!!','woocommerce'));
}
}else{
$woocommerce->add_error( __('Not Enough Taxco925 Points.!!','woocommerce'));
}
}else{
$woocommerce->add_error( __('You have have not earned any Taxco925 Points yet.!!','woocommerce'));
}
}
}
正如你所看到的这一行 $woocommerce->cart->add_discount(sanitize_text_field($coupon_code));
将我的折扣添加到购物车中.但它在后台使用优惠券来这样做.有什么方法可以在不使用优惠券的情况下添加自定义折扣.
As you can see this line $woocommerce->cart->add_discount(sanitize_text_field($coupon_code));
adds my discount to the cart. But it uses coupon in the background to do so . Is there any way I can add a custom discount without the use of coupon.
推荐答案
add_action('woocommerce_checkout_order_processed','custom_disount',10,1);
function custom_disount($order_id){
$order = wc_get_order($order_id);
$order_items = $order->get_items();
foreach ($order_items as $order_item_key => $order_item) {
$product = new WC_Product((int) $order_item['product_id']);
$quantity = (int) $order_item['qty'];
$discount=($product->regular_price*30)/100; //30% disount.
wc_update_order_item_meta($order_item_key,'_line_total',($product->regular_price*$quantity)-($discount*$quantity));
}
}
