過去一年中客戶購買產品的次數

Question

woocommerce如何檢查最近一年產品價格爲0時顧客購買產品的次數。爲了達到這個目的，我嘗試了下面的代碼並單獨得到答案，結果並不是按產品名稱或ID來縮短。請幫助我如何縮短它們。

這裏是

//Check if bought it in last one year and the number of quantity 
function customer_bought_qty(){ 

    //get the value of targeted product 
    $_options = get_option('license_page_option_name'); 
    $ex_product_ids = $_options['ex_product_ids_warranty']; 
    $target_products = explode(",",$ex_product_ids); //array(18,63,85) 


    // Get all customer orders 
    $customer_orders = get_posts(array(
     'numberposts' => -1, 
     'meta_key' => '_customer_user', 
     'meta_value' => get_current_user_id(), 
     'post_type' => 'shop_order', // WC orders post type 
     'post_status' => 'wc-completed', // Only orders with status "completed" 
     'date_query' => array(
       array(
        'column' => 'post_date_gmt', 
        'after' => '1 year ago', 
       ) 
      ) 
     )); 

    // Going through each orders for current customer 
    foreach ($customer_orders as $customer_order) { 
     $order = wc_get_order($customer_order); 
     $order_id = $order->id; 
     $items = $order->get_items(); 
     $subtotal = $order->get_subtotal(); //to check how many free item bought 

    //Loop trough the order items and see if it is a product we need to cehck 
     foreach($items as $item) {   
      if($subtotal== 0 && in_array($item['product_id'], $target_products)) { 
       $_product_id = $item['product_id']; 
       $_product_qty = $item['qty']; 
       if(isset ($_product_id)){ 
        echo '('. get_the_title($_product_id). ')# You bought '.$_product_qty.' Times<br>'; 
       } 
      } 
     } 
    } 

} 

輸出看起來

(Product 2)# You bought 1 Times 
(Product 1)# You bought 1 Times 
(Product 1)# You bought 1 Times 
(Product 2)# You bought 1 Times 
(Product 1)# You bought 1 Times 
(Product 2)# You bought 1 Times 
(Product 1)# You bought 1 Times 
(Product 2)# You bought 1 Times 

代碼，但我需要的結果應該看起來像

(Product 2)# You bought 4 Times 
(Product 1)# You bought 4 Times 

Answer 1

來完成，你需要一個新的陣列來存儲實際數量爲每種產品

$quantity_per_product = array(); 

，當你的foreach項更新此數組

if(array_key_exists($_product_id, $quantity_per_product)){ 
    $quantity_per_product[$_product_id] += $item['qty'] 
} 
else{ 
    $quantity_per_product[$_product_id] = $item['qty'] 
} 

因此實際的代碼應該是這個樣子：

$quantity_per_product = array(); 

//Loop trough the order items and see if it is a product we need to cehck 
foreach($items as $item) {   
    if($subtotal== 0 && in_array($item['product_id'], $target_products)) { 
     $_product_id = $item['product_id']; 
     if(isset ($_product_id)){ 
       if(array_key_exists($_product_id, $quantity_per_product)) 
       { 
        $quantity_per_product[$_product_id] += $item['qty'] 
       } 
       else{ 
       $quantity_per_product[$_product_id] = $item['qty'] 
       } 
     } 
    } 
} 
foreach($quantity_per_product as $p_id => $qty){ 
    echo '('. get_the_title($p_id). ')# You bought '.$qty.' Times<br>'; 
} 

希望這有助於！
