限制包含特定类别的产品的购物车数量

Question

如果属于特定类别 ID 的产品数量大于 3，我想显示一条消息。

这是我目前的情况，如果产品包含类别 ID，可以设置和 "if" 声明？

    <?php
     $session= Mage::getSingleton('checkout/session');
     $items = $session->getQuote()->getAllItems();
     $class2 = "hide";
     $count = 0;


   foreach ($items as $item) {

     $categories = $item->getProduct()->getCategoryIds();

     foreach ($categories as $categoryId){

       if($categoryId == 125) $count++;   
     }

     if($count > 3) $class2 = "show";
      }
    ?>

    <div class="<?php echo $class2; ?> warning">
        <p style="margin:0;" class="red">Flash Sale Quantity Is Limited To 3</p>
    </div>

可能类似这样的方法可以解决问题...第一步是找到类别 ID，然后在 if 语句中开始计数，如果 $count 是 >3，则 $class2 将是 "show";

<?php
 $session= Mage::getSingleton('checkout/session');
 $items = $session->getQuote()->getAllItems();
 $class2 = "hide";
 $count = 0;

 foreach ($items as $item) {

    $categories = $item->getProduct()->getCategoryIds();

    foreach ($categories as $categoryId){

        if($categoryId == 125) { 

            if($count > 3) { $class2 = "show" }

            $count = $count + 1;
        }
    }   
 }

?>

<div class="<?php echo $class2; ?> warning">
    <p style="margin:0;" class="red">Flash Sale Quantity Is Limited To 3</p>
</div>
