在 Magento 中，我有一個(gè)包含產(chǎn)品的數(shù)組，我想從這些產(chǎn)品中獲得它們所在的類別。這就是我所擁有的，但我正在使用 foreach 來(lái)瀏覽產(chǎn)品，因此需要?jiǎng)h除重復(fù)項(xiàng).我已經(jīng)有了 foreach 的類別名稱，但是現(xiàn)在需要?jiǎng)h除一些重復(fù)項(xiàng)。<?php foreach ($_productCollection as $_product): ?> <div class="bk-all-products"> <?php $bk_product_id = $_product->getCategoryIds(); $bk_category_id = $bk_product_id[1]; $categoryId = $bk_category_id; $_objectManager = \Magento\Framework\App\ObjectManager::getInstance(); $category = $_objectManager->create('Magento\Catalog\Model\Category') ->load($categoryId); $bk_category_id_name = $category->getName(); echo $bk_category_id_name; echo "<br><br>"; ?> </div><?php endforeach; ?>附加信息當(dāng)我還在 foreach 中打印數(shù)組時(shí)，這就是返回值：數(shù)組 ( [0] => 354 [1] => 362 [2] => 360 [3] => 414) Cafe?nevrije koffie數(shù)組 ( [0] => 354 [1] => 362 [2] => 364 [3] => 414) Cafe?nevrije koffie數(shù)組 ( [0] => 354 [1] => 367 ) Koffiepakketten數(shù)組 ( [0] => 354 [1] => 364 )數(shù)組 ( [0] => 354 [1] => 360 ) 濃縮咖啡數(shù)組（[0] => 354 [1] => 360 [2] => 414）Espressokoffie數(shù)組（[0] => 354 [1] => 364 [2] => 414）數(shù)組（[0] => 354 [1] => 360 [2] => 414）Espressokoffie數(shù)組 ( [0] => 354 [1] => 367 ) Koffiepakketten數(shù)組 ( [0] => 354 [1] => 367 ) Koffiepakketten數(shù)組 ( [0] => 367 [1] => 354 )數(shù)組 ( [0] => 367 [1] => 354 )

最簡(jiǎn)單的方法是將已經(jīng)顯示的類別存儲(chǔ)在 an 中，Array并使用in_array檢查您要顯示的類別是否已經(jīng)在其中
編輯：存儲(chǔ) id 可能比存儲(chǔ)名稱更好，因?yàn)槿绻呀?jīng)獲取，您可以避免獲取名稱：
<?php
$diplayed_categories = []; //initializing array
foreach ($_productCollection as $_product):
?>
<div class="bk-all-products">
<?php
$bk_product_id = $_product->getCategoryIds();
$bk_category_id = $bk_product_id[1];
if(!in_array($bk_category_id, $diplayed_categories)){ //testing if not in array
$diplayed_categories[] = $bk_category_id; //filling the array
//moved inside the if, no need to fetch it again if it exists
//$categoryId = $bk_category_id; //useless var
$_objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$category = $_objectManager->create('Magento\Catalog\Model\Category')
->load($bk_category_id); //replaced by $bk_category_id
$bk_category_id_name = $category->getName();
echo $bk_category_id_name;
echo "<br><br>";
}
?>
</div>
<?php endforeach; ?>
