別の配列内で配列をプッシュする方法

Question

サブカテゴリの名前とその特定のサブカテゴリに関連する製品を配列に格納したいと考えています。予想通り

以下

私のコードは、

f ($sub_category->num_rows > 1) { 
    while ($row = mysqli_fetch_array($sub_category)) { 
    $subcategory_id = $row['sub_cat_id']; 
    $subcategory_name['sub_category_name'][] = $row['sub_cat_name'];    
    $sql_subrec = "SELECT es_product_description.name AS prod_name FROM es_product_to_category LEFT JOIN es_product_description ON es_product_description.product_id=es_product_to_category.product_id LEFT JOIN es_product ON es_product_description.product_id = es_product.product_id WHERE es_product_to_category.category_id = $subcategory_id AND es_product.status=1"; 
    //echo "<pre>";print_r($sql_subrec); 
    $sub_product = $conn->query($sql_subrec); 
    while ($prow = mysqli_fetch_assoc($sub_product)) { 
     $subcategory_name['sub_category_name']['products_name'][] = $prow['prod_name']; 
    } 
    } 

    //$subcategory_name[] = array('product_data' => $subcategory_name,); 
    //echo "<pre>";print_r($subcategory_name); 
    echo "<pre>";print_r($subcategory_name);  
} 

結果が来ていません。

関連するサブカテゴリ配列内の製品を取得したいのですが、最初の配列にすべてが入っています。

Answer 1

限り私はあなたからの理解などの限られたあなたは自分の第二whileにこのような何かをする必要があるかもしれません。説明：

$subcategory_name['sub_category_name'][$row['sub_cat_name']]['products_name'][] = $prow['prod_name']; 

これはちょうど推測です...期待される出力と実際の出力を投稿してください。

Answer 2

これを試してください。 「サブカテゴリ名」&「の製品名は」単一の下に来る「サブカテゴリーID」キーインデックス

if ($sub_category->num_rows > 1){ 
     while ($row = mysqli_fetch_array($sub_category)){ 
      $subcategory_id = $row['sub_cat_id']; 
      $subcategory_name[$subcategory_id]['sub_category_name'][] = $row['sub_cat_name']; 
      $sql_subrec = "SELECT es_product_description.name AS prod_name FROM es_product_to_category LEFT JOIN es_product_description ON es_product_description.product_id=es_product_to_category.product_id LEFT JOIN es_product ON es_product_description.product_id = es_product.product_id WHERE es_product_to_category.category_id = $subcategory_id AND es_product.status=1"; 
      //echo "<pre>";print_r($sql_subrec); 
      $sub_product = $conn->query($sql_subrec); 
      while ($prow = mysqli_fetch_assoc($sub_product)){ 
        $subcategory_name[$subcategory_id]['products_name'][] = $prow['prod_name']; 
      } 
     } 
     echo "<pre>";print_r($subcategory_name);   
    }
