如何在另一個陣列中推送陣列

Question

我想存儲與該特定子類別相關的子類別名稱和產品。

下面是我的代碼，

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);  
} 

結果不來預期。

我想獲取相關子類別數組內的產品，但它將在第一個數組中包含所有內容。

    [sub_category_name] => Array

Answer 1

至於我是從你有限的解釋明白你可能只是需要做這樣的事情在你的第二個while：

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

但這只是一個猜測......請發佈預期的輸出和實際的輸出。

Answer 2

試試這個。 「子類別名稱」 &「產品名稱」來下單「子類別ID」 keyindex

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);   
    }
