我想按产品价格按升序对此数组进行排序。我怎么能这样做?
Array
(
[0] => stdClass Object
(
[product_id] => 16
[product_name] => Ferrari 4802
[product_details] => I know this car is good. Because I have driven this car 10 year.
[product_quantity] => 1

因为数组是由数据库查询生成的,所以您可以轻松地让查询为您进行排序。
您不显示模型代码,但假设您使用的是查询生成器(a.k.a.Active Record),则在执行$this->db->get()
之前,您需要在模型中使用以下内容。
$this->db->order_by('product_price', 'ASC');
以下是一些显示完整查询的示例代码。它假设该表名为“products”,您希望选择所有表的字段,并且只需要特定的“category_id”。
在模型文件中:
public function product_by_category($category)
{
$query = $this->db
->where('category_id', $category)
->order_by('product_price', 'ASC')
->get('products');
//return all records or NULL if no records are found
return $query->num_rows() > 0 ? $query->result() : NULL;
}
