Question

我有从ci_products表中获取产品的功能代码如下

function get_product_selections($product_ids = array())
{
    $this->db->select('*');
    $this->db->from('ci_products');
    $this->db->where_in('product_id', $product_ids);

    $products = $this->db->get();
    return $products;
}

现在我想从user_id current user_id的哪个位置抓取我尝试了一些但没有工作的东西我尝试了什么？

function get_product_selections($product_ids = array())
{
    $this->db->select('*');
    $this->db->from('ci_products');
    $this->db->where_in('product_id', $product_ids);
      $this->db->where('user_id',$this->session->userdata('user_id'));
    $products = $this->db->get();
    return $products;
}

Answer 1

$data = $this->db->get_where('product_ids',$product_ids);
$this->db->where_in('product_ids',$data);
$this->db->where('user_id',$this->session->userdata('user_id'));
$query =  $this->db->get();
return $query->result_array();

试试这个：

在您的第一个代码中：

function get_product_selections($product_ids)
{
    $this->db->select('*');
    $this->db->from('ci_products');
    $this->db->where('product_id', $product_ids);

    $products = $this->db->get();
    return $products->result_array();
}

在参数中放入array（）是什么意思？你想要检索产品的数组（）吗？

function get_product_selections()
{
    $this->db->select('*');
    $this->db->from('ci_products');
    $this->db->where('user_id',$this->session->userdata('user_id')); // the user who is currently login
    $products = $this->db->get();

    return $products->result_array(); // return the results
}

获取当前user_id的产品
