Question

我有一个控制器，我根据客户端ID和项目ID选择值。我的控制器是：

$this->data['editval'] = $this->Add_project_m->displayedit($projectid, $clientid)

在模型中代码是

function displayedit($projectid,$clientid){

      $this->db->select('client_id,project_name,project_location,square_feet,project_value,delete_display,phone,id,name');
      $this->db->where('id', $projectid);
      $this->db->where('client_id', $clientid);
      $query=$this->db->get('new_project');
      return $query->result();
    }

我得到一个空数组。欢迎任何帮助。

Answer 1

请使用$ query-＆gt; row（）而不是$ query-＆gt; result（）

Answer 2

试试这个

function displayedit($projectid,$clientid){

  $this->db->select('client_id,project_name,project_location,square_feet,project_value,delete_display,phone,id,name');
  $this->db->from('new_project');
  $this->db->where('id', $projectid);
  $this->db->where('client_id', $clientid);
  return $this->db->get()->result_array();

}

Answer 3

希望以下代码能够正常运行： function displayedit（$ projectid，$ clientid）{

 $this->db->select('client_id,project_name,project_location,square_feet,project_value,delete_display,phone,id,name');
  $this->db->from('new_project');
  $this->db->where('id', $projectid);
  $this->db->where('client_id', $clientid);
  $qry=$this->db->get();
return ($qry->num_rows(0)>0)? $qry->result() :false;

}
