codeingiter分页类中的自定义查询

Question

我正在使用codeigniter分页类，并被卡在这段代码中！ 以下代码读取employees表中的整列，但我的查询包含一个连接。我真的不知道如何使用配置设置来运行我自己的查询！

$config['per_page'] = 20; 
$view_data['view_data'] = $this->db->get('employees', $config['per_page'], $this->uri->segment(3)); 

我自己的查询：

$this->db->select('emp.code as emp_code,emp.fname as emp_fname,emp.lname as emp_lname,emp.faname as emp_faname,emp.awcc_phone as emp_phone,emp.awcc_email as emp_email,position as position,dep.title as department'); 
$this->db->from('employees as emp'); 
$this->db->join('departments as dep','dep.code=emp.department_code'); 
$this->db->where('emp.status = 1'); 
$employees_list = $this->db->get(); 
return $employees_list; 

Answer 1

你的做法是完全错误的。 在控制器做这样的

$this->load->model('mymodel'); 
$config['per_page']  = 20; 
$view_data['view_data'] = $this->mymodel->getEmployees($config['per_page'], $this->uri->segment(3)); 

MODLE功能

function getEmployees($limit = 10 , $offset = 0) 
{ 
    $select = array(
        'emp.code as emp_code', 
        'emp.fname as emp_fname', 
        'emp.lname as emp_lname', 
        'emp.faname as emp_faname', 
        'emp.awcc_phone as emp_phone', 
        'emp.awcc_email as emp_email', 
        'position as position', 
        'dep.title as department' 
    ); 

    $this->db->select($select); 
    $this->db->from('employees as emp'); 
    $this->db->join('departments as dep','dep.code=emp.department_code'); 
    $this->db->where('emp.status',1); 
    $this->db->limit($offset , $limit); 
    return $this->db->get()->result(); 
}
