Answer 1

Alway型号名称以大写字母开头。首先解决了这个问题。然后chek数据库设置

Answer 2

您必须先加载数据库库。在

autoload.php：

$autoload[‘libraries’] = array(‘database’);

Answer 3

public function _construct()
{
    parent::_construct();
    $this->load->model('employee_model');
    $this->load->helper(array('form','url'));
    private $employee_model = 'employee_model';
    }

首先在构造中设置它 然后，像这样称呼它

$this->{employee_model}->saveemployee($save);
