Question

我可能甚至没有考虑这个正确的方法或者正确的方式，因为我对CodeIgniter很新，而且我的PHP技能还不是很好。基本上，我所拥有的是一个接受来自$content数组的值的页面（视图）。那部分工作正常。我也有一些数据，我从数据库中提取，也需要在页面上显示。我无法想出一种方法来获取$content和我的值从数据库到我的页面的值。

所以，长话短说：如何从数据库中获取内容，在控制器中设置内容值，并将两者都传递给我的视图？

这是我的型号代码：

class Employees_model extends CI_Model {    

    function get_employees(){
      $query = $this->db->get('employees');
      return $query->result();
    }

}

这是我的控制器功能：

function create(){

    $this->load->helper(array('form', 'url'));
    $this->load->library('form_validation');

    //getting employees content from the db
    $this->load->model('Employees_model');
    if($query = $this->Employees_model->get_employees()){
        $content['employees'] = $query;
    } 

    print_r($content); //this is displaying the correct content from the DB, but having trouble passing it to the view      

    $this->form_validation->set_rules('kpa1', 'KPA 1', 'trim|required');
    $this->form_validation->set_rules('kpa1_rating', 'KPA 1 Rating', 'trim|required|greater_than[0]');

    if ($this->form_validation->run() == FALSE){
        $this->load->view('create_review', $content);

    } else {

        $data = array(
            'kpa1' => $this->input->post('kpa1'),
            'kpa1_rating' => $this->input->post('kpa1_rating')
        );

        $content = array(
            'alert_type' => 'alert-success',
            'message' => 'The review has been saved!'
        );
        $this->load->model('Review_model');
        $this->Review_model->add_review($data);
        $this->load->view('create_review', $content);
       //this is only loading data from the $content array above
    }


}

我可以做到这一点：

function create(){

            $this->load->helper(array('form', 'url'));
            $this->load->library('form_validation');

            $content = array();

            //getting employees content from the db
            $this->load->model('Employees_model');
            if($query = $this->Employees_model->get_employees()){
                $content['employees'] = $query;
            } 

            print_r($content); //this is displaying the correct content from the DB, but having trouble passing it to the view      

            $this->form_validation->set_rules('kpa1', 'KPA 1', 'trim|required');
            $this->form_validation->set_rules('kpa1_rating', 'KPA 1 Rating', 'trim|required|greater_than[0]');

            if ($this->form_validation->run() == FALSE){
                $this->load->view('create_review', $content);

            } else {

                $data = array(
                    'kpa1' => $this->input->post('kpa1'),
                    'kpa1_rating' => $this->input->post('kpa1_rating')
                );
                //pass data to model
                $this->load->model('Review_model');
                $this->Review_model->add_review($data);

                //add more data
                $data['kpa1'] = $this->input->post('kpa1');
                $data['kpa1_rating'] = $this->input->post('kpa1_rating');
                //see if we have employees data and if so add
                if(isset($content['employees'])){
                    $data['employees'] = $content['employees'];
                }

                //pass data to view
                $this->load->view('create_review', $data);
                //this is only loading data from the $content array above
            }


    }
