Question

观点：

<table class="table table-hover">
                  <tr>

                    <th>Heading</th>
                    <th>Description</th>
                  </tr>
                  <?php foreach ($result as $row) { ?>
                  <tr>


                    <td><?php echo $row->heading_name ;?></td>
                    <td><?php echo $row->description_name; ?></td>

                  </tr>
                  <?php } ?>
 </table>

型号：

function view_description(){
        $this->db->order_by("id","DESC");
        $query = $this->db->get("description_update");
        return $query->result();
   }

控制器：

public function update_heading(){
        $config = array(
            array(
                'field' =>'heading_name', 
                'label' =>'Name',
                'rules' => 'trim|required'
            ),
            array(
                'field' => 'description_name',
                'label' => 'Description',
                'rules' => 'trim|required'
            )
        );

        $this->form_validation->set_rules($config);
        if ($this->form_validation->run()== FALSE)
        {
            $this->load->view('modules/admin/general.php');
        }
        else{
            $data = array(
            'heading_name'  => $this->input->post('heading_name'),
            'description_name' => $this->input->post('description_name')
            );

            $this->description_model->add_description($data);

            $data['message'] = 'Data inserted Successfully';
            $this->load->view('modules/admin/general.php',$data);
        }
        $data['result']= $this->description_model->view_description();
        $this->load->view('modules/admin/general.php',$data);
        // print_r($data);


    }

我想在我的视图文件中查看结果数据，但是当$ result数据显示另一个视图文件中的结果时，它表示找不到结果变量但是在相同的代码中。我不知道该怎么办。注意：我是CodeIgniter的新手

TIA

Answer 1

无需在29行中加载此视图，因为您的目标是加载结果数据。

$这 - ＆GT;负载＆gt;查看（ '模块/管理/ general.php'，$数据）;

Answer 2

尝试将$data['result']置于代码顶部，并在表单的错误部分添加$data以及

加载视图时，您也不需要.php

$this->load->view('modules/admin/general', $data);

功能

public function update_heading(){

    $config = array(
        array(
            'field' =>'heading_name', 
            'label' =>'Name',
            'rules' => 'trim|required'
        ),
        array(
            'field' => 'description_name',
            'label' => 'Description',
            'rules' => 'trim|required'
            )
    );


    $this->form_validation->set_rules($config);

    $data['message'] = '';

    // $data['result'] = array();

    $data['result'] = $this->description_model->view_description();

    if ($this->form_validation->run()== FALSE) {

        $this->load->view('modules/admin/general', $data);

    } else {

        $data = array(
            'heading_name'  => $this->input->post('heading_name'),
            'description_name' => $this->input->post('description_name')
        );

        $this->description_model->add_description($data);

        $data['message'] = 'Data inserted Successfully';

        $this->load->view('modules/admin/general',$data);
    }
}

在视图文件codeigniter中找不到变量
