无法传递 SQL 数据以在 codeigniter 中查看

Trouble passing SQL data to view in codeigniter

我有一个表格,可以让人们输入数据,然后上传预设图片。我想将该图片标记为 form_id。我能够 运行 LAST_INSERT_ID() 查询并在我将表单插入我的视图后显示它,但我似乎无法在其他任何地方回显该信息。在我的 $update 查询之后,我需要查询到 select_last_id 到 运行,否则 ID 号将被关闭。任何人都可以帮助我将行的价值传递给我的观点吗?这是我的控制器的代码。

function inspection() {

    if($this->input->post('submit')) {
        $array = array(

            'trlr_num' => $this->input->post('trlr_num'),
            'seal' => $this->input->post('seal'),
            'damaged' => $this->input->post('damaged'),
            'truck_num' => $this->input->post('truck_num'),
            'driver_name' => $this->input->post('driver_name'),
            'car_code' => $this->input->post('car_code'),
            'origin' => $this->input->post('origin'),
            'lic_plate' => $this->input->post('lic_plate'),
            'del_note' => $this->input->post('del_note'),
            'live_drop' => $this->input->post('live_drop'),
            'temp' => $this->input->post('temp'),
            'level' => $this->input->post('level'),
            'ship_num' => $this->input->post('ship_num'),
            'trlr_stat' => $this->input->post('trlr_stat'),
            'comment' => $this->input->post('comment')

                        );
        $update = $this->trailer_model->insert_form($array);

        $query = $this->trailer_model->select_last_id();
        $result =& $query->result_array();

        $this->table->set_heading('ID');
        $data['table'] = $this->table->generate_table($result);
        unset($query,$result);


       }
    $level = $this->trailer_model->select_fuel_level();
    $result = $level->result_array();

    $data['options'] = array();
    foreach($result as $key => $row) {
        $data['options'][$row['level']] = $row['level'];
    }
    unset($query,$result,$key,$row);

    $data['label_display'] = 'Fuel Level';
    $data['field_name'] = 'level';

    $status = $this->trailer_model->select_trailer_type();
    $result = $status->result_array();

    $data['options1'] = array();
    foreach($result as $key => $row) {
        $data['options1'][$row['trlr_stat']] = $row['trlr_stat'];
    }
    unset($query,$result,$key,$row);


    $data['label_display1'] = 'Trailer Status';
    $data['field_name1'] = 'trlr_stat';


    $data['page_title'] = 'Trailer Inspection';
    $data['main_content'] = 'dlx/inspection/trailer_inspection_view';


    return $this->load->view('includes/template',$data);

}

}

任何您想在视图上显示的内容,都必须传递给它。

当您设置 $data 时,您错过了添加 $query

控制器:

我知道 $query = $this->trailer_model->select_last_id(); return 只是一个 ID,所以:

$data['last_id'] = $query;

但是如果 $query = $this->trailer_model->select_last_id(); return 只是一个 ID,而是一个数组或其他东西,你应该包括到 return模型方法中的 ID。实际上,了解 $this->trailer_model->select_last_id(); 是什么 returning 是至关重要的。

查看:

echo $last_id; -> 必须回显最后一个 ID,如果 select_last_id() 方法来自您的模型 return 它必须 return.
