Question

这是我的控制器代码。

function edit_hotel($id) {
            $hotel = $this->hotel_model->get_hotel($id);

            $data['title'] = 'Edit Hotel';

            $this->form_validation->set_rules('hotelname', 'Hotel Name', 'required|xss_clean');
            $this->form_validation->set_rules('hotellocation', 'Hotel Location', 'required|xss_clean');
            $this->form_validation->set_rules('hotelphone', 'Hotel Phone', 'required|xss_clean');
            $this->form_validation->set_rules('hotelimg', 'Hotel Image', 'required|xss_clean');
            $this->form_validation->set_rules('hotelabout', 'Hotel About', 'required|xss_clean');
        if ($this->form_validation->run() === true)
                {

                $config['upload_path'] = './images/hotelimages';
     $config['allowed_types'] = 'gif|jpg|png';
     $config['max_size']    = '1000000';
     $config['overwrite'] = TRUE;
     $config['remove_spaces'] = TRUE;
     $config['encrypt_name'] = FALSE;
    print_r($config);
    echo "<br>after config<br>";
     $this->load->library('upload', $config);
     $field_name = "hotelimg";
     if ( ! $this->upload->do_upload($field_name))
            {
     $error = array('error' => $this->upload->display_errors());

                $this->load->view('admin/edit_hotel', $error);
                }
                else {
                $image_data = $this->upload->data();
                print_r($image_data);
                echo "<br>after image_data<br>";
                $data = array(
                    'hotelname'             => $this->input->post('hotelname'),
                    'hotellocation'     => $this->input->post('hotellocation'),
                    'hotelphone'            => $this->input->post('hotelphone'),
                    'hotelimg'      =>    $image_data['full_path'],
                    'hotelabout'            => $this->input->post('hotelabout')
                );





                    $this->hotel_model->update_hotel($id, $data);

                    $this->session->set_flashdata('message', "<p>Hotel updated successfully.</p>");

                    redirect(base_url().'index.php/admin/hotel_controller/index');
                }

            }


            $data['hotel'] = $hotel;



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

这是模型

从数据库中获取数据以编辑表单字段

function get_hotel($id) {
        $this->db->select('id, hotelname, hotellocation, hotelphone,hotelimg,    
hotelabout');
        $this->db->where('id', $id);
        $this->db->limit(5);
        $query = $this->db->get('hotel_content');

        return $query->row_array();
    }

更新数据库

public function update_hotel($id, $data)
    {
        $this->db->where('id', $id);
        $this->db->update('hotel_content', $data);
    }

这是查看页面

<?php $id = $hotel['id']; ?>
<?php echo form_open("admin/hotel_controller/edit_hotel/$id");?>
    <table width="700" border="1" cellpadding="0" cellspacing="2" align="center">
        <tr>
            <td width="234" align="right"> <div align="left">Hotel Name:: </div></td>
          <td width="454"><input type="text" name="hotelname" id="hotelname" value="<?php  
            echo $hotel['hotelname']; ?>" class="input_field"/></td>
        </tr>
        <tr>
            <td width="234" align="right"> <div align="left">Hotel Location: </div></td>
            <td><input type="text"  name="hotellocation" id="hotellocation" value="<?php  
            echo $hotel['hotellocation']; ?>" class="input_field"/><?php //echo form_input($hotellocation); ?></td>
        </tr>
        <tr>
            <td align="right"><div align="left">Hotel Phone:</div></td>
            <td><input  type="text" name="hotelphone" id="hotelphone" value="<?php 
            echo $hotel['hotelphone']; ?>" class="input_field"/><?php //echo form_input($hotelphone); ?></td>
        </tr>
        <tr>
            <td bgcolor="#FFFFFF" align="center"><div align="left">Hotel Image:</div></td>
            <td><input type="file" name="hotelimg" id="hotelimg" size="33" value="<?php 
            echo $hotel['hotelimg']; ?>" /><?php //echo form_input($hotelimg); ?>
            <input type="hidden" name="hotelimg" id="hotelimg" value="<?php 
            echo $hotel['hotelimg']; ?>" /></td>
        </tr>
        <tr>
            <td align="right"><div align="left">Hotel About:</div></td>
            <td><textarea name="hotelabout" id="hotelabout" cols="34" rows="5"> <?php 
            echo $hotel['hotelabout']; ?></textarea><?php //echo form_textarea($hotelabout); ?></td>
        </tr>

        <tr>
            <td>&nbsp;</td>
            <td><?php echo form_submit('submit', 'Submit');?>
                <input type="button" name="btnBack" id="btnBack" value="Back" onclick="window.location.href='<?php echo base_url() ?>admin/hotel_controller/index'" />          </td>
        </tr>
    </table>
<?php echo form_close(); ?>

上面的代码不会执行任何更新数据库中图像路径的操作。所以任何人都可以帮助我纠正它。提前感谢你

所以显示的图像路径是这样的

print_r($image_data)：

Array (
[file_name] =>
[file_type] =>
[file_path] => ./images/hotelimages/(**name of the image should be here**)
[full_path] => ./images/hotelimages/(**name of the image should be here**)
[raw_name] =>
[orig_name] =>
[client_name] =>
[file_ext] =>
[file_size] =>
[is_image] =>
[image_width] =>
[image_height] =>
[image_type] =>
[image_size_str] =>
)

在image_data之后

print_r($data)：

Array (
[hotelname] => aditya Hotels
[hotellocation] => Hyderbad
[hotelphone] => 04056894236
[hotelimg] => ./images/hotelimages/(**name of the image should be here**)
[hotelabout] => Aditya Sarovar Premiere is a well known lodging destination among many international and local tourists. Aditya Sarovar Premiere offers some state of the art rooms and modern facilities at affordable prices. It also has a fully equipped gym and a swimming pool. Perfect abode for all business and leisure guests, Aditya Sarovar Premiere is a great place to stay when in Hyderabad.

Answer 1

在视图中使用 form_open_multipart（）代替 form_open（），以允许文件上传。

使用Codeigniter更新数据库中的图像路径？
