CodeIgniter 1.7.2无效的上传目录

Question

我正在尝试使用CodeIgniter 1.7.2创建一个图像上传表单

但是,当我尝试上传图像时,CI通知我上传目录无效.

为了检查这一点,我将一个文件上传到uploads目录中test.txt,Hello, World!然后用内容调用它,然后回显它的内容,然后,它说,你好.除此之外,我可以浏览目录并在我的浏览器中查看它的内容,因此目录肯定存在且可见.

控制器:

class Pictures extends Site_Controller {
    // snip...
    public function upload() {
        $this->load->helper('form');
        $this->_render('Do Upload','pictures/upload',array('msg'=>''));
    }
    public function do_upload() {
        $this->load->helper('form');

        $config['upload_path'] = base_url().'uploads/';
        // test the directory:
        // echo file_get_contents($config['upload_path'].'test.txt');
        // should echo "Hello, World!"
        $config['allowed_types'] = 'gif|jpg|png';
        $config['max_size']    = '2048';
        $config['max_width']  = '1024';
        $config['max_height']  = '768';

        $this->load->library('upload', $config);

        if ( ! $this->upload->do_upload())
        {
            $data = array('msg' => $this->upload->display_errors());

            $this->_render('Do Upload (Errors!)','pictures/upload',$data);
        }    
        else
        {
            $uploaddata = $this->upload->data();
            $this->load->model('pictures_Model','pictures');
            $this->pictures->insertUploaded($uploaddata,$this->input->post('name'),$this->input->post('caption'));

            $data['msg'] = 'Successful Upload!';
            $this->_render('Do Upload (Success!)','pictures/upload',$data);
        }
    }
    //...
}

$this->_render() 只是一个快捷方式函数,它使用指定标题在具有指定标题的布局中包装指定视图.

pictures/upload 视图:

<h1>Do Upload</h1>
<? if (isset($msg)) echo $msg; ?>

<?= form_open_multipart('pictures/do_upload');?>

<input type="file" name="userfile" />
<input type="text" name="name" />
<input type="text" name="caption" />

<br /><br />

<input type="submit" value="Upload" />

</form>

最后,也许是不必要的,模型插入:

public function insertUploaded($data,$name,$caption) {
    $row = array();
    $row['filename'] = $data['file_name'];
    $row['mime'] = $data['file_type'];
    $row['size'] = $data['file_size'];
    $row['name'] = $name;
    $row['caption'] = $caption;
    $row['img'] = file_get_contents($data['full_path']);

    $this->db->insert('pictures',$row);
}

知道为什么我的上传目录无效吗？

Answer 1

 $config['upload_path'] = base_url().'uploads/';

你应该改为:

 $config['upload_path'] = './uploads/';
