【问题描述】:
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 会通知我上传目录无效。
为了检查这一点,我上传了一个名为 test.txt 的文件到 uploads 目录,内容为 Hello, World!,然后我回显了它的内容,你瞧,它说你好。除此之外,我可以浏览到该目录并在我的浏览器中查看它的内容,因此该目录肯定存在并且可以查看。
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);
}
}
//...
}
$this->_render()只是一个快捷函数,将指定视图与指定数据包装在具有指定标题的布局中。
pictures/upload查看:
<h1>Do Upload</h1>
<? if (isset($msg)) echo $msg; ?>
<?= form_open_multipart('pictures/do_upload');?>
<input type="file" name="userfile" />
<input type="text" name="name" />
<input type="text" name="caption" />
<br /><br />
<input type="submit" value="Upload" />
</form>
最后,可能没有必要,插入模型:
public function insertUploaded($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?
