Question

我是CodeIgniter的初学者。我正在尝试获取我上传的一个文件的属性，如名称，类型等。但我无法检索该信息。它正在输出一个空数组。我做错了什么？我试过了：

function do_upload() {

    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'gif|jpg|png|pdf';
    $config['max_size'] = '999999';
    $config['max_width']  = '3000';
    $config['max_height']  = '2000';
    $this->load->library('upload', $config); 

    $details = $this->upload->data();
    echo "<pre>";
    print_r ($details);
    echo "</pre>";        

    if (!$this->upload->do_upload()){
        $error = array('error' => $this->upload->display_errors());
        $this->load->view('upload_form', $error);
    } else {
        $data = array('upload_data' => $this->upload->data());
        $this->load->view('upload_success', $data);
      }
}

输出：

Array
(
    [file_name] => 
    [file_type] => 
    [file_path] => ./uploads/
    [full_path] => ./uploads/
    [raw_name] => 
    [orig_name] => 
    [client_name] => 
    [file_ext] => 
    [file_size] => 
    [is_image] => 
    [image_width] => 
    [image_height] => 
    [image_type] => 
    [image_size_str] => 
)

Answer 1

$this->upload->data()将在执行$this->upload->do_upload()后返回上传的数据。所以试试你的else部分。

$ this-＆gt; upload-＆gt; data（）无效
