例如，如果我上传文件foo.png，我如何在上传控制器中获得字符串"foo.png"？
控制器代码为：
<?php
class Upload extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'url'));
$this->load->database();
}
function do_upload($folder)
{
$config['upload_path'] = './userdata/'. $folder . '/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload())
{
$error = array('error' => $this->upload->display_errors());
echo $this->upload->display_errors();
}
else
{
$data = array('upload_data' => $this->upload->data());
echo "<p>File sucesfully uploaded</p>";
$filename = // How do I get the filename here
}
}
}
?>
如何将$filename设置为上传文件的文件名？
来自官方CI手册：
$this->upload->data()
This is a helper function that returns an array containing all of the data related to the file you uploaded. Here is the array prototype:
Array
(
[file_name] => mypic.jpg
[file_type] => image/jpeg
[file_path] => /path/to/your/upload/
[full_path] => /path/to/your/upload/jpg.jpg
[raw_name] => mypic
[orig_name] => mypic.jpg
[client_name] => mypic.jpg
[file_ext] => .jpg
[file_size] => 22.2
[is_image] => 1
[image_width] => 800
[image_height] => 600
[image_type] => jpeg
[image_size_str] => width="800" height="200"
)
因此，在您的情况下，保存$this->upload->data()函数结果的$data变量应该包含您所需的有关已上载文件的所有信息。
特别是$data['upload_data']['file_name']正是您想要的。
试试这个！
$data = $this->upload->data();
echo $data['file_name'];
echo $data['raw_name'].$data['file_ext'];
应该完成
例如，你上传了你的图像
if($this->upload->do_upload('upload_data')) {
$data = $this->upload->data();
echo $data['raw_name'].$data['file_ext'];
}
