Codeigniter 3.0：上传后文件名没有改变

Question

我正在通过表单上传图像和文件。但上传后名称并没有改变。在第一次函数调用时，如果名称是 profilePic，那么即使我在 $config['file_name'] 参数中更改名称，这个文件名在每次调用时都保持不变。

函数调用：

    function getAndSaveEmployeeDetails() {
    $resume = 'resume';
    $resume = $this -> do_upload($resume, $employeeID);

    $profilePic = 'profilePic';
    $profilePic = $this -> do_upload($profilePic, $employeeID);

    $cnic = 'cnicScannedImage';
    $cnicScannedImage = $this -> do_upload($cnic, $employeeID); }

//上传函数

public function do_upload($uploadedField, $employeeID) {
//$uploadedField = $this -> input -> post('_hidden_field');
    if (empty($_FILES[$uploadedField]['name'])) {

        $error = "File is empty please choose a file";
        return $error;

    } else {
        $name = '_' . $uploadedField;
        $config['file_name'] = $employeeID . $name;
        $config['upload_path'] = './uploads/' . $employeeID;
        $config['allowed_types'] = 'gif|jpg|jpeg|png|iso|dmg|zip|rar|doc|docx|xls|xlsx|ppt|pptx|csv|ods|odt|odp|pdf|rtf|sxc|sxi|txt|exe|avi|mpeg|mp3|mp4|3gp';
        $config['max_size'] = 2048;
        $config['max_width'] = 0;
        $config['max_height'] = 0;
        $this -> load -> library('upload', $config);

        if (!is_dir('uploads')) {
            mkdir('./uploads', 0777, true);
        }
        $dir_exist = true;
        // flag for checking the directory exist or not
        if (!is_dir('uploads/' . $employeeID)) {
            mkdir('./uploads/' . $employeeID, 0777, true);
            $dir_exist = false;
            // dir not exist
        } else {

        }

        if (!$this -> upload -> do_upload($uploadedField)) {

            if (!$dir_exist)
                rmdir('./uploads/' . $employeeID);

            $error = array('error' => $this -> upload -> display_errors());
            return $error;

            //$this -> load -> view('upload_form', $error);
        } else {
            $data = array('upload_data' => $this -> upload -> data());

            return $path = $data['upload_data']['full_path'];

        }
    }
}

These are the file names and it is caching the first name passed in function call

在getAndSaveEmployeeDetails()的第一行加载upload库，使用

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

不通过任何配置。

然后在do_upload($uploadedField, $employeeID)函数定义你的配置数组后，不要使用$this->load->library('upload', $config); 但使用$this->upload->initialize($config);
