在Codeigniter中

Question

我有一个问题，使用codeigniter进行多个文件上传 这是我的看法

<input type="file" name="song_name[]" value="" id="song_name">
<input type="file" name="song_name[]" value="" id="song_name">
<input type="file" name="song_name[]" value="" id="song_name">

这个输入元素在form with multipart / formdata

我正在使用具有相同名称的jquery创建每个文本框 这是我上传文件的控制器代码

/* Conf */
$config['upload_path'] = './uploads/test/';
$config['allowed_types'] = 'gif|jpg|png|mov|mp3|aiff|mpeg|zip';
$config['max_size'] = '30000';
$config['max_width'] = '1024';
$config['max_height'] = '1024';
$config['file_ext_tolower'] = 'TRUE';
$config['remove_spaces'] = TRUE;

$this->load->library('upload', $config);
$filesCount = count($_FILES['song_name']['name']);
echo $filesCount;
print_r($_FILES['song_name']); exit;
for($i = 0; $i < $filesCount; $i++) {
    $_FILES['userFile']['name'] = $_FILES['song_name']['name'][$i];
    $_FILES['userFile']['type'] = $_FILES['song_name']['type'][$i];
    $_FILES['userFile']['tmp_name'] = $_FILES['song_name']['tmp_name'][$i];
    $_FILES['userFile']['error'] = $_FILES['song_name']['error'][$i];
    $_FILES['userFile']['size'] = $_FILES['song_name']['size'][$i];

    print_r($_FILES['userFile']);
    $this->upload->initialize($config);
    if($this->upload->do_upload('userFile')) {
        echo "upload";
        $fileData = $this->upload->data();
        $uploadData[$i]['file_name'] = $fileData['file_name'];
        $uploadData[$i]['created'] = date("Y-m-d H:i:s");
        $uploadData[$i]['modified'] = date("Y-m-d H:i:s");
    } else {
        $error = array('error' => $this->upload->display_errors());
        print_r($error);
    }
}

所以请帮我解决这个问题，让我知道如何使用此方法上传
