无法将变量从控制器传递到模型以处理codeigniter中的多个上载字段

// 加载文件上传库
$this->load->library('upload');

// 配置上传参数
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = 1000;

// 初始化上传类
$this->upload->initialize($config);

// 处理每个上传字段
if ($this->upload->do_upload('field1')) {
    $data1 = $this->upload->data();
} else {
    $error1 = $this->upload->display_errors();
}

if ($this->upload->do_upload('field2')) {
    $data2 = $this->upload->data();
} else {
    $error2 = $this->upload->display_errors();
}

// 将变量传递给模型进行处理
$this->load->model('your_model');
$this->your_model->processUploads($data1, $data2);

class Your_model extends CI_Model {
    public function processUploads($data1, $data2) {
        // 处理上传的文件数据
        // 进行文件处理、存储或其他操作
    }
}
