我有使用杂货CRUD进行文件上传的以下代码

function test(){
        $crud=new grocery_CRUD();       
        $crud->set_table('test');
        $crud->add_fields('name', 'image');
        $crud->set_field_upload('image', 'test');
        $crud->callback_before_upload('image', array($this, 'before_test_upload'));
        $output=$crud->render();
        $output->page_title="Test Page";
        $this->_crud_output($output);       
    }
function before_test_upload($files_to_upload, $field_info){
        // Here I want to check the file format before that file upload to source folder.
    }
