Fatal error: Call to undefined method News_model::set_news() in /mnt/hgfs/workspace/test/application/controllers/news.php on line 54
谷歌翻译我还是懂的  但是请看下面代码  请问哪里出了错  为什么没被定义呢
致命错误：调用未定义的方法News_model:: set_news（）在第54行到/ mnt /生长因子，/工作区/测试/应用程序/控制器/ news.php上

人家都说了你的news_model里没有定义set_news方法。。。。。。而你的set_news我看了定义在当前类里，那就用$this->set_news()吧。。。/

bax

你使用 $this->news_model->set_news() ，但是你沒加載 $this->load->model('news_model')

而且你的 news_model 在同個class，可以直接用 $this->set_news()
