路由是这样的

数据模型是这样的

我http://localhost/ci//index.php/content/del/1
后就是404 page not found
不知道是不能传参还是路由问题
回复讨论(解决方案) 如果象 http://localhost/ci/index.php/content/del/1 这样的 url 会找不到文件的话
就表示你的 web 服务器不支持 path_info
如果web 服务器不支持 path_info，
为什么
http://localhost/ci//index.php/content/1
确能显示文章
$route['content/(:any)'] = 'content/view/$1';
写路由的一个原则：会被包含的规则要写在包含他的规则上面，否则就应用不到了。
5楼正解，
$route['content/del/(:any)'] = 'content/del/$1';一定要放在
$route['content/(:any)'] = 'content/view/$1';的前面，否则会背后截获
