thinkphp Frame 404 Page setup Only three steps _php tips

404 page is the system can not find the requested operation method and can not find the requested controller name of an error behavior optimization.

In many sites will have to use 404 pages, in the thinkphp frame how to set it, next I introduce one of the methods, specific content as follows

Step One: build a EmptyController.class.php in the Home/comtroller in the thinkphp framework with the following code:

<?php
namespace HomeController;
Use Thinkcontroller;
Class Emptycontroller extends controller{
  
//null Operation _empty () method
  function _empty () {
    header ("http/1.0 404 Not Found ");
    $this-> Display ("public:404");
  
  function index () {
    header ("http/1.0 404 Not Found");
    $this-> dislay ("public:404");
  }
? >

Note: where header ("http/1.0 404 Not Found") is defined this status code is not 404.

Step Two: build a common class PublicController.class.php in the Home/comtroller in the thinkphp framework, with the following code:

<?php
namespace HomeController;
Use Thinkcontroller;
Class Publiccontroller extends controller{
  function _empty () {
    header ("location:/bbs/thinkphp/404.html");
  }
}
? > 

Note: the/bbs/thinkphp/404.html in header ("location:/bbs/thinkphp/404.html") is the address of the page jump after you appear 404, You need to correspond to your 404.html page placement bit.

Step three: let all other controllers inherit the PublicController.class.php in step two, such as:

<?php
namespace HomeController;
Use Thinkcontroller;
Class Indexcontroller extends Publiccontroller {public
  function index () {* * *
     }
}
? >

Note: will use Thinkcontroller; Comment out

The above is thinkphp 404 Page setup All content, hope to everybody learns PHP program design to have help.
