Method of mutual call between ThinkPHP controllers

In this paper, the method of mutual call between ThinkPHP controllers is described by examples. Share it for your reference. The specific implementation method is as follows:

In the same project as ThinkPHP, how do the methods of the two controllers call each other? ThinkPHP provides an A () that allows methods between controllers to call each other so that code can be reused.

There seems to be no official documentation for the use of the A () method, so let's take an example of using the A () method.

There are two controllers, ColumnsAction and NewsAction. ncatlist () is the categorized list method of ColumnsAction, and now I'm going to call the ncatlist () method in the controller NewsAction.

The code is as follows:

class ColumnsAction extends Action{   

public function ncatlist(){  

    $Columns=new Model;  

                     

    $News = M("News");  

    $list=$Columns->query("SELECT concat(colPath,'-',colId) AS bpath, colId,colPid,colPath, colTitle, description,ord FROM ".C('DB_PREFIX')."columns where typeid=1   

      

ORDER BY bpath, colId");  

                                  

       $this->assign('alist',$list);       

      }  

}  

class NewsAction extends CommonAction {  

      

    //  Home page   

    public function index() {  

   $Columns=A("Columns");  

   $Columns->ncatlist();  

}

In this way, you can loop alist in the template to get the classification list.

Note: The above code is a code version of WBlog 3.0 (using the core package of thinkphp 3.0), but I looked at the core packages of thinkphp 3.1 and thinkph 3.12 that still retain the A method.

I hope this article is helpful to the PHP programming based on ThinkPHP framework.
