The method of realizing mutual invocation between thinkphp controller _php instance

This paper illustrates the method of mutual invocation between thinkphp controllers. Share to everyone for your reference. The implementation methods are as follows:

thinkphp How do the two-controller methods call each other in the same project? Thinkphp provides a () that allows the methods of the controller to be invoked with each other so that the code can be reused.

The official seems to have no documentation for the A () method, and now, for example, use a () method.

There are two controllers, Columnsaction and newsaction. Ncatlist () is a Columnsaction classification list method, and now I want to call the Ncatlist () method in the controller newsaction.

The code is as follows:

Copy Code code 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
Public Function index () {
$Columns =a ("Columns");
$Columns->ncatlist ();
}

So in the template you can loop alist to get the list of categories.

Description: The above code is WBlog3.0 (using thinkphp3.0 Core package) of the code version of the break, but I looked at the thinkphp3.1 and thinkph3.12 core package also retains a method.

I hope this article will help you with the PHP program design based on thinkphp framework.
