thinkphp how to pass values between different functions of different action classes

thinkphp how to pass values between different functions in different action classes
I use thinkphp to do the login page.
The landing page submits the form to action= "__app__/index/login_do", then I wrote the Login_do function in the Indexaction class:
Public Function Login_do ()
{
if ($_session[' verify '! = MD5 ($_post[' Userauthcode ']))
{
$this->error (' Verification code Error! ');
}
$username =$_post[' username '];
$password =$_post[' password '];
$password =md5 ($password);

$user =m (' user ');
$res = $user->where ("User_name= ' $username ' && password= ' $password '")->find ();
if ($res)
{
Redirect ('.. /home/home ', 1, "Login successful!" page is jumping ... ");
}
Else
{
$this->error (' Login failed! ');
}
}




Here is the Homeaction class:
Class Homeaction extends Action
{
Public Function Home ()
{
$this->display ();
}
}




.../tpl/home/home.html is the homepage.





Now the question is: I want to display the user name on the homepage, how can I send the value of the user name to the home.html display, the high-finger teaching, to point tips, thank you!

------Solution--------------------
Do log in when the Session is saved and then the home controller with $name=session:: Get (' name ') to obtain the user name

Then $this->assign (' name ', $name);
Output template last on template page {$name}

According to the description of the #1, implemented in the __url__/top correspondence method
