像$ smarty.session一样创建自己的Smarty变量

Question

So I am using a custom PHP Session handler (One that kinda works like the one in Laravel if you're familiar with the framework), which don't register to the $_SESSION superglobal, so I can't use {$smarty.session.some_data} to access it.

However, in my Smarty template I still would like to retrieve values stored in the session without needing to assign the value manually to a Smarty variable all the time. What would be the best way to create a way to access my session data?

Thanks in advance!

Probably there's no way to use syntax $smarty.yourarray.data but this syntax is used for global array ($_POST, $_GET, $_SESSION, $_COOKIE, $_SERVER).

However you can access static class in the same method as in PHP.

Assume you have the following class in PHP file:

class Session
{
    public static function get($data) {
        if (is_int($data)) {
            return $data * 3;
        }
        return $data;
    }
}

Now, you don't need to assign anything to Smarty.

When in Smarty file you want to access this class method you simply need to use:

{Session::get('something')}<br />
{Session::get(2)}

And you will get result:

something
6

as expected.

So you don't have to do anything to access this class (no modifiers/functions, you even don't need to assign this class).

However let's assume you have your Session class in namespace:

<?php

//session.php

namespace MySession;

class Session
{
    public static function get($data) {
        if (is_int($data)) {
            return $data * 3;
        }
        return $data;
    }
}

If you want to this static class inside Smarty you will need to register your class:

require ('session.php');
$smarty->registerClass('Session', 'MySession\Session');

to make it work (you cannot use namespace in TPL file as far as I know).
