Smarty:是否可以在模板内调用PHP函数(从controller类)? [英] Smarty: is it possible to call a PHP function (from the controller class) inside the template?

问题描述

我在控制器类中创建了一个需要在模板内部使用的函数(因为该模板已多次渲染(每个模板是网站上的一则帖子，并且它们都将在Newsfeed中显示为不同的值)有没有办法在一个聪明的变量上调用它?假设您在控制器中创建了一个函数:

I created a function in the controller class that needs to be used inside the template (because the template it rendered many times (each template is a post on the website, and they will be all displayed with different values in the newsfeed). Is there a way to call it on a smarty variable? Say you created a function in the controller:

public function foo($bar){
       $bar++;
       return $bar;
}

然后在模板中:

{$ smarbar | foo} 或类似的

推荐答案

您可以注册一个修饰符，该修饰符将调用类的给定方法:

You could register a modifier that will call a given method of a class:

class SomeClass {
    public function someMethod($value)
    {
        // return modified value
    }
}

$smarty = new Smarty();

$smarty->registerPlugin('modifier', 'myModifier', array('SomeClass', 'someMethod'));
// or
$instance = new SomeClass();
$smarty->registerPlugin('modifier', 'myModifier', array($instance, 'someMethod'));

现在您可以在模板中使用它:

and now you can use this inside your template:

{$someVar|myModifier}

这是 registerPlugin 文档.
