twig：创建调用函数的自定义标记

Question

SETUP:

• Twig 1.13.1
• PHP 5.4.3

---

PROBLEM:

I am needing help setting up a custom tag that calls a function that i have already built...

---

Current Code:

Template Code

{% set stories = get_latest_stories(2, sports) %}

{% for story in stories %}
    {{ story.headline }} <br>
{% endfor %}

Controller

$function = new Twig_SimpleFunction('getViewStories', function (section, limit) {
    return news_stories::getStories(section,limit);
});
$twig->addFunction($function);
$twig->render("storyList.html");

---

GOAL:

No with that said I would like to use a custom tag like

{% get_latest_stories 2 sports %}

to call the same function as above. The new way looks nicer and is easier to follow

Answer 1

Why not fetch your stories in the controller instead of the template? This does not seem like a job for the view layer...

So, something like this:

$twig->render("storyList.html", array(
    'stories' => news_stories::getStories($section, $limit)
));

Then, you'll have a stories variable available in your template.
