Twig template cannot include php template

Question

I encountered a problem, which for me is quite not clear and hard to understand. I have tried to make calendar widget, which is supposed to be display on every page on my si

Answer 1

NOTE: snippets below are totally non-tested.

http://twig.sensiolabs.org/doc/functions/date.html

The function date seems to create \DateTime object.

{% set now = date() %}
{% set offset = date(now.format('Y/m/01')).format(w) %} {# weekday of 1st day #}
{% set number = now.format('t') %} {# days in month #}
{% set koniec = 7 - ((offset + number) % 7) %}
{% set aktualny = now.format('n') %} {# today #}

However, if you wants to include original php file (say 'calendar.php') in twig, you have to write extension to get it work.

class CalendarExtension extends \Twig_Extension
{
    private $pathToPhp; //store that where the php file is

    public function setPhpFile($pathToPhp)
    {
        $this->pathToPhp = $pathToPhp;
    }

    public function getFunctions()
    {
        return array(
            new \Twig_SimpleFunction('calendar', array($this, 'showCalendar'))
        );
    }

    public function showCalendar([put arguments here if you need])
    {
        ob_start();
        include ($this->pathToPhp);
        return ob_get_clean();
    }
}

To make above work, you should create "tagged" service in container.

in app/config/config.yml

services:
    calendar_twig_extension:
        class: __Namespace__\CalendarExtension
        calls:
            - [setPhpFile, [__path to your calendar.php__]]
        tags:
            - [name: twig.extension]

words that double-underscored should be replaced:

• _ _ Namespace _ _ : Namespace of CalendarExtension
• _ _ path to your calendar.php _ _ : full path to your calendar.php. You can use parameters like %kernel.root_dir% and so on to manage your path project-relative.

With these, you finally can simply write

{{ calendar([arguments for CalendarExtension::showCalendar]) }}
