Creating my first twig extension to provide global variables to base templates

Question

I need to populate a variable with some HTML code and make it available to my base.html.twig file.

To achive this I have made a twig extension. This is my first time

Answer 1

You want to set a global variable, not a function.

Just use getGlobals and return your variable:

class GlobalFooterExtension extends \Twig_Extension
{
    public function getGlobals()
    {
        return array(
            "GlobalFooter" => file_get_contents('http://mysite.co.uk/footer/footer.html.twig'),
        );
    }

    public function getName()
    {
        return 'GlobalFooter_extention';
    }
}

Or, if you want to lazy load the value of the variable, create a function and change your template to:

{{ GlobalFooter() }}

Besides this, if the footer file is on the same site, it's better to use the {% include '...' %} tag.

Answer 2

rename function getFilters to getFunctions
