How do I write the wordpress function “is_front_page()” in twig Timber code?

1. Timber comes with the fn (also has alias of function) that let’s you execute external PHP functions. So something like this would work:

   {% if fn('is_front_page') %}
     Homepage content
   {% endif %}
   

2. I like to keep special functions outside of my twig templates. In Timber you can define your own context where you can set your own variables.

   Create a file called front-page.php and add:

   <?php
   
   $context = Timber::get_context();
   
   // Set a home page variable
   $context['is_front_page'] = 'true';
   
   Timber::render(array('home.twig'), $context);
   

   then you can use is_front_page as a variable just like you wanted:

   {% if is_front_page %}
    Homepage content
   {% endif %}
   

3. You can create a global content by extending the timber_context fitler.

   Add the below into you functions.php file and it will add to all templates using calling Timber::get_context();.

   add_filter('timber_context', 'add_to_context');
   function add_to_context($context){
       /* Add to Timber's global context */
       $context['is_front_page'] = is_front_page();
       return $context;
   }
