[SOLVED] Passing PHP global variables via Twig/Timber

Passing PHP global variables via Twig/Timber

According to https://stackoverflow.com/a/19554524/6450661, standard Twig provides a method via {{ app.request }} that I can use to pass $_GET, $_POST, $_SESSION, etc. variables.

Using Timber, is there a similar method? I can use Timber\URLHelper's get_params() method to access $_GET variables, but that's about all I can seem to find.

Solution

I looked through the source code and at least found the answer for $_GET and $_POST variables, so here it is if it helps anyone.

To access $_POST variables, use this:

{{ request.post.name_of_var }}

To access $_GET variables, use this:

{{ request.get.name_of_var }}

Update 2025: This answer became obsolete for me with the release of Timber 2.x, so if it isn't working for you, you'll need to add these variables to your context in your PHP template:

if ( ! empty($_GET) ) $context['request']['get'] = $_GET;
if ( ! empty($_POST) ) $context['request']['post'] = $_POST;

You can of course also add any other globals you need as well.

If you need them on every page, you can universally add your variables in your theme's functions.php file:

add_filter( 'timber/context', 'add_to_context' );
function add_to_context( $context ) {
    if ( ! empty($_GET) ) $context['request']['get'] = $_GET;
    if ( ! empty($_POST) ) $context['request']['post'] = $_POST;
    return $context;
}
