Question

How can I get the current URL from a Twig template?

I am using Twig with PHP, without any other framework.

Finding the current URL

The current URL is supplied by your web server and written to the $_SERVER super-global. Run this small script, <?php echo '<pre>'; print_r($_SERVER);, through your server and root around to find the value(s) you are looking for.

Getting the URL in TWIG

After you have the URL, you need to pass it as a template variable when calling render(...) on the Twig template instance. For example, you might code this.

$current_url = // figure out what the current url is

// pass the current URL as a variable to the template
echo $template->render(array('current_url' => $current_url));

To use the variable in the template, you use the {{ variable_name }} syntax.
