There are a few ways to get the current URL in Drupal 7. First, we can get the $_GET[‘q’] by the current_path() function. But it will ignore the language prefix if you are working on a multilingual site.

Examples of current_path():

http://example.com/node/306

returns “node/306”

http://example.com/drupalfolder/node/306

returns “node/306” while base_path() returns “/drupalfolder/”

http://example.com/path/alias

returns internal path such as “node/306” as opposed to the path alias

http://example.com/en/path/alias

returns internal path such as “node/306” as opposed to the path alias and language prefix is ignored

There is also another function called request_path() which may also help you to get the current path with language prefix.

Examples of request_path():

http://example.com/node/306

returns “node/306”

http://example.com/drupalfolder/node/306

returns “node/306” while base_path() returns “/drupalfolder/”

http://example.com/path/alias

returns “path/alias” as opposed to the internal path

http://example.com/en/path/alias

returns en/path/alias

http://example.com/index.php

returns an empty string (meaning: front page)

http://example.com/index.php?page=1

returns an empty string

Another function to get the current URL is request_uri() which returns the $_SERVER[‘REQUEST_URI’] value.
