How to redirect the user to the initial page after authentication in Drupal 7?

Question

Drupal

The user is on the page. Next, he clicks on authorization. After successful authorization, he should not go to the profile, but to the initial page from which he entered the authorization.

Answer 2

I form such a link format for login. Using the token, the address of the page from which the authorization is going is substituted.
In Rules, I created a user redirect rule after login. I inserted the following php code into the URL of the rule. You need to enable php-filter.

<?php
 
  $path = $_SERVER['HTTP_REFERER'];
  if (isset($_GET['current'])) {            //if (isset($_GET['destination'])) {
    $path = $_GET['current'];             // $path = $_GET['destination'];
  }                                               // }
  echo $path;
 
?>

Below is a checkbox "Force redirect" - leave it.
The redirect works. Checked.
