How to get the current viewed users uid

Question

If I am viewing a users profile page, how do I obtain and display (in a block) their uid? NOTHING to do with the current logged in user. I need to display the users id in a block on their page.

Answer 1

If you are showing a standard drupal user profile page this should get you going:

  $user = user_load(arg(1));
  $user->uid; // access user id

This assumes the path is user/uid. If your path looks different adjust the arg(position_in_path) to your needs.

Answer 2

A better option would be to use template_preprocess_user_profile(&$variables) and add the user id from here - that way you're not relying on any URL arguments (arg() is a recipe for fail).

Pop the following in your template.php

function MYTHEME_preprocess_user_profile(&$variables) {

  $account = $variables['elements']['#account'];
  //Add the user ID into the user profile as a variable
  $variables['user_id'] = $account->uid;
  // Helpful $user_profile variable for templates.
  foreach (element_children($variables['elements']) as $key) {
    $variables['user_profile'][$key] = $variables['elements'][$key];
  }

  // Preprocess fields.
  field_attach_preprocess('user', $account, $variables['elements'], $variables);

}

This will make the UID available to the user-profile.tpl.php template as a variable called $user_id.

This means that you can then copy user-profile.tpl.php from the modules/user directory to your theme directory and change it to the following:

<div class="profile"<?php print $attributes; ?>>
  <?php print $user_id; ?>
  <?php print render($user_profile); ?>
</div>

Obviously you'll want to style it and add extra DIVs and whatnot, but at it's most basic this will put the user id at the top of the user profile page.

Answer 3

You can use this function menu_get_object('user')

Answer 4

probably not the best approach in drupal 8 but this work

$current_path = \Drupal::service('path.current')->getPath();
    $exploded_path= explode('/',$current_path);
    $uid=end($exploded_path);
    if (prev($exploded_path) =='user')
      $user=User::load($uid);

Answer 5

as BetaRide in the page profile you can use arg(1) it will give you user profile and then you can use user_load()
