How to get users id when entering their page link-CodePudding

I am now trying to create a profile page for the user and in this link the following appears

example.com/profile/peter

profile = page name

peter = username

But I also want when Peter sends The link at the top with his username shows Peter's information, not the current user's information

I want to get ID Peter when I enter the page so that I can extract his information inside that page D:

CodePudding user response：

Your question is not fully completed, and not sure how did you make your login authentication. But if I understand you, you want to get User ID from link? Than use $_GET.
Example:

example.com/profile/id=1

    /**
     * Return the id. In this case it is going to return 1
     */
    public function getId(): int 
    {

     // This is going to get the ID from the bar, which is 1 
     $userId = $_GET['id']
 
     return $userId; 
    }

CodePudding user response：

As much as i understand you want the ID of the user of current user page. if you have author.php in your theme you can add this code in there

if( get_query_var( 'author_name' ) )  {
    $current_author = get_user_by( 'slug', get_query_var( 'author_name' ) );
} else {
    $current_author = get_userdata( get_query_var( 'author' ) );
}
  $current_author_id = $current_author->ID;

CodePudding user response：

variable user_id = the id inside url

this code only works if the ID inside the url in the following form ( profile?id=1 )

if (isset($_GET['id'])) {
$user_id = $_GET['id'];
}
echo $user_id;
