Changes the current user by ID or name.

Contents

Description

Set $id to null and specify a name if you do not know a user’s ID.

    Note that setting the current user does not log in that user. This example will set the current user and log them in. 

    $user_id = 12345;
$user = get_user_by( 'id', $user_id ); 
if( $user ) {
	wp_set_current_user( $user_id, $user->user_login );
	wp_set_auth_cookie( $user_id );
	do_action( 'wp_login', $user->user_login, $user );

    Attention!
    Running this function will affect everything related to the current(real) user, after it. You must restore the real user:

    $original_user_id = get_current_user_id(); // For example the real user ID is 7
wp_set_current_user( 15 );

// get_current_user_id() now returns 15
// Do other stuff here...
// ...
// get_current_user_id() still returns 15

// Restore the original user.
wp_set_current_user( $original_user_id );

// get_current_user_id() now returns 7

You must log in before being able to contribute a note or feedback.
