Activate and Login user after registration Gravity Form - wordpress

Question

I wanted to automatically activate and login user after registration on my site using gravityform is there a way?
.I did some research and currently some of the guides are outdated.I tried this code,currently its not working
function autologin($user_id, $config, $entry, $password) {
wp_set_auth_cookie($user_id, false, '');
}
add_action("gform_user_registered", "autologin", 10, 4);

Answer 1

This checks if the user is logged in or not. If not, they will auto-login upon form submission.
/**
* Auto login after registration if not logged in.
*/
function ip_gravity_registration_autologin( $user_id, $user_config, $entry, $password ) {
// Only automatically login if we aren't *already* logged in
if ( ! is_user_logged_in() ) {
// Get the user data (for the login)
$user = get_userdata( $user_id );
// Sign the user in
wp_signon( array(
'user_login' => $user->user_login,
'user_password' => $password,
'remember' => false, // Don't set the remember cookie
));
}
}
add_action( 'gform_user_registered', 'ip_gravity_registration_autologin', 10, 4 );

Did you try this?
function pi_gravity_registration_autologin( $user_id, $user_config, $entry, $password ) {
$user = get_userdata( $user_id );
$user_login = $user->user_login;
$user_password = $password;
wp_signon( array(
'user_login' => $user_login,
'user_password' => $user_password,
'remember' => false
), false );
wp_set_current_user( $user_id, $user_login );
wp_set_auth_cookie( $user_id, true, false );
do_action( 'wp_login', $user_login );
}

Here's a modified version of the code from my Gravity Forms Auto Login plugin that handles this.
add_action( 'gform_user_registered', 'gw_auto_login', 10, 4 );
function gw_auto_login( $user_id, $feed, $entry, $password ) {
$user = new WP_User( $user_id );
$user_data = array(
'user_login' => $user->user_login,
'user_password' => $password,
'remember' => false
);
$result = wp_signon( $user_data );
if( ! is_wp_error( $result ) ) {
global $current_user;
$current_user = $result;
}
}
The plugin accounts for many other Gravity Forms scenarios that might interfere with automatically logging the user in.
