Hi Brajesh
here’ the reply from the people at Bimber:

Hi,

The $user is a WP_User object returned, on success, from wp_signon() function.

Below the full code of that function:

function snax_ajax_login() {
$credentials = array();
$credentials[‘user_login’] = filter_input( INPUT_POST, ‘log’, FILTER_SANITIZE_STRING );
$credentials[‘user_password’] = filter_input( INPUT_POST, ‘pwd’, FILTER_SANITIZE_STRING );
$credentials[‘remember’] = filter_input( INPUT_POST, ‘rememberme’, FILTER_SANITIZE_STRING );
// Verify reCaptcha.
$use_recaptcha = snax_is_recatpcha_enabled_for_login_form();
if ( $use_recaptcha ) {
$recaptcha_token = filter_input( INPUT_POST, ‘g-recaptcha-response’, FILTER_SANITIZE_STRING );
$recaptcha_valid = snax_verify_recaptcha( $recaptcha_token );
if ( ! $recaptcha_valid ) {
snax_ajax_response_error( snax_get_recaptcha_invalid_message() );
exit;
}
}
$secure_cookie = is_ssl();
$user = wp_signon( $credentials, $secure_cookie );
if ( is_wp_error( $user ) ) {
$message = $user->get_error_message();
snax_ajax_response_error( $message );
exit;
}
$redirect_url = filter_input( INPUT_POST, ‘redirect_to’, FILTER_SANITIZE_STRING );
$redirect_url = apply_filters( ‘snax_login_redirect_url’, $redirect_url, $user );
// Strip snax vars.
$redirect_url = preg_replace( ‘/?’ . snax_get_login_popup_url_variable() . ‘.*/’, ”, $redirect_url );
$redirect_url = preg_replace( ‘/’ . snax_get_login_popup_url_variable() . ‘.*/’, ”, $redirect_url );
$response_args = array(
‘redirect_url’ => $redirect_url,
);
snax_ajax_response_success( ‘Log in successfull’, $response_args );
exit;
}
