您可以将消息保存在$_SESSION 变量这样，将保留这些值，直到您决定再次删除它们为止。

function save_message( $type, $message = \'\' ) {
    $_SESSION[\'messages\'][$type] = $message;
}

function get_messages() {
    $return = \'\';

    if ( isset( $_SESSION[\'messages\'] ) && is_array( $_SESSION[\'messages\'] ) ) {
        foreach( $_SESSION[\'messages\'] as $type => $message ) {
            $return .= sprintf( \'<p class="%1$s">%2$s</p>\', $type, $message );
        }
    }

    if ( strlen( $return ) > 0 )
        return $return;

    return false;
}

function clean_messages( $type = false ) {
    if ( ! $type )
        $_SESSION[\'messages\'] = array();

    else
        unset( $_SESSION[\'messages\'][$type];
}

save_message( \'success\', __( \'You have successfully Login.\', \'frontendprofile\' ) );

if ( $messages = get_messages() ) {
    echo $messages;

    clean_message(\'success\');
}
