Did you ever want a quick way to print a nice footer with the copyright in years?

Here’s a shortcode for that! Put it in your themes functions.php and use anywhere!

add_shortcode('copyright-year', function($atts, $content)
{
    extract(shortcode_atts(array(
        'sign' => 'true',
        'start' => '',
    ), $atts));

    $current_year = date('Y');
    $print_sign = ($sign === 'true') ? '©' : '';

    if($start === $current_year || $start === '')
        return "{$print_sign} {$current_year}";
    else
        return "{$print_sign} {$start} - {$current_year}";
});
