Wordpress - shortcode for external permalink

Question

Hi folks maybe someone can help me. It does not work and I've already tried everything

This should be the shortcode:

[permalink url="http://www.domain.com/" linktext="My Link Text"]

And that the associated function:

function external_permalink( $atts ) {
  $atts = shortcode_atts( array(
    'linktext' => '',
  ), $atts, 'permalink' );

   $url = get_permalink( array(
     'url' => '',
     'target' => 'self'
  ), $url, 'url' );

  return '<a href="' . $url['url'] . '">' . $atts['linktext'] . '</a>'; }
add_shortcode('permalink', 'external_permalink');

Answer 1

I have no idea why you even have get_permalink because it shouldn't be there. This should work

function external_permalink($atts)
{
    $atts = shortcode_atts(array(
        'linktext' => '',
        'url' => ''
            ), $atts);

    return '<a href="' . $atts['linktext'] . '" rel="nofollow">' . $atts['linktext'] . '</a>';
}

add_shortcode('permalink', 'external_permalink');
