  hero_style is a custom field with web address added by user, when that web address is available it displays the button.
  I need it to not show the button if there is no inputed web address?

  function custom_field() {
  global $post;
  $url = get_post_meta( $post->ID, ‘hero_style’, true );
  echo ‘My Button‘;
  }
  add_filter( ‘field’, ‘custom_field’ );

  The blog I need help with is: (visible only to logged in users)
