Attributes Links on additional information

This code snippet should give the general idea:

<?php
  // code goes in functions.php for your child theme
  add_filter ('woocommerce_attribute', 'link_attributes');
  function link_attributes($att_string) {
    $atts = explode (',', $att_string);
    $att_string = '';
    foreach ($atts as $att) {
      if (strlen($att_string) > 0) {
        $att_string .= ', ';
      }
      $att = trim($att);
      $att_string .= '<a href="https://wordpress.org/">'.$att.'</a>';
    }
    return $att_string;
  }

You can put it anywhere in functions.php, though not inside a function. The “<?php” is only needed at the top.

What is the url for an attribute? Do you have an example please?

Works for me, your experience may vary.
