A website has 300 products and all with do-follow. I need to make them all no-follow and future links as well, but only if the links are inside the productloop.
This code generates for the entire site. How Would I do it specifically to the woocommerce product?
add_filter('the_content', 'my_nofollow');
add_filter('the_excerpt', 'my_nofollow');
function my_nofollow($content) {
return preg_replace_callback('/<a[^>]+/', 'my_nofollow_callback', $content);
}
function my_nofollow_callback($matches) {
$link = $matches[0];
$site_link = get_bloginfo('url');
if (strpos($link, 'rel') === false) {
$link = preg_replace("%(href=\S(?!$site_link))%i", 'rel="nofollow" $1', $link);
} elseif (preg_match("%href=\S(?!$site_link)%i", $link)) {
$link = preg_replace('/rel=\S(?!nofollow)\S*/i', 'rel="nofollow"', $link);
}
return $link;
}
