Here is a Regex for extracting URLs from text. However, these links will not already be hyperlinked or source attribtues from images or iframes.
This example is in PHP. I was trying to format a Wordpress page to auto hyperlink but preserve embeded images, iframes, etc.
Wordpress does some funky stuff w/ regard to formatting, which is why I ended up going with the
nl2br function and then removing double instances.
A little hacky but it seems to work.
<?php $regex = '~^http(.*?)(?=[\<])~im'; $content = nl2br(get_the_content()); $content = preg_replace($regex, '<a href="$0" target="_blank">$0</a>', $content); $html = nl2br(html_entity_decode(esc_html($content))); $html = str_replace('<br /><br />', '<br/>', $html); echo $html;
