WordPress plugin: finding the <!--more--> in the_content

Question

I'm writing a WordPress plugin that filters the_content, and I'd like to make use of the <!--more--> tag, but it appears that it has been stripped out by the time it reaches me. This appears to be not a filter, but a function of the way WordPress works.

I could of course resort to reloading the already-loaded content from the database, but that sounds like it might cause other troubles. Is there any good way for me to get the raw content without the <!--more--> removed?

Answer 1

Looks like you were answered over on WordPress.org - did that solution work for you?

Answer 2

Chances are, by the time your plugin runs, <!--more--> has been converted to <span id="more-1"></span>

This is what I use in my plugin, which injects some markup immediately after the <!--more--> tag:

add_filter('the_content', 'inject_content_filter', 999);

function inject_content_filter($content) {
  $myMarkup = "my markup here<br>";
  $content = preg_replace('/<span id\=\"(more\-\d+)"><\/span>/', '<span id="\1"></span>'."\n\n". $myMarkup ."\n\n", $content);
  return $content;
}
