I'm importing posts from a Drupal feed that uses <!--break--> instead of <!--more-->. I'm thinking that I could scan the content and replace all instances of <!--break--> with <!--more-> from my functions php, but it seems like there would be an easier way to make the function that is already looking for <!--more--> validate and trigger off of <!--break--> as well. Any ideas or other innovative ways that I can trigger the page break from <!--break--> in Wordpress?
You can just modify the existing function. open up the wp-includes/post.php file. Find the get_extended function and replace
if ( preg_match('/<!--more(.*?)?-->/', $post, $matches) ) {
with
if ( preg_match('/<!--more(.*?)?-->/', $post, $matches) || preg_match('/<!--break(.*?)?-->/', $post, $matches) ) {
