when does <!–nextpage–> get processed by wordpress filtering. i am adding multiple paged posts in post content on the content_save_pre and this is good for rendering my shortcodes, but <!–nextpage–> doesnt get processed and shows up as an html comment
When does wordpress process <!–nextpage–>
I am not sure what you mean by rendering shortcodes at that stage, they are usually rendered when content is retrieved for display.
nextpage tag is processed in
setup_postdata()( source ), which is called bythe_post(). In other words – during Loop.As an update. content_save_pre does process <!–nextpage–> i had the <!–nextpage–> tag inside the shortcode function, once i moved them outside, all was good.
