Thank for your reply @elliot I will try this solution. I work on another solution but I do not know yet if it’s the most efficient.
My solution is as follows:
I create a “next_page” field. Whenever WordPress meets a flexible field, I increment my content in a variable $myContent.
When WordPress meets a field next_page I do this:
$myContent = "<--nextpage -->\n"
at the end of my loop I attribute $myCONTENT to the_content() and I appear like this:
global $ post;
$post-> post_content = $MyContent;
setup_postdata($post);
remove_filter('the_content', 'wpautop');
the_content();
wp_link_pages();
This works well but I do not know what it is worth in terms of performance.
Your solution looks more flexible. I would try in the coming days.
thank you very much
