Hi John,
thank you very much for the clear and huge explanation.

At the moment the important task is to solve the question of putting the flexible content into the post_content.

Actually I’m using the following solution that works very well for me. This solution is designed only for my pourposes but could be customized for other possible scenarios.

function flexible_content_to_post_content( $post_id ) {

	$post_type = 'books';

	//Check if we are saving a books post type
	if( get_post_type( $post_id ) != $post_type)
		return;

	//Check it's not an auto save routine
	if( defined('DOING_AUTOSAVE') && DOING_AUTOSAVE ) 
		return;

	//The Post Content
	$post_content = '';
	
	//Loop the flexible content rows
	if( have_rows('flexible_content') ):
		while ( have_rows('flexible_content') ) : the_row();
		
			//TEXT BLOCK
			if( get_row_layout() == 'text_block' ):
				
				$post_content .= get_sub_field('wysiwyg');
	
			endif;
				
		endwhile;
	endif;
	
	
    //If calling wp_update_post, unhook this function so it doesn't loop infinitely
    remove_action('save_post', 'flexible_content_to_post_content');

	// call wp_update_post update, which calls save_post again. E.g:
    wp_update_post(array('ID' => $post_id, 'post_content' => $post_content));

    // re-hook this function
    add_action('save_post', 'flexible_content_to_post_content');
	
}
add_action('save_post', 'flexible_content_to_post_content');

Thanks for sharing your plugin. At the moment the solution I’ve reported above is enough easy to use for me. I don’t need to check for all acf fields within the post. I need only to check text fields (textinput, textarea, wysiwyg) inside the flexible content.

Of course I need to do some testing for large flexible fields, but considering my personal context, this should not be a problem.

Thank you very much.
