I don't know if this is the correct way to approach this, but here it goes. I'm working on Visual Composer (but could be vanilla WP), and I'm trying to implement a shortcode which generates another bunch of shortcodes. Somewhat a template shortcode.
[test title="some title"]
Could be converted to:
[another_shortcode] [title]some title[/title] [get_posts total="5"] [/another_shortcode]
Which will be further processed until the HTML is generated.
The thing that I'm trying to achieve is to tell the user to use some shortcodes which will generate a concrete Visual Composer shortcodes. This way I'm abstracting away the layout and if there are lot's of pages with a given layout they can be changed changing the shortcode.
Does make any sense? Is it doable?
