Multiple level shortcodes

Question

I am working on a plugin and stopped in a situation, I hopesomeone can help me with a solution.

I want to have a shortcode structure like :

[shortcode_1]
[shortcode_2]
[shortcode_3]
[shortcode_4][/shortcode_4]
[/shortcode_3]
[/shortcode_2]
[/shortcode_1]

But if I use add_shortcode, only first shortcode works...

Is there any way to have a shortcode structure like this ?

Thanks

Try passing the content of each shortcode through apply_filters( 'the_content', $content ); - you may not be getting your shortcode output because it's never being called in the first place (beyond the top level). the_content filter include do_shortcode() (from memory), which is what you need. See how it goes...
