Need to Modify a Wordpress Shortcode with another wordpress shortcode

Question

hi I have this shortcode... [user_meta key="_wc_social_login_profile_image" id=3] It shows the image of a particular user with a special number..

I need to change the number with another shortcode I already have... [user_special_number]

I need the final result to be...

[user_meta key="_wc_social_login_profile_image" id="[user_special_number]"]

Answer 1

You can write something like this

ob_start();
do_shortcode("[user_special_number]");
$special_id = ob_get_clean();

So now you have you your special id, so let's do it again

ob_start();
do_shortcode('[user_meta key="_wc_social_login_profile_image" id="'.$special_id.'"]');
echo ob_get_clean();
