How To Add Comments Function Inside Shortcode In Theme

Hello,

I’m trying add the comments area of my posts to a tab by using a tab plugin.

I’m using the following code which was provided by the plugin developer in my template file to accomplish this, but I can seem to figure out how to add a function inside this shortcode code.

<?php
do_shortcode("[tab name='Tab 1']{$content}[/tab]");
do_shortcode("[tab name='Tab 2']{$serviceInfo}[/tab]");
do_shortcode("[tab name='Tab 3']Condolences Here[/tab]");
echo do_shortcode('[end_tabset]');
?>

The 3rd line is giving me the trouble. Instead of “Condolences Here” I’d like to add the comments_template() function to the 3rd line so my comments appear on the 3rd tab. However it doesn’t work. I want it to look something like this:

do_shortcode("[tab name='Tab 3']comments_template()[/tab]");

I can’t figure out how to allow this php function inside the do_shortcode function.

Thanks for the help!
