story.php

It gets the ID or title and reads the data from the database.

 $link->read();

It uses assign to pass down values to the template For story.php, It is going to use story_center as the main center body

 $main_smarty->assign('tpl_center', $the_template . '/story_center'); 
 $main_smarty->display($the_template . '/pligg.tpl');

If you look at pligg.tpl, it is the basic layout of the whole page. It has {include file="$tpl_center.tpl"} which will include the body of the page.
In the case of story.php it will be story_center.tpl.

story_center.tpl

 $link->print_summary();

What this does it print the main text of the story (This will be covered in another text)
Further down the page you will see

 get_comments();

This is what prints all the comments in story.php
get_comments is declared in story.php, so back we go.

story.php

get_comments will retrieve all the comments which are the parent. It prints the parent first using $comment->print_summary($link); And then it finds all the comments that replied to the parent comment, and prints them using $comment->print_summary($link);
So we have

Parent Comment
-Child comment
-Child comment
-Child comment

Parent Comment
-Child comment
-Child comment

$comment->print_summary is declared in /libs/comment.php

/libs/comment.php

It reads the comment from the database using the $link that is passed from story.php

 if(!$this->read) return;

It assigns the values from the database to variables so they can be accessed by the template

 $smarty->assign('comment_id', $this->id);
 $smarty->assign('comment_author', $this->author);
 $smarty->assign('comment_link', $this->link);

Then it displays the comment using

 $smarty->display($the_template . '/comment_show.tpl');

Overview

Pligg.tpl is the main layout.
Story_center.tpl is the story layout which prints the story, get_comments, and shows the comment form
Comment_show.tpl is the layout of an individual comment.
