<?php

/*	 The class for displaying one or more comments.
    (There's also a function for adding a new comment to the DB because I wasn't
    sure where else to put it!).

    This works similarly to the HANSARDLIST class.

    To display all the comments for an epobject you'll do:

        $args = array ('epobject_id' => $epobject_id);
        $COMMENTLIST = new COMMENTLIST;
        $COMMENTLIST->display ('ep', $args);

    This will call the _get_data_by_ep() function which passes variables to the
    _get_comment_data() function. This gets the comments from the DB and returns
    an array of comments.

    The render() function is then called, which includes a template and
    goes through the array, displaying the comments. See the HTML comments.php
    template for the format.
    NOTE: You'll need to pass the 'body' of the comment through filter_user_input()
    and linkify() first.

    You could also just call the $COMMENTLIST->render() array with an array
    of comment data and display directly (used for previewing user input).
