How to display comments list by order when clicking on newest or oldest link?

Question

0 down vote favorite

I have a wordpress single post where I have comment system - Live Site

And I have two links one is: 1. newest 2. oldest

The thing I want is when I will click on newest it will display the comments list in newest order and if I click on oldest it will display the comments list from oldest to newest.

Any simple solution is fine (though I prefer using ajax but no need for ajax right now). GET and POST method will be fine.

Any clue?

Thanks in adavance

Just open the comments.php file from your theme. Find the following line (or similar)

<?php foreach ($comments as $comment) : ?>

Add this lines just above it

if (isset($_GET['comOrder']) && $_GET['comOrder'] == 'Newest' )
    $comments = array_reverse($comments, true);

so your code looks like this:

<?php if (isset($_GET['comOrder']) && $_GET['comOrder'] == 'Newest' )
        $comments = array_reverse($comments, true);
foreach ($comments as $comment) : ?>

and then make sure your newest first like points to your current location with ?comOrder=Newest

UPDATE:

In case you are using wp_list_comments then simply add reverse_top_level parameter set to true when newest first link is clicked so something like this should work:

$args = array('type' =>'comments','callback' => 'mytheme_comment');
if (isset($_GET['comOrder']) && $_GET['comOrder'] == 'Newest' )
    $args['reverse_top_level'] = true;
wp_list_comments($args);
