Customization of wpdiscuz-comment-plugin

Posted by: @dmendiratta

1) Can we integrate the plugin with a custom table?

I'm really sorry, but there is no way to do this. 

2) Can we load comments with ajax if we do it with shortcode?

You can use the code provided by Taron in this post:

I have same problem as Mr. @dmendiratta 
Will this code work? Please confirm! 

<?php
/**
* WPDISCUZ Plugin shortcode
*/
function my_wpdiscuz_shortcode() {
$html = "";
if (file_exists(ABSPATH . "wp-content/plugins/wpdiscuz/themes/default/comment-form.php")) {
ob_start();
include_once ABSPATH . "wp-content/plugins/wpdiscuz/themes/default/comment-form.php";
$html = ob_get_clean();
}
return $html;
}
add_shortcode("wpdiscuz_comments", "my_wpdiscuz_shortcode");

/**
* Call single post by AJAX
*/
add_action('wp_ajax_playback_submit_callback','playback_submit_callback');
add_action('wp_ajax_nopriv_playback_submit_callback','playback_submit_callback');

function playback_submit_callback() {

$args = array(
'post_type' => 'playbook',
'p' => 104
);

$query = new WP_Query($args);
while ( $query->have_posts() ) {
$query->the_post();
$html = do_shortcode('[wpdiscuz_comments]');
}
wp_reset_postdata();
echo $html;
exit;
}
?>

I did the same thing but not working for me. Please look into this as soon as possible
