add comment bar in custom weight & area

Hi ilyas6462,
Have you tried to use the default comment loader function:

<?php comments_template(); ?>

Make sure you don’t load wpDiscuz more than one time on the same page, wpDiscuz doesn’t support multiple comment boxes on same page.

Another way to call wpDiscuz file using this PHP script:

if(file_exists(ABSPATH . 'wp-content/plugins/wpdiscuz/templates/comment/comment-form.php')){
	include_once ABSPATH . 'wp-content/plugins/wpdiscuz/templates/comment/comment-form.php';
}

& html short code?

actully i want can add comment bar in “visual composer” via html short code too ?

wpDiscuz doesn’t have shordcode

can you tell me solution ? which plugin you can recommended ? & how you can add this features ?

Ok, try this.
Put this code in current theme functions.php

function my_wpdiscuz_shordcode() {
	if(file_exists(ABSPATH . 'wp-content/plugins/wpdiscuz/templates/comment/comment-form.php')){
		include_once ABSPATH . 'wp-content/plugins/wpdiscuz/templates/comment/comment-form.php';
	}
}
add_shortcode( 'wpdiscuz_comments', 'my_wpdiscuz_shordcode' );

and try to use this shordcode: [wpdiscuz_comments]

Please note: WordPress Comment system is designed to be loaded on single post/page, it’s not designed for archive pages like Categories, Tags, Author, Search, etc… So make sure you don’t load widget with this shordcode on non-single (archive) pages.
