Solution

Well there are 2 ways of achieving this, and which one you will use depends on how your theme is made.

The first solution is if you have a foreach loop which makes the comments show.

foreach ($comments as $comment) :
    $commentType = get_comment_type();
    if($commentType == 'comment'){
        //html and functions to get the data
    }
endforeach;

The other solution is if you’re using the wp_list_comments() function to show the comments. We can pass arguments to this function, so here is how it goes.

wp_list_comments(array('type' => 'comment'));

How it works

Well it’s really simple.

In the first solution we are just using wordpress built-in function get_comment_type(); to get the type which can be “comment”, “trackback” or ‘pingback’. After that we’re just making a little if statement to check if the current one is really a comment and if it is show it, if it’s not do nothing with it.

The second solution is if you are using the wp_list_comments() function which has some advantages over a custom loop but it also have some disadvantages, more about that in a different post. This function accepts a lot of arguments, but we need only one, type. Type accepts 5 different values: ‘all’, ‘comment’, ‘trackback’, ‘pingback’, or ‘pings’(pingbacks and trackbacks together), so by passing in ‘comment’ as the type wordpress will filter all the data and show only comments.
