Unfortunately the hooks: manage_{$this->screen->id}_columns manage_{$this->screen->id}_sortable_columns manage_comments_custom_column are not available for the post-comments list table, constructed within the wp_ajax_get-comments call. That table consists only of two columns: author and comment. The data for author, avatar, email, url and IP is displayed in the first column. We can on the other hand use a hack like: add_filter( … Read more
By default WordPress organizes the comment pages from oldest to newest. This does not change, even if the Settings-Discussion options have been modified.

These settings, basically, define comment order in the default comment loop, and what page … Read more
Don’t build your own form and don’t modify comments.php – it’s purpose is little bit different and I don’t think you should include it inside sidebar. Just put comment_form function call in your sidebar template. It takes 2 parameters: args and post_id. So you can do it like this: $args = array( … // your … Read more

The visual representation of a comment form (or lack of it) do not have any impact on the ability to receive comments, and spammers usually don’t care at all what is in your form. WordPress have a well publicized end point to which all comments are being sent (and while I don’t remember the detail … Read more
I can think of only following ways to achieve this. There is a filter “comments_open” that check if the post whose $post_id is provided has comments open. You can use that to return false. There is another filter “comments_template” that return the template file to be used to display comment form. You can return an … Read more
Open comments.php file inside your theme’s folder <?php if ( comments_open() ) : ?> <?php $fields = array( ‘author’ => ‘<p class=”comment-form-author”>’ . ‘<label for=”author”>’ . __( ‘Name’, ‘responsive’ ) . ‘</label> ‘ . ( $req ? ‘<span class=”required”>*</span>’ : ” ) . ‘<input id=”author” name=”author” type=”text” value=”‘ . esc_attr( $commenter[‘comment_author’] ) . ‘” size=”30″ … Read more
I wonder if you mean this kind of approach: add_filter( ‘init’, function() { $u = wp_get_current_user(); if( $u->exists() && in_array( ‘banned’, $u->roles, true ) ) add_filter( ‘comments_open’, ‘__return_false’ ); } ); where we check if the current user has the custom banned role. If that’s the case then we force all comments to be closed … Read more
Filter comment_form_defaults and add your code to the textarea. Sample code, not tested: add_filter( ‘comment_form_defaults’, ‘wpse_120049_extend_textarea’ ); function wpse_120049_extend_textarea( $args ) { $args[‘comment_field’] .= ‘<p>Extra text.</p>’; return $args; }
