The comments template is added to template files via the comments_template() template tag. The comments_template() template tag includes the comments.php template-part file. The comments.php template-part file includes the comment-reply form via the comment_form() template tag. Refer to the Codex (linked) for detailed instructions for modifying the content and output of comment_form().
You could export all of the posts from your old site, including comments. Then, import them into your new site and delete the posts you don’t want. This will preserve all of the links between posts and comments.
Yay! We got filters! Wrapping the result of the $wpdb comments query right into a filter callback (and a plugin) is the nice way of handling comments. /* Plugin Name: »Kaisers« Comments without admin comments */ ! defined( ‘ABSPATH’ ) AND exit; add_filter( ‘comments_array’, ‘wpse_61072_comments_without_admin’, 20, 2 ); function wpse_61072_comments_without_admin( $comments, $post_id ) { foreach … Read more
From quick look at core that would probably be get_option(‘comments_per_page’). However WP functions just use this internally, why not just let them take care of it? You are not describing why do you need to handle this directly.
There are two special filters for that: add_filter( ‘previous_comments_link_attributes’, ‘wpse_77217_comment_nofollow’ ); add_filter( ‘next_comments_link_attributes’, ‘wpse_77217_comment_nofollow’ ); function wpse_77217_comment_nofollow() { return ‘ rel=”nofollow”‘; }
The cookies are fine. The secret is caching. The blog owner has set up a server side output caching that doesn’t stop when someone sends as cookie. It should – as you can see, because caching pages with personal data is … odd. Lesson: Don’t cache personalized output.
You should not edit the WordPress core files! If you have comment_id_fields() in your comments template, like this: <p class=”form-submit”> <input name=”submit” type=”submit” id=”<?php echo esc_attr( $args[‘id_submit’] ); ?>” value=”<?php echo esc_attr( $args[‘label_submit’] ); ?>” /> <?php comment_id_fields( $post_id ); ?> </p> you might use: add_filter(“comment_id_fields”,”my_submit_comment_message”); function my_submit_comment_message($result){ return $result.” <span>(your message will only be … Read more
The filter you’re looking for is manage_edit-comments_columns. Here is a post detailing how to add custom columns to the edit comments section of the admin http://stv.whtly.com/2011/07/27/adding-custom-columns-to-the-wordpress-comments-admin-page/
If you use wp-comments-post.php it would be better to customize comment_form by hook comment_form_default_fields, I don’t know why you create the new one. But as per of your functions you can handle it like this add_filter( ‘preprocess_comment’, ‘verify_comment_meta_data’, 1, 1 ); function verify_comment_meta_data( $commentdata ) { $commentdata[‘review_title’] = ( ! empty ( $_POST[‘review_title’] ) ) … Read more
Just some additional info for the main comment query: Since you mentioned the global $wp_query object, we can see that it stores: $wp_query->max_num_comment_pages = $comment_query->max_num_pages; in the main comment query in the comments template. There exists a wrapper for this, namely: get_comment_pages_count(); that’s available after the main comment query. If we need it before the … Read more
