Title: Add comments functionality to taxonomy.php Last modified: August 20, 2016 --- # Add comments functionality to taxonomy.php * [javiecastillo](https://wordpress.org/support/users/javiecastillo/) * (@javiecastillo) * [14 years, 6 months ago](https://wordpress.org/support/topic/add-comments-functionality-to-taxonomyphp/) * Hi all, * Hopefully someone can help me out with this — * I’m trying to add comments to the taxonomy page. Currently, immediately following the loop, I have added this code: * ``` ``` * Based on what I found on [this thread](http://wordpress.org/support/topic/how-to-add-comments-to-a-page?replies=9) and [this codex reference](http://codex.wordpress.org/Include_Tags#The_Comments_Template). * It doesn’t seem to be working. [Here is page on the site](http://www.frecklespots.com/product-categories/men/) that I am working on. * I have custom post types (products) displayed by a custom taxonomy (product categories). * Do comments even work on dynamically generated taxonomy pages? Or would I have to create custom page templates or something? My client needs to be able to create pages on the fly, and I figured using the taxonomy.php template would work best… * Thanks in advance for the help!

I hope this bumps it up. * I know it’s possible to leave comments underneath category sections, so there must be a way to make it work the same for the similar Taxonomy.php. I wonder if there is some way to signal that the taxonomy should support comments, analogous to how you would with a custom post type? * [jmkprime](https://wordpress.org/support/users/jmkprime/) * (@jmkprime) * [14 years, 3 months ago](https://wordpress.org/support/topic/add-comments-functionality-to-taxonomyphp/#post-2417555) * I was looking to do something similar. I haven’t solved it yet, but I did do some digging into the comments table. It appears that each comment is bound to an object in the wp_posts table. So I can see how comments can be added to any post inside a loop (whether its on a single page of not), but I can’t see how comments can be added when outside the loop — unless a specific post_id is supplied to bind them to. * Theoretically it would be possible to create a hidden post type which mirrored the taxonomy terms. Any comments on a dynamic term page would then be bound to the equivalent instance of the hidden post type. It’s not something I’ve tried yet; I’m still hoping for an easier solution to present itself. * Moderator [keesiemeijer](https://wordpress.org/support/users/keesiemeijer/) * (@keesiemeijer) * [14 years, 3 months ago](https://wordpress.org/support/topic/add-comments-functionality-to-taxonomyphp/#post-2417556) * comments_template(); needs the global $post object from a single Post or Page. The post object is not transferred when calling this function from another loop. Try setting $withcomments to true inside a loop: * ``` ``` * Or try it with an include (inside the loop): * ``` ``` * > When a file is included, the code it contains inherits the variable scope of > the line on which the include occurs. * [http://php.net/manual/en/function.include.php](http://php.net/manual/en/function.include.php) * [jmkprime](https://wordpress.org/support/users/jmkprime/) * (@jmkprime) * [14 years, 3 months ago](https://wordpress.org/support/topic/add-comments-functionality-to-taxonomyphp/#post-2417559) * I think I may have something. Following my idea above and keesiemeijer’s point about the comments_template needing a $post object. The methodology is 1. Create a new hidden custom post-type to which the comments are bound. 2. Provide for basic post instance creation. 3. By default the comments for will loop back to the post-types default url and not the referring page. Therefore we need to provide filters for get_comments_link. 4. A wp_rewrite rule addition is needed to deal with paged comments 5. Minimal wrapper to comments_template * The key is creating some sort of deterministic link between a single term and a single post. The following is a proof of concept. * ``` define( 'CAW_TYPE', 'caw_stubb' ); //ACTIONS add_action( 'init', 'caw_init', 100); //FILTERS add_filter( 'get_comment_link', 'caw_comment_link', 1, 3 ); //INIT Function -- setup post type and wp_rewrite riles function caw_init() { $singular = 'Comments Stub'; $plural = 'Comments Stubs'; $args = array( 'label' => $plural, 'labels' => array( 'name' => $plural, 'singular_name' => $singular, 'add_new' => 'Add '.$singular, 'add_new_item' => 'Add New '.$singular, 'edit_item' => 'Edit '.$singular, 'new_item' => 'New '.$singular, 'view_item' => 'View '.$singular, 'search_items' => 'Search '.$plural, 'not_found' => 'No '.$singular.' found', 'not_found_in_trash' => 'No '.$singular.' found in Trash', 'parent_item_colon' => $singular.': ' ), 'description' => 'Hidden post type used to bind any comment to', 'public' => false, 'capability_type' => 'post', 'supports' => array( 'title', 'trackbacks', 'custom-fields', 'comments' ), 'query_var' => false ); register_post_type( CAW_TYPE, $args ); caw_add_rewrite_rules($rules); } //ADD wp_rewrite rules for all public taxonomies function caw_add_rewrite_rules($rules) { $taxes = get_taxonomies( array(), 'objects'); foreach ( $taxes as $tax ) { if ( $tax->public ) { add_rewrite_rule( $tax->rewrite['slug'].'/([^/]+)/comment-page-([0-9]{1,})/?$', 'index.php?'.$tax->query_var.'=$matches[1]&cpage=$matches[2]', 'top'); } } flush_rewrite_rules(); } //FILTER get_comments_link to redirect from the hidden post types uri to the uri //uri of the dynamically generated term page. function caw_comment_link($link,$comment,$var) { global $post; if ( get_post_type() == CAW_TYPE ) { $meta = get_post_custom(); $postlink = get_permalink($comment_post_ID); $termlink = get_term_link( intval($meta['caw_term_id'][0]), $meta['caw_taxonomy'][0] ); $link = str_replace( $postlink, $termlink, $link ); } return $link; } //RETURN the hidden post associated with a specific term object. Optionally //create that post if it does not already exist function caw_getstubb_term($term, $create=true) { $oldposts = get_posts( array( 'name' => $term->taxonomy.'-'.$term->term_id, 'post_type' => CAW_TYPE )); if ( count($oldposts) == 1 ) { return $oldposts[0]; } elseif ( $create) { $newpostid = caw_addstubb_term($term); if ( !is_wp_error($newpost) ) { return get_post($newpost); } else { return false; } } else { return false; } } //CREATE hiiden post associated with a specific term object. Record the parent term using //the post custom fields function caw_addstubb_term($term) { $newpost = wp_insert_post( array( 'post_title' => $term->name, 'post_name' => $term->taxonomy.'-'.$term->term_id, 'post_status' => 'publish', 'post_type' => CAW_TYPE ) ); add_post_meta($newpost->ID, 'caw_taxonomy', $term->taxonomy, true); add_post_meta($newpost->ID, 'caw_term_id', $term->term_id, true); return $newpost; } //DISPLAY COMMENTS function. Retrieves hidden post & runs comments_template. // $file and $seperate are passed directly to comments_template. function caw_comments_template($term, $file='', $seperate=true, $create=true) { global $post, $withcomments; if ( isset($post) ) $oldpost = $post; $post = caw_getstubb_term($term, $create); $withcomments = "1"; comments_template( $file, $seperate); if ( isset($oldpost) ) $post = $oldpost; } ``` * This is still very generic as it adds the possibility of comments on all public taxonomies. Ideally the creation of the hidden posts would be hooked into the creation/deletion of the original terms. However, I had to do this for a site redesign where those terms were already in existence. * [ACCOUNT-ABANDONED](https://wordpress.org/support/users/kraterdesign/) * (@kraterdesign) * [13 years, 11 months ago](https://wordpress.org/support/topic/add-comments-functionality-to-taxonomyphp/#post-2417580) * Thanks a ton, jmkprime! Awesome. I made a few modifications, because I ran into some errors and the url rewrite didn’t work for me, but now it works a treat. * The reason I renamed ‘caw’ to ‘taxcom’ is for no other reason than that ‘caw’ didn’t mean anything to me. * _[Code moderated as per the [Forum Rules](http://codex.wordpress.org/Forum_Welcome#Posting_Code).
