Wordpress: show comment on a new page?


Wordpress: show comment on a new page?



I need to display link after each comment, when you click that link, a new page displays that single coment on a new page.

Is that possible?

In WordPress how do you register built-in taxonomies with custom post types in code?
I answered your exact question over on WordPress Answers (also a StackExchange site) just yesterday.


WordPress Custom Post Types - Pretty Permalinks
You can find that answer here.


I want to learn wordpress from scratch. How can I learn? [closed]
It involved the following four steps:.
How do I stop Wordpress from writing single quotes in the HEAD tag?
  1. Setting up the URL Rewriting by adding a query_var, rewrite_tag and a permastruct,
  2. Being sure to flush the rewrite rules in a plugin's activation hook or manually,
  3. Adding a parse_query filter hook to set the query_vars's post to be the comment's post and to disable sticky posts for the query,
  4. Adding a template_include filter hook to filter the template file name to load a template specific template file for a single comment, and lastly
  5. To create the comment template file as /wp-content/themes/%your-theme%/comment.php.
Again, you can find the answer over here..

UPDATE:

Below is the full content that I had also posted on WordPress Answers:. There are numerous different ways to accomplish this, some more polished than others and practically all of them with potential for conflict with other plugins, but ignoring all that here's one way that is pretty close to what you asked for.

:). This solution will support a URL format like the following where %comment_id% is the numeric ID of your comment from the wp_comments table:.
http://example.com/comments/%comment_id%/.
First you'll need to configure your URL rewriting using the following code.

Hopefully it is reasonably self-explanitory but don't hesitate to ask:.
$wp->add_query_var('comment_id');  // Add the "behind-the-scenes" query variable that WordPress will use $wp_rewrite->add_rewrite_tag('%comment_id%', '([0-9]+)','comment_id=');  // Define a rewrite tag to match that assigns to the query var  $wp_rewrite->add_permastruct('comment-page', 'comments/%comment_id%');   // Define a URL pattern to match the rewrite tag. 

You'll also either need to call this code in a plugin activation hook to flush the rules, or if it's your site you can just save permalinks in the admin console's Settings > Permalinks settings area:.
global $wp_rewrite; $wp_rewrite->flush_rules(false); 
Next add a parse_query filter hook.

This will be called after WordPress has inspected the query.

It tests to see if your added comment_id query_var set and if so it tests to see if you are on the desired URL.

If yes then it loads the comment array using get_comment() in order to set the 'p' parameter (which should be set to a post ID) to the post that is related to the comment.

That way when WordPress runs the query that it is going to run no matter what at least it loads something you'll need in your comment.php theme template file below and you won't have to ran another query later when you need it.

This code also tells WordPress to ignore sticky posts using the oddly named caller_get_posts option:.
add_filter( 'parse_query', 'my_parse_query' ); function my_parse_query( $query ) {     global $wp;     if (isset($query->query['comment_id']) && substr($wp->request,0,9)=='comments/') {          $comment = get_comment($query->query['comment_id']);         $query->query_vars['p'] =  $comment->comment_post_ID; // Causes the comment's post to be loaded by the query. 

$query->query_vars['caller_get_posts'] = true; // Keeps sticky posts from invading into the top of our query.

} }
Still next you'll need to hook the code in /wp-includes/template-loader.php using the template_include filter.

This will be called after WordPress has both inspected the query and loaded the post for the comment.

Here you'll first check again for comment_id in the query_var and also for the URL being the one you want.

If so we replace the /index.php template page with /comment.php which is a theme template file you will need to create:.
add_filter( 'template_include', 'my_template_include' ); function my_template_include( $template ) {     global $wp,$wp_query;     if (isset($wp_query->query['comment_id']) && substr($wp->request,0,9)=='comments/') {         $template = str_replace('/index.php','/comment.php',$template);     }     return $template; } 
Lastly now you need to create your theme template file which I've chosen to call /comment.php.

Since it's your theme you'll want to make it look like you want but here is an example to get you started:.
<?php  /*  *  File: /wp-content/themes/my-theme/comment.php  */  global $wp_query,$post; $comment_id = $wp_query->query['comment_id']; $comment = get_comment($comment_id); $permalink = get_permalink($post->ID); get_header(); ?> <div id="container">     <div id="comment-<?php echo $comment_id; ?>" class="comment">         <p>Comment by: <span class="comment-author">             <a href="<?php echo $comment->comment_author_url; ?>"><?php echo $comment->comment_author; ?></a></span>             on <span class="comment-date"><?php echo date("D M jS Y", strtotime($comment->comment_date)); ?></span>           at <span class="comment-time"><?php echo date("h:ia", strtotime($comment->comment_date)); ?></span>         </p>         <p>About: <a href="<?php echo $permalink; ?>"><?php echo $post->post_title; ?></a></p>         <blockquote><?php echo $comment->comment_content; ?></blockquote>     </div> </div> <?php  get_sidebar(); get_footer(); 
Any questions? Just ask.. Hope this helps.. P.S.

All of the code I describing above can either go in your theme's functions.php file and/or in a plugin of your own.

A caveat is for the URL rewrite flushing rules that should go in a plugin activation hook if you are going to include it instead us just flushing them manually in the permalinks section of the admin console.

I didn't show how to register an activation hook do but if you want to learn more you can read about it here..

(New edited version after OP's comments). There are many ways to do this.

In theory this is the simplest, but maybe not 'most appropriate according to WordPress' way.

Take this as a starting point.

I haven't tested it, so you may encounter an error or two that should be solvable with some minor tweaks.

Let me know if you get stumped and I'll do my best.

So conceptually.... You should copy the page.php template file and rename it to 'comments_page.php' (or whatever you like).

Open this file in your code editor and find where the following appears: (or create it if it does not exist).
/*Template Name: page*/ 
and change it to .
/*Template Name: comments_page*/ 
Now open your WordPress admin area and create a new page.

Call it whatever you want but don't add any content.

In the right hand column, select the template that the page uses from the "Page Template" drop down menu.

Select 'comments_page' (or whatever you listed as the template name).

This tells WordPress to use your file to show this specific page instead of the default page template.

Save the page and note the page_id that WordPress generates.

. Now, find your theme's comments template, usually 'comments.php'.

Find the function wp_list_comments();.

We are going to add the name of a custom function that will control the display of your comments as an argument to this function.

For an example, go to the twenty-ten theme's files, open comments.php and you'll see what that looks like:.
wp_list_comments( array( 'callback' => 'twentyten_comment' ) ); 
Open the twenty-ten theme's functions.php and find.
function twentyten_comment() 
Copy that entire function and paste it into your theme's functions file.

Change the name to' my_comment()', and add that to the wp_list_comments function call like this:.
wp_list_comments( array('callback'=>'my_comment')); 
In your newly-created 'my_comment()' function in your functions.php file, add a link where you want to the separate page of comments (comments_page.php) using get_page_link() and a query var named 'commentID' and the comments ID..
<a href = "<?php echo get_page_link($page_id).'/?commentID='.comment_ID();?>">View this comment</a> 
Now to inappropriately add php logic to a template file.

Once you understand how this works, you can create a function in your functions.php file and then call it in the theme file.... On comments_page.php ,use $_GET['commentID'] to retrieve the comment's id value from the url, and pass it to get_comment($commentID) to retrieve the single comment and display it on a single page..
if(isset($_GET['commentID'])){$commentID = $_GET['commentID'];} $comment = get_comment($commentID); 
Now you have all the single comments information in the $comment variable as an object.

. You can decide how to display the comment, but to start, I recommend copying the contents of your theme's comments template to keep things consistent.

It will show exactly the same thing the post page shows, but it sounds like this page is intended more for the permalink to a single comment that you link to from somewhere else.

. Hope this helps.

Let me know if you run into a snag.. Note: this answer provides info given to me from Todd Perkins over at wordpress.stackexchange.com.
