WordPress Plugin WP Sub Post

WP Sub Post is a wordpress plugin that allow you to make your wordpress post has a parent or child post.

Notes:

• Child post is a real post that has a parent.
• Child post only displayed on it’s parent post page or when parent page is displayed.
• Child post can not be viewed individually.
• Child post has all possibility like a normal post, such as attachment, custom fields etc.
  

Features:

• Add/edit parent post directly from your post area.
• No need to edit theme file.

Limitations:

• No setting page
• I don’t know about it’s compatibility.

Bugs:

• Not compatible with my syntax highlight plugin

Here is the code of this plugins…  Hahaha.. little bit messy

Demo:

See below:

Code Update WP Sub Post

There are some changes to the WP Sub Post:

• Fixed/Added, now child post can be viewed as a single post, with link to the Parent Post instead of displaying blank post with ‘Post not found’ title.
• Added, CSS class and id to the blockquote of the child post. It would be useful to make a link like http://example.com/parentpost.html#childpostXXX. while XXX is your child post ID.

Two functions that are changed subpost_template() and where_no_parent()

WP Sub Post

[raw]<pre>
function subpost_template($content) {
global $post;

$parentID = get_the_ID();
       $childposts = get_posts(array(
                                'post_type' => 'post',
                                'numberposts' => -1,
                                'post_status' => 'publish',
                                'post_parent' => $parentID
                                ));
      $subcontent = "";
    foreach($childposts as $childpost){
        $subcontent .= "
<blockquote class=\"sub_post\" id=\"subpost_".$childpost->ID."\">";
        $subcontent .= "
<h3>".$childpost->post_title."</h3>

";
        $subcontent .= $childpost->post_content;
        $subcontent .= '
<p class="postmetadata"><small>This sub post was added on: '.date('l, dS F, Y',strtotime($childpost->post_date)).' <a href="'.get_edit_post_link($childpost->ID).'" rel="nofollow">Edit</a></small>

';
        $subcontent .= "</blockquote>

";
    }

        if($post->post_parent !== 0) {

        $parent_info = '
<blockquote>This post is a child post of <strong>'.get_the_title($post->post_parent).'</strong>. To view the parent post, please <a href="'.get_permalink($post->post_parent).'">click here.</a></blockquote>

';
        $content = $parent_info.$content;
        }

    $content .= $subcontent;
    return $content;
}

function where_no_parent($where) {
    global $wpdb;
    if(!is_single()) {
     $where .= " AND post_parent  = 0";
    }
    else {
    $where .= " AND post_type = 'post'";
    }
    return $where;
}
</pre>

Finally you can see the demo here

Yesterday, I was failed to add a demo directly in this site because of incompatibility with smart tags (all smart tags are not working when WP Sub Post is activated).

The problem comes from my old stupid function subpost_template():D

Thanks and sorry to polvocdo , actually your revision is the answer.
Ha ha I’m forget to replace mine with your revision  :hammer: ….

This is a child post

This is an individual post (http://takien.com/536/this-is-a-child-post.php) that attached to the another post ( http://takien.com/550/wordpress-plugin-wp-sub-post.php)

image on the child post

Child post could be useful when you want to add an additional information to the main post,  news analysis, or update. Instead of editing the main post, you can now simply Add New post and mark it as child post.

Child post also has it’s own functionality, can handle attachment, displaying image. etc.

But you can’t see this post in the post editing page (wp-admin/edit.php) because of filter  in the plugin to prevent child post to be displayed individually in the main page, post listing, feed, etc.  Hahaha.. don’t worry, I will fix it soon.
