現在のカテゴリのみからのコメントをサイドバーに表示しようとしています。これまでのところ私はこれを持っています:
<?php
// Posts per page setting
$ppp = 8; //get_option('posts_per_page'); // either use the WordPress global Posts per page setting or set a custom one like $ppp = 10;
$custom_offset = 0; // If you are dealing with your custom pagination, then you can calculate the value of this offset using a formula
// category (can be a parent category)
$cat = get_query_var('cat');
$category_parent = $cat;
// lets fetch sub categories of this category and build an array
$categories = get_terms( 'category', array( 'child_of' => $category_parent, 'hide_empty' => false ) );
$category_list = array( $category_parent );
foreach( $categories as $term ) {
$category_list[] = (int) $term->term_id;
}
// fetch posts in all those categories
$posts = get_objects_in_term( $category_list, 'category' );
$sql = "SELECT comment_ID, comment_date, comment_content, comment_post_ID, user_id, comment_author
FROM {$wpdb->comments} WHERE
comment_post_ID in (".implode(',', $posts).") AND comment_approved = 1
ORDER by comment_date DESC LIMIT $ppp OFFSET $custom_offset";
$comments_list = $wpdb->get_results( $sql );
if ( count( $comments_list ) > 0 ) {
$date_format = get_option( 'date_format' );
foreach ( $comments_list as $comment ) {
?>
<li>
<a href="<?php echo ( get_permalink( $comment->comment_post_ID ) ); ?>#comment-<?php echo($comment->comment_ID); ?>"><?php echo get_avatar( $comment->user_id, 50 ); ?></a>
<span><strong><?php echo($comment->comment_author); ?></strong> commented on</span>
<h3><a href="<?php echo ( get_permalink( $comment->comment_post_ID ) ); ?>"><?php echo get_the_title ( $comment->comment_post_ID ); ?></a></h3>
<span><?php echo($comment->comment_date); ?></span>
<p>"<?php comment_excerpt(); ?>" <a href="<?php echo ( get_permalink( $comment->comment_post_ID ) ); ?>#comment-<?php echo($comment->comment_ID); ?>">Read More</a></p>
<div class="clearfloat"></div><!-- Very Important -->
</li>
<?php
}
} else {
echo '<p>No comments</p>';
}
?>
これは0のコメントまたはすべてのコメントをいたるところに表示するので、うまくいきません。私は私が間違ったことを理解していません...
この機能を試してください。
function get_category_comments($category_id, $limit = 5) {
global $wpdb;
$sql = "
SELECT {$wpdb->comments}.comment_ID
FROM
{$wpdb->comments},
{$wpdb->posts},
{$wpdb->term_taxonomy},
{$wpdb->term_relationships}
WHERE 1=1
AND {$wpdb->comments}.comment_post_ID = {$wpdb->posts}.ID
AND {$wpdb->term_relationships}.object_id = {$wpdb->posts}.ID
AND {$wpdb->term_relationships}.term_taxonomy_id = {$wpdb->term_taxonomy}.term_taxonomy_id
AND {$wpdb->comments}.comment_approved = '1'
AND {$wpdb->term_taxonomy}.term_id = '{$category_id}'
ORDER BY {$wpdb->comments}.comment_date DESC
LIMIT 0, {$limit}
";
$comments = array();
foreach ($wpdb->get_results($sql) as $c)
$comments[] = get_comment($c->comment_ID);
return $comments;
}
それからあなたはコメントを表示するために別の関数を持つことができます:
function display_category_comments() {
global $cat;
if (!$category_id = intval($cat))
return false;
$comments = get_category_comments($category_id);
?>
<ul>
<?php foreach ($comments as $c) : $post = get_post($i = $c->comment_post_ID); ?>
<li>
<?php echo $c->comment_author; ?> - <a href="<?php echo get_permalink($post->ID); ?>" title="Permalink to <?php echo $post->post_title; ?>"><?php echo $post->post_title; ?></a>
</li>
<?php endforeach; ?>
</ul>
<?php
}
