WordPress：试图让评论显示在主页上的问题

Question

我正在尝试让 cmets 显示在主页上，但我遇到了问题。

$withcomments = 1;
comments_template();

我已将上面的 PHP 代码放在我的 index.php 文件中。出现注释框，但由于某些原因，cmets 没有出现。显然，这段代码是为了让 cmets 和评论框都出现，所以我对为什么 cmets 没有出现感到有点困惑。有人有解决办法吗？

Answer 1

你可以试试wp_list_comments()这个函数：

<ol class="commentlist">
<?php wp_list_comments(); ?>
</ol>

Answer 2

如果不在单个帖子或页面上，Wordpress 不会显示 cmets 模板。 如果您想展示，那么您必须创建满足您要求的自定义功能。

当前函数位于 wp-includes >> comment-template.php 文件第 851 行。

这里是显示cmets列表的自定义函数，放在functions.php主题文件中：

        function custom_comments_template( $file = '/comments.php', $separate_comments = false ) {
            global $wp_query, $withcomments, $post, $wpdb, $id, $comment, $user_login, $user_ID, $user_identity, $overridden_cpage;


            if ( empty($file) )
                $file = '/comments.php';

            $req = get_option('require_name_email');

            /**
             * Comment author information fetched from the comment cookies.
             *
             * @uses wp_get_current_commenter()
             */
            $commenter = wp_get_current_commenter();

            /**
             * The name of the current comment author escaped for use in attributes.
             */
            $comment_author = $commenter['comment_author']; // Escaped by sanitize_comment_cookies()

            /**
             * The email address of the current comment author escaped for use in attributes.
             */
            $comment_author_email = $commenter['comment_author_email'];  // Escaped by sanitize_comment_cookies()

            /**
             * The url of the current comment author escaped for use in attributes.
             */
            $comment_author_url = esc_url($commenter['comment_author_url']);

            /** @todo Use API instead of SELECTs. */
            if ( $user_ID) {
                $comments = $wpdb->get_results($wpdb->prepare("SELECT * FROM $wpdb->comments WHERE comment_post_ID = %d AND (comment_approved = '1' OR ( user_id = %d AND comment_approved = '0' ) )  ORDER BY comment_date_gmt", $post->ID, $user_ID));
            } else if ( empty($comment_author) ) {
                $comments = get_comments( array('post_id' => $post->ID, 'status' => 'approve', 'order' => 'ASC') );
            } else {
                $comments = $wpdb->get_results($wpdb->prepare("SELECT * FROM $wpdb->comments WHERE comment_post_ID = %d AND ( comment_approved = '1' OR ( comment_author = %s AND comment_author_email = %s AND comment_approved = '0' ) ) ORDER BY comment_date_gmt", $post->ID, wp_specialchars_decode($comment_author,ENT_QUOTES), $comment_author_email));
            }

            // keep $comments for legacy's sake
            $wp_query->comments = apply_filters( 'comments_array', $comments, $post->ID );
            $comments = &$wp_query->comments;
            $wp_query->comment_count = count($wp_query->comments);
            update_comment_cache($wp_query->comments);

            if ( $separate_comments ) {
                $wp_query->comments_by_type = &separate_comments($comments);
                $comments_by_type = &$wp_query->comments_by_type;
            }

            $overridden_cpage = false;
            if ( '' == get_query_var('cpage') && get_option('page_comments') ) {
                set_query_var( 'cpage', 'newest' == get_option('default_comments_page') ? get_comment_pages_count() : 1 );
                $overridden_cpage = true;
            }

            if ( !defined('COMMENTS_TEMPLATE') || !COMMENTS_TEMPLATE)
                define('COMMENTS_TEMPLATE', true);

            $include = apply_filters('comments_template', STYLESHEETPATH . $file );
            if ( file_exists( $include ) )
                require( $include );
            elseif ( file_exists( TEMPLATEPATH . $file ) )
                require( TEMPLATEPATH . $file );
            else // Backward compat code will be removed in a future release
                require( ABSPATH . WPINC . '/theme-compat/comments.php');
        }

现在你可以在你的模板中使用这个函数了：

       <?php custom_comments_template( '', true ); ?> 

希望这篇文章对你有所帮助。一切顺利;)
