自己做wordpress评论插件修改评论样式(两步美化评论内容)

代码如下:

<?php</p> <p>/**
* 继承WP_Widget_Recent_Comments
* 这样就只需要重写widget方法就可以了
*/
class My_Widget_Recent_Comments extends WP_Widget_Recent_Comments {</p> <p> /**
* 构造方法，主要是定义小工具的名称，介绍
*/
function My_Widget_Recent_Comments() {
$widget_ops = array('classname' => 'my_widget_recent_comments', 'description' => __('显示最新评论内容'));
$this->WP_Widget('my-recent-comments', __('我的最新评论', 'my'), $widget_ops);
}</p> <p> /**
* 小工具的渲染方法，这里就是输出评论
*/
function widget($args, $instance) {
global $wpdb, $comments, $comment;</p> <p> $cache = wp_cache_get('my_widget_recent_comments', 'widget');</p> <p> if (!is_array($cache))
$cache = array();</p> <p> if (!isset($args['widget_id']))
$args['widget_id'] = $this->id;</p> <p> if (isset($cache[$args['widget_id']])) {
echo $cache[$args['widget_id']];
return;
}</p> <p> extract($args, EXTR_SKIP);
$output = '';
$title = apply_filters('widget_title', empty($instance['title']) ? __('Recent Comments') : $instance['title'], $instance, $this->id_base);
if (empty($instance['number']) || !$number = absint($instance['number']))
$number = 5;
//获取评论，过滤掉管理员自己
$comments = $wpdb->get_results("SELECT * FROM $wpdb->comments WHERE user_id !=2 and comment_approved = '1' and comment_type not in ('pingback','trackback') ORDER BY comment_date_gmt DESC LIMIT $number");
$output .= $before_widget;
if ($title)
$output .= $before_title . $title . $after_title;</p> <p> $output .= '<ul id="myrecentcomments">';
if ($comments) {
// Prime cache for associated posts. (Prime post term cache if we need it for permalinks.)
$post_ids = array_unique(wp_list_pluck($comments, 'comment_post_ID'));
_prime_post_caches($post_ids, strpos(get_option('permalink_structure'), '%category%'), false);</p> <p> foreach ((array) $comments as $comment) {
//头像
$avatar = get_avatar($comment, 40);
//作者名称
$author = get_comment_author();
//评论内容
$content = apply_filters('get_comment_text', $comment->comment_content);
$content = mb_strimwidth(strip_tags($content), 0, '65', '…', 'UTF-8');
$content = convert_smilies($content);
//评论的文章
$post = '<a href="' . esc_url(get_comment_link($comment->comment_ID)) . '">' . get_the_title($comment->comment_post_ID) . '</a>';</p> <p> //这里就是输出的html，可以根据需要自行修改
$output .= '<li class="comment" style="padding-bottom: 5px; ">
<div>
<table class="tablayout"><tbody><tr>
<td class="tdleft" style="width:55px;vertical-align:top;">' . $avatar . '</td>
<td class="tdleft" style="vertical-align:top;">
<p class="comment-author"><strong><span class="fn">' . $author . '</span></strong> <span class="says">发表在 ' . $post . '</span></p>
</tr></tbody></table>
</div>
<div class="comment-content"><p class="last">' . $content . '</p>
</div>
</li>';
}
}
$output .= '</ul>';
$output .= $after_widget;</p> <p> echo $output;
$cache[$args['widget_id']] = $output;
wp_cache_set('my_widget_recent_comments', $cache, 'widget');
}</p> <p>}</p> <p>//注册小工具
register_widget('My_Widget_Recent_Comments');

代码如下:

require(get_template_directory().'/../../widgets/comments.php');
