一些评论比较多的媒体站,管理员会把一些用户写的好评单独输出在侧边栏,但是怎么设置好评和输出呢?我们可以在 WordPress 后台评论管理界面评论管理区添加一个新的好评动作,并且通过 WP_Comment_Query 这个 Class 输出所有好评。
详细代码如下:
代码语言:javascript复制<?php
/*
Plugin Name: WPJAM 好评
Plugin URI: http://blog.wpjam.com/m/wpjam-good-comments/
Description: 管理员可以在后台留言列表设置某条评论为好评,在前台通过<code>wpjam_get_good_comments</code>调用所有好评的评论。
Version: 0.1

add_filter('comment_row_actions','wpjam_good_comments_comment_row_actions',10,2);
function wpjam_good_comments_comment_row_actions($actions, $comment ){
if(get_comment_meta( $comment->comment_ID, 'good_comment',true) == '1'){
$actions['good_comment'] = '<a href="'.home_url('/wp-admin/edit-comments.php?good_comment=0&comment_id='.$comment->comment_ID).'">取消好评</a>';
}else{
$actions['good_comment'] = '<a href="'.home_url('/wp-admin/edit-comments.php?good_comment=1&comment_id='.$comment->comment_ID).'">好评</a>';
}
return $actions;
}
add_action('admin_head','wpjam_good_comments_admin_head');
function wpjam_good_comments_admin_head(){
if(isset($_REQUEST['good_comment'])){
if($_REQUEST['good_comment'] == '1'){
add_comment_meta( $_REQUEST['comment_id'], 'good_comment', '1');
}elseif($_REQUEST['good_comment'] == '0'){
delete_comment_meta( $_REQUEST['comment_id'], 'good_comment');
}
}
}
function wpjam_get_good_comments(){
$comments_query = new WP_Comment_Query;
$comments = $comments_query->query( array( 'meta_key' => 'good_comment', 'meta_value' => '1', 'number' => 10 ) );
if ( $comments ) {
foreach ( $comments as $comment ) {
$post = get_post($cooment->comment_post_ID);
echo '
<li>
'.get_avatar($comment->comment_ID,50).'
<a href="'.get_permalink($comment->comment_post_ID).'" title="'. esc_attr(strip_tags($post->post_title)).'"><strong>@'.$comment->comment_author.'</strong>:'.get_comment_text($comment->comment_ID).'</a>
</li>
';
}
}
}
将上面插件单独保存为一个插件,并上传激活,然后既可以使用 wpjam_get_good_comments
模板函数输出最新的10条好评了。
