Emlog非插件实现文章添加相关文章的方法

Emlog非插件实现文章添加相关文章的方法
第一步：在模板文件module.php中加入以下代码

<?php
//文章详情页下相关文章
function xg_logs($logData = array()){
if (is_file($configfile)) {require $configfile;}else{
$related_log_type = 'sort';//相关日志类型，sort为分类，tag为标签；
$related_log_sort = 'views_desc';//排列方式，views_desc 为点击数（降序）comnum_desc 为评论数（降序） rand 为随机 views_asc 为点击数（升序）comnum_asc 为评论数（升序）
$related_log_num = '10'; //显示文章数
$related_inrss = 'y'; //是否显示在rss订阅中，y为是，其它值为否
}global $value;$DB = MySql::getInstance();$CACHE = Cache::getInstance();extract($logData);if($value)
{$logid = $value['id'];$sortid = $value['sortid'];global $abstract;}
$sql = "SELECT gid,title FROM ".DB_PREFIX."blog WHERE hide='n' AND type='blog'";
if($related_log_type == 'tag'){$log_cache_tags = $CACHE->readCache('logtags');$Tag_Model = new Tag_Model();$related_log_id_str = '0';foreach($log_cache_tags[$logid] as $key => $val){$related_log_id_str .= ','.$Tag_Model->getTagByName($val['tagname']);}
$sql .= " AND gid!=$logid AND gid IN ($related_log_id_str)";}else{
$sql .= " AND gid!=$logid AND sortid=$sortid";}
switch ($related_log_sort){case 'views_desc':{
$sql .= " ORDER BY views DESC";break;}case 'views_asc':{
$sql .= " ORDER BY views ASC";break;}case 'comnum_desc':{
$sql .= " ORDER BY comnum DESC";break;}case 'comnum_asc':{
$sql .= " ORDER BY comnum ASC";break;}case 'rand':{
$sql .= " ORDER BY rand()";break;}}
$sql .= " LIMIT 0,$related_log_num";
$related_logs = array();$query = $DB->query($sql);while($row = $DB->fetch_array($query))
{$row['gid'] = intval($row['gid']);$row['title'] = htmlspecialchars($row['title']);$related_logs[] = $row;}
$out = '';if(!empty($related_logs)){foreach($related_logs as $val){
$out .= "<li><a href=\"".Url::log($val['gid'])."\" title=\"{$val['title']}\">{$val['title']}</a></li>";
}}if(!empty($value['content'])){if($related_inrss == 'y'){$abstract .= $out;}}else{echo $out;}}
?>

第二步：在模板文件echo_log.php的适合位置放入<?php xg_logs($logData);?>，最后写上css格式就ok了
