Loading... phpcms V9内容管理系统 调用随机文章标签 `phpcms/libs/functions/extention.func.php`里面添加一个随机文章列表的函数: /* * 随机读取文章列表 * * @param $modelid 模型ID 必须 * @param $catid 栏目ID 可选,为0或未指定调去全模型的数据 * @param $siteid 站点ID 可选,默认为1 * @param $thumb 是否必须有缩微图 可选,默认为0 * @param $num 调用文章数量 可选,默认为10 * @return array 返回随机文章列表数组 */ function suiji($modelid, $catid, $siteid = 1, $thumb = 0, $num = 10) {if(!$modelid = intval($modelid))return false; $sitid = intval($siteid) ? intval($siteid) : 1; $catid = intval($catid); $num = intval($num); $thumb = intval($thumb) ? " AND thumb != ''" : ''; $CATEGORYS = getcache('category_content_'.$siteid,'commons'); if($CATEGORYS[$catid]['child']){ $catids_str = $CATEGORYS[$catid]['arrchildid']; $pos = strpos($catids_str,',')+1; $catids_str = substr($catids_str, $pos); $sql = " AND catid IN ($catids_str)".$thumb; } elseif($catid) { $sql = " AND catid='$catid'".$thumb; } else { $sql = $thumb; } $c_db = pc_base::load_model('content_model'); $c_db->set_model($modelid); $id = ''; for($i=1;$i<=$num;$i++) { $not = $id ? " AND id NOT IN ($id) " : ''; $rs = $c_db->query("SELECT * FROM $c_db->table_name AS t1 JOIN (SELECT ROUND(RAND()*(SELECT MAX(id) FROM $c_db->table_name WHERE status = 99 $sql)) AS id2) AS t2 WHERE t1.id>=t2.id2 and t1.status = 99 $sql $not ORDER BY t1.id ASC LIMIT 1"); while($r = mysql_fetch_array($rs,MYSQL_ASSOC)){ $return[]=$r; $id = $id ? $id.','.$r['id'] : $r['id']; } } return $return; } 使用举例: <div class="box"> <h5 class="title-2">随机文章</h5> <ul class="content"> {php $data = suiji(1,0,1,0,15)} {loop $data $r} <li> · <a href="{$r[url]}" target="_blank" title="{$r[title]}">{str_cut($r[title], 51, '')}</a></li> {/loop} </ul> </div> 本修改不影响以后v9升级,因为extention.func.php文件就是官方专门用了让开放者放自己的扩展函数库的。 Last modification:September 21, 2022 © Allow specification reprint Like 如果觉得我的文章对你有用,请随意赞赏
