phpcms排序不变怎么办?
phpcms关联文章排序不变问题的修改方法:
打开 phpcms/modules/content/classes/content_tag.class.php 内容模型标签类,发现该标签仅在内容存在人为设置的相关阅读时,则依照order参数进行排序。而当内容不存在人为设置的相关阅读时,则按照关键字进行查询,但此时并没有按照order参数进行排序。而是不进行排序。这也就是为什么文章调用的相关阅读总是那么陈旧的原因了。
修正该问题的方法如下:修改 phpcms/modules/content/classes/content_tag.class.php 内容模型标签类文件,将 content_tag 类中 relation 方法修改为:
代码如下:/*** 相关文章标签* @param $data*/public function relation($data) {$catid = intval($data['catid']);if(!$this->set_modelid($catid)) return false;$order = $data['order'];$sql = "`status`=99";$limit = $data['id'] ? $data['limit']+1 : $data['limit'];if($data['relation']) {$relations = explode('|',trim($data['relation'],'|'));$relations = array_diff($relations, array(null));$relations = implode(',',$relations);$sql = " `id` IN ($relations)";$key_array = $this->db->select($sql, '*', $limit, $order,'','id');} elseif($data['keywords']) {$keywords = str_replace('%', '',$data['keywords']);$keywords_arr = explode(' ',$keywords);$key_array = array();$number = 0;$i =1;foreach ($keywords_arr as $_k) {$sql2 = $sql." AND `keywords` LIKE '%$_k%'".(isset($data['id']) && intval($data['id']) ? " AND `id` != '".abs(intval($data['id']))."'" : '');$r = $this->db->select($sql2, '*', $limit, $order,'','id');$number += count($r);foreach ($r as $id=>$v) {if($i<= $data['limit'] && !in_array($id, $key_array)) $key_array[$id] = $v;$i++;}if($data['limit']<$number) break;}}if($data['id']) unset($key_array[$data['id']]);return $key_array;}其实只是将 $r = $this->db->select($sql2, '*', $limit, '','','id'); 替换为了 $r = $this->db->select($sql2, '*', $limit, $order,'','id'); 让order参数传入查询方法。在模板当中,使用如下标签,加上order参数即可实现排序了。
代码如下:{pc:content action="relation" relation="$relation" id="$id" catid="$catid" num="5" keywords="$rs[keywords]" order="id DESC"}{loop $data $r}{/loop}{/pc}如果有洁癖的朋友,担心直接修改PC会影响未来升级,可以将其单独提取出来。放到模板中当作函数使用。代码如下:
代码如下:<?php/*** 内容模型 - 相关文章标签(修正排序异常问题)* @param $data*/function mk1_content_tag_relation($data) {$db = pc_base::load_model('content_model');$catid = intval($data['catid']);$siteids = getcache('category_content','commons');if(!$siteids[$catid]) return false;$siteid = $siteids[$catid];$category = getcache('category_content_'.$siteid,'commons');if(empty($category)) return false;if($category[$catid]['type']!=0) return false;$db->set_model($category[$catid]['modelid']);$order = $data['order'];$sql = "`status`=99";$limit = $data['id'] ? $data['limit']+1 : $data['limit'];if($data['relation']) {$relations = explode('|',trim($data['relation'],'|'));$relations = array_diff($relations, array(null));$relations = implode(',',$relations);$sql = " `id` IN ($relations)";$key_array = $db->select($sql, '*', $limit, $order,'','id');} elseif($data['keywords']) {$keywords = str_replace('%', '',$data['keywords']);$keywords_arr = explode(' ',$keywords);$key_array = array();$number = 0;$i =1;foreach ($keywords_arr as $_k) {$sql2 = $sql." AND `keywords` LIKE '%$_k%'".(isset($data['id']) && intval($data['id']) ? " AND `id` != '".abs(intval($data['id']))."'" : '');$r = $db->select($sql2, '*', $limit, $order,'','id');$number += count($r);foreach ($r as $id=>$v) {if($i<= $data['limit'] && !in_array($id, $key_array)) $key_array[$id] = $v;$i++;}if($data['limit']<$number) break;}}if($data['id']) unset($key_array[$data['id']]);return $key_array;}?>在模板中,使用如下PHP代码获取即可。
代码如下:{php $data = mk1_content_tag_relation(array('relation'=>$relation,'id'=>$id,'catid'=>$catid,'keywords'=>$rs['keywords'],'order'=>'id DESC','limit'=>'4')); }{loop $data $r}{/loop}其实只是一个小问题,PC在未来应该会进行修正的,以上方法提供给那些心急的站长朋友们。
