phpcms v9中相關(guān)閱讀的排序問(wèn)題,調(diào)用出來(lái)的內(nèi)容十分陳舊。于是嘗試添加 order="id DESC" 參數(shù)進(jìn)行排序,調(diào)用順序依然毫無(wú)變化。打開(kāi) phpcms/modules/content/classes/content_tag.class.php 內(nèi)容模型標(biāo)簽類(lèi)一看,發(fā)現(xiàn)該標(biāo)簽僅在內(nèi)容存在人為設(shè)置的相關(guān)閱讀時(shí),才依照order參數(shù)進(jìn)行排序。而當(dāng)內(nèi)容不存在人為設(shè)置的相關(guān)閱讀時(shí),則按照關(guān)鍵字進(jìn) 行查詢,但此時(shí)并沒(méi)有按照order參數(shù)進(jìn)行排序。而是不進(jìn)行排序。這也就是為什么文章調(diào)用的相關(guān)閱讀總是那么陳舊的原因了。
修正該問(wèn)題的方法:
修改 phpcms/modules/content/classes/content_tag.class.php 內(nèi)容模型標(biāo)簽類(lèi)文件,將 content_tag 類(lèi)中 relation 方法修改為:
/**
* 相關(guān)文章標(biāo)簽
* @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 實(shí)只是將 $r = $this->db->select($sql2, '*', $limit, '','','id'); 替換為了 $r = $this->db->select($sql2, '*', $limit, $order,'','id'); 讓order參數(shù)傳入查詢方法。
在模板當(dāng)中,使用如下標(biāo)簽,加上order參數(shù)即可實(shí)現(xiàn)排序了。
{pc:content action="relation" relation="$relation" id="$id" catid="$catid" num="5" keywords="$rs[keywords]" order="id DESC"}
{loop $data $r}
{/loop}
{/pc}
如果有潔癖的朋友,擔(dān)心直接修改PC會(huì)影響未來(lái)升級(jí),可以將其單獨(dú)提取出來(lái)。放到模板中當(dāng)作函數(shù)使用。代碼如下:
<?php
/**
* 內(nèi)容模型 - 相關(guān)文章標(biāo)簽(修正排序異常問(wèn)題)
* @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;

在模板中,使用如下PHP代碼獲取即可。
{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}
其實(shí)只是一個(gè)小問(wèn)題,PC在未來(lái)應(yīng)該會(huì)進(jìn)行修正的,以上方法提供給那些心急的站長(zhǎng)朋友們。
