if( empty($arcid) || $byabs==0 ) { $orderquery = " order by arc.id desc "; } else { $orderquery = " order by ABS(arc.id - ".$arcid.") "; } likearticle標(biāo)簽?zāi)J(rèn)的排序方式。賦予標(biāo)簽orderby屬性那么這段代碼就沒意義了,先在源碼中注釋掉這段代碼 直接延用默認(rèn)的order by 子句變量$orderquery,這樣sql語句就不用做更改了。 創(chuàng)建新變量 orderquery='';//mysql 查詢語句中的order by子句 初始為空 然后根據(jù)傳遞的值做相應(yīng)的判斷,在這里只做一些最常用的值的判斷 根據(jù)$orderby的值做不同的orderby 查詢 if($orderby=='hot' || $orderby=='click') $orderquery = " order by arc.click $orderWay"; else if($orderby == 'sortrank' || $orderby=='pubdate') $orderquery = " order by arc.sortrank $orderWay"; else if($orderby == 'id') $orderquery = " order by arc.id $orderWay"; else if($orderby == 'near') $orderquery = " order by ABS(arc.id - ".$arcid.")"; else if($orderby == 'lastpost') $orderquery = " order by arc.lastpost $orderWay"; else if($orderby == 'scores') $orderquery = " order by arc.scores $orderWay"; else if($orderby == 'rand') $orderquery = " order by rand()"; else if($orderby == 'weight') $orderquery = " order by arc.weight asc";//如果沒有特定設(shè)置排序則按照權(quán)重先排序 else $orderquery = " order by arc.sortrank $orderWay"; ok這樣就為likearticle標(biāo)簽增加了完整的order by 屬性 2.subday屬性(標(biāo)簽獲取subday指定的最近幾天的數(shù)據(jù)) 同樣先獲得subday 的屬性值 $subday=$ctag->GetAtt('subday'); 然后做時間差計(jì)算 if($subday > 0) { $ntime = gmmktime(0, 0, 0, gmdate('m'), gmdate('d'), gmdate('Y')); $limitday = $ntime - ($subday * 24 * 3600); $subdaysql = " and arc.senddate > $limitday "; } 然后在標(biāo)簽源碼的兩處sql查詢語句中 增加$subdaysql子句判斷 第一處為: $query = "Select arc.*,tp.typedir,tp.typename,tp.corank,tp.isdefault,tp.defaultname,tp.namerule, tp.namerule2,tp.ispart,tp.moresite,tp.siteurl,tp.sitepath from `dede_archives` arc left join `dede_arctype` tp on arc.typeid=tp.id where arc.arcrank>-1 and ($keyword) $typeid $orderquery limit 0, $row"; 修改為: $query = "Select arc.*,tp.typedir,tp.typename,tp.corank,tp.isdefault,tp.defaultname,tp.namerule, tp.namerule2,tp.ispart,tp.moresite,tp.siteurl,tp.sitepath from `dede_archives` arc left join `dede_arctype` tp on arc.typeid=tp.id where arc.arcrank>-1 and ($keyword) $typeid $subdaysql $orderquery limit 0, $row"; 第二處為: $query = "Select arc.*,tp.typedir,tp.typename,tp.corank,tp.isdefault,tp.defaultname,tp.namerule, tp.namerule2,tp.ispart,tp.moresite,tp.siteurl,tp.sitepath from `dede_archives` arc left join `dede_arctype` tp on arc.typeid=tp.id where arc.arcrank>-1 and $typeid $orderquery limit 0, $row"; 修改為: $query = "Select arc.*,tp.typedir,tp.typename,tp.corank,tp.isdefault,tp.defaultname,tp.namerule, tp.namerule2,tp.ispart,tp.moresite,tp.siteurl,tp.sitepath from `dede_archives` arc left join `dede_arctype` tp on arc.typeid=tp.id where arc.arcrank>-1 and $typeid $subdaysql $orderquery limit 0, $row"; 做完以上更改就為likearticle標(biāo)簽增加了subday屬性 以下為修改完之后的likearticle.lib.php的完整代碼(增加了 orderby 和 subday 屬性) 修改之后完整文件: 查看源碼打印代碼幫助 <?php if(!defined('DEDEINC')) exit('Request Error!'); /** * 自動關(guān)連文檔標(biāo)簽 * * @version $Id: likearticle.lib.php 1 9:29 2010年7月6日Z tianya $ * @package DedeCMS.Taglib * @copyright Copyright (c) 2007 - 2010, DesDev, Inc. * @license http://help.dedecms.com/usersguide/license.html * @link http://www.dedecms.com */ /*>>dede>> <name>相關(guān)文檔</name> <type>全局標(biāo)記</type> <for>V55,V56,V57</for> <description>自動關(guān)連文檔標(biāo)簽</description> <demo> {dede:likearticle row='' col='' titlelen='' infolen=''} <a href='[field:arcurl/]'>[field:title/]</a> {/dede:likearticle} </demo> <attributes> <iterm>col:分多少列顯示(默認(rèn)為單列)</iterm> <iterm>row:返回文檔列表總數(shù)</iterm> <iterm>titlelen:標(biāo)題長度 等同于titlelength</iterm> <iterm>infolen:表示內(nèi)容簡介長度 等同于infolength</iterm> <iterm>mytypeid:手工指定要限定的欄目id,用,分開表示多個</iterm> <iterm>innertext:單條記錄樣式(指標(biāo)簽中間的內(nèi)容)</iterm> </attributes> >>dede>>*/ function lib_likearticle(&$ctag,&$refObj) { global $dsql; //屬性處理 $attlist="row|12,titlelen|28,infolen|150,col|1,tablewidth|100,mytypeid|0,byabs|0,imgwidth|120,imgheight|90<span >,start|0,orderby|null,inword|*,channelid|*</span>"; FillAttsDefault($ctag->CAttribute->Items,$attlist); extract($ctag->CAttribute->Items, EXTR_SKIP); $revalue = ''; if(empty($tablewidth)) $tablewidth = 100; if(empty($col)) $col = 1; $colWidth = ceil(100/$col); $tablewidth = $tablewidth."%"; $colWidth = $colWidth."%"; $ids = array(); $tids = array(); if(!empty($refObj->Fields['tags'])) { $keyword = $refObj->Fields['tags']; } else { $keyword = ( !empty($refObj->Fields['keywords']) ?
