DedeCMS系统datalist标签调用arcurl方法(2)

//获取单篇文档信息

function GetOneArchive($aid)

{

global $dsql;

include_once(DEDEINC."/channelunit.func.php");

$aid = trim(ereg_replace('[^0-9]','',$aid));

$reArr = array();

$chRow = $dsql->GetOne("Select arc.*,ch.maintable,ch.addtable,ch.issystem

From `dede_arctiny` arc

left join `dede_channeltype` ch on ch.id=arc.channel where arc.id='$aid' ");

if(!is_array($chRow)) {

return $reArr;

}

else {

if(empty($chRow['maintable'])) $chRow['maintable'] = 'dede_archives';

}

if($chRow['issystem']!=-1)

{

$nquery = " Select arc.*,tp.typedir,tp.topid,tp.namerule,tp.moresite,tp.siteurl,tp.sitepath

From `{$chRow['maintable']}` arc left join `dede_arctype` tp on tp.id=arc.typeid

where arc.id='$aid' ";

}

else

{

$nquery = " Select arc.*,1 as ismake,0 as money,'' as filename,tp.typedir,tp.topid,tp.namerule,

tp.moresite,tp.siteurl,tp.sitepath

From `{$chRow['addtable']}` arc left join `dede_arctype` tp on tp.id=arc.typeid

where arc.aid='$aid' ";

}

$arcRow = $dsql->GetOne($nquery);

if(!is_array($arcRow)) {

return $reArr;

}

if(!isset($arcRow['description'])) {

$arcRow['description'] = '';

}

if(empty($arcRow['description']) && isset($arcRow['body'])) {

$arcRow['description'] = cn_substr(html2text($arcRow['body']),250);

}

if(!isset($arcRow['pubdate'])) {

$arcRow['pubdate'] = $arcRow['senddate'];

}

if(!isset($arcRow['notpost'])) {

$arcRow['notpost'] = 0;

}

$reArr = $arcRow;

$reArr['aid'] = $aid;

$reArr['topid'] = $arcRow['topid'];

$reArr['arctitle'] = $arcRow['title'];

$reArr['arcurl'] = GetFileUrl($aid,$arcRow['typeid'],$arcRow['senddate'],

$reArr['title'],$arcRow['ismake'],$arcRow['arcrank'],

$arcRow['namerule'], $arcRow['typedir'],$arcRow['money'],

$arcRow['filename'],$arcRow['moresite'],

$arcRow['siteurl'],$arcRow['sitepath']);

return $reArr;

}

这里，它处理$aid返回了一个$reArr数组，此数组有arcurl这个元素，这下很好理解sql标签中调用arcurl的方法了。
找到GetOneArchive函数，打开include文件夹下extend.func.php，加入以下代码：

function getOneArchiveElement($aid,$element='arcurl'){

$arcRow=GetOneArchive($aid);

return $arcRow[$element];

}

在模板文件datalist标记里调用如下标签：

{dede:field.aid function="GetOneArchiveElement(@me,'arcurl')"}

标签: datalist arcurl
