织梦cms分类信息按联动类别筛选的实现方法

注意：本教程只在DedeCMS V5.6上测试过，v5.7sp1的话一般也会通用，请自行测试！

实现方法：1. 修改include aglibinfolink.lib.php，找到：require_once(DEDEROOT.'/data/enums/infotype.php');在其下面添加：require_once(DEDEROOT.'/data/enums/自定义联动类别字段名.php');function lib_infolink($ctag,$refObj){ global $dsql,$nativeplace,$infotype,$自定义联动类别字段 名,$hasSetEnumJs,$cfg_cmspath,$cfg_mainsite; global $em_nativeplaces,$em_infotypes,$em_自定义联动类别字段名s; //看清楚，这里后面的个S$fields = array('nativeplace'=>'','infotype'=>'','自定义联动类别字段名'=> '','typeid'=>$typeid, 'channelid'=>$channelid,'linkallplace'=>'','linkalltype'=> '','linkeall自定义联动类别字段名'=>'');$fields['nativeplace'] = $fields['infotype'] = $fields['自定义联动类别字段名'] = '';找到：if(is_array($ctp->CTags))在其下面添加：折叠展开PHP代码复制内容到剪贴板$fields['linkalltype'] = "<a href='{$baseurl}plus/list.php?channelid={$channelid}&tid={$typeid}& amp;nativeplace={$nativeplace}'>不限</a>";//下面添加一行$fields['linkeall自定义联动类别字段名'] = "<a href='{$baseurl}plus/list.php?channelid={$channelid}&tid={$typeid}& amp;nativeplace={$nativeplace}'>不限</a>"; //自定义联动类别字段链接 if(emptyempty($自定义联动类别字段名)) { foreach($em_自定义联动类别字段名s as $eid=>$em) { if($eid % 500 != 0) continue; $fields['自定义联动类别字段名'] .= " <a href='{$baseurl}plus/list.php?channelid={$channelid}&tid={$typeid}& amp;自定义联动类别字段名={$eid}&nativeplace={$nativeplace}'>{$em}</a& gt;"; } }
