案例或者设计师栏目需要用到筛选功能,需要对织梦进行二次开发
筛选功能首先需要在后台开启 php 功能
后台-系统-系统基本参数-其它选项-模板引擎禁用标签:php
涉及文件:
extend.func.php arc.listview.class.php
一、程序修改
一、extend.func.php 将下面代码添加到末尾
function wwwcms_filter($str,$stype="inject") { if ($stype=="inject") { $str = str_replace( array( "select", "insert", "update", "delete", "alter", "cas", "union", "into", "load_file", "outfile", "create", "join", "where", "like", "drop", "modify", "rename", "'", "/*", "*", "../", "./"), array("","","","","","","","","","","","","","","","","","","","","",""), $str); } else if ($stype=="xss") { $farr = array("/\s+/" , "/<(\/?)(script|META|STYLE|HTML|HEAD|BODY|STYLE |i?frame|b|strong|style|html|img|P|o:p|iframe|u|em|strike|BR|div|a|TABLE|TBODY|object|tr|td|st1:chsdate|FONT|span|MARQUEE|body|title|\r\n|link|meta|\?|\%)([^>]*?)>/isU", "/(<[^>]*)on[a-zA-Z]+\s*=([^>]*>)/isU", ); $tarr = array(" ", "", "\\1\\2", ); $str = preg_replace($farr, $tarr, $str); $str = str_replace( array( "<", ">", "'", "\"", ";", "/*", "*", "../", "./"), array("<",">","","","","","","",""), $str); } return $str; } /** * 载入自定义表单(用于发布) * AddFilter 复制本段并更改 AddFilter 为 AddFilter1/2/3/4/...n 可以设置 n 样式 前台调用只需更改名称即可 * @access public * @param string $fieldset 字段列表 * @param string $loadtype 载入类型 * @return string */ function AddFilter($channelid, $type=1, $fieldsnamef, $defaulttid, $loadtype='autofield') { global $tid,$dsql,$id; $tid = $defaulttid ? $defaulttid : $tid; if ($id!="") { $tidsq = $dsql->GetOne(" Select typeid From `dede_archives` where id='$id' "); $tid = $tidsq["typeid"]; } $nofilter = (isset($_REQUEST['TotalResult']) ? "&TotalResult=".$_REQUEST['TotalResult'] : '').(isset($_REQUEST['PageNo']) ? "&PageNo=".$_REQUEST['PageNo'] : ''); $filterarr = wwwcms_filter(stripos($_SERVER['REQUEST_URI'], "list.php?tid=") ? str_replace($nofilter, '', $_SERVER['REQUEST_URI']) : $GLOBALS['cfg_cmsurl']."/plus/list.php?tid=".$tid); $cInfos = $dsql->GetOne(" Select * From `dede_channeltype` where id='$channelid' "); $fieldset=$cInfos['fieldset']; $dtp = new DedeTagParse(); $dtp->SetNameSpace('field','<','>'); $dtp->LoadSource($fieldset); $dede_addonfields = ''; if(is_array($dtp->CTags)) { foreach($dtp->CTags as $tid=>$ctag) { $fieldsname = $fieldsnamef ? explode(",", $fieldsnamef) : explode(",", $ctag->GetName()); if(($loadtype!='autofield' || ($loadtype=='autofield' && $ctag->GetAtt('autofield')==1)) && in_array($ctag->GetName(), $fieldsname) ) { $href1 = explode($ctag->GetName().'=', $filterarr); $href2 = explode('&', $href1[1]); $fields_value = $href2[0]; $dede_addonfields .= '<div class="scv-shaixuan"><b>'.$ctag->GetAtt('itemname').':</b>'; switch ($type) { case 1: $dede_addonfields .= (preg_match("/&".$ctag->GetName()."=/is",$filterarr,$regm) ? '<a title="全部" href="'.str_replace("&".$ctag->GetName()."=".$fields_value,"",$filterarr).'">全部</a>' : '<span>全部</span>').' '; $addonfields_items = explode(",",$ctag->GetAtt('default')); for ($i=0; $i<count($addonfields_items); $i++) { $href = stripos($filterarr,$ctag->GetName().'=') ? str_replace("=".$fields_value,"=".urlencode($addonfields_items[$i]),$filterarr) : $filterarr.'&'.$ctag->GetName().'='.urlencode($addonfields_items[$i]);//echo $href; $dede_addonfields .= ($fields_value!=urlencode($addonfields_items[$i]) ? '<a title="'.$addonfields_items[$i].'" href="'.$href.'">'.$addonfields_items[$i].'</a>' : '<span>'.$addonfields_items[$i].'</span>')." "; } $dede_addonfields .= '</div>'; break; case 2: $dede_addonfields .= '<select name="filter"'.$ctag->GetName().' onchange="window.location=this.options[this.selectedIndex].value"> '.'<option value="'.str_replace("&".$ctag->GetName()."=".$fields_value,"",$filterarr).'">全部</option>'; $addonfields_items = explode(",",$ctag->GetAtt('default')); for ($i=0; $i<count($addonfields_items); $i++) { $href = stripos($filterarr,$ctag->GetName().'=') ? str_replace("=".$fields_value,"=".urlencode($addonfields_items[$i]),$filterarr) : $filterarr.'&'.$ctag->GetName().'='.urlencode($addonfields_items[$i]); $dede_addonfields .= '<option value="'.$href.'"'.($fields_value==urlencode($addonfields_items[$i]) ? ' selected="selected"' : '').'>'.$addonfields_items[$i].'</option> '; } $dede_addonfields .= '</select><br/> '; break; } } } } echo $dede_addonfields; }
二、arc.listview.class.php 修改处较多,建议手动添加
第一处添加 搜索
if(empty($cfg_need_typeid2)) $cfg_need_typeid2 = 'N';
在下面添加以下代码
//获得附加表的相关信息!!此段为添加内容!!! 联动筛选功能 1 $addtable = $this->ChannelUnit->ChannelInfos['addtable']; if($addtable!="") { $addJoin = " LEFT JOIN `$addtable` ON arc.id = ".$addtable.'.aid '; $addField = ''; $fields = explode(',',$this->ChannelUnit->ChannelInfos['listfields']); foreach($fields as $k=>$v) { $nfields[$v] = $k; } if(is_array($this->ChannelUnit->ChannelFields) && !empty($this->ChannelUnit->ChannelFields)) { foreach($this->ChannelUnit->ChannelFields as $k=>$arr) { if(isset($nfields[$k])) { if(!empty($arr['rename'])) { $addField .= ','.$addtable.'.'.$k.' as '.$arr['rename']; } else { $addField .= ','.$addtable.'.'.$k; } } } } if (isset($_REQUEST['tid'])) { foreach($_GET as $key => $value) { $filtersql .= ($key!="tid" && $key!="TotalResult" && $key!="PageNo") ? " AND $addtable.".wwwcms_filter($key)." = '".wwwcms_filter(urldecode($value))."'" : ''; } } } else { $addField = ''; $addJoin = ''; } //添加内容结束!!! 联动筛选功能 1
第二处添加 搜索 if(preg_match(‘/hot|click|lastpost/’, $orderby)) 在
} else { $addField = ''; $addJoin = ''; } //如果不用默认的 sortrank 或 id 排序,使用联合查询(数据量大时非常缓慢) if(preg_match('/hot|click|lastpost/', $orderby))
上面(注意:是上面)添加下面的代码
//此段为添加内容 联动筛选功能 2 if (isset($_REQUEST['tid'])) { foreach($_GET as $key => $value) { $filtersql .= ($key!="tid" && $key!="TotalResult" && $key!="PageNo") ? " AND $addtable.".wwwcms_filter($key)." = '".wwwcms_filter(urldecode($value))."'" : ''; } } //添加内容结束 联动筛选功能 2
第三处添加 搜索
$hidenform .= "<input type='hidden' name='TotalResult' value='".$this->TotalResult."'>\r\n";
在下面添加
//获取筛选参数 此段为添加内容 联动筛选功能 3 foreach($_GET as $key => $value) { $pageaddurl .= ($key!="tid" && $key!="TotalResult" && $key!="PageNo") ? "&".wwwcms_filter($key)."=".wwwcms_filter($value) : ''; } //添加内容结束 联动筛选功能 3
添加三处完成,还有四处修改
第一处修改 搜索
if($this->TotalResult==-1) 将$cquery =
后面的修改为
"SELECT COUNT(*) AS dd FROM `#@__arctiny` arc $addJoin WHERE ".$this->addSql.$filtersql;//修改 1! 联动筛选功能
第二处修改 搜索
//如果不用默认的 sortrank 或 id 排序,使用联合查询(数据量大时非常缓慢)
将 if(preg_match(‘/hot|click|lastpost/’, $orderby)) {}括号里面的内容修改为
$query = "SELECT arc.*,tp.typedir,tp.typename,tp.isdefault,tp.defaultname, tp.namerule,tp.namerule2,tp.ispart,tp.moresite,tp.siteurl,tp.sitepath $addField FROM `#@__archives` arc LEFT JOIN `#@__arctype` tp ON arc.typeid=tp.id $addJoin WHERE {$this->addSql} $filtersql $ordersql LIMIT $limitstart,$row";//修改 2 联动筛选功能
第三处修改 搜索
//普通情况先从 arctiny 表查出 ID,然后按 ID 查询(速度非常快)
(接着第二处下面)将$cquery = 后面的修改为
"SELECT id FROM `#@__arctiny` arc $addJoin WHERE {$this->addSql} $filtersql $ordersql LIMIT $limitstart,$row ";//修改 3 联动筛选功能
第四处 搜索
if($this->PageNo!=$totalpage && $totalpage>1)
搜索内容有两个结果,此处修改处为获取动态的分页列表下面,将下面{}内容修改为如下代码
{ //修改 4 联动筛选功能 $nextpage.="<a href='".$purl."PageNo=$nextpagenum".$pageaddurl."'class=\"a1\">下一页</a>\r\n"; $endpage="<a href='".$purl."PageNo=$totalpage".$pageaddurl."'class=\"a1\">末页</a>\r\n"; //修改 4 联动筛选功能 }
至此程序文件修改完成,一共三处添加,四处修改,前台调用代码如下
二、后台添加
如图所示:所有参与筛选的字段都必须使用 select 下拉框
三、前台调用
{dede:php}AddFilter(4,1,'需要调用的字段 1,需要调用的字段 2');{/dede:php} //样式 1 {dede:php}AddFilter1(4,1,'需要调用的字段 1,需要调用的字段 2');{/dede:php} //样式 2
