PHPCMS列表联动筛选功能开发的详细教程

phpcms实现联动筛选的教程目前还没有，下面CMS资源网就给大家分享一下phpcms如何实现列表页联动筛选，筛选效果截图如下：

话不多说，下面开始详细教程：
首先用下面代码替换掉phpcms/libs/functions/extention.func.php文件里面的代码：

$v){
		if($v['parentid']==$field_value){
			$array[$k]['name'] = $v['name'];
			$array[$k]['value'] = $k;
			$array[$k]['url'] = str_replace('{$'.$fieldname.'}',$k,$urlrule);
			$array[$k]['menu'] = $field_value == $k ? ''.$v['name'].'' : ''.$v['name'].'' ;
			}
			}
			return $array;
			}
function structure_filters_url($fieldname,$array=array(),$type = 1,$modelid) {
	if(empty($array)) {
		$array = $_GET;
		} else {
			$array = array_merge($_GET,$array);
			}
        //TODO
        $fields = getcache('model_field_'.$modelid,'model');
        if(is_array($fields) && !empty($fields)) {
			ksort($fields);
			foreach ($fields as $_v=>$_k) {
				if($_k['filtertype'] || $_k['rangetype']) {
					if(strpos(URLRULE,'.html') === FALSE) $urlpars .= '&'.$_v.'={$'.$_v.'}';
					else $urlpars .= '-{$'.$_v.'}';
					}
					}
					}
        //后期增加伪静态等其他url规则管理，apache伪静态支持9个参数
        if(strpos(URLRULE,'.html') === FALSE) $urlrule =APP_PATH.'index.php?m=content&c=index&a=lists&catid={$catid}'.$urlpars.'&page={$page}' ;
        else $urlrule =APP_PATH.'list-{$catid}'.$urlpars.'-{$page}.html';
        //根据get传值构造URL
        if (is_array($array)) foreach ($array as $_k=>$_v) {
			if($_k=='page') $_v=1;
			if($type == 1) if($_k==$fieldname) continue;
			$_findme[] = '/{\$'.$_k.'}/';
			$_replaceme[] = $_v;
			}
     //type 模式的时候，构造排除该字段名称的正则
        if($type==1) $filter = '(?!'.$fieldname.'.)';
        $_findme[] = '/{\$'.$filter.'([a-z0-9_]+)}/';
        $_replaceme[] = '';
        $urlrule = preg_replace($_findme,$_replaceme,$urlrule);
        return         $urlrule;
		}

如果大家不想复制代码，也可以直接下载下面的文件覆盖即可，下载地址如下：

 
说明一下，这里用的是模型里的下拉框，模板里面的调用代码如下：

性别：
 {php $xingbie_rang = array('男|1','女|2','组合|3')}
{loop filters('xingbie',$xingbie_rang) $r}
{$r[menu]}
{/loop}

{php $sql = structure_filters_sql($modelid)}
{php $urlrule = makeurlrule()}
 {pc:content action="lists" catid="$catid" where="$sql" num="35" order="id DESC"page="$page" moreinfo="1" urlrule="$urlrule"}
{loop $data $r}




{/loop}
{/pc}

上面的代码是以性别为例的，大家可以自己修改。
如果要实现伪静态，可以参考下面的伪静态规则：
