ECSHOP分类页面筛选功能（按分类下子分类和品牌筛选）

其实分类页面里面本来就有相关的品牌、属性、分类的筛选功能在category.php和模板加上相应的功能即可

1、读出当前分类的所有下级分类

 

   $chlidren_category = $GLOBALS['db']->getALl('SELECT cat_id,cat_name FROM ' . $GLOBALS['ecs']->table('category') ." WHERE parent_id = '$cat_id' and is_show=1");

   $category_id_all = array('all'=>array('cat_id'  => $cat_id,

                        'cat_name'    => 'all category',

                        'show'      =>1

                        )

                    );

    foreach($chlidren_category as $key=>$value)

    {

                    if($value['cat_id']==$cat_id)

                    {

                            $chlidren_category[$key]['show']=1;$category_id_all['show']=0;continue;

                            }

                            else $chlidren_category[$key]['show']=0;

            }

    $category_list = array_merge($category_id_all, $chlidren_category);

                $smarty->assign('category_list_all',    $category_list);

 

2、修改goods_list.lbi文件,  <form method="GET" name="listform">下面加入循环出分类的模板代码

     

   <!--{foreach from=$category_list_all item=cat_list}-->

         <a href="javascript:;" onClick="javascript:category_change({$cat_list.cat_id})">{$cat_list.cat_name}</a

         <!--{/foreach}-->

 

<input type="hidden" name="category" value="{$category}" />改为
<input type="hidden" id="category_id" name="category" value="{$category}" /> 

3、common.js中加入js脚本

function category_change(cat_id)

{

    document.getElementById('category_id').value = cat_id;

    setTimeout(doSubmit, 0);

    function doSubmit() {document.forms['listform'].submit();}

}
