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();}

}

最终效果如下 图:
