ecshop二次开发--左侧导航

1.进入ecshop->uoload->theme->default->library->category_tree.lbi将里边的代码清空，并且将以下代码复制到进去

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<div class="box">

<input type="button" id="button1" value="商品分类" style="width:60px;font-size:12px" />

<input type="button" id="button2" value="品牌分类" style="width:60px;font-size:12px"/>

<input type="button" id="button3" value="供货商" style="width:50px;font-size:12px"/>

<div class="box_1" id="ce1">

 

<div id="category_tree">

<!--{foreach from=$categories item=cat}-->

<dl>

<dt><a href="{$cat.url}">{$cat.name|escape:html}</a></dt>

<!--{foreach from=$cat.cat_id item=child}-->

<dd><a href="{$child.url}">{$child.name|escape:html}</a></dd>

<!--{foreach from=$child.cat_id item=childer}-->

<dd>  <a href="{$childer.url}">{$childer.name|escape:html}</a></dd>

<!--{/foreach}-->

<!--{/foreach}-->

</dl>

<!--{/foreach}-->

</div>

</div>

<div class="box_1" id="ce2" style="display:none">

<div id="category_tree">

<!--{foreach from=$前边所传过来的数据(sql) item=起个名称(aa)}-->

<dl>

<dd><a href="#">{$起个名称(aa).数据库名称(brand_name)}</a></dd>

</dl>

<!--{/foreach}-->

</div>

</div>

 

<div class="box_1" id="ce3" style="display:none">

<div id="category_tree">

<!--{foreach from=$categories item=cat}-->

<dl>

<dd><a href="#">供货商测试</a></dd>

</dl>

<!--{/foreach}-->

</div>

</div>


<div class="blank5"></div>

<script>

  var button1=document.getElementById('button1');

  var button2=document.getElementById('button2');

  var button3=document.getElementById('button3');

  var ce1=document.getElementById('ce1');

  var ce2=document.getElementById('ce2');

  var ce3=document.getElementById('ce3');

  button1.onclick=function(){

      ce2.style="display:none";

      ce3.style="display:none";

      ce1.style="display:block";

  }

   button2.onclick=function(){

      ce2.style="display:block";

      ce3.style="display:none";

      ce1.style="display:none";

  }

  button3.onclick=function(){

      ce2.style="display:none";

      ce3.style="display:block";

      ce1.style="display:none";

  }

</script>

2.然后在index.php中进行sql查询并且将值传到后边

在index.php中搜索到这些代码if (!$smarty->is_cached('index.dwt', $cache_id))在这里边进行sql查询

   $sql="select * from ecs_brand";
    $add = $db->getAll($sql);
    $sqls="select * from".$ecs->table("suppliers");
    $adds = $db->getAll($sqls);
    $smarty->assign('sqls', $adds);
    $smarty->assign('sql', $add);
    assign_template();
