ecshop 生成商品代码

一特效：

 

  二：生成代码界面：

 

<form name="theForm" method="post" action="">
  <table cellspacing="1" cellpadding="3" width="100%">
    <tr>
      <td class="label">{$lang.label_category}</td>

    </tr>
    <tr>

      <td><input name="goods_num" type="text" id="goods_num" value="1" /></td>

    <tr>

      <td><input name="sitename" type="text" id="sitename"></td>
    </tr>
    <tr>
      <td colspan="2" align="center"><input type="button" class="button" name="gen_code" value="{$lang.generate}" onclick="genCode()" />        </td>
      </tr>
    <tr>
      <td colspan="2" align="center"><textarea name="code" cols="80" rows="5" id="code"></textarea></td>
      </tr>
  </table>
</form>

<script language="JavaScript">
    var elements = document.forms['theForm'].elements;
    var url = '{$url}';

    function genCode()
    {
        // 检查输入
        if (isNaN(parseInt(elements['goods_num'].value)))
        {
            alert(goods_num_must_be_int);
            return;
        }
        if (elements['goods_num'].value < 1)
        {
            alert(goods_num_must_over_0);
            return;
        }
        if (isNaN(parseInt(elements['rows_num'].value)))
        {
            alert(rows_num_must_be_int);
            return;

        // 生成代码
        var code = '\<script src=\"' + url + 'goods_script.php?';
        if (elements['category'].value > 0)
        {
            code += 'cat_id=' + elements['category'].value + '&';

        code += 'sitename=' + encodeURI(elements['sitename'].value);
        code += '\"\>\</script\>';
        elements['code'].value = code;

    }
</script>

 

 三：生成的代码读取数据接口   

 

 

 if (!empty($_GET['cat_id']))
        {
            $sql .= ' AND ' . get_children(intval($_GET['cat_id']));
        }
        if (!empty($_GET['brand_id']))
        {
            $sql .= " AND brand_id = '" . intval($_GET['brand_id']) . "'";
        }
$output = $smarty->fetch($tpl, $cache_id);
$output = str_replace("\r", '', $output);
$output = str_replace("\n", '', $output);

echo "document.write('$output');";
