在 goods.php 文件,
找到 $smarty->assign('goods', $goods);
在它上面增加下面代码:
方法一:
<span>$cat_arr</span> = get_parent_cats(<span>$goods</span>['cat_id'<span>]); </span><span>foreach</span> (<span>$cat_arr</span> <span>AS</span> <span>$val</span><span>) <br />{ </span><span>$goods</span>['topcat_id']=<span>$val</span>['cat_id'<span>]; </span><span> $goods</span>['topcat_name']=<span>$val</span>['cat_name'<span>]; }</span>
方法二:
<span>$cat_arr</span> = get_parent_cats(<span>$goods</span>['cat_id'<span>]); </span><span>$topcat_arr</span> = <span>end</span>(<span>$cat_arr</span><span>); </span><span>$goods</span>['topcat_id']=<span>$topcat_arr</span>['cat_id'<span>]; </span><span>$goods</span>['topcat_name']=<span>$topcat_arr</span>['cat_name'];
然后,在商品详情模板文件 goods.dwt 中调用如下:
顶级分类id:{$goods.topcat_id}
顶级分类名称name:{$goods.topcat_name}
$children = get_children($cat_id); 获得指定分类同级的所有分类以及该分类下的子分类
/**
* 获得分类下的商品
*
* @access public
* @param string $children
* @return array
*/
function category_get_goods($children, $brand, $min, $max, $ext, $size, $page, $sort, $order)
看看category.php 是怎么用的
首页调用指定分类下子分类方法
模板首页一般都有分楼层显示的分类商品,每个楼层右上角会有该分类下小分类排列显示的:
以往有些模板这里都是静态显示的,需要客户手动依次修改,现在模板中心告诉您怎样修改成动态调用,只需修改一个id即可。
1.打开您的文件根目录下 includes/lib_goods.php 文件,在最后一行加入一个方法:
function get_parent_id_tree($parent_id)
{
$three_c_arr = array();
$sql = 'SELECT count(*) FROM ' . $GLOBALS['ecs']->table('category') . " WHERE parent_id = '$parent_id' AND is_show = 1 ";
if ($GLOBALS['db']->getOne($sql))
{
$child_sql = 'SELECT cat_id, cat_name, parent_id, is_show ' .
'FROM ' . $GLOBALS['ecs']->table('category') .
"WHERE parent_id = '$parent_id' AND is_show = 1 ORDER BY sort_order ASC, cat_id ASC ";
$res = $GLOBALS['db']->getAll($child_sql);
foreach ($res AS $row)
{
if ($row['is_show'])
$three_c_arr[$row['cat_id']]['id'] = $row['cat_id'];
$three_c_arr[$row['cat_id']]['name'] = $row['cat_name'];
$three_c_arr[$row['cat_id']]['url'] = build_uri('category', array('cid' => $row['cat_id']), $row['cat_name']);
}
}
return $three_c_arr;
}
2. 在模板文件里调用,如首页index.dwt中 :
$this->assign('thiscid1', get_parent_id_tree(17));//调用父级分类的下级分类
?>
{$list.name}
括号里的“17”为分类id,按照您的网站商品分类修改......余下全文>>
