php - 在网格视图中显示子类别

Question

我对 php 很陌生，我对 OOP 了解不多，但我对 php 知之甚少，我有一个商店，我希望在单击链接时在其中显示子类别。是否有扩展或任何其他方式来做到这一点，我应该在哪里做？

Answer 1

You already have this in Magento. For enabling this, go to: Catalog > Manage Categories > Click on subcategories individually > Display Settings tab > set Is Anchor to Yes

Is Anchor allows to make your categories/sub-categories filterable in Layered navigation.

Answer 2

是数据库中的子类别。考虑到您的回答是肯定的，使链接指向类似

http://yoururl?cat=3 where 3 is the id of category.

接下来运行数据库查询以获取子类别。您可以使用

$pid = (int)$_GET['cat'];
mysql_query("SELECT * FROM subcat WHERE pid = '$pid'");
if(mysql_num_rows($query) != 0)
{
 while($f =mysql_fetch_array($query))
 echo $f['subcatname'];
}

Subcat = 子类别表

pid = subcat 中父 ID 的列

subcatname = subcat 中子类别的名称
