好了,我现在有两张表categories
和subcategories
这样的
Categories:
id
title
description
Sub Categories:
id
catid
title
description
现在,子类别的“catid
”将具有“id
”类别的值,我想将我的类别和子类别分组并显示,如
Category
subcat
subcat
categories
subcat
subcat
答案 0 :(得分:1)
$catquery = "select * from categories";
$res = mysql_query($catquery)
while (list($id, $title, $description) = mysql_fetch_row($res)){
$subquery = "select id, title, description from subcategories where catid = {$id}";
$res = mysql_query($subquery);
echo("Category: {title} ({description})<br />");
while (list($sid, $stitle, $sdescription) = mysql_fetch_row($res)){
echo (" Subcategory: {stitle} {sdescription}<br />");
}
}
这应该显示您的类别和子类别:
类别:Category1(这是 category1)
子类别:SubCategory1 这是子类别1子类别: SubCategory2这是子类别2 类别:Category2(这是 category2)
子类别:子类别3 这是子类别3
等等
