我对如何做这件事感到有些困惑。我有一个列出数据库数据的主显示页面，然后我有一个插入表单的链接，一个编辑表单删除按钮，另一个用于评论。对于注释按钮，我需要转到一个空白表单，以便我可以将其添加为注释，以便它成为我点击的记录的子项。然后孩子应该有一个注释按钮，然后可以添加一个新的记录作为子子等。
问题是我被卡住了，所以任何帮助都会非常感激。

答案 0 :(得分：0)
也许不完美，但我会订购类似的东西：
数据建模：
|pages ([idPage], ...)| 0..n
1,1 |mainComments ([idPage, idMainComment], ...)| 0..n
1,1 |secondaryComments ([idPage, idMainComment, idSecondaryComment], ...)|
<强> PHP：
$query = mysql_query('SELECT * FROM mainComments WHERE idPage = 12');
while ($data = mysql_fetch_assoc($query)) {
//echo mainComments
//echo forms for each
$query2 = mysql_query('SELECT * FROM secondaryComments
WHERE idPage = 12
AND idMainComment = '.$data['idMainComment']);
while ($data2 = mysql_fetch_assoc($query2)) {
//echo secondaryComments
//echo forms for each
}
}
