时间Sat Aug 29 10:48:56 2009
※ 引述《idcomputer (顺)》之铭言：
: 画面是三层式下拉选单，
: 如果list想用mysql资料表里面资料的话
: 该怎麽去修改透用呢?!

↑上面这段有点不太了解~~想请问一下如果我的关联资料表
A
id、name
B
id、Aid、name
那上面这句语法该怎麽修改呢?!
$sql = "SELECT A.*, B.* FROM "
. A . " as A, "
. B . " as B where a.id = b.Aid
order by a.id";
是这样修改吗?!
if( !($result = $db->sql_query($sql)) )
{
die("Could not query config information" . $sql);
}
while($row = $db->sql_fetchrow($result)){
/* 先把中文用 trim 输出 */
$row['dep_name'] = trim($row['dep_name']);
$dep_array .= ($dep_array == '' ) ? "{'When':'".$row['college_id']."','Value':'".$row['dep_id']."','Text':'".$row['dep_name']."'}" : ", {'When':'".$row['college_id']."','Value':'".$row['dep_id']."','Text':'".$row['dep_name']."'}";
}
