PHP，如何遍历表单并写入数据库？
有个样式为：
要把四个id里面的值写入到一张数据表中，请问该怎么写PHP？
回复讨论(解决方案)
不可能！你违规了
你只能得到最后一个 $_POST['id']
<?php if($_POST['submit']){ foreach ($_POST['id'] as $key => $value) { //循环插入数据库 } }?><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>无标题</title></head><body><form action="" method = "post"> <ul> <li><input type='text' name='id[]'></li> <li><input type='text' name='id[]'></li> <li><input type='text' name='id[]'></li> <li><input type='text' name='id[]'></li> </ul> <input type="submit" name="submit" value="submit" /></form></body></html>foreach循环体内又是如何操作呢？你的意思我明白了，就是写法上面有点不太懂

foreach循环体内又是如何操作呢？你的意思我明白了，就是写法上面有点不太懂
foreach ($_POST['id'] as $key => $value) { mysql_query("INSERT INTO 表名(xxx) VALUES ($value)"); }现在我喜欢$("form").serialize()直接带走所有的表单元素...

就算能直接带过去，但是后台还是要对应传值，不然插不去数据库。

foreach ($_POST['id'] as $key => $value) { mysql_query("INSERT INTO 表名(xxx) VALUES ($value)"); }谢谢你，我试了下，可以传入单维数组，现在我碰到的是个二维数组，也就是一个列表有两个name值需要传进去，唉，比如我需要传一个ID和一个TITLE进去，
可以修改$_POST['id']['title'] as .....
这样可以吗？大侠，你是否有这方面的资料，可否分享一下呢？
