回复讨论(解决方案)
delete tbl_name where id in($var1, $var2,...)
这就是一个$_POST数组吧,一个form中提交多个内容用$_POST[]传给PHP,
PHP获取$_POST,用foreach遍历$_POST,里面用"DELETE `DB_NAME` WHERE id = ".$_POST[]

怎么把FORM中提交过来的ID 放在一个数组中...
你生成checkbox时就可以指定为数组了啊,然后提交后就是一个数组。
然后遍历删除或者in() ...删除都可以
$_POST本身就是数组呀。
每一个标签都是一个input对吧?每一个input都有个name值,
LZ在复选之后点击提交(submit),$_POST['这里面就是input的name值']就会提交到PHP页面。
要是选中了就是true没选中就是false。
在php页面里用
if($_POST['input的name值']){
echo '我被选中了';
//这里写MYSQL删除语句
}
这个if语句外面套上一个while就好了。

其实不用while循环液可以,我是这样做的
include("../conn/conn.php"); $array = implode(",",$_POST['flags']); $query = "delete from tbl_user where ID in ($array)"; $sql = mysql_query($query); if($sql){ echo"<script>alert('删除成功');window.location.href='show_user.php'</script>"; }else{ echo "<script>alert('删除失败');window.location.href='show_user.php'</script>"; }
文本框这么写:
<input name="id[]" id="pid" value="1"/><input name="id[]" id="pid" value="2"/><input name="id[]" id="pid" value="3"/><input name="id[]" id="pid" value="4"/>当你post过去的时候,在服务端获取:$id = $_POST['id'];你勾选哪一栏,获取到就是哪一栏的值。
