高分求php高手写一处理下面表单的代码
表单问题，单选的多个选项应该用同一个name
你原来的
tr

ked/
门店自取
label
input type="radio"name="shangmensongche"value="radiobutton"/
上门送车/label/td

用php处理表单数据
LZ应该是这样$_POST['hobby'][0] , 至于里面的''写与不写都可以，最好要写上。数字的话不写也可以。
PHP表单简单代码处理
?php
if(isset($_POST["btn_submit"])){
if(empty($_POST['username'])){
echo "你没有输入用户名 ";
exit(0);
}
if (empty($_POST['password'])){
echo "你没有输入密码：";
exit(0);
}
echo"你的 ".$_POST['user_name']."
";
echo"你的".$_POST['password']."
";
echo"你的 ".$_POST['age']."
";
if (!empty($_POST['languages'])){
echo "你选择的为：";
foreach ($_POST['languages'] as $lang){
echo $lang. " ";
}
echo "你的自我介绍： ".n12br($_POST['intro'])."
";
echo "网页隐藏值"： ".$_POST['from']."
";
}
?
请把代码里面的中文标点换成英文的就可以了
