[已解决]php增加数据内容,显示为空.

if($submit=="submit")
改成
if($submit=="注册")
或者
if($submit)

$title=$_POST['title'];
$submit=$_POST['submit'];
上面是不是还要加
$text=$_POST['text'];
呢


mysql_connect("localhost","root","");
是不是要改成
$link = mysql_connect("localhost","root","");
呢

参考：
[CODE]<?php

$submit=$_POST['submit'];
if($submit)
{
$title=$_POST['title'];
$text=$_POST['text'];
if($text!="")
{
$link = mysql_connect("localhost","root","");
mysql_select_db("ccc");
mysql_query("set names 'gb2312'");
mysql_query("insert into cc (aa) values ('$title')");
mysql_close($link);
}
else
{
echo "输入内容为空";
}
}
?>
<form action="index.php" method="POST">
<input type="text" name="text" />
<input type="submit" name="submit" value="注册" />
</form>[/CODE]
