不是第一次写表单提交了,但还是遇到了无法解决的问题。研究了将近一天,问了N多网友,最终解决了问题,过程颇为曲折。感谢大家的帮助。在此记录一下,以后不能在同一个地方摔倒了!

 数据库为bbs,表为test.三个字段,分别为id,name,sex。id为auto_increment。

连接数据库的php文件conn.php内容为

 $conn = @ mysql_connect("localhost", "root", "") or die("数据库链接错误");

mysql_select_db("bbs", $conn);

mysql_query("set names 'GBK'"); //使用GBK中文编码;

表单页:add2.php。内容为:

 include("conn.php");
if($_POST['submit']){
$sql="insert into test (id,name,sex) values ('','$_POST[name]','$_POST[sex]')";
mysql_query($sql); echo "成功!";
}

?>

 

     

之前的错误在哪?$_POST['submit']    $_POST[name]  记得要大写啊~~~

语法就是这样的吗?奇怪啊。还是先记住吧。以后会明白的。

需要注意的:1.$_POST[]一定要大写。无论在哪。

      2.提交的按钮一定要写上name和value.name="submit" value = “ ”

      3.action要提交到php文件

      4.解决页面中文乱码问题:在head里写删除,加上
