关于PHP更新数据库

本帖最后由 UR_Not_Alone 于 2013-06-03 11:55:36 编辑 刚开始学PHP遇到一些基础问题请大家帮忙
从网上看的一个例子,做了下练习。
我填好页面内容点击提交时,页面默认打开insert.php,而不是执行insert.php中代码插入数据库是怎么回事啊。
代码如下
Html页面
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><br />
<html xmlns="http://www.w3.org/1999/xhtml"><br />
<head><br />
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><br />
<title>无标题文档</title><br />
</head><br />
<body><br />
<form action="insert.php" method="post" target="win"><br />
请输入新闻的title:<input type="text" name="title" /><br />
请选择新闻类型:<select name="c_id"><option value="1">体育</option><option value="2">娱乐</option></select><br />
<br /><br />
请输入新闻的content:<br /><br />
<textarea cols="60" rows="15" name="content"></textarea><br />
<input type="submit" value="提交" /><br />
</form><br />
</body><br />
</html>


insert.php
<?php<br />
include("connect_mysql.php");<br />
$q = "insert into new(title,content,time,news_cate_id) values('".$_POST["title"]."','".$_POST["content"]."',now(),".$_POST["c_id"].")";<br />
mysql_query($q);<br />
if(mysql_affected_rows()>0) echo "xinwentianjiachenggong!";<br />
?><br />
<hr /><br />
<a href="add_news.php" target="win">fanhuijixutianjiaxinwen</a>


connect_mysql.php
<?php<br />
function mysql_open()<br />
{<br />
$mysql_servername="localhost"; //<br />
$mysql_username="root";<br />
$mysql_password="11111";<br />
$mysql_dbname="new";<br />
<br />
$conn=mysql_connect($mysql_servername ,$mysql_username ,$mysql_password);<br />
      mysql_query("set names UTF8"); //UTF8<br />
      mysql_select_db($mysql_dbname , $conn);<br />
	  return $conn;<br />
}<br />
?>


另外,如果我想实现上传图片的功能该怎么做啊,求提供思路,如果有人有例子最好了,谢谢大家
