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>
Copy after login


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>
Copy after login


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 />?>
Copy after login


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
