关于PHP更新数据库解决办法
关于PHP更新数据库
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
------解决方案--------------------
include("connect_mysql.php");
mysql_open();
------解决方案--------------------
php环境配好了没有，文件有没有放入web服务器根目录下，怎么访问的？
------解决方案--------------------
，问题出现在链接数据库上，链接数据库函数有问题,注释掉下面的函数部分就可以直接执行了！
//function mysql_open()
//{
$mysql_servername="localhost"; //
$mysql_username="root";
$mysql_password="11111";
$mysql_dbname="new";
$conn=mysql_connect($mysql_servername ,$mysql_username ,$mysql_password);
mysql_query("set names UTF8"); //UTF8
mysql_select_db($mysql_dbname , $conn);
// return $conn;
//}
------解决方案--------------------
如果 id 是主键，那么因为主键不能重复，你向其赋 max(id) 显然是不对的！应为 max(id) + 1
