PHP页面写不进数据库有关问题 !蛋疼了两天了!
PHP页面写不进数据库问题 !!!蛋疼了两天了!!
churu.php
PHP页面代码如下:
$conn=mysql_connect("localhost","root","5125241") or die("数据库链接错误");
mysql_select_db("test",$conn)or die("数据库不存在");
mysql_query("insert into news set title='这是第一个标题'");
?>
在myadmin中可以写入数据库数据 !!但是在php页面中就是什么都写不进去 !实行是php页面并没有显示什么错误!但是数据库里就是没有数据~!!!希望大侠们指正!
在网上看了 好多多 但是什么改都不见效果!头痛啊、、、、、、、、、、、、
现在我的wamp是半黄半白 再问一点 端口被占用了 是不是写不进数据库啊?? 但是 我把我端口号3306改成3333了 结果
wamp全白了 但是就是插不进数据库数据!!!
------解决方案--------------------
$conn=mysql_connect("localhost:3333","root","5125241") or die("数据库链接错误");
mysql_select_db("test",$conn)or die("数据库不存在");
mysql_query("insert into news set title='这是第一个标题'") or die(mysql_error());
不知道你说的 我的wamp是半黄半白 是什么情况?
3306端口被哪个程序占用了?
------解决方案--------------------
root用户的密码错误,拒绝访问。
------解决方案--------------------
windows我不太清楚,你可以停止wamp服务器,然后再看看这个进程是否还存在。
如果存在,就是它在排挤wamp自带的mysql
------解决方案--------------------
Field 'content' doesn't have a default value
字段 'content' 没有默认值
你给它设个默认值,或者去掉not null 属性.
------解决方案--------------------
这说明能连接到数据库中去了,但SQL语句出现了问题:
在 news 表中有一个字段被你设为 NOT NULL(值不能为空),你必须给它一个缺省值,或者每次插入都设定一个值。看样子 content字段是存储新闻正文的,一个新闻不能只有标题
insert into news ('title', 'content') VALUES ('这是标题', '这是正文')
------解决方案--------------------
现在不是php插入有问题,而是你数据库设计得不合理无法插入数据..
将你的表结构贴出来看看
------解决方案--------------------
------解决方案--------------------
应是数据库的问题
