复制代码 代码如下:
//第一步：链接数据库
$conn=@mysql_connect("localhost:3306","root","root")or die ("mysql链接失败");
//第二步: 选择指定的数据库，设置字符集
@mysql_select_db("php_blog",$conn) or die ("db链接失败".mysql_error());
mysql_query('SET NAMES UTF8')or die ("字符集设置错误");
?>
2.增加 add.php
复制代码 代码如下:
include("conn.php");//引入链接数据库
if(!empty($_POST['sub'])){
$title=$_POST['title'];
$con=$_POST['con'];
echo $sql="insert into news(id,title,dates,contents) value (null,'$title',now(),'$con')" ;
mysql_query($sql);
echo"插入成功";
}
?>
3.删除del.php
复制代码 代码如下:
include("conn.php");//引入链接数据库
include("conn.php");//引入链接数据库
if(!empty ($_GET['id'])){
$sql="select * from news where id='".$_GET['id']."'";
$query=mysql_query($sql);
$rs=mysql_fetch_array($query);
}
if(!empty($_POST['sub'])){
$title=$_POST['title'];
$con=$_POST['con'];
$hid=$_POST['hid'];
$sql="update news set title='$title',contents='$con' where id='$hid' limit 1 ";
mysql_query($sql);
echo "";
echo"更新成功";
}
?>
if(!empty($_GET['del'])){ $d=$_GET['del']; $sql="delete from news where id ='$d'"; } $query=mysql_query($sql); echo "删除成功"; ?>
4，改 edit.php页面
include("conn.php");//引入链接数据库
if(!empty ($_GET['id'])){
$sql="select * from news where id='".$_GET['id']."'";
$query=mysql_query($sql);
$rs=mysql_fetch_array($query);
}
if(!empty($_POST['sub'])){
$title=$_POST['title'];
$con=$_POST['con'];
$hid=$_POST['hid'];
$sql="update news set title='$title',contents='$con' where id='$hid' limit 1 ";
mysql_query($sql);
echo "";
echo"更新成功";
}
?>
5.查，列表页面
添加内容
include("conn.php");//引入链接数据库
if(!empty($_GET['keys'])){
$w=" title like '%".$_GET['keys']."%'";
}else{
$w=1;
}
$sql="select * from news where $w order by id desc";
$query=mysql_query($sql);
while($rs=mysql_fetch_array($query)){
?>
标题:"> ">编辑｜｜">删除
}
?>
