自己创建数据库就好。
求用PHP写一个简单基本的留言板代码,有点急
数据库的创建
CREATE DATABASE GBOOK;
CREATE TABLE `gbook` (
`id` INT( 255 ) UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`name` VARCHAR( 10 ) NOT NULL ,
`sex` TINYINT( 1 ) UNSIGNED NOT NULL ,
`email` VARCHAR( 255 ) NOT NULL ,
`info` TEXT NOT NULL ,
`ip` VARCHAR( 15 ) NOT NULL ,
`time_at` DATETIME NOT NULL
)
主要页面有:
input.html为初始页
insert.php为把输入内容送入数据库
show.php显示留言板内容
change.php修改留言板内容的界面
del.php删除留言板内容
change_ok.php修改留言板内容并送入数据库

请问前辈们我想实现一个PHP留言板,页面不用刷新就能显示提交的内容!
前端页面中加jquery(JavaScript)代码:
function btn_click(){
var url = 'php_ajax_example.php';
var comment = '这是你的评论内容';//你自己看怎么获取它,
//例如你把评论放在textarea id="comment"/textarea中,
//var comment = $.trim($("#comment").html());
var userid = 123;//评论者的id(如果要求已登录)
var username = 'jack';//评论者名字
var email = '123@email.com';
$.post(url,
{comment:comment,id:userid,name:username,email:email},
function(back_data){
alert(back_data);
});
}
button onclick="btn_click();"提交评论/button
新建一个文件:php_ajax_example.php,代码:
?php
var comment = $_POST['comment'];
var userid = $_POST['id'];
//......补上你需要的数据
//把以上数据存入数据库
echo '评论保存成功!';
?
求教怎么用PHP做个留言板。
一个html表单,包含留言信息,提交给一个php文件,然后php把数据存入相应数据库。
查看留言则是php从数据库读出相应数据,然后显示给用户。
急求一个PHP的简单的留言板,输入临时名字 然后输入留言提交就可以显示在页面的
?php
include 'conn.php';
$action = $_GET['action'];
$user=str_replace(" ","",$_POST[textfield]);
if($_POST['Submit2']){
if(!empty($_POST[textfield])){
$user=str_replace(" ","",$_POST[textfield]);
$password=str_replace(" ","",$_POST[textfield2]);
$user1=md5($user);
$password1=md5($password);
function userlogin($user1)
{
global $manager;
$sql="select * from $manager where user='$user1';";
//$sql="insert into manager (user,password) values ('$user','$password');";//用于插入需要的管理员用户信息
$query=mysql_query($sql);
$row=mysql_fetch_array($query);
return $row;
}
$row=userlogin($user1);
if($row){
$ps=$password1==$row[password];
}else{
$ps=FALSE;
// echo "script type=\"text/javascript\"alert(\"用户名错误\")/script";
}
if($ps){
$_SESSION[uid]=$user;
$_SESSION[upass]=$row[password];
header("Location:index.html");
}else{
$b=FALSE;
echo "script type=\"text/javascript\"alert(\"用户名或者密码错误\")/script";
echo 'script language="JavaScript"window.location.href="login.html";/script';
}
}else{
echo "script type=\"text/javascript\"alert(\"用户名不能为空格\")/script";
echo 'script language="JavaScript"window.location.href="login.html";/script';
}
}
?
以上是userlogin.php文件,其中引用的conn.php文件代码如下:
其中数据库自己建一个,注册页面大体也相同,你理解了这个,就自己能写注册页面了
?php
@header('Content-Type: text/html; charset=utf-8');
@session_start();
$conn = @ mysql_connect("127.0.0.1", "zznt", "19880210") or die("数据库连接错误");
mysql_select_db("zznt", $conn);
//mysql_query("set NAMES 'utf8'");
//mysql_query("set character_set_client=utf8");
//mysql_query("set character_set_results=utf8");
mysql_query("set NAMES 'utf8'");
mysql_query("set character_set_client=utf8");
mysql_query("set character_set_results=utf8");
//$content=str_replace("'","钬?,$content);
//htmlspecialchars();
?
用PHP做留言板
说了的啊,就让你编写三个文件
post.php 文件
index.html 文件
display.inc文件
就是把上面的代码分别复制到记事本中在按上面的文件名保存
在放到你的网站目录下就可以了
