This article mainly introduces the steps and methods to implement the message board function in PHP. Has very good reference value. Let’s take a look with the editor below
Simple PHP message board production
To make the basic message board function, you need three tables:
Employee table, message table, friend table
First create a login page:
<form action="drcl.php" method="post"> <p>帐号：<input type="text" name="zhang"/></p> <p>口令：<input type="text" name="mi"/></p> <input type="submit" value="登入"/> </form>
Above picture:
No need to say much, nothing wrong
Then write the processing page:
<?php
session_start();
//session存储数据
include ("db.class.php");
//引用类
$db = new db();
//造方法
$zhang = $_POST["zhang"];
$mi = $_POST["mi"];
$sql = "select mi from yuangong WHERE zhang = '{$zhang}'";
$arr = $db->Query($sql);
if(!empty($mi)&&$mi = $arr &&!empty($zhang))
{
$_SESSION["zhang"] = $zhang;
//即将跳转页面之前，把帐号存到session里面
header("location:zym.php");
}
else
{
echo "登入失败了";
}
?>
The normal login page is just to save the account for a session
Log in and enter the main page
Then comes the main page:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>无标题文档</title>
</head>
<body>
<h1>留言板</h1>
<p><a href="fbym.php" rel="external nofollow" >发布信息</a></p>
<p><a href="ddrr.php" rel="external nofollow" rel="external nofollow" onclick=" return confirm('注销当前用户？')">注销登入</a></p>
<table border="1" cellpadding="0" cellspacing="0" width="100%">
<tr>
<td>发件人</td>
<td>收件人</td>
<td>发布时间</td>
<td>内容</td>
</tr>
<?php
session_start();
//存储数据
if(empty($_SESSION["zhang"]))
{
header("location:ddrr.php");
//防止输入网址进入
exit;
}
$zhang = $_SESSION["zhang"];
include ("../db.class.php");
$db = new db();
$sql = "select name from yuangong WHERE zhang = '{$zhang}'";
$attr = $db->Query($sql);
//取到登入的name
echo "<h5>欢迎你：{$attr[0][0]}</h5>";
//输出登入的name
$sql = "select * from liuyan WHERE shou = '{$zhang}' or shou = 'all' ORDER BY times DESC ";
//条件！！我只看自己或所有人的
$arr = $db->Query($sql);
foreach ($arr as $v){
$shou = aname($v[2]);
$fa = aname($v[1]);
//用方法
echo "<tr>
<td>{$fa}</td>
<td>{$shou}</td>
<td>{$v[3]}</td>
<td>{$v[4]}</td>
</tr>";
}
//返回姓名
function aname($zhang)
{
global $db;
//设置全局变量！
if($zhang == "all")
{
//如果接收到的是all，显示：
return "所有人";
}
else
{
//如果是自己的，根据帐号查name
$sql = "select name from yuangong WHERE zhang ='{$zhang}' ";
$arr = $db->Query($sql);
//二维数组
return $arr[0][0];
}
}
?>
</table>
</body>
</html>
The search condition is to only search for your friends or everyone of all
Also note that the calling db should be set as a global variable
Picture:
The message board needs to publish information:
Publish information page:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>无标题文档</title>
</head>
<body>
<h1>发布信息</h1>
<?php
session_start();
//存储数据
if(empty($_SESSION["zhang"]))
{
header("location:ddrr.php");
//防止输入网址进入
exit;
}
$zhang = $_SESSION["zhang"];
include ("../db.class.php");
$db = new db();
$shaoyou = "select * from firend WHERE me = '{$zhang}'";
$ahaoyou = $db->Query($shaoyou);
?>
<form action="fbcl.php" method="post">
<p> 接收人:
<select name="shou">
<option value="all">所有</option>
<?php
foreach ($ahaoyou as $v)
{
$name = aname($v[2]);
echo "<option value='{$v[2]}'>{$name}</option>";
}
?>
</select></p>
<br/>
<p>留言内容: <input type="text" name="lynr"/></p>
<br/>
<input type="submit" value="发送"/>
<input type="reset" value="清空"/>
</form>
<?php
function aname($zhang)
{
global $db;
//设置全局变量！
if($zhang == "all")
{
//如果接收到的是all，显示：
return "所有人";
}
else
{
//如果是自己的，根据帐号查name
$sql = "select name from yuangong WHERE zhang ='{$zhang}' ";
$arr = $db->Query($sql);
//二维数组
return $arr[0][0];
}
}
?>
<a href="zym.php" rel="external nofollow" >查看信息</a>
<a href="ddrr.php" rel="external nofollow" rel="external nofollow" onclick="return confirm('确定要退出此帐号？')">注销登入</a>
</body>
</html>
##The last is the processing page for publishing information:
<?php
session_start();
$uid = $_SESSION["zhang"];
include("../db.class.php");
$db = new db();
$jsr = $_POST["shou"];
$neirong = $_POST["lynr"];
$sj = date("Y-m-d H:i:s");
$sql = "insert into liuyan values('','{$uid}','{$jsr}','{$sj}','{$neirong}',0)";
if($db->Query($sql,0))
{
header("location:zym.php");
}
else
{
echo "发布失败！";
}
