PHP+MySQL实现留言板功能（三）完整版
由于前段时间过于忙碌，加上小编有重装了电脑系统，一直没有去复现这个功能，后面复现过程中，代码做了一些调整。今天我将完整版的代码和sql文件代码整理出来，供各位学习参考。
1.数据库SQL文件
index.php
登陆
doloadling.php
connect();
$sql = "select * from tbl_ms where username='$id' and password='$password'";
$res = $ma1->CheckUser($link,$sql);
if($res){
header("Location:add.php");
};
if(!$res){
echo "";
};
?>register.php
注册
doregister.php
connect();
$id=$_POST['id'];
$password=$_POST['password'];
$confirmPassword=$_POST['confirmPassword'];
if($password!=$confirmPassword){
echo "";;
}
$alt="select * from tbl_ms where username='$id'";
$res = $ma1->print1($link,$alt);
if($id!=null&&$password!=null){
$ma=new DB();
$link=$ma->connect();
$sql = "insert into tbl_ms (username,password) values('$id','$password')";
for ($i=0; $i < count($res); $i++) {
if($id!=$res[$i]['username']){
$res = $ma->insert($link,$sql);
};
if($id==$res[$i]['username']){
echo "";
}
}
}
else{
echo "";
}
?>
add.php
我的留言板.添加留言
我的留言板
doAdd.php
connect();
$sql = "insert into tbl_ms1 (user,title,author,ip,liuyan,time) values('$id','$title','$author','$ip','$content',now())";
if($title!=null){
if($author!=null){
$res = $ma1->insertl($link,$sql);
};
if($author==null){
echo "";
};
};
if($title==null){
echo "";
};
?>show.php
我的留言板.查看留言
我的留言板

$que=mysqli_query($link,$sql);
if($que){

?>connet.php

}
function CheckUser($link,$sql){
$result = mysqli_query($link,$sql);
$row = mysqli_num_rows($result);
if($row != 0){
return true;

else{
return false;
}
}
function insertl($link,$sql){
if (mysqli_query($link, $sql)) {
echo "";
} else {
echo "Error insert data: " . $link->error;
}
}
function print1($link,$sql){
