这是一款老外写的mysql php接受数据过来然后进行数据保存在mysql_real_escape_string(nl2br(strip_tags($_POST[\'comment\'])));我觉得写得和我们有一点区别吧,代码如下:

database config.php代码如下:

$db_host  = 'localhost';

$db_user  = 'root';

$db_pass  = '';

$db_database = '';

$link = mysql_connect($db_host,$db_user,$db_pass) or die('unable to establish a db connection');

mysql_select_db($db_database,$link);

mysql_query("set names utf8");

if(emptyempty($_post['comment'])) die("0");

// if there isn't a comment text, exit

$comment = mysql_real_escape_string(nl2br(strip_tags($_post['comment'])));//开源代码phpfensi.com

$user='demo';

// this would be a nice place to start customizing - the default user

// you can integrate it to any site and show a different username.

$addon='';

if($_post['parent']) $addon=',parent='.(int)$_post['parent'];

mysql_query("insert into wave_comments set usr='".$user."', comment='".$comment."', dt=now()".$addon);

if(mysql_affected_rows($link)==1)

echo mysql_insert_id($link);

// if the insert was successful, echo the newly assigned id

else

echo '0';

sql数据库文件如下:

--

-- table structure for table `wave_comments`

--

create table `wave_comments` (

 `id` int(11) not null auto_increment,

 `parent` int(11) not null default '0',

 `usr` varchar(16) collate utf8_unicode_ci not null default '',

 `comment` text collate utf8_unicode_ci not null,

 `dt` datetime not null default '0000-00-00 00:00:00',

 primary key (`id`),

 key `parent` (`parent`,`id`)

) engine=myisam default charset=utf8 collate=utf8_unicode_ci;

insert into `wave_comments` values(5, 2, 'curious', 'thanks! also i noticed that you can click, rather than drag the slider.great!', '2009-10-24 04:11:48');
