web编程 留言板代码实现留言板输入和查看…

其实这个挺简单的，代码如下留言板输入代码，在form表单中插入： textarea name="liuyan" rows="4" cols="60" /textarea查看留言的代码：//下面方法trans的作用是将string中的回车符号换位br 下面有两种方法%!string trans(String str){str=str.replace("\n", "br");return str;}%或者%!StringBuffer trans(StringBuffer str){for(int i=0;istr.length();i++){if(str.substring(i,i+1).equal("\n")){str.delete(i,i+1);str.insert(i,"br");}}return str;}% String str=request.getParameter("liuyan");//获取form表单提交的留言 str=trans(str);// 调用第一个方法 StringBuffer str=new StringBuffer(str); str=trans(str);//调用第二种方法 out.println(" 你的留言是br"+str); 以上代码就可以实现留言板输入和查看啦 希望能解决你的问题啊

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
