最近想做一个通过PHP实现DataGrid功能的东西，这样可以直接修改数据库中表的内容，而不用开发【新增数据页面】，【编辑页面】，于是乎在网上找了找，类似的东西也有几个，开源的、付费的都有，不过基本都是基于MySQL。由于需要连接Oracle所以从二次开发和页面样式来说个人觉得phpMyDataGrid还是比较好上手。本篇首先介绍基于MySQL的使用方法，再简单介绍对于Oracle连接(基于sqlrelay)的二次开发。

1. 创建测试数据库和表

create database`guru`; USE`guru`; CREATE TABLE`employees` (`id` int(6) NOT NULLauto_increment,`name` char(20)defaultNULL,`lastname` char(20)defaultNULL,`salary` float defaultNULL,`age` int(2)defaultNULL,`afiliation` date defaultNULL,`status` int(1)defaultNULL,`active` tinyint(1)defaultNULL,`workeddays` int(2)defaultNULL,`photo` char(30)defaultNULL,PRIMARY KEY(`id`) ) insert into`employees` (`id`,`name`,`lastname`,`salary`,`age`,`afiliation`,`status`,`active`,`workeddays`,`photo`)values(1,'Ana','Trujillo',2000,45,'2005-05-13',1,1,10,'1.jpg');insert into`employees` (`id`,`name`,`lastname`,`salary`,`age`,`afiliation`,`status`,`active`,`workeddays`,`photo`)values(2,'Jennifer','Aniston',3500,23,'2004-10-22',1,0,0,'2.jpg');insert into`employees` (`id`,`name`,`lastname`,`salary`,`age`,`afiliation`,`status`,`active`,`workeddays`,`photo`)values(3,'Michael','Norman',1200,19,'2007-01-10',1,1,5,'3.jpg');insert into`employees` (`id`,`name`,`lastname`,`salary`,`age`,`afiliation`,`status`,`active`,`workeddays`,`photo`)values(4,'Vanessa','Black',6500,31,'2000-11-05',1,1,30,'4.jpg');insert into`employees` (`id`,`name`,`lastname`,`salary`,`age`,`afiliation`,`status`,`active`,`workeddays`,`photo`)values(5,'Michael','Strauss',3200,45,'2006-10-21',2,0,22,'5.jpg');insert into`employees` (`id`,`name`,`lastname`,`salary`,`age`,`afiliation`,`status`,`active`,`workeddays`,`photo`)values(6,'William','Brown',2300,21,'2001-03-10',3,1,10,'6.jpg');insert into`employees` (`id`,`name`,`lastname`,`salary`,`age`,`afiliation`,`status`,`active`,`workeddays`,`photo`)values(7,'Lucca','Normany',2800,36,'2006-10-02',3,1,20,'7.jpg');

2. PHP程序介绍

phpMyDataGrid主要是通过phpmydatagrid.class.php，dgscripts.js来实现的，总共加起来不到100kB，又是一个小巧的软件。对于这两个文件就不多讲了，感兴趣的同学可以“打包带走”回去慢慢品。主要介绍该软件的使用方法，即实例datagrid_for_mysql.php。先看一下页面示意图：

程序讲解：

<?php include("phpmydatagrid.class.php"); $objGrid=newdatagrid; $objGrid->closeTags(true); $objGrid->friendlyHTML(); $objGrid->methodForm("get"); //连接数据库$objGrid->conectadb("127.0.0.1","root","root","guru");

//加密字符串$objGrid->salt("Myc0defor5tr0ng3r-Pro3EctiOn"); $objGrid->language("en"); //最后一列显示的功能键，从左向右功能为“新增键”、“编辑键”、“删除键”、“浏览键”。$objGrid->buttons(true,true,true,true); //修改数值时产生的Form名称$objGrid->form('employee',true); //可检索列名$objGrid->searchby("name,lastname"); //需要读取的表$objGrid->tabla("employees"); //索引值用于修改数据$objGrid->keyfield("id"); //分页显示行数$objGrid->datarows(20); //默认排序方式$objGrid->orderby("name","ASC"); //显示列设置，相关设置可参考phpmydatagrid.class.php$objGrid->FormatColumn("id","ID Employee",5,5,1,"50","center","integer"); $objGrid->FormatColumn("name","Name",30,30,0,"150","left"); $objGrid->FormatColumn("lastname","Last name",30,30,0,"150","left"); $objGrid->FormatColumn("age","Age",5,5,0,"50","right");

//自定义日期格式$objGrid->FormatColumn("afiliation","Afiliation Date",10,10,0,"100","center","date:dmy:/");

//编辑时可以自定义为模式 $objGrid->FormatColumn("status","Status",5,5,0,"60","left","select:1_Single:2_Married:3_Divorced"); //编辑时可以自定义为模式$objGrid->FormatColumn("active","Active",2,2,0,"50","center","check:No:Yes");

//自定义货币显示形式 $objGrid->FormatColumn("salary","Salary",10,10,0,"90","right","money:€");

//将数据以柱状图显示 $objGrid->FormatColumn("workeddays","Work days",5,2,0,"50","right","chart:percent:val:31"); $objGrid->checkable(); $objGrid->setHeader(); $objGrid->ajax('silent'); echo'

PHPDataGrid ';

//关闭数据库连接 $objGrid->desconectar(); ?>

3. 基于Oracle简介

对于Oracle的读取主要是把phpmydatagrid.class.php中与MySQL连接的函数修改为Oracle，本篇是通过sqlrelay(可参考http://sqlrelay.sourceforge.net/)进行的Oracle连接，当然也可以使用PHP自带的OCI8模块(效率有些低)，修改后另存为phporadatagrid.class.php即可在其他程序(datagrid_for_oracle.php)中调用。以上涉及的所有程序均可在压缩包中找到。

希望对大家有用！
