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。1. 创建测试数据库和表
create database `guru`; USE `guru`; CREATE TABLE `employees` ( `id` int(6) NOT NULL auto_increment, `name` char(20) default NULL, `lastname` char(20) default NULL, `salary` float default NULL, `age` int(2) default NULL, `afiliation` date default NULL, `status` int(1) default NULL, `active` tinyint(1) default NULL, `workeddays` int(2) default NULL, `photo` char(30) default NULL, 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 = new datagrid; $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<Select>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<CheckBox>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 "<html> <head><title>PHPDataGrid</title></head> <body><div align="center"><br />"; //生成DataGrid $objGrid->grid(); echo "</div></body></html>";//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。
以上就是教大家PHP如何直接修改表内容DataGrid功能的全过程，还有对数据库的了解，希望本文对大家的学习有所帮助。
