PHP directly modifies table content DataGrid function implementation code_php skills

Since it needs to be connected to Oracle, I personally feel that phpMyDataGrid is relatively easy to get started with in terms of secondary development and page style.
1. Create test database and tables

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. Introduction to PHP program

phpMyDataGrid is mainly implemented through phpmydatagrid.class.php and dgscripts.js. The total size is less than 100kB, and it is a small software. I won’t go into detail about these two documents. Interested students can “pack them away” and go back to read them slowly. It mainly introduces how to use the software, that is, the example datagrid_for_mysql.php. Let’s take a look at the page diagram first:

Procedure explanation:

<&#63;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:&euro;");//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(); 
&#63;> 

3. Based on Oracle introduction

To read Oracle, you mainly need to modify the function connecting to MySQL in phpmydatagrid.class.php to Oracle. This article is an Oracle connection through sqlrelay. Of course, you can also use the OCI8 module that comes with PHP (the efficiency is somewhat low ), after modification, save it as phporadatagrid.class.php and then call it in other programs (datagrid_for_oracle.php).

The above is the whole process of teaching you how to directly modify the table content of the DataGrid function in PHP, as well as the understanding of the database. I hope this article will be helpful to your study.
