หน้าแรก PHP MySQL เกร็ดความรู้ การอัพเดทหลายแถวผ่าน checkbox ด้วย php Update multiple rows in MySQL with checkboxes

A useful method to select all checkboxes and the ability to update MySQL records with PHP.

First we create a MySQL database, next we create the update page with the checkboxes and add the PHP code to make the update possible.

Simple, easy and fast...
Enjoy!

----------------------------------------------------------------
Create the MySQL database and table.
----------------------------------------------------------------

Code

CREATE DATABASE `test`;
USE `test`;

CREATE TABLE `test_mysql` (
`id` int(4) NOT NULL auto_increment,
`name` varchar(65) NOT NULL default '',
`lastname` varchar(65) NOT NULL default '',
`email` varchar(65) NOT NULL default '',
`status` varchar(1) NOT NULL default '',
PRIMARY KEY (`id`)
) type="MyISAM" auto_increment="7" ;

--
-- Dumping data for table `test_mysql`
--

INSERT INTO `test_mysql` VALUES (1, 'Billly', 'Bob', 'bb@example.com','Y');
INSERT INTO `test_mysql` VALUES (2, 'James', 'Bell', 'jb@example.com','Y');
INSERT INTO `test_mysql` VALUES (3, 'Mark', 'Jackson', 'mj@example.com','N');
INSERT INTO `test_mysql` VALUES (4, 'Linda', 'Travorse', 'lt@example.com','Y');
INSERT INTO `test_mysql` VALUES (5, 'Joy', 'Ford', 'jf@example.com','Y');
INSERT INTO `test_mysql` VALUES (6, 'Sidney', 'Gib', 'sgib@example.com','N');
