index.php contiene el logueo y una funcion que llama el registro.php
base de dato
-- Base de datos: `account`
CREATE TABLE IF NOT EXISTS `account` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`login` varchar(30) NOT NULL DEFAULT '',
`password` varchar(45) NOT NULL DEFAULT '',
`real_name` varchar(16) NOT NULL DEFAULT '',
`email` varchar(64) NOT NULL DEFAULT '',
PRIMARY KEY (`id`),
UNIQUE KEY `login` (`login`)
) ENGINE=MyISAM DEFAULT CHARSET=big5 AUTO_INCREMENT=7591 ;
codigo de registro.php
Código PHP:
//conexion a base de dato
<?php require_once('Connections/conexion_user.php'); ?>
//validador de registro
<?php
