set it so admin can approve a user after registration - php

Question

How do I set it up that an admin must approve a user registration...
many admins can approve many users. So if user signs up, they have to be approved before have access to a page. How would this best be done?

Answer 1

You should add one more column to user table, let's say status
Your table will look like this:
CREATE TABLE IF NOT EXISTS `user` (
`ID` int(11) NOT NULL AUTO_INCREMENT,
`fname` varchar(200) DEFAULT NULL,
`lname` varchar(200) DEFAULT NULL,
`username` varchar(200) DEFAULT NULL,
`password` varchar(200) DEFAULT NULL,
`usertype` varchar(20) DEFAULT 'm',
`status` tinyint unsigned NOT NULL DEFAULT '0',
`email` varchar(200) NOT NULL,
PRIMARY KEY (`ID`),
UNIQUE KEY `email` (`email`),
UNIQUE KEY `username` (`username`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=10 ;
When a user registers to your website, his default status will be 0, then when you approve it, status will change to 1
