ThinkPHP implements the sign-in function, and thinkphp implements sign-in.

This article describes how thinkPHP implements the sign-in function. We will share this with you for your reference. The details are as follows:

Data Table:

Create table 'members _ sign' ('id' int (11) unsigned not null AUTO_INCREMENT, 'uid' int (11) unsigned not null comment 'user id ', 'Days 'tinyint (2) unsigned not null default '0' comment' consecutive sign-In days ', 'is _ share' tinyint (1) unsigned not null default '0' comment' whether shared ', 'is _ sign' tinyint (1) unsigned not null default '0' comment' whether checked in ', 'stime' int (11) unsigned not null default '0' comment' check-in time', 'atime' int (11) unsigned not null default '0' comment' add time ', primary key ('id'), KEY 'index _ uid' ('uid') using btree) ENGINE = InnoDB AUTO_INCREMENT = 162 default charset = utf8 COMMENT = 'sign in to the sharing table ';

Controller:

<?
