Today we will learn about login and registration in this tutorial. How do we log in and register in PHP Codeigniter?
- First we will go to the database. And create a table.
- Registration will be made after that, we will submit the details of the user in PHP MySQL
- At the time of registration, we will check the email id that this email id is already inserted in the database. If it is inserted, then a message will be sent that email id Already Exist
- Add validation to login and registration
- Convert the user’s simple password with the hash string.
- User login form enter the system
- And the user will store the session
- Create a user profile
- Users will be logged out in a system
1-Table structure for table tblregistration
CREATE TABLE `tblregistration` ( `Id` int(11) NOT NULL, `Fristname` varchar(45) DEFAULT NULL, `Lastname` varchar(45) DEFAULT NULL, `Phoneno` varchar(45) DEFAULT NULL, `gender` varchar(45) DEFAULT NULL, `Emailid` varchar(45) DEFAULT NULL, `Password` varchar(45) DEFAULT NULL, `Create_date` timestamp NULL DEFAULT current_timestamp() ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
2-Database configuration
application/config/database.php
$active_group = 'default'; $query_builder = TRUE; $db['default'] = array( 'dsn' => '', 'hostname' => 'localhost', 'username' => 'root', 'password' => '', 'database' => 'student', 'dbdriver' => 'mysqli', 'dbprefix' => '', 'pconnect' => FALSE, 'db_debug' => (ENVIRONMENT !== 'production'), 'cache_on' => FALSE, 'cachedir' => '', 'char_set' => 'utf8', 'dbcollat' => 'utf8_general_ci', 'swap_pre' => '', 'encrypt' => FALSE, 'compress' => FALSE, 'stricton' => FALSE, 'failover' => array(), 'save_queries' => TRUE );
3-Add to Libraries and helper
application/config/Autoload.php
$autoload['libraries'] = array('database','form_validation','session','encryption');
$autoload['helper'] = array('html','url','form','captcha');
4-Add to by Default Controller set
application/config/routes.php
$route['default_controller'] = 'Login'; $route['404_override'] = ''; $route['translate_uri_dashes'] = FALSE;
5-Create a new Registration From(registration.php)
application/views/registration.php
