hi guys, i will share a tutorial User login in CodeIgniter.
this tutorial is very simple to implementation... follow this tutorial and if you have problem in this tutorial, you can post comment and please correction.
let's try guys..
1. Create a table users in database
CREATE TABLE IF NOT EXISTS `users` (
`uid` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(20) NOT NULL,
`password` varchar(20) NOT NULL,
`name` varchar(30) NOT NULL,
PRIMARY KEY (`uid`)
)
2. Modify file in application -> config -> autoload.php
check list code
$autoload['libraries'] = array('');
you can modify to this
$autoload['libraries'] = array('database');
3. modify file in application -> config -> routers.php
$route['default_controller'] = "welcome";
to
$route['default_controller'] = "users";
4. Create file in application -> controllers -> users.php
and type a function same with below :
function __construct() {
parent::__construct();
}
public function index()
{
$this->load->view('template');
}
5. Create file in application -> views -> template.php
<html>
<head>
<title>Create a Users</title>
</head>
<body>
<form action="<?php echo base_url(); ?>/index.php/users/" action="post">
username :<input type="text" name="users"><br/>
password :<input type="password" name="pass"><br/>
Name :<input type="text" name="name"><br/>
<input type="submit" value="Create"><br/>
</form>
</body>
</html>
6. add a code in function construct and index in application -> controller -> users.php
function __construct() {
parent::__construct();
$this->load->model('users_model');
}
public function index()
{
$param = array(
'username' => $this->input->post('users'),
'password' => $this->input->post('pass'),
'name' => $this->input->post('name'),
);
$this->users_model->create($param);
$this->load->view('template');
}
7. next, create a model in application -> models -> users_model.php
function create($param=array()){
if(!empty($param)){
$data = array(
'usersname' => $this->input->post('users'),
'password'=> $this->input->post('pass'),
'name' => $this->input->post('name'),
);
$this->db->insert('users', $data);
} else {
$this->db->insert('users', $param);
}
}
step 1 - 7 is a process create a data user.
8. now, we will show data users in database.
in add list code in application -> controller -> users.php
public function index()
{
$param = array(
'username' => $this->input->post('users'),
'password' => $this->input->post('pass'),
'name' => $this->input->post('name'),
);
$this->users_model->create($param);
//new code
$data['data_users'] = $this->users_model->findAll();
$this->load->view('template',$data);
}
9. and you add a function findAll in application -> models -> users_model.php
function findAll() {
$this->db->select('*');
$this->db->order_by('users','ASC');
$query = $this->db->get('users');
if ($query->num_rows() > 0) {
return $query->result_array();
}
}
10. and the you must add a list code in application -> views -> template.php
<html>
<head>
<title>Create a Users</title>
</head>
<body>
<form action="<?php echo base_url(); ?>/index.php/users/" action="post">
username :<input type="text" name="users"><br/>
password :<input type="password" name="pass"><br/>
Name :<input type="text" name="name"><br/>
<input type="submit" value="Create"><br/>
</form>
//new code
<table>
<tr>
<td>Username</td>
<td>Name</td>
</tr>
<?php if(isset($data_users) && count($data_users)){?>
<?php foreach ($data_users as $dtusers): ?>
<tr>
<td><?php echo $dtusers['users']; ?></td>
<td><?php echo $dtusers['name']; ?></td>
</tr>
<?php
endforeach;
else{
echo "data not found";
}?>
</table>
</body>
</html>
