How to change input name and db name? - forms

Question

I build a registration form with CodeIgniter. I have a question.
As an example, one of the field from my form
<input type="text" name="username">
But in database, I will use another name instead of username such as user. How do I do it?
So, on the form it will be username, but in the database its name will be user.

Answer 1

Will clear the whole flow (comments may help to understand better)
View:
<form action="/user/register" method="post">
<input name="username" type="text" />
<input name="pass" type="password" />
<input name="age" type="text" />
<input type="submit" />
</form>
Controller:
<?php
class User extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model('user_model');
}
public function register()
{
if($this->input->server('REQUEST_METHOD') == 'POST')
{
// if validation success
if($validation)
{
/*
Mapping form fields with DB fields
Assuming below as fields in DB
user, password, age
*/
$data['user'] = $this->input->post('username');
$data['password'] = $this->input->post('pass');
$data['age'] = $this->input->post('age');
// Add user
$this->user_mode->add_user($data);
}
}
}
}
Model:
<?php
class User_model extends CI_Model
{
public function __construct()
{
parent::__construct();
$this->db = $this->load->database('default',true);
}
public function add_user($data)
{
$this->db->insert('users', $data);
}
}
To understand please read the Active Record section of CI User manual.
