Get specific row from database with codeigniter - codeigniter

Question

I'm new to this so i have this silly question.I want to make a login form and when the user logs in i want to show all his information in the screen(username attack defence...).The thing is i don't know how to call the specific function i've made because in my controller calls function index() by default and not the function guser().
login view
<h2>Login</h2>
<?php if($error==1){ ?>
<p>Your Username/password did not match </p>
<?php } ?>
<form action="<?=base_url()?>index.php/Users/login" method="post">
<p>Username: <input name="user" type="text" /> </p>
<p>Password: <input name="password" type="password" /> </p>
<p><input type="submit" value="Login" /></p>
</form>
users controller
<?php
class Users Extends CI_Controller{
function __construct(){
parent::__construct();
$this->load->model('User');
}
function index(){
$data['users']=$this->User->get_users();//sto model post tha kalesei tin sinartisi get_posts
$this->load->view('Post_index',$data);
}
function guser($id){
$data['user']=$this->User->get_user($id);
$this->load->view('Post_index',$data);
}
function login(){
$data['error'] = 0; // simenei oti den exei errors
if($_POST){
$user=$this->input->post('user',true);//pairnei to username p edose o xristis(einai idio me to $_POST)
$password=$this->input->post('password',true);//pairnei to password p edose o xristis
//$type=$this->input->post('charact',true);
$user1=$this->User->login($user,$password);//,$type);
if(!$user1){
$data['error']=1;
}else{
$this->session->set_userdata('id',$user1['id']);
$this->session->set_userdata('user',$user1['user']);
$this->session->set_userdata('name',$user1['name']);
$this->session->set_userdata('money',$user1['money']);
$this->session->set_userdata('attack',$user1['attack']);
$this->session->set_userdata('defence',$user1['defence']);
$this->session->set_userdata('level',$user1['level']);
$this->session->set_userdata('xp',$user1['xp']);
redirect(base_url().'index.php/Users');
}
}
$this->load->view('Login',$data);
}
function registerSam(){
if($_POST){
$data=array(
'user'=>$_POST['user'],
'name'=>$_POST['name'],
'password'=>$_POST['password'],
'charact'=>"Samurai",
'money'=>400,
'attack'=>10,
'defence'=>5,
'level'=>0,
'xp'=>0
);
$userid=$this->User->create_user($data);
}
}
function registerKnight(){
if($_POST){
$data=array(
'user'=>$_POST['user'],
'name'=>$_POST['name'],
'password'=>$_POST['password'],
'charact'=>"Knight",
'money'=>400,
'attack'=>5,
'defence'=>10,
'level'=>0,
'xp'=>0
);
$userid=$this->User->create_user($data);
}
}
}
?>
user model
<?php
class User Extends CI_Model{
function create_user($data){
$this->db->insert('unityusers',$data);
}
function login($user,$password){
$where=array(
'user'=>$user,
'password'=>$password,
);
$this->db->select()->from('unityusers')->where($where);
$query=$this->db->get();
return $query->first_row('array');
}
function get_user($id){
$this->db->select()->from('unityusers')->where(array('id'=>$id));
$query=$this->db->get();
return $query->first_row('array');
}
function get_users($num=20,$start=0){// tha paroume 20 posts k tha arxisoume apo to proto
$this->db->select()->from('unityusers')->limit($num,$start);
$query=$this->db->get();
return $query->result_array();
}
}
?>

Answer 1

Although you have accepted the answer I like to point out some basic functionality for you to more improved code.
Different technique to load the data to view from controller:
function index(){
$users = $this->User->get_users();
$this->load->view('Post_index',['users' => $users, 'any_other_data' => $any_other_data ... and so on]);
}
When you get post data in the controller then you should check for a validation first inside your login function. And in login functionality it will be more useful. setting-validation-rules
$this->form_validation->set_rules('username', 'Username', 'required');
$this->form_validation->set_rules('password', 'Password', 'required',
Loading a model and it's function. You don't need to use uppercase in this as give below.
$this->load->model('user');
$this->user->get_users();
Your registration Function registerSam you don't need to create an array of post data Codeigniter will provide the functionality to get all your post data at once. To remove unnecessary data from that array use unset.
$your_post_array = $this->input->post();

Answer 2

To call a specific function made, you can access it via a browser using the link
BASE_URL/index.php/ControllerName/MethodName
So, in your case to call the guser method, the url would be
BASE_URL/index.php/users/guser
Hope that helps.

Answer 3

You have an error in guser function on the controller. You don't need to passs any argument to the function. You can get ID of user from the session, which was actually added in session once the user has entered correct credentials.
Also after login, you need to redirect user to guser function instead of users. Because as per your controller users function dosen't exist.
Change From
redirect(base_url().'index.php/Users');
To
redirect(base_url().'index.php/guser');
Please check below for solution.
function guser(){
$data['user']=$this->User->get_user($this->session->userdata('id'));
$this->load->view('Post_index',$data);
}
Let me know if it not works.
