One user having multiple card ( php, mysql ) - php

Question

I have a question, I am trying to create a way in which the user who is logged in can register multiple cards under his name. I understand the concept but just cannot apply it. So need help.
So basically I have 2 tables one for users and another for the cards, which are as shown.
new_users
user_money
So basically i created all this table and most of the information are inserted directly by me for example the orig_id.
So basically what I just want to do is that the user logged in can create multiple cards. Maybe the new_users.id could be equal to user_money.orig_id , but I am not sure how can I make them equal to each other and when a new user registers and enters more cards how can that user id and orig id equal to each other.
This is my controller for login and the controller when user adds a card.
public function login(){
$this->load->helper('form');
$this->load->library('form_validation');
$this->form_validation->set_rules('email', 'Email', 'required');
$this->form_validation->set_rules('password', 'Password', 'required|min_length[4]|max_length[32]');
if ($this->form_validation->run() == FALSE){
$this->load->view('header_view');
$this->load->view('body_view');
$this->load->view('footer_view');
}else{
$email = $this->input->post('email');
$password = $this->input->post('password');
$this->load->model('main_page');
$user_id = $this->main_page->login_user($email, $password);
if($user_id){
$user_data = array(
'user_id' => $user_id,
'email' => $email,
'loggedin' => true
);
$this->session->set_flashdata('loggedin_success','you are loggedin');
redirect('main/Admin');
}else{
redirect('main/login');
}
}
}
And this is the function for the new card getting registered.
public function insertUserCard(){
$this->load->helper('form');
$this->load->library('form_validation');
$this->form_validation->set_rules('cardname', 'CardName', 'required');
$this->form_validation->set_rules('iban', 'IBAN', 'required');
$this->form_validation->set_rules('cc', 'CC', 'required|max_length[4]');
$this->form_validation->set_rules('amount', 'Amount', 'required');
if ($this->form_validation->run() == FALSE){
$this->load->view('header_view');
$this->load->view('admin_view');
$this->load->view('footer_view');
}else{
$data = array(
'card_type' => $this->input->post('cardname'),
'iban' => $this->input->post('iban'),
'cc' => $this->input->post('cc'),
'amount' => $this->input->post('amount'),
'orig_id' => 52
/*so the orig id here is randomly added by me */
);
$this->load->model('main_page');
$this->main_page->storeCardInfo($data);
redirect('main/Admin');
}
}
And just incase if needed the models for both the table data being inserted.
public function login_user($email , $password){
$this->db->where('email', $email);
$this->db->where('password', $password);
$result = $this->db->get('new_users');
if($result ->num_rows() == 1){
return $result->row(0)->id;
}else{
return false;
}
}
public function storeCardInfo($data){
$insert = $this->db->insert('user_money',$data);
return $insert;
}
So would like if someone could help me on how to get one user have multiple rows in the user_money table.
I am using codeigniter and mysql

Just use the user_id that is stored into $user_data inside of login().
First, to make user_data a session variable so that the whole controller can access it, change the line in login() which declares $user_data as a local variable to assign it to a session variable.
Change:
$user_id = $this->main_page->login_user($email, $password);
if($user_id){
$user_data = array(
...
To:
$user_id = $this->main_page->login_user($email, $password);
if($user_id){
$this->session->set_userdata(array(
...
Then... you can change the line in insertUserCard():
'orig_id' => 52
/*so the orig id here is randomly added by me */
to just use the session:
'orig_id' => $this->session->userdata('user_id');
I think, since you are "new to all this", you should perhaps ensure your MySQL database is setup properly with a Foreign Key Constraint. (and that you understand how that works)
