HELP joining tables...
#1

[eluser]chazy (aldever calvo)[/eluser]
hello i really need help in joining tables for my get function
i have 3 tables:


user
-----
user_id(pk)
user_type_id(fk)
user_det_id(fk)

user_type
---------
user_type_id(pk)

user_details
------------
user_det_id(pk)


i had it joined and successfully output the result... but the problem is... i cannot do pagination with it...
my past code is this

Code:
function GetAllDetails()
    {
            
        $q = "SELECT A.user_id, A.uname, A.user_type_id, D.user_det_id, D.lname, D.fname, D.mname, D.email, T.user_type_name FROM user as A LEFT JOIN user_details as D ON A.user_id = D.user_det_id LEFT JOIN user_type as T ON A.user_type_id = T.user_type_id";
        $query = $this->db->query($q);
        
        return $query->result();
    }

and so what i did is change it into:
Code:
function GetAllDetails()
    {
        $this->db->join('choy_user_details', 'choy_user.choy_user_id = choy_user_details.choy_user_det_id');
        $this->db->join('choy_user_type', 'choy_user.choy_user_type_id = choy_user_type.choy_user_type_id', 'left');
        $this->db->where('choy_user_id', $userId);
        $query = $this->db->get('choy_user');
        
    
        return $query->result();
    }

But i have errors:

A PHP Error was encountered

Severity: Notice

Message: Undefined variable: userId

Filename: models/user_model.php

Line Number: 45

A PHP Error was encountered

Severity: Warning

Message: preg_match() expects parameter 2 to be string, object given

Filename: database/DB_driver.php

Line Number: 616


Please help me...

The first error means that the variable $userId is not defined.
I see it here:
$this->db->where('choy_user_id', $userId);

And the second error means that your preg_match function is receiving a wrong parameter, it should be text but you've sent an object, maybe something like $this->input when it must be $this->input->post('test'), check the second parameter of it somewhere.

the second error about the pregmatch is already solved... the first error which is about the userId... I still can't fix it....

Code:
function GetAllDetails()
    {
        $this->db->join('user_details', 'user.user_id = user_details.user_det_id');
        $this->db->join('user_type', 'user.user_type_id = user_type.user_type_id', 'left');
        $this->db->where('user_id', $userId);
        $query = $this->db->get('user');
        
    
        return $query->result();
    }

A PHP Error was encountered

Severity: Notice

Message: Undefined variable: userId

Filename: models/user_model.php

Line Number: 45


this is for my controller...
Code:
function index()
{
$data['users'] = $this->user_model->GetAllDetails();
$this->load->view('users/users_index', $data);
}

i can't seem to find a way why i have error Undefined variable: userId
even if i do it this way

$data['users'] = $this->user_model->GetAllDetails($userId);

Code:
function GetAllDetails($userId)
    {
        $this->db->join('user_details', 'user.user_id = user_details.user_det_id');
        $this->db->join('user_type', 'user.user_type_id = user_type.user_type_id', 'left');
        $this->db->where('user_id', $userId);
        $query = $this->db->get('user');
        
    
        return $query->result();
    }

and this in my controller

Code:
function index()
{
$data['users'] = $this->user_model->GetAllDetails($userId);    
$this->load->view('users/users_index', $data);
}

Where is $userId coming from? Is it in the URL?

No it's a model, but i guess he's calling this method without the first parameter or it's null.

[eluser]chazy (aldever calvo)[/eluser]
