Question

Framework : CI

Situation:

I have this very frustrating problem in codeigniter.

here is the code:
(Controller)

class sampleController extends CI_Controller {

function index() {
    data['message'] = 'something';

    data['js'] = array('script1.js', 'script2.js');
    data['css'] = array('style1.css', 'style2.css', 'style3.css');

    $this->load->model('user_model');
    $user = $this->input->post('username');

    data['user_id'] = $this->user_model->getUserIdByUsername($user);
    data['user_info'] = $this->user_model->getAllUserInfo($user);

    $this->load->view('someview', $data);

}

}

okay there goes my controller, i passed several data like js, css, user_id and user_info

here are the methods in my model:

getUserIdByUsername($user) {
$this->db->select("id");
$this->db->where("username", $user);
$result = $this->get("users");
return $result->row();

}

getAllUserInfo($user) {
$this->db->select("first_name, last_name, age");
$this->db->where("username", $user);
$result = $this->get("users");
return $result->row();
}

The problem occurs in the view, when i tried to access all the variables that has been passed by the controller

1. if i tried echoing $message, it will render out correctly like this = something

2. if i tried looping on each using foreach$js and $css like this

   foreach($js as $key){//echo script here}

   foreach($css as $key){// echo link rel stylesheet here}

it will render out correctly like <script src='script1.js'></script><script ...></script> iterate to all $js same goes with css

but if i tried echoing out $user_id . . it won’t, bec. it is an object.

so to solve for the problem what i did is . .<?php foreach($user_id as $id){} ?> i can echo $id in this case
is there anyway so that i can echo it out simple without that messy foreach.

i understandd that when i comes to $user_info, it is fine to do this foreach($user_info as $key => $value){$info[$key]=$value}
but is there a better way that doing that in the view?

maybe instead of an object, array will be sent before the view can use it?

thanks muchs

Edit: fixed same method name;

Answer 1

$result->row(); returns an object with all the selected fields. Just because you only SELECTed the id field doesn’t change the return value. Try this instead:

$data['user_id'] = $this->user_model->getUserIdByUsername($user)->id;

OR:

getUserIdByUsername($user) {
    $this->db->select("id");
    $this->db->where("username", $user);
    $result = $this->get("users");
    return $result->row()->id;
}

Check the CI docs for more information about generating query results if you want arrays instead of objects:

result_array()

This function returns the query result as a pure array, or an empty
array when no result is produced.

row_array()

Identical to the above row() function, except it returns an array.
