A PHP Error was encountered

Severity: Notice

controller:

PHP Code:

        $this->template->load('users/index', array('users' => $data));
    } 


Model:

PHP Code:

public function get_all($limit,$start){
        return $this->db->get('users', $limit, $start)->result_array();
    }

        <td><?=$value['email'];?></td>
        <td><?=$value['status'];?></td>
        <td><?=$value['access'];?></td>
    </tr>
<?php endforeach; ?>

I think this is the problem. When you pass 'users => $data, the array $users contains

Code:

$users['result'] => array() of users
$users['link'] => array() of links

When you say foreach ($users as $key => $value), the first time, $key will contain 'result' and $value will contain the array of users, not a single user.

It may work if instead you just pass the $data array. Then your view will have two arrays, $result and $link. Then you can go foreach ($result as $key => $value).

Well, I hope that's the answer.

Hey, don't work without a PHP debugger. Several free IDEs have this features built in. Two are NetBeans and CodeLobster. Without a debugger, it's like you're driving with a blindfold on -- you are going to crash!

hi
now this is new error:

A PHP Error was encountered

Severity: Notice

Message: Undefined variable: result

Filename: users/index.php

Line Number: 43

P.S. after setting up pagination library in controller, the foreach doesn't have any problem and show data in table.

Hi. Does your last line mean that you solved your problem? If not, try using a var_dump to see what is in the array that you pass. If you are using
$this->template->load('users/index', array('users' => $data)); in your controller
then put in your view something like this

Code:

var_dump($users);
exit;
<?php foreach($users as $key => $value):?>

Also, $this->template->load is not documented for CI 2 or CI 3. The documentation refers to $this->template->parse. Are you using a third-party library of some kind? I'm just curious because using that is not giving you an error.

no i still have the problem. i'm using a template library. could you remote to my pc please?

the result after using var_dump:

array (size=2)
'result' =>
array (size=0)
empty
'link' => string '&nbsp;<strong>1</strong>&nbsp;<a href="http://localhost/ci_pmanagement/admin/index.php/user/page/1">2</a>&nbsp;<a href="http://localhost/ci_pmanagement/admin/index.php/user/page/1">&gt;</a>&nbsp;' (length=195)

array (size=2)
 'result' =>

     empty
 'link' => string '&nbsp;<strong>1</strong>&nbsp;<a href="http://localhost/ci_pmanagement/admin/index.php/user/page/1">2</a>&nbsp;<a href="http://localhost/ci_pmanagement/admin/index.php/user/page/1">&gt;</a>&nbsp;' (length=195)

I can't remote to your PC, but from the var_dump you have, there is nothing in your result array. That means that your get_all() function in your model is not returning any rows.

Code:

$config['per_page'] = 1;
$page = ($this->uri->segment(4))?$this->uri->segment(4):0;

$data['result'] = $this->user_model->get_all($config['per_page'], $page);

public function get_all($limit,$start){
    return $this->db->get('users', $limit, $start)->result_array();
}

Use var_dump to see what's in the $page variable just before you call the get_all() function, and use var_dump to see what's in the $data['result'] array when the get_all() function returns.

please check that

var_dump($users)

array (size=2)
'result' =>
array (size=1)
0 =>
array (size=6)
'id' => string '1' (length=1)
'username' => string 'admin' (length=5)
'password' => string 'e10adc3949ba59abbe56e057f20f883e' (length=32)
'email' => string 'admin@localhost.com' (length=19)
'status' => string '1' (length=1)
'access' => string '1' (length=1)
'link' => string '&nbsp;<strong>1</strong>&nbsp;<a href="http://localhost/ci_pmanagement/admin/index.php/user/page/1">2</a>&nbsp;<a href="http://localhost/ci_pmanagement/admin/index.php/user/page/2">3</a>&nbsp;<a href="http://localhost/ci_pmanagement/admin/index.php/user/page/1">&gt;</a>&nbsp;&nbsp;<a href="http://localhost/ci_pmanagement/admin/index.php/user/page/3">Last</a>' (length=360)

var_dump($result):

You're right -- the result variable does contain data, so it shouldn't be undefined. What's happening is that variables in your controller are not visible within your view for some reason. I think the problem must be in the third-party template library. Could you try using Codeigniter's $this->load->view('users/index', $users) just to see if you can access the result variable that way?
