Codeigniter pagination error - codeigniter

Question

I am doing pagination in in my page, but I am getting error like this.
A PHP Error was encountered
Severity: Notice
Message: Undefined property: Home::$login_model
Filename: controllers/home.php
Line Number: 41
Fatal error: Call to a member function getDet() on a non-object in
C:\xampp\htdocs\picasso\new_design\photo_frame\application\controllers\home.php
on line 41
This is my code
Model:
function getDet(){
$query_str = "SELECT * FROM frame";
$result = $this->db->query($query_str);
return $result;
}
Controller:
public function frame1()
{
$things = $this->login_model->getDet();
$total_rows = $things->num_rows();
$this->load->library('pagination');
$config['base_url'] = base_url() . 'home/';
$config['total_rows'] = '$total_rows';
$config['per_page'] = '1';
$this->pagination->initialize($config);
$this->view_data['pagination'] = $this->pagination->create_links();
$this->view_data['things'] = $things;
$this->load->model('login_model');
$data1['wood']=$this->login_model->getDetails('wood');
$this->load->view('frame1',$data1);
}
View:
<div>
<?php if($wood!=""||$wood!=null){foreach($wood as $row){ ?>
<div class="frm1" style="border:1px solid rgb(204, 204, 204); background-color: rgb(244, 244, 244);list-style-type:none; float:left; display:inline; padding:20px;">
<img src="<?php echo base_url()."uploads/frame/icon/".$row['iconimage'];?>" style="cursor:pointer" class="changemount" data-id="<?php echo base_url()."uploads/frame/".$row['frameimage'];?>"
data-price="<?php echo $row['price'];?>" data-thick="<?php echo $row['thickness'];?>" data-change="0" data-w="515" data-h="356" data-ch="385" data-cw="554" /></div>
<?php }} ?>
</div>
<?php echo $pagination; ?>
</div>

Answer 1

You have to load the model, before using it.
public function frame1() {
$this->load->model('login_model'); //You have to load this model, before use it
$things = $this->login_model->getDet(); $total_rows = $things->num_rows();
$this->load->library('pagination');
$config['base_url'] = base_url() . 'home/';
$config['total_rows'] = '$total_rows';
$config['per_page'] = '1';
$this->pagination->initialize($config);
$this->view_data['pagination'] = $this->pagination->create_links();
$this->view_data['things'] = $things;
$data1['wood']=$this->login_model->getDetails('wood');
$this->load->view('frame1',$data1);
}

Answer 2

undefined login_model, means you call the model without loading it, add this to your _construct in controller
$this->load->model("model_name");
and also in your view you miss something important, to execute your code in loop do the code below
//add the ->result() in your var $wood
foreach($wood->result() as $row)
this will fix your error
