undefined index issue even when data is in the array in codeigniter

Question

I am accessing an array object being transferred from model to view. When I print that array it shows complete info what I want, but when I implement foreach on that array and try to access an index it gives me an error of undefined index.

the model code is

public function fetch()
        {

$queryy=$this->db->select('*')
            ->from('selleritem')
            ->get();
            $data=$queryy->result();

            foreach($data as $datas)
            {
                $pid=$datas->pid ;
$query= $this->db->limit('1')
->select('*')
     ->where('pid', $pid)             
  ->get('selleritemimages'); 

    if($query->num_rows() > 0){
         foreach ($query->result() as $row)
         {
            $data[] = $row;
         }
        return $data;
        //print_r($data);
    }
}

the controller code is:

public function index()
    {

        $this->load->model('fetchindex');

        $fetch= array($this->fetchindex->fetch());  

        $this->load->view('welcome_message',['fetch'=>$fetch]);

    }
}

the view code is printing the array in view shows .

print_r($fetch);

    foreach ( $fetch as $ff) {

    echo $ff["pid"].'hh<br>';

    }

printing the array in view shows .

Because it is Codeigniter Object, not an Array. And also see that your result object array is inside 0 index. So, try fetching and getting data this way.

<?php foreach ( $fetch[0] as $ff) { 
     echo $ff->pid;
} ?>

Thank You.

Try your foreach like this:

foreach ($fetch[0] as $ff)
{
     echo $ff["pid"].'hh<br>';
}

Try this:

$objects = json_decode($fetch);
$finalResult = (Array)$objects[0];
foreach($finalResult as $result){
    echo $result->pid.'<br />';
}

Thank you for this code snippet, which may provide some immediate help. A proper explanation would greatly improve its educational value by showing why this is a good solution to the problem, and would make it more useful to future readers with similar, but not identical, questions. Please edit your answer to add explanation, and give an indication of what limitations and assumptions apply.

Try $query->result_array() instead of $query->result() If you read through the entire user guide, it should answer a few of your questions.

Better way

$this->load->model('fetchindex');

$data['fetch'] = $this->fetchindex->fetch();  

// You can load views like so instead of using includes on view.
$this->load->view('header');
$this->load->view('welcome_message',  $data);
$this->load->view('footer');

Model

Filename: Fetchindex.php

<?php 

class Fetchindex extends CI_Model {

public function fetch()
{
    $data = array();

    $query = $this->db->get('selleritem');

    foreach ($query->result() as $result)
    {
        $this->db->where('pid', $result->pid);
        $this->db->limit(1);
        $sub_query = $this-db->get('selleritemimages');

        if ($sub_query->num_rows() > 0) 
        {

            foreach ($sub_query->result_array() as $row)
            {
                $data[] = array(
                   'somecolumn' => $row['somecolumn']
                   // Add other items you need
                );

            }
        }
    }

    return $data;
}

}

View

<?php foreach ($fetch as $item) {?>
     <?php echo $item["somecolumn"];?><br/>
<?php }?>
