How to use user_id to get users details from database and display them

I'm making a website on the CodeIgniter framework so users can add products to the website. Now my question is: How do I use the user_id in the products table to get the user's details from the database and display them next to the product? So for example when I click on a product I want to have a link to the profile of the user who uploaded the product but I'm not sure how I can do that.

Database tables information:

table users:

user_id (primary_key)
email
voornaam
achternaam
beschrijving


table products:

product_id (primary_key)
product_naam
product_beschrijving
user_id
category_id

My function in model file:

public function get_product_details($product_id) {
    $this->db->select('products.*, users.*');
    $this->db->from('products');
    $this->db->join('users', 'users.user_id = products.user_id', 'left');
    $this->db->where('product_id', $product_id);
    $query = $this->db->get();
    $result = $query->row_array();
    if (!empty($result)) {
        return $result;
    } else {
        return array();
    }
}

Use join query based on user_id fetch details from 2 tables in database.

Like this:

Model:

public function get_product_details($product_id)
{
    $this->db->select('users.user_id,users.email,users.voornam,products.product_id,products.category_id,products.product_naam');
    $this->db->from('users');
    $this->db->join('products','products.user_id = users.user_id');
    $this->db->where('product_id', $product_id);
    $query = $this->db->get();
    if($query->num_rows()>0)
    {
       return $query->result_array();
    }
}

Controller:

public function edit($product_id)
{
    $data['products_list'] = $this->your_model->get_product_details($product_id);
    $this->load->view('your_view_filename',$data);
}

// data from $data['products_list'] in controller.

View:

<?php print_r($products_list); //for refference
    foreach($products_list as $row)
                    {
                    ?>
                    <tr>
                        <td><?php echo $row['email'];?></td>
                        <td><?php echo $row['voornam'];?></td>
                        <td><?php echo $row['product_naam'];?></td>
                            etc...
                     </tr>
   <?php } ?>
