Answer 1

Try this in ur code
//view
<tbody>
<?php for ($i = 0; $i < count($records); ++$i) { ?>
<tr>
<td><?php echo ($i+1); ?></td>
<td><?php echo $records[$i]->fname; ?></td>
<td><?php echo $records[$i]->lname; ?></td>
<td><?php echo $records[$i]->email; ?></td>
<td>Delete</td> <td>Edit</td>
</tr>
<?php } ?>
</tbody>
make sure u pass the record id to the view and base_url is configured on config file
//controller
public function row_delete(){
if(isset($_GET['id'])){
$id=$_GET['id'];
$this->load->model('Model');
$this->mod1->row_delete($id);
redirect($_SERVER['HTTP_REFERER']);}
}
//model
public function delete_row()
{
$this->db->where('id', $id);
$this->db->delete('register');
}

Answer 2

Just pass the parameters to the where function and table name to delete function:
public function delete_row()
{
// Set where
$this->db->where('id', $id);
// Run query
return $this->db->delete('register');
}
