Question

I would like to get the ID of a value from a database and use it to delete an item.
Heres my code:

This code currently gets a set of records from a database, where each record has links. How can I do this?

<h2>List of all polls in this site:</h2>
<?php echo '<table>';?>
<table border="1">
  <tr>
    <th>Title</th>
    <th>Text</th>    

    <th colspan="2">Action</th>        
  </tr>
<?php 
foreach($polls as $polls_item){
  echo "<tr>";
    echo "<td>". $polls_item['title'] ."</td>";
    echo "<td>". $polls_item['text'] ."</td>";
    echo "<td>". anchor('user/vote/'.$polls_item->id,'Vote') ."</td>";
    echo "<td>". anchor('admin/del/'.$polls_item->id,'Delete') ."</td>";        
  echo "</tr>"; 
}
?>

<?php echo anchor('admin/del/1','Delete'); ?>

</table>

Answer 1

I will assume that you have an admin controller, and you loaded admin_model at the beginning which is where you get all your polls

class Admin
....
function del($id = null)
{
  $this->admin_model->delete($id);
} 

Then in your admin_model where polls is the table name of your database

class Admin_model
....
function delete($id)
{
 $this->db->delete('polls', array('id' => $id)); 
}

I hope this is clear enough.
