Save List Box Values in Many Tables

[eluser]shahmy[/eluser]
Hi, I have 2 list boxes in my view. I am moving selected list box values from left to right,
I want to know, "how to save the right list box values in table ?". If any one know, Please help me.
Thank You.

Name your list box "as array" like:

Code:

<select name="right_side[]" multiple>
...
</select>

after posting your form (ie. with method="POST") you have $_POST['right_side'] which is an array with values from select. You can do:

Code:

foreach($_POST['right_side'] as $v)
{
$this->db->insert('your_table', array('right_value'=>$v));
}

Of course this is a sample code. right_value from insert query is a field in your database table.
