codeigniter form validation for dynamic form input names

Question

I have a codeigniter app. My view uses the database row ID to append to the input name to get a unique ID. this allows me to use all inputs in my form action, which is update.

Answer 1

Working solution, big thanks to @yabol on this one. I still need to clean up the syntax a little but desired functionality working.

View

'updatecustomer',
        'id'=>'updatecustomer',
        );
    echo form_open('masterdata/manage_customers',$attributes);
?>

    



    

        
 
 
Customer Name
Address Line 1
Address Line 2
Suburb
City
Postal Code
Contact Name
Contact Email
Contact Tel
    



    

        

id, img(array('src'=>'images/delete_icon.png','border'=>'0','alt'=>'Delete'))); ?>
