Here's a simple tip, which might save somebody a couple of minutes.
The default output of each validation error is wrapped in paragraph tags. I wanted to use list item tags.
Fortunately the Validation class defines two properties, _error_prefix and _error_suffix, which makes it easy to change them. Create an extended class (if you haven't previously done so) and define the new values in the Constructor.
Code:
class My_Validation extends CI_Validation
{
/**
* Constructor
*
*/
function My_Validation()
{
parent::CI_Validation();
$this->_error_prefix = '<li>';
$this->_error_suffix = '</li>';
}
}
