Add div around validation_errors

Question

Hi i want to edit my validation_errors function that it will always have a div around it. Im using bootstrap and there is a nice way to show errors with Dismissable alerts Look here

I have found the function validation_errors() in system/helpers/form_helper.php which looks like:

if ( ! function_exists('validation_errors'))
{
    function validation_errors($prefix = '', $suffix = '')
    {
        if (FALSE === ($OBJ =& _get_validation_object()))
        {
            return '';
        }  
        return $OBJ->error_string($prefix, $suffix);
    }
}    

How can i edit it that it returns :

     <div class="alert alert-danger alert-dismissable">
        errors here
     </div>

I know i shouldn't do it in a helper class because its bad when i update my codeigniter version, but i really do not know how it can be done in a diffrent way.

Have you tried

if ( ! function_exists('validation_errors'))
{
    function validation_errors($prefix = '', $suffix = '')
    {
        if (FALSE === ($OBJ =& _get_validation_object()))
        {
            return '';
        }  
        return '<div class="alert alert-danger alert-dismissable">'.$OBJ->error_string($prefix, $suffix).'</div>'
    }
}  

or

<?php 
if(!empty(validation_errors())) {
   echo '<div class="alert alert-danger alert-dismissable">'.validation_errors().'</div>';
}
?>

or if you really need to modify the helper

if ( ! function_exists('validation_errors'))
    {
        function validation_errors($prefix = '', $suffix = '')
        {
            if (FALSE === ($OBJ =& _get_validation_object()))
            {
                return '';
            }

            if($OBJ->error_string($prefix, $suffix) != '') {
              return '<div class="alert alert-danger alert-dismissable">'.$OBJ->error_string($prefix, $suffix).'</div>';
            }
            else {
              return '';
            }
        }
    }
