validation errors output

[eluser]kirkaracha[/eluser]
I display the errors at the top of my form views like this:

Code:

<?php if(isset($page_type) && $page_type=='form'){
    $this->load->view('shared/display_error_messages',$data);
    // don't show the required fields notice on deletion confirmation forms
    if(!strpos($page_title,'delete')) {
        echo '<p class="note"><strong>Bold</strong> fields are required.</p>' . "\r\r";
    }
} ?&gt;

The shared/display_error_messages view:

Code:

<?php
if(isset($this->validation->error_string)){
    if(count($this->validation->_error_array) > 0) {
        $display = '<div id="errors">' . "\r\r";
        $display .= "<p>Sorry, we had some trouble with your form.</p>\r\r";
        $display .= "<ul>\r";
        $display .= $this->validation->error_string;
        $display .= "</ul>\r";
        $display .= "</div>\r\r";

        echo $display;
    }
}
