form validation and error count

[eluser]theprodigy[/eluser]
What's the easiest way to get the number of errors while using form_validation?

I would like to display how many errors the user has, in addition to listing them ("You have the following X errors:").

Thanks

I think the best way is to extend the Form validation library.
download the attached file and unzip it in the application/libraries folder, then you should be able to call the function:

Code:

$this->form_validation->error_count();

(I haven't tried this, but i guess it would be something similar at least)

or just copy paste the following to a php file called MY_Form_validation.php to the same location.

Code:

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class MY_Form_validation extends CI_Form_validation {

    function MY_Form_validation()
    {
        parent::CI_Form_validation();
    }

    /**
     * Error Count
     *
     * Returns the the number of errors
     *
     * @access    public
     * @return    int
     */    
    function error_count()
    {
        return count($_error_array);
    }
}
// END Form Validation Class Extention

/* End of file MY_Form_validation.php */
/* Location: ./system/application/libraries/MY_Form_validation.php */

actually i think it must be:

Code:

return count($this->_error_array);
