i would like to validate form with validator class

senzacionale · October 2012

I am using

$this->load->library('validator'); class and

$this->validator->add_rule('first_name', 'required', 'Please enter in an first name', $this->input->post('first_name'));
$this->validator->add_rule('last_name', 'required', 'Please enter in an last name', $this->input->post('last_name'));

if ($this->validator->validate())
{
// valid
} else {
// unvalid
}

if is unvalid i woud like to show errors like "Please enter in an first name" and "Please enter in an last name". How to print this error on the front end view? I am not using form builders...

Thank you

There are a couple validate functions you can use to help with that in the validator_helper. There is a display_errors() function which will output an unordered list of errors and a get_errors() function you can use which will return an array of errors.

thank you for replay. Can i use this two functions on the view? becouse i get error that functions does not exist on view. I want to show errors on the view not controller.

Thank you

Sure. Just be sure to load the validator helpers for the view. You can do that in the controller or even the view itself:


// from view
$CI =& get_instance();
$CI->load->helper('validator');

Howdy, Stranger!
