RE: Issu form_validation - _this - 03-02-2015
Hello komang,
According to CI3 User Guide, look at Loader Class and you'll see that you can't pass two libraries as two string parameters. The class will try here to load the session class with a form_validation parameter, which is interpreted as a var that doesn't exist at all.
The good way is to chain load :
PHP Code:
$this->load->library('session')
->library('form_validation');
Or even the same array method that you used to load helpers in constructor
RE: Issu form_validation - CroNiX - 03-02-2015
Or (also in the userguide) use an array...
$this->load->library(array('session', 'form_validation'));

How to view specific error in form?
RE: Issu form_validation - Avenirer - 03-03-2015
It would be a good idea to rtfm... http://www.codeigniter.com/docs
RE: Issu form_validation - _this - 03-03-2015
@Avenirer : Agree with you, but it would be great to redirect him to the right page of userguide ^^
@komang: Here are form validation error handling
You should add the UserGuide to your bookmarks !
RE: Issu form_validation - sandeep - 03-03-2015
Hi Komang,
You can Load session library in autoload.php as well. As you have to use session in maximum pages.

RE: Issu form_validation - CroNiX - 03-04-2015
You'd also need to show us the view where you are trying to display the error messages. You also don't use xss_clean for a validation rule. More recent versions of CI removed that. See the available rules in the CI3 userguide.
