Form not submitting data

@majortom84,

Interesting, you are using...  
if( empty( $this->input->post() ) )
instead of...
if ($this->form_validation->run() == FALSE)

Any reason why?

assume that u need to show alert when validation failed
and you submit your form to the same url where you view the form (which is common way in CI):

PHP Code:

public function foo()

    {
            if($this->form_validation->run()){
            }else{
//set alert
                $this->postal->add('failed to validate!', 'error');
            }
} 


then every time you open link you will see error alert because u did not submit anything. That's why you need first check if something posted or not.
