Validation
#1

Hi in ci3 i have this for validation :

PHP Code:
        $this->form_validation->set_rules('email','Email',"required|trim|min_length[0]|max_length[100]|valid_email|is_unique[users.email]",array('min_length'=>'Lunghezza minima Email 0 caratteri''max_length'=>'Lunghezza massima Email 100 caratteri','required'=>'Email obbligatorio','valid_email'=>'Inserisci una mail valida '));
        $this->form_validation->set_rules('promemoria_votazione','Promemoria votazione',"required|trim|min_length[0]|max_length[1]",array('min_length'=>'Lunghezza minima Promemoria votazione 0 caratteri''max_length'=>'Lunghezza massima Promemoria votazione 1 caratteri','required'=>'Promemoria votazione obbligatorio'));
        $this->form_validation->set_rules('risultati','Risultati',"required|trim|min_length[0]|max_length[1]",array('min_length'=>'Lunghezza minima Risultati 0 caratteri''max_length'=>'Lunghezza massima Risultati 1 caratteri','required'=>'Risultati obbligatorio')); 


Than i have an if ...

PHP Code:
        if($this->form_validation->run()){ 


in ci 4 i see instead :

$this->form_validation->set_rules i must use  $validation->setRule ( before [font=Raleway, Helvetica, Arial, sans-serif][font=SFMono-Regular, Menlo, Monaco, Consolas,]$validation =  \Config\Services::validation(); )[/font][/font]

and  instead of  [font=Monaco, Consolas, Courier, monospace]this->form_validation->run()  i must use $validation->run()[/font]


[font=Monaco, Consolas, Courier, monospace]how can i set my own error message ?[/font]

Because you are redirecting, killing your data.
PHP Code:
if($validation->run())
      {

          
redirect()->to('user/pannello_user');

      } 

I think you can use withInput() but then you need to use the old() function as well or use the form_helper for everything.
https://codeigniter.com/user_guide/gener...l#redirect
https://codeigniter.com/user_guide/gener...s.html#old

Take a look at the tutorial.
https://codeigniter.com/user_guide/tutorial/index.html
PHP Code:
public function create()
{
    
$model = new NewsModel();

    if (
$this->request->getMethod() === 'post' && $this->validate([
            
'title' => 'required|min_length[3]|max_length[255]',
            
'body'  => 'required'
        
]))
    {
        
$model->save([
            
'title' => $this->request->getPost('title'),
            
'slug'  => url_title($this->request->getPost('title'), '-'TRUE),
            
'body'  => $this->request->getPost('body'),
        ]);

        echo 
view('news/success');

    }
    else
    {
        echo 
view('templates/header', ['title' => 'Create a news item']);
        echo 
view('news/create');
        echo 
view('templates/footer');
    }

Sorry about that, missed the part where it said you didn't post any data.

Should be:
PHP Code:
if($validation->withRequest($this->request)->run()) { 
https://codeigniter.com/user_guide/libra...ithrequest

Or you need to manually input an $data array:
PHP Code:
if($validation->run($data)) { 

Where $data have been grabbed from the POST.
PHP Code:
$data = [
    
'email' => $this->request->getPost('email'),
    
'password' => $this->request->getPost('password'),
];
