Phalcon BeforeSave在保存之前没有收到数据？

Question

Before I save my model, I would like to check if $ CONT_CEDULA meets the requirements. If not, then don't save. But when saving, it is as if the variable $ CONT_CEDULA hasn't got any data. I want to know if I'm doing well or need some other event or function. Also, the echo outputs no data.

beforeSave method

public function beforeSave() {

        echo $this->$CONT_CEDULA;
        switch (strlen($this->$CONT_CEDULA)) {
        case 10:
            return validarCI($this->$CONT_CEDULA);
            break;
        case 13:
            return validarRUC($this->$CONT_CEDULA);
            break;
        default:
           echo "Numero de caracteres invalidos"  ;
            return FALSE;
    }

Answer 1

By default Phalcon wont output any data you "echo" in your controllers or your models. The easy 'workaround' is to die('your output');

If you return a value in a switch, it is unnecessary to add a break; to the end of your case.

public function beforeSave() 
{
    // check the content of $this->$CONT_CEDULA
    var_dump($this->$CONT_CEDULA);
    die;

    switch (strlen($this->$CONT_CEDULA)) {
       case 10:
          return validarCI($this->$CONT_CEDULA);
       case 13:
          return validarRUC($this->$CONT_CEDULA);
       default:
         // an example to test if your code enters this case.
         die("Numero de caracteres invalidos");
         return FALSE;
   }
}
