[fantomasdm]

You can implement the __serialize() method which is used to serialize the value of a field when it is being placed in an SQL query. The only thing you need to make sure is that you can tell if the value has already been encrypted so that it doesn't encrypt it twice.

e.g.

Code: Select all

function foo__serialize($value){
    if ( isAlreadyEncrypted($value) ) return $value;
    else return myEncryptionFunc($value);
}


Where the function isAlreadyEncrypted() can tell you whether a value has been encrypted already, and the myEncryptionFunc() encrypts the value.

Hi I need to serialize only for find action, so I have add this code:

Code: Select all

function cognome__serialize($value)
   {
      //echo "azione".$_REQUEST['-action']."#";
      //return $this->gcrypt($value);
      if ($_REQUEST['-action']=="edit" || $_REQUEST['-action']=="new")
         return $value;
      else
         return $this->gcrypt($value);
   }


It's seem to me that its works!!
Thanks for help and for your patience!!!!

It would be better if you could find a way to tell if the value is encrypted without relying on the current action, because there may be other actions and instances where you save the record (e.g. the update/copy record action, or other cutsom actions).
