Using isset(), there is a potential problem that escaped me until today. You can get false positives from isset on associative arrays.
$data['Modelname']['field1'] = 'some string'; isset($data['Modelname']['field1']) => true as I would expect $data['Modelname'] = 'some string'; isset($data['Modelname']['field1']) => true although I didn't think that would be the case. This is apparently because the variable being checked is a string but I expected it to be an array. Checking for a "key" on a string will always return true. I first thought my PHP install was broken but I found some comments on php.net that makes me think this is just something that has slipped me by all this time. http://www.php.net/manual/en/function.isset.php#89651 So be careful if you are checking and you are not sure you have an array or not. Sorry for the OT topic, I hope someone find it useful since we do a lot of array juggling in Cake and pinning down the cause can be a pain. Well, now you know what I did for an hour this afternoon. /Martin --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "CakePHP" group.
