Ciao, mi spiegate perché

codice:
if ($this->viewItems($nome_variabile)) $value = $default;
funziona e

codice:
if (isset($this->viewItems($nome_variabile))) $value = $default;
mi da il seguente errore???


Parse error: parse error, expecting `','' or `')'' in /.......orm.php on line 80

Fatal error: Unknown(): The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition makeform of the object you are trying to operate on was loaded _before_ the session was started in /......ut.php on line 70

...Il secondo errore dovrebbe essere causa del primo
