Hjælp til at poste dato i mysql

har du prøvet med nogen feltnavne?

$query = "insert into $this->dbUserTable (id, eventname, eventdate, eventdesc) values (NULL, \"$this->eventName\", \"$this->eventDay - $this->eventMonth - $this->eventYear\", \"$this->eventDescript\")";

edit:
ellers prøv at put det i en var føst.
$v1 = $this->eventName;
$v2 = $this->eventDay . " - " . $this->eventMonth . " - " . $this->eventYear;
$v3 = $this->eventDescript;

$query = "insert into $this->dbUserTable values (NULL, '$v1', '$v2', '$v3')";

$query = "insert into $this->dbUserTable (eventID, eventName, eventDate, eventDescript) values (NULL, \"$this->eventName\", \"$this->eventDay\" \"-\" \"$this->eventMonth\" \"-\" \"$this->eventYear\", \"$this->eventDescript\")";

Det var lige det der skulle til. Jeg takker mange gange for hjælpen.
