It seems to work OK for me. I typically use your altered format or the
form that Bastien posted (except I usually default the parameters to
null rather than an empty string) though.
<?php
function addEvent($values = Array('name' => '', 'venue' => '',
'description' => '', 'errors' => Array()))
{
// code here displays the form
print_r($values);
}
addEvent();
?>

Array
(
[name] =>
[venue] =>
[description] =>
[errors] => Array
(
)
)
