Melbourne Meetup August 2009 @Em Space
Start:
2009-08-11 18:00 - 21:00 Australia/Melbourne This meetup will happen on Tuesday 11th August from 6:00pm, at the Em Space offices at 289 Flinders Lane.
Pizza and beer/softdrink. Plates and napkins! And more chairs hopefully will be here on time, I'd like to handle 30 people easily, last week we had 20. Catering paid by Em Space - it worked out pretty well last week with an optional $5 donation, we'll do that again. Was the ratio of food to people good?
This is going to be about Forms. I'll be presenting on Drupal 6 form coding, how to do a multistep form, how to add validate/submit handlers. We'll look at Drupal 7 form changes. Also there is a GUI form builder, I think by Nate/quicksketch.
Look forward to seeing you all there.

#access to hide form elements
A tip that came up was setting #access to false to hide an element of a form. Quite handy to know, I think it went something like:
$form['my_bit']['this_is_serious_mum'] = array('#type' => 'select',
'#default_value' => 3,
'#options' => array(1 => 'Blah', 2 => 'Yay', 3 => 'Fooby'),
'#access' => 0,
);
