- Patch #45530 by Morbus: filter_form shouldn't default to #weight 0
When a form element doesn't specify a #weight, it is assumed internally as #weight 0. However, to ensure that our form elements display visually *as they were defined in the array* we, in form_builder, count the number of elements, divide by 1000, and set that as the weight:
# Assign a decimal placeholder weight to preserve original array order
if (!isset($form[$key]['#weight'])) {
$form[$key]['#weight'] = $count/1000;
}
The above code will set the #weights of elements that have not defined a weight to something like 0 (first element in array definition), 0.001, 0.002, and so on. However, anytime a form element *explicitly* defines a #weight of 0, that #weight is kept at exactly 0, which would cause that form element to appear BEFORE the elements that didn't have a #weight defined (and thus received a #weight such as 0.002).
Consider the following pseudo example:
$form['game_title'] = array(
'#type' => 'textfield',
...
);
$form['game_description'] = array(
'#type' => 'textarea',
...
);
$form['game_format'] = filter_form(variable_get('game_format', NULL));
return $form;
Here, we're not definiing weights on our two textfields. We then add an filter_form. The second parameter of the filter_form is $weight, which defaults to 0. After this $form hits form_builder, we have weights 0 (game_title), 0.001 (game_description), and 0 (filter_form) respectively. This is then sorted by weight, which causes filter_form (the third element in the array) to appear BEFORE game_description (0 is lighter than 0.001).
The short lesson is: explicitly defining #weight 0 for a form element is probably a bad idea. This patch changes the default #weight of filter_form to NULL, instead of 0, and also removes any other explicit setting of #weight to 0 in core.
