Issue status update for http://drupal.org/node/18663 Project: Drupal Version: cvs Component: base system Category: bug reports Priority: critical Assigned to: chx Reported by: killes@www.drop.org Updated by: chx Status: patch Dries? chx Previous comments: ------------------------------------------------------------------------ March 10, 2005 - 02:51 : killes@www.drop.org If you select nothing from a set of checkboxes an empty string is save to the variables table. This is a problem if the calling code assumes, it would get an array. We should make it save an empty array. The problem is the form_hidden field that we add. even if we replace form_hidden($name, 0) by form_hidden($name, array()) it isn't going to work, because the empty array is eaten by htmlspecialchars. redLED found this bug and he does not like it: 02:53 < redLED> i just like things saying 'CRITICAL' in red 02:53 < redLED> it gives this warm impending doom feeling 02:53 < redLED> and is generally associated with nuclear reactors in people's subconsciousness Suggestions welcome. ------------------------------------------------------------------------ March 12, 2005 - 19:47 : Steven There is no way to fix it in form_checkboxes() itself afaik, because even without htmlspecialchars, it would still come out as "Array". You can only create arrays indirectly through form submissions, by naming your values "foo[]". But you can not create empty arrays this way. So it is really up to the module which uses form_checkboxes() to handle this. A simple is_array() should do the trick. ------------------------------------------------------------------------ March 28, 2005 - 17:27 : chx Attachment: http://drupal.org/files/issues/checkboxes.patch (1.71 KB) system_settings_save can not really cope with this situation. This makes a problem with empty node options. And the fact that we have a check everywhere we use form_checkboxes is error prone, too. Here is a patch. If this accepted I'll comb the core for dead code. For eg. the first three lines of taxonomy_save_vocabulary and so. ------------------------------------------------------------------------ March 28, 2005 - 17:32 : chx Attachment: http://drupal.org/files/issues/checkboxes_0.patch (1.71 KB) Oh NO! One strayed space! I fixed it before steven beheads me.... ------------------------------------------------------------------------ March 28, 2005 - 18:36 : chx Attachment: http://drupal.org/files/issues/checkboxes_1.patch (1.64 KB) Among other changes, I have moved the hidden field form_checkboxes[] out of $edit. I have included HTML code, yes, but this is a very special thing, so it does not merit changing form_input just 'cos of this. And you won't need to theme a hidden field... ------------------------------------------------------------------------ April 8, 2005 - 08:19 : chx Attachment: http://drupal.org/files/issues/form_checkboxes_2.patch (1.9 KB) killes did not like the previous version.
