An attempt to save a form with a CCK number_decimal field with decimal separator set to "comma" and #access set to FALSE via hook_form_alter, results in a form validation error, message 'Only numbers and the decimal character (%decimal) are allowed in %field.'. The node being edited already contains a value in the field in question, which is displayed and editable properly when #access == TRUE.

Comments

When this error happens, I can see $start == '1000.00' and $value == '100000' in number_decimal_validate. When the node is saved without #access = FALSE, I see both start and value == '1000,00'.

The problem is that $element['#value'][$field_key] in number_process ends up with the default decimal separator when #access == FALSE, while it contains the user-entered decimal separator when #access == TRUE and a value was posted. The attached patch deals with this, while still keeping proper validation of the decimal separator in case of posted data.

Thx for the patch. The patch worked for me.

I had this problem without setting #access to false via hook_form_alter (but maybe because of using Content Permissions?)

Maybe someone else can review this also?

I had a look at the patch. And my brain froze for a minute.

The patch is good, but I couldn't resist rolling one that's functionally equivalent (in practice), and has some comments. (For which I took a little peek at another CCK module's 'process' function.)

Meh. That is not "functionally equivalent", in that I am filling $element['#value'][$field_key] also when it was unset.

This patch is unfortunately longer, but I think it still reads OK.

By the way: in other issues (like #283341: Illegal value in text field; field's array is being changed) I've seen references to 'drupal_execute() not working', which relate to incorrect internal values, just like this one. So it seems better to drop the explicit references to #access = FALSE, in the patch.
