Changing checkboxes options during hook_node_validate
I have a node form that contains a checkboxes field with options NULL at the time the form is displayed. During node_validate, if certain criteria is met, an array of options (checkboxes) is created, and the form needs to be redisplayed with the checkboxes as part of it. I've tried setting #options = the new array in the $form, in $form_state[original_form], etc all to no avail. The field doesn't change. I also set one checkbox in the field at the start, so that I could find it in the $form and $form_state structures, changed where I found it to the new options array, and again, no change. I am setting $form_state[rebuild] to true, and even tried explicitly calling for the form to be rebuilt. -- --- drupal.org/user/367108 linkedin.com/in/jeffrgreenberg accidentalcoder.com / ayendesigns.com @accidentalcoder
One thing that is either part of the issue, or a separate issue that impacts this, is that the checkboxes field is added via hook_form_alter. I notice that although the field appears in $form_state[values] it does not appear in $form_state[field], so I'm wondering where $form_state gets the information for the field when rebuilding the form.

The checkboxes have to be added in the form creation stage, so in either hook_form or hook_form_alter. Then in the hook_validate, set a variable on $form_state['storage'] and set $form_state['rebuild'] = TRUE; and check in your hook_form or hook_form_alter for your $form_state['storage'] setting, and if set then add your checkboxes. I suggest looking at the form_example_wizard in the examples module, as that's basically what you are after, even though it's not a typical multi-step wizard you are after, the logic is still the same.

Ok, I've tried that. The last thing I do in hook_node_validate is $form_state['rebuild'] = true; What I notice is that hook_form_node_form_alter does not fire between then and the form being redisplayed, so my pulling the options from $form_state['storage'] never happens.

Actually you should be able to alter the form in the validation function yes? Just change the function signature to pass $form by reference and make the changes to the form that you need rather than going through the later hook?

Tried this. So my function signature is: function si_core_node_validate($node, &$form, &$form_state) { and the last thing I do is: $form['refs'][LANGUAGE_NONE][0]['#options'] = $options; $form_state['rebuild'] = TRUE; form_set_error('refs', 'Select the potential entity links to be processed.'); yet the form displays the original field option.

Actually you never really know what is going to happen in validation. So many modules can do funky things. A lot of times the multi-step type forms handle the rebuild through a submit callback. There's another option here as well, depending upon the criteria that has to be met, and that is using the #states system. You can see an example here: http://cgit.drupalcode.org/examples/tree/form_example/form_example_states.in... Jamie Holly http://hollyit.net On 2/11/2015 11:58 AM, Metzler, David wrote:

Got it to work after all using the method of storing the new options in $form_state[storage] and then, if it isset during the subsequent hook, force-feeding the field with the values from the form state. Thanks very much Dave and Jamie!! On Wed, Feb 11, 2015 at 2:25 PM, Jamie Holly <hovercrafter@earthlink.net> wrote:

There could be something else overriding that in validation. Instead of using the default hook_node_validate, trying adding $form['#validate'][] = 'my_custom_validation_function' in hook_form or hook_form_alter. That way it's the last validation hook called.

Ok, did that , and the #validate function is firing. I might get this wrong, because my confusion level is high, but here is what I think I observe in xdebug. When I was setting a form error during validation, when it eventual made its way to drupal_process_form it wasn't doing a rebuild because of that. So I tried not setting a form error, since I'm setting $form_state[rebuild]=true anyway. Now drupal_process_form does a rebuild, but what happens is that just prior to the rebuild, the #options are what I just set them to with $form[my_field][LANGUAGE_NONE][0][#options] = my_options_array; in validation, but right after the rebuild, the original value is back. Do I need to set #options in more than one section of $form or somewhere in $form_state? On Wed, Feb 11, 2015 at 12:01 PM, Jamie Holly <hovercrafter@earthlink.net> wrote:

One thing that is either part of the issue, or a separate issue that impacts this, is that the checkboxes field is added via hook_form_alter. I notice that although the field appears in $form_state[values] it does not appear in $form_state[field], so I'm wondering where $form_state gets the information for the field when rebuilding the form.

I have a node form that contains a checkboxes field with options NULL at the time the form is displayed.
During node_validate, if certain criteria is met, an array of options (checkboxes) is created, and the form needs to be redisplayed with the checkboxes as part of it.
I've tried setting #options = the new array in the $form, in $form_state[original_form], etc all to no avail. The field doesn't change.
I also set one checkbox in the field at the start, so that I could find it in the $form and $form_state structures, changed where I found it to the new options array, and again, no change. I am setting $form_state[rebuild] to true, and even tried explicitly calling for the form to be rebuilt.

Also make sure your hook_form_alter has & signs in front of the $form parameter (as well as $form_state) to indicate pass by reference. It’s easy to overlook that if your field isn’t changing when you think you should. If you forget to do this hook_form_alter won’t actually alter anything, but it won’t give you any errors either. mymodule_hook_form_FORMID_alter(&$form, &$form_state); From: support-bounces@drupal.org [mailto:support-bounces@drupal.org] On Behalf Of Jeff Greenberg Sent: Wednesday, February 11, 2015 7:43 AM To: support@drupal.org Subject: Re: [support] Changing checkboxes options during hook_node_validate One thing that is either part of the issue, or a separate issue that impacts this, is that the checkboxes field is added via hook_form_alter.
