Hi I'm a newbie to Silverstripe and have limited php knowledge

I've taken over a clients website from a previous developer who had set up a custom userform with a payment facility to accept payment for event registration. This works fine with the default settings but if the client want to add a checkbox of options (e.g. how did you find out about us etc) I get a server error.

The following code I'm assuming refers to the default fields that work.

static $defaultFields = array(
array('Type'=>'Text','Title'=>'Title'),
array('Type'=>'Text','Title'=>'First Name'),
array('Type'=>'Text','Title'=>'Last Name'),
array('Type'=>'Text','Title'=>'Address1'),
array('Type'=>'Text','Title'=>'Address2'),
array('Type'=>'Text','Title'=>'City'),
array('Type'=>'Text','Title'=>'County'),
array('Type'=>'Text','Title'=>'Postcode'),
array('Type'=>'Text','Title'=>'Daytime Telephone'),
array('Type'=>'Text','Title'=>'Mobile Telephone'),
array('Type'=>'Email','Title'=>'Email Address')
);

I'm thinking if I add a Checkbox array to this it would work?

Problem is I don't know the correct syntax to add - any help would be gratefully received.

Thanks

I assume that you are referring to custom code, written by the previous developer, and not the SilverStripe User Defined Forms module? Or is it some other existing module do you think? (In which director does the code live)

it's hard to tell what's going on based on this bit of code and no real error information, it probably depends on how your developer has implemented this.

First of all you might try to temporary place your site into dev mode. Place this line of code to the bottom of your /mysite/_config.php file (don't forget to remove or set to 'live' later):

Director::set_environment_type("dev");

Then we would probably need the whole code, unless it is an existing module...

Hi martimiz

Yes I was referring to the custom code which the previous developer has customised from the Userforms module.

I added the line of code you supplied and below is the error that was thrown up.

I think what is happening is the previous developer has written the code just to include a specific array of fields as per below. But now the client wants to add the Editable Multiple Options field which is not include in the array in the custom code so therefore it is throwing up the server error!

[User Error] Please implement getFormField() on EditableMultipleOptionField
GET /get-involved/events/starwalk-2015/register-now/

I don't know in what way exactly your your developer adapted the UserForms module, but normally you would define your formfields from within the CMS, and the only options you have for a a multi-option field is either:

- Checkbox group (EditableCheckboxGroupField)
- Dropdown field (EditableDropdownField)

It looks like your client is trying to create a EditableMultipleOptionField. This is not actually a formfield, but should be seen as an abstract class, and it is used as a base (parent) class for multi-option fields like the two above. If you try to use it as a FormField on its own, it will give the rather cryptical error 'Please implement getFormField() on EditableMultipleOptionField'. So I'd suggest using one of the two above.

I cannot quite understand though, how your client is able to construct an EditableMultipleOptionField like that. Are they not using the Form settings from within the CMS? (EDIT: probably not, concidering the array you posted :))

That did the trick - thanks!
Don't know why the other options are showing in the CMS or why the client chose to use that rather than the checkbox!
