In Sitecore WFFM(Web Form for Marketers) - Can we add hidden field at runtime - i.e. on Submit Action and assign some value to the hidden field.
I also want to reuse this value if there is an exception on the form and user resubmits the form.
Product Details - 7.2 rev. 141226 , Web Forms for Marketers 2.4 rev.140117
As the very simple, you may create hidden field like this (of course, you may provide alternative and more complex bespoke behavior for your hidden field):
public class HiddenField : SingleLineText
{
protected override void DoRender(System.Web.UI.HtmlTextWriter writer)
{
this.textbox.Parent.Parent.Visible = false;
base.DoRender(writer);
}
}
With the next step you need to register that field with WFFM. In order to do that just create an item for your new field:
/sitecore/system/Modules/Web Forms for Marketers/Settings/Field Types/Custom/Hidden Field
Within that item you specify assembly and class name for that hidden field, as is very common way to Sitecore.
So far, so good. Now you can use your hidden field as others, including adding them programmatically.
P.S. Unfortunately, I do not have an example of code for adding fields programmatically at the moment. However you can try finding that yourself with Reflector, dotPeek or any other disassembling tool. Library should be in your \bin folder already, called Sitecore.Forms.Core.dll

I'm using wagtail CMS for Django, I want to add a dynamically populated value for a dropdown and save it on the Page model, this is my code:
class MyPage(Page):
domain = CharField(max_length=10, choices=MY_CHOICES)
subdomain = CharField(max_length=10, choices=[('', '------')]
I've got some frontend logic to populate dynamically the options for subdomain, but after I hit save I got: The page could not be created due to validation errors And in the subdomain field: Select a valid choice. [my value] is not one of the available choices.
I can't use ForeignKey to populate subdomain because it depends from an external API service that we're using.
I tried to use a custom field that inherits from CharField with no success, it looks it executes validate method only for the domain field.
If you use the choices argument, you have to predefine the list of possible values. Read the relevant part of the docs (last two paragraphs of that section).
You could omit the choices argument from the model field definition and only render a HTML select tag in the frontend (which is then filled with options dynamically, like you explained).
You could also look into changing the default widget of the CharField to a select tag, like this answer and this part of the docs show.
I am trying to make a NameValueList collection editable with GlassMapper and I don't seem to be able to get to the bottom of this.
We have a list of validations that can be attached to a field and I would like to have the validation message editable in ExperienceEditor.
The collection is pre-processed when GlassMapper is retrieving the item:
Validations = glassItem.GetValidations();
#foreach(Validation validation in Model.Validations)
{
<div id="#validation.Identifier" ng-message="#validation.AngularKey" ng-cloak class="mtg-validation-msg">
#Html.Glass().Editable(validation, e => e.ErrorMessage)
</div>
}
Error that I am getting:
Failed item resolve - You cannot save a class that does not contain a property that represents the item ID. Ensure that at least one property has been marked to contain the Sitecore ID. Type: MyAssembly.Models.Validation
It is not possible to directly edit certain types of complex fields in the Experience Editor, such as Treelist, Multilist or Name Value Collection.
Instead, you should set up and use an Edit Frame. This will pop up a modal dialog allowing you to edit the field, it is not inline but means you do not need to leave the Experience Editor. This is the recommended approach to this problem.
Since you are using Glass Mapper, since version 4 you can declare Edit Frames all directly from code and now have to declare/set them up in the Core database first.
#if (Sitecore.Context.PageMode.IsExperienceEditor)
{
using (Html.Glass().BeginEditFrame(Model, "Edit", x => x.Validations))
{
<div>Edit Validations</div>
}
}

I am working on WFFM Sitecore.
I have one droplist "Title" with option of
Mr
Miss
other title
And one required text-box called Other.
The text-box is hidden on page load and it will be shown only when the user selects the other title option from droplist.
If we are selecting Mr or Miss then the Other text-box is hidden but it is still a Required field. When we submit the form it triggers the required field validation of the hidden Other text box .
How can I remove the required fields that are hidden on WFFM save action.
You will need to remove the "Required" flag from the field in the WFFM editor, and then add some custom JS validation that checks the Title field and if its set to Other Title, validate that the text box has been populated.
You can't do that in WFFM without custom JavaScript.
You would also want to make sure that your server code validates this again to protect against someone trying to bypass the JS validation.
I have followed the steps in the following link Template Settings and created custom templates for Entry, Comment and Category. To the Custom Entry Template, I have added an additional field. I have a requirement to display it in the Categories.ascx. I am able to override the Categories.ascx but I am unable to get the value of the added field using WeBlog's API. Here's the code that I am using. But the issue is that the Class EntryItem doesn't have the additional field that I have added. Is there a way to read this field using WeBlog API?
EntryItem[] blogEntries = ManagerFactory.EntryManagerInstance.GetBlogEntries();
EntryItem inherits from CustomItem I believe, so you can use the InnerItem Property to get access to the actual Item. Your field should then be available like this:
entryItem.InnerITem["YouField"];
You can use a field renderer in the Categories.ascx file to display the value of you field and use data binding to get the item assigned to the field renderer.
<sc:FieldRenderer ID="FieldRenderer1" runat="server" FieldName="YourField" item='<%# entryItem.innerItem %>'/>
In Categories.ascx you can add this code to render the new field on the front-end:
<sc:FieldRenderer FieldName="Your New Field Name" ID="frNewField" runat="server" />
Then in the C# code-behind, add this code to data bind the front-end field renderer to the entry item's underlying Sitecore item:
frNewField.Item = entryItem.InnerItem;
I have a ChoiceField where the choices are not known at the time the HTML is rendered; they are defined dynamically by the user and added to the form through Javascript, but the validation naturally fails since the selected option is not in the choices attribute (which is just an empty list). I have tried setting the field to a CharField, but then the validator just gets a string value that needs to be converted into a list before it van be used. Ah, and I'd like to avoid subclassing the field class as it's just for one occasion.
I hope this is clear. Any ideas?
Don't subclass the field class but override the clean_<yourfield> method in your Form class. See the docs here.
