Filling In WFFM Form Field When Field Title Is Translated

Question

I have a function to fill in a user's first name, last name and email address when they are logged into our web site. But, now that we have translated our pages into dozens of languages, a bug has come up. When the field name is translated from English, it is not found and the field is not populated. Other than adding each of the foreign languages to the conditional statement, is there a way to fix this bug by using the item name instead of the title?

private void FillInUserData(Control control)
{
    foreach (Control child in control.Controls)
    {
        if (child is BaseControl)
        {
            if (child is InputControl)
            {
                InputControl field = (InputControl)child;

                if (field.Title.Equals("Email Address"))
                {
                    field.Text = UserSession.EmailAddress;
                }
            }
        }
    }
}

Answer 1

If you are trying to fill the field based on the current user, why not use the rules engine instead? There are default rules available, documented here.

On your field, edit the rule. You can select condition(s) based on users (from a certain domain, or whatever you need) and add as action the "Use the default value from user profile specific field". This reads the value of the specific parameter in the user profile of the current website visitor and makes it the current field value. As this rule is set on the field, you'll have no more trouble with translations.

What condition you should use, depends on the requirements. But the "Security" section in the rules is a good starting point. You can verify if the current user is anonymous (or not), whether he is in a domain or role, ... In your case that could be a not-anonymous user in thee extranet domain.

I would create a new WFFM field in Sitecore and then you have the full control of this field and it's not hacky.

1. Backend implementation

Here is the implementation which renders the user email into a div element.

using System;
using Sitecore.Form.Core.Controls.Data;
using Sitecore.Form.Web.UI.Controls;
using Sitecore.Web.UI.HtmlControls;

namespace MyProject.WFFM.Fields
{
    public class UserDataEmailField : BaseControl
    {
        private Panel container = new Panel();

        public override ControlResult Result
        {
            get
            {
                var item = Sitecore.Context.Database.GetItem(this.FieldID);
                return new ControlResult(item.Name, Sitecore.Context.User.Profile.Email, string.Empty);
            }
        }

        protected override void OnInit(EventArgs e)
        {
            this.Controls.AddAt(0, this.container);
        }
    }
}

2. WFFM field item in Sitecore

Then you need to create the new WFFM field item in Sitecore like the following.

After you are done with this you can use this new field on your forms.

private void FillInUserData(Control control)
{
    foreach (Control child in control.Controls)
    {
        if (child is BaseControl)
        {
            if (child is InputControl)
            {
                InputControl field = (InputControl)child;

                if (((BaseControl)child).ControlName.Equals("Email Address"))
                    field.Text = UserSession.EmailAddress;
            }
        }
    }
}    

I figured this syntax out by debugging:
