Using Hidden Fields with embedded forms

Want to use Hidden Fields to pass information to a typeform embedded on your site? No problem! This article will go over how to use Hidden Fields in typeforms embedded in a website or email. (If you want to dynamically pass Hidden Fields to a typeform based on a changing website URL, check out this article.)

Hidden Fields in a website embed

1. When you use Hidden Fields, they're included automatically in your form embed code. Once you've added them when creating your form, click on the Share panel.

Create multiple embed codes with different Hidden Fields

You can create multiple embed codes with different Hidden Fields data for the same form. Let's say you want to track the source—which page on your website people complete your typeform on. You can create an embed code with the Hidden Field data 'homepage' as the source for the homepage on your website. Then create a new embed code with the Hidden Field data 'about' for the about page on your website. 

1. After you've created your first embed code with your Hidden Fields (instructions from the previous section), click on Embed in a webpage and then click New embed.

2. Click Advanced and toggle the Set custom values switch.

3. Change the Hidden Field data to the new data you want to track for this new embed code.

5. Click Start embedding to save and generate a new embed code.

Add Hidden Field attributes to your embed code (for advanced users)

Creating multiple embed codes might not be the best solution for you, for example, if you want to use several Hidden Fields to pass user information. In this case, if you're comfortable editing your embed code, you can add your Hidden Field attributes directly to the embed code.

1. Select Embed in a web page and click Start embedding to generate your embed code.

Embed_start_advanced.png

2. Click Copy to grab the embed code.

Screenshot 2023-10-27 at 12.08.00.png

The embed code snippet looks something like this:

<div data-tf-live="01HCZ4DNW8JM6PEGNTQWF2PW87"></div>
<script src="//embed.typeform.com/next/embed.js"></script>

3. Configure the desired Hidden Fields by adding the data-tf-hidden attribute to the code:

<div data-tf-live="01HCZ4DNW8JM6PEGNTQWF2PW87" data-tf-hidden="email=john@doe.com,name=John"></div>
<script src="//embed.typeform.com/next/embed.js"></script>

The Hidden Field attributes follow the name: value structure in the code, and each Hidden Field is separated by a comma.

Warning! If your embed code already has some Hidden Fields configured, they will be overwritten by the ones added using the data-tf-hidden attribute.

This approach works for any data-tf attribute described in our Embed SDK documentation

Hidden Fields in an email embed

Make sure that your form’s first question is one of the following types: Multiple Choice, Picture Choice, Opinion Scale, Net Promoter Score®, Rating, Ranking, Matrix, Dropdown, Yes/No, Short Text, Long Text, Number, Phone Number, Email, Website, or Statement.

Additionally, your form should not include a Welcome Screen, or you won’t be able to embed the form in an email.

1. To add Hidden Fields to your form, click the Logic tab, choose Personalize with data, and select Hidden Fields

2. In our example, we’ll select the email and name Hidden Fields to add them to our form. You can create your own Hidden Fields by clicking Add new field. When you’ve added all the Hidden Fields you need, click Save.

3. Next, go to the Share panel.

4. Hit Publish so the Hidden Fields get added to your form link.

5. Click Embed in an email. Remember that this feature is only available for email distribution tools with a code editor like Mailchimp, and currently does not work on everyday email services like Gmail or Outlook.

6. You'll see the Hidden Fields you've added. To add the information you want to include, replace the xxxxx next to each Hidden Field with the text you want in the right-hand panel.

In our example, we're using Mailchimp to send our email so we'll add Mailchimp merge tags to our Hidden Fields. For more information on using Hidden Fields with Mailchimp, check out our guide on automatically populating Hidden Fields with Mailchimp

7. Click Start embedding.

Click_start_embedding.png

8. Click Copy to add the code to your clipboard. This code already includes the Hidden Fields you added. You can now paste the code into your email distribution tool.

Change Hidden Field values in email embeds based on answers (for advanced users)

Typeforms embedded in emails often start with Opinion Scale or Multiple Choice questions, like the email shown here:

statichf5.png

Once a respondent clicks on one of the options, the rest of the typeform opens in another tab.

Let’s say you want to display different Hidden Field values for each option the respondent chooses. For example, if your first question is an Opinion Scale question like the one shown above, and you have a Hidden Field called “user_group”, you might want to show respondents who answer “3”, “5”, or “10” a different value for “user_group” on the rest of the typeform.

You can set this up with a small amount of coding (have a tech-savvy friend nearby, just in case - our team, unfortunately, can’t provide troubleshooting for custom code). Remember that email embedding is only possible in email marketing tools with a code editor, like Mailchimp.

1. In the email embed code, you’ll find lines of code for each option in your Opinion Scale, Multiple Choice, Picture Choice, or Yes/No question, like the ones below. Each line has a Hidden Field called “user_group” with a blank value:

  • Opinion Scale:
<a href="https://form.typeform.com/to/ABCDEF?typeform-medium=embed-email#user_group=xxxxx&amp;answers-8a5053a8-b338-4cf1-8282-b105f2f7a0ae=1"
  • Multiple Choice/Picture Choice:
<a href="https://form.typeform.com/to/ABCDEF?typeform-medium=embed-email#user_group=xxxxx&amp;answers-66884627-c23a-4a43-9d27-6fdcd20cb6cd=3c1c7ccb-3b5c-4ee7-b1b3-b8e60f8ae69e”
  • Yes/No:
<a href=“https://form.typeform.com/to/ABCDEF?typeform-medium=embed-email#user_group=xxxxx&amp;answers-2319cdbb-9fcd-4368-b6b0-6c462504c08c=2319cdbb-9fcd-4368-b6b0-6c462504c08c-yes”

There will be one line of code for each level in your question. For Yes/No questions, there are 2 levels, indicated by “yes” or “no” at the end of the URL. For Opinion Scale questions, you can easily check the level by looking at the digit(s) at the end of the URL. The line of code shown above, for example, corresponds to the answer “1” on the Opinion Scale.

2. For each level, add Hidden Field attributes replacing the “xxxxx” string(s) in the URL. For example, if you have a Hidden Field called “user_group”, one level in your Opinion Scale might have a URL that looks like this:

<a href="https://form.typeform.com/to/ABCDEF?typeform-medium=embed-email#user_group=detractors&amp;answers-8a5053a8-b338-4cf1-8282-b105f2f7a0ae=1”

Now, just add the same attribute to each level’s URL.
