What is Softr?

Softr lets you build powerful applications that connect to databases like Airtable, but sometimes you could use the help of more powerful form applications that allow things like:

​
Embed in list details block

Embedding a Fillout form in a Softr list details block lets you define different embedded forms for different records you’re displaying.
If you aren’t using a list details block, skip ahead to custom code block.
1

Create a list details block

In Softr, choose a List Details block template.

Important: You should publish your Fillout form before trying it in Softr.

Paste the embed snippet into a new field in Airtable, and display it

Create a new field in Airtable, which will contain the embedding snippets from Fillout. Paste your snippet (optionally customized) into that field. You can use a formula field, or simply a long text field.

Good to know: If you’re using a formula as the link to your Fillout form, you can pass in parameters to the form from Airtable. More details at the end of this article.

Advanced: Filtering records and access the logged in Softr user

Watch Dan Leeman from Automation Helpers build a filtered Fillout form, embedded in Softr.

​
Update forms

You can embed complex forms that allow logged in users to update their profile. For example, a form that opens in a pop-up, to allow a logged in student to update their courses. Update forms The styling of your embed can be adjusted to match your brand in Softr.

Access the logged in Softr user in Fillout forms

​
For custom code blocks

You can use the following code snippet: 
<!-- PASTE YOUR EMBED CODE HERE -->

<script>
    document.querySelectorAll("[data-fillout-id]:not([data-fillout-id=\"\"])").forEach((target) => {
    	if(window.logged_in_user && window.logged_in_user.softr_user_email) {
    		target.setAttribute("data-email", window.logged_in_user.softr_user_email);
    		target.setAttribute("data-name", window.logged_in_user.softr_user_full_name);
    		target.setAttribute("data-id", window.logged_in_user.airtable_record_id);
    	}
    });
</script>
<script src="https://server.fillout.com/embed/v1/"></script>
Right below the line to Paste your embed code here, you can paste in the embed code you copied from Fillout’s Share page for your form. That’s it!
Make sure to remove the first line in the code block, when pasting in your embed snippet (we’ve moved it over to later in the snippet, above).
You may also prefer using a simple custom embedding method as opposed to our built-in embedding snippets. Here’s an example snippet for passing in the email, full name, and record ID of the user that is logged in, using a custom iframe embedding method (if you need more customization): 
<div id="fillout_embed_div"></div>
<script>
	let filloutUrl = 'https://forms.fillout.com/t/XXXXX?';

	if(window['logged_in_user'] && window['logged_in_user']['softr_user_email']) {
		filloutUrl = filloutUrl + 'email=' + window['logged_in_user']['softr_user_email'];
		filloutUrl = filloutUrl + '&name=' + window['logged_in_user']['softr_user_full_name'];
		filloutUrl = filloutUrl + '&id=' + window['logged_in_user']['airtable_record_id'];
	}

  var targetDiv = document.getElementById('fillout_embed_div');
  var iframe = document.createElement('iframe');

  iframe.setAttribute('src', filloutUrl);
  iframe.setAttribute('width', '100%');
  iframe.setAttribute('height', '900px');
  iframe.setAttribute('frameborder', '0');
  iframe.setAttribute('marginheight', '0');
  iframe.setAttribute('marginwidth', '0');
  iframe.setAttribute('title', 'Fillout form');
  iframe.setAttribute('allowfullscreen', 'true');

  targetDiv.appendChild(iframe);
</script>
In this snippet, replace the XXXXX with the unique ending of your form URL that you can find in the Share tab of your form.

​
For list details blocks

As mentioned above, if you used a formula field to insert your embedding snippet, you can pass in information into the embed as described here.
For list details blocks
Remember to wrap the values you’re passing into the embedding snippet in quotation marks.

​
Access the URL parameters/hidden fields in Fillout

You can access the email, name, and ID URL parameters much like any other URL parameters in Fillout if using the above methods to pass those in from Softr. Click here for more information.
Your URL parameters aren’t required to be called email, name, nor ID. You can rename these in Fillout when registered, but the snippets above will need to be adjusted to replace the names with your desired names.
Fillout forms also automatically inherit URL parameters from your Softr pages. If you have any page that has a recordID URL parameter, as long as you have that registered as a URL parameter in your Fillout form, it will automatically get passed in!

Pick from linked records

Let respondents select linked records.

Embed parameters

Pass URL parameters to your embeds to track data.
