How to pass user input from one form to another?

There are cases in which you want to redirect users from one form to another. The two forms may contain common fields and you don’t want users to fill out the same information twice. This is where custom redirect URLs come in. Using them, you can pass information from one form to another easily.

The redirect URL can be specified in the SettingsThank You Page section, under Redirect with custom variables and provide the custom URL.

123FormBuilder custom variables

Important: Files uploaded through File Upload fields, Single/Multiple choice fields, Dropdowns, Likert Scales, Phone fields cannot be passed to another form.

Build your custom URL using the following example:

The part that is highlighted remains unchanged and it is required for the custom URL to work. Copy the following structure into a text editor:

Now, you will need to add your own information from your forms.

1. Replace 222222 (where it says form-222222) with the ID of the form where you want to redirect the user’s input. You will retrieve the ID in the URL or in the Publish – Get Link section of your form.

2. Replace 2323232 with the ID of the field where the value will be passed. In preview/view mode of your form, right-click on the input box and select Inspect Element. The ID is a set of numbers located next to “data id=”

3. Replace 1212121 with the ID of the field from which the value will be retrieved. Retrieve it the same way as in step 3, only this time you’ll need to view the form from where you retrieve the value from the input.

You can have two have separate IDs if you have a name field or address field which contains multiple subfield. In this case you need to look at the data-index . For example,  at the name field you will be having: First Name – 1234567-1, Last Name – 1234567-2. Therefore, the right syntax will be &control1234567-1=request2222222-1&control1234567-2=request3333333-2. To add the initials continue by adding &control1234567-4=request2222222-4.

Add as many parameters as you need to.
e.g. control222222=request333333&control444444=request555555


  1. Hello,

    I use both java script and iFrame to showcase your forms on my site. i was hoping that there was a way to transfer customer data from one form (if the customer choose that particular product) in an iFrame, to another form further down the web page. In a nutshell:

    Our customer will have the option to enroll in several benefits, all ala carte. If they enroll in the major medical, they will fill out a health questionnaire. The form for the health questionnaire takes every demographic from the customer that will be needed for the final complete product enrollment form. I would like to pass along the demographic information collected in the questionnaire to the final product enrollment form.

    To be clear, the customer will NOT be going from the questionnaire directly to the enrollment form. They will fill out the enrollment form after going through the website, looking at video’s, etc, for a full education of what is being offered.

    Is this possible some how? Thanks!

    1. Hello! We will need more details about your scenario. Since this is a complex request, please address your need of assistance to our Customer Care team. Get in touch with them directly from your account or from our Contact Page. They will be more than happy to assist you.

  2. I’d like to put the value of a drop-down selection straight into the redirect URL, similar to how I can output it into the HTML block with the [{xxx(###)}]. Do you provide a way to do that?

    I’d like to use that to control which ‘thank you’ page a user sees based on their selection, this would be a straightforward way to do that if I can directly request the value.

    1. Hello Shawn,
      If you want to redirect the users to a different page depending on the answers they give it is easier to use Conditional Logic for this. By going to Settings–>Rules you can redirect the users to the specific pages. If you need further support, be sure to contact us at support@123formbuilder.com

    1. Hello Chuck,

      Thank you for reaching out to us.

    1. Hello!

      Unfortunately, you cannot pass user input to your Wix store checkout page. If there’s an order form you want to create that will take form users to payments after submission, wouldn’t you want to try one of our payment gateways we are integrated with starting with our Platinum plan? We are currently integrated with 11 payment gateways, such as PayPal, PayPal Pro or Stripe. Moreover, we have many payment features: you can add coupon codes, markups and discounts to your forms. Not to mention the notifications you can create which will trigger an email to the buyer once the payment has successfully gone through.

      Here’s our payment gateways comparison page.

      To see what each plan has to offer, follow our features matrix page.

      To read more about the features we offer for order forms, consult our documentation here.

      If interested in an upgrade, have questions or need assistance, don’t hesitate to contact our Support Team at support@123formbuilder.com or via our contact form.


  7. Hi, I’m trying to make a mock-up of an online store. I’d like users to be able to be able to specify options in a form on a wix using a combination of radio buttons, drop down menus etc and then use the values that they’ve selected to add that product to the basket. No actual buying functionality is necessary, just adding to the basket and displaying these products. Is this possible using a 123 contact form?

    1. Hello!

      With the Platinum plan, you can integrate your order forms with any of the payment gateway integrations we provide (e.g. PayPal). You can add checkboxes, radio buttons and dropdowns to your online order form, assign them prices and include them in calculations which will be sent to your merchant account on submit. Have a look in our documentation tutorial regarding complex order forms for a better overview: http://wix.123formbuilder.com/docs/how-to-create-an-online-complex-order-form/

      Also, with our Payment feature, you can add a real-time payment summary to your form. This means the summary changes as the form users completes the form.

      Have a look at our payments documentation.

  9. I’m reviewing my form after building a custom URL passing variables form the first form to the second form…after submission of the first form, a message saying something like “please wait for form submission”; after several minutes of waiting, the second form still never showed up…here is the URL I built…is it possible that it is incorrect…http://wix.123formbuilder.com/sf.php?=1025535&customVars123=yes&control11025614=request8314591&control8315463=request8314592&control8314766=request8315474&contol8314594=

    1. Hello Leauretta!

      I have studied the URL you were using. It seems that you have missed the ‘s’ at sf.php?=. It’s actually sf.php?s=. Try now to add the line http://wix.123formbuilder.com/sf.php?s=1025535&customVars123=yes&control11025614=request8314591&control8315463=request8314592&control8314766=request8315474&contol8314594=
      request8315643 in the Redirect with custom variables box, from SettingsNotifications. Hope this helped!
