InfoPath Dev

 I have a form with a button to add more data. When the user presses the button, the entry is submitted a new form opens. I want some of the fields in the new form to contain the same information entered in the previous form. Is there a way to do this using rules or a function in InfoPath?

 

Thank you in advance. 

With code, you could use input parameters, but I also wonder - what if you just query the library for the forms submitted by the same user, and then pre-populate with the most recent data? You could sort the returned data by created date... maybe have a button in the form to let the user choose to pre-populate the data, and then you wouldn't need code?

 Can you elaborate more on what that code would look like? Do you have an example? How would I start? Where could I research this topic more?

If you mean setting a default instead of using a rule, you could start w/ what you are already using - just in the field's properties, set a default value. https://support.office.com/en-us/article/set-the-default-values-for-a-form-d1ffca72-fd68-4775-af6d-7d998df536b2 has more on that.

Yes but how would I set a default value based on past input that has already been submitted? This value is subject to change but we want it prepopulated in the new form if the user clicks the add more button.

I'm so sorry, I had this thread confused with another - no wonder my last reply made no sense! Here's a blog post on using input parameters: https://blogs.msdn.microsoft.com/infopath/2007/02/26/passing-data-into-a-form-input-parameters/ - if code isn't an option (like if this is Office 365, or your SharePoint admins don't allow browser forms with code) my other thought would be promoting all the fields with data you need and then on opening a new form, run a query in the form load rules for the last form for that user in the library, and use rules to populate values.
