Can you upload your own PDF with fillable form fields made in Acrobat P

Can you upload your own PDF with fillable form fields made in Acrobat Pro, then autopopulate in form data gathered through a WordPress site?I would be gathering personal data through online forms / questionnaires, then inserting that data into very specific state-approved PDF's. Thanks

Yes, you can upload your fillable PDF form into JotForm. Please check this related guide: https://www.jotform.com/help/548-How-Can-I-Import-My-Own-PDF-to-JotForm 

After that you can use the Prepopulate app to prepopulate data into the PDF form: https://www.jotform.com/help/71-Prepopulating-Fields-to-Your-JotForm-via-URL-Parameters
