I have a client that has almost 300 PDF and Word Files. They want to use merge fields and allow the end user to answer some questions and then be presented with some documents or a document that fits their answer. For example a document that will let them dispute some inaccurate info on their credit report. The document would be pre-filled with info that the user already provided (account number, date, description of item to be disputed). Are there any wordpress plugins that can do this? Are there any wordpress plugins that deal with merge fields at all?
