It is hard to determine what the problem is without much information. There may be a few issues:
1. The fields that are missing are just named differently from what you expect
2. The fields are not actually fields but black boxes in the PDF that look like fields
3. The field types are not supported (such as file attachment fields and signature fields)
4. The PDF is corrupted
Are you able to share your PDF? You can send it to my email which is admin at maximum dot software if you like. Otherwise, please share more information about your PDF, such as screenshots, missing field properties, etc.
The PDF is a sales tax exemption form from the state of Michigan.
You can find it here.
Ideally we would want a customer to fill out the form and hit “Submit” and have the form emailed to our accounting department.
I think your issue was that you didn’t get how the plugin works.
The WPForms fields are treated as a separate list of fields from the list of fields that are in the PDF form. The field mapper tool allows you to connect the WPForms fields to the PDF form fields. The mapping settings are stored and managed separately from WPForms field settings.
The plugin does allow you to automatically create WPForms fields and map them to yet unmapped PDF fields. This is allowed to make it easier for you to quickly put a web form together without manually creating WPForms fields, which may take a long time if your form is long. However, once WPForms fields are all created, you can adjust the WPForms fields in any way you like while the field mappings would be unaffected. If you delete a field mapping, that doesn’t delete the associated WPForms field.
I hope that helps.
