Add row function at the form will not diplay properly at the pdf

I assume you are looking to match the HTML view to your PDF. Your current PDF view doesn’t match because there is only one row of text boxes.

You will need to edit your PDF and split the single row of text boxes into 2 rows of text boxes. You will then need to change out the original PDF in your CF7 form with the updated version and re-map the fields such that you have 4 mappings instead of 2.

If you don’t want to edit your PDF, you might try using mail-tag mappings with an extra blank line between the tags:
[row1tag]

[row2tag]

However, it is hard to make recommendations because it would depend on the exact contents of your PDF and CF7 forms.

Let me know if that helps or not.

and also the signature in html message in pdf is missing also,
if I input fewer data only it will appear
but if I completely input all details the signature will be missing..

There are many possible reasons why the signature isn’t working.

I think someone had an issue similar to what you describe caused by a CF7 multi-step plugin. Are you using a plugin like that?

I would like to debug your issue for you, however, I will need access to your WP instance. If you don’t mind sending me temporary login details by email to admin at maximum dot software then I will log in and try to debug your issue.
