Hello Arturwagnerowsk!
Unfortunately, you cannot use a hidden field to add a sequential number; however, you can use email notifications and/or success messages. Simply add the short code [nf_sub_seq_num] to your form submission and you will have a sequential submission number.
Here is a link to ninja forms documentation page on this short code: http://docs.ninjaforms.com/article/247-sequential-form-id-number-nfsubseqnum
Please let me know if this answered your question, or if you have any others!
Thanks!
Kenny
Hello klhall1987
I use Ninjaforms so , I want to display the seq_num in a pdf template. How can I do?
I hope yor help.
Thanks.
@gabrielgonzalesle, you need to post your own topic per the forum’s rules.
@gabrielgonzalesle, I agree with klhall1987 as you can exercise this option, but it must be in the form of a shortcode.
