Hi there, I am not still your client, I need some technical informations before purchase.

I have to develop, in a WordPress site, a mechanism that allows anyone who participates in events to automatically generate a pdf with an attestation, entering their own data and a code that will be communicated during the event (which corresponds to the seminar / workshop title and to the place / institution where it was held). Obviously all and only participants can generate the certificate.

The user registers on a form with the following fields to be filled in:

- Name - Surname - Course Title - Date - Location - email: (which will not be reported on the certificate but it’s important to import it into our mailing list)

In the registration form (and / or even in the diploma area), the student will also be asked to enter a code to confirm that he has followed the course (the code is delivered on the day of the event). The best solution, if possible, is that Course Title, Date, Place will be filled in automatically depending on the code you enter (for example, code 001 = Artificial Intelligence course, Milan, September 2, 2017, code 002 = Visual Storytelling course, Turin, September 10, 2020 etc.)

Always, if possible, it may make sense to include the possibility, for each email address, to request a single code only once. Eg by name@mail.it I can use code 001 only once. But if I do another course, and they give me code 002, I can only use that only once.

Do Gravity Forms + Gravity PDF + Gravity Invitation Code plugins solve all together the issue? Thanks for your answer in advance.

No answer for this?

Hi, sorry for the delay. The current plugin would not satisfy your requirements alone. Right now, it is mainly a code verifier. You can set specific codes or codes that “contain” certain sequences to have different logic after submitting (this is via Gravity Forms by default) and then do some action that gets your results, but you will definitely need to do some extra coding and configuration on your site to get all of this done. We do plan on implementing some similar features but it may not be for a month or so.

You may be able to get a lot of this done by using conditional field logic as well though. For example… having the Course title field for ABC Course only show if the Invitation Code field contains or starts with “abc-3mf43-...”. This filed would have a default/pre-populated entry of ABC Course. Hopefully, that makes sense. Cheers!

Hi there – the plugin appears to adversely affect Gravity Forms for us by changing how the date picker fields are formatted. We were trying to work out why our fields’ selected formats (dd/mm/yyyy) weren’t working and were displaying as mm/dd/yyyy instead and causing field validation errors.

Disabling the Invitation Codes plugin fixed our problem with the date fields, but now we can’t use the Invitation Codes, obviously!

You can see screenshots of the errors:

Is this an issue you’re aware of or know a fix for?


Sorry for the delay, but we have not been able to replicate the issue. What theme are you using? Any other GF add-ons?

Actually, I think I see one issue…. it shows that you selected dd/mm/yyyy in the form editor format, but on your form entry you have mm/dd/yyyy. Can you verify that this is not the issue?

That was the problem – I am selecting the dd/mm/yyyy format in Gravity Forms, but on the front end the date picker inputs the date as mm/dd/yyyy – if I pick dd.mm.yyyy it also rewrites the date on the front end as mm/dd/yyyy.

The theme is a custom theme we’ve inherited – as it is a live site it’s difficult to test by switching it away, unfortunately. However, this is also happening in Gravity Forms preview mode – not sure if that’s making use of theme functions at all though.

Other add-ons are some of the GF perks – GP Unique ID and Gravity Forms + Custom Post Types are the two other GF related plugins currently running.

I have gotten around it a bit by changing the date selection to dropdown/select fields instead though.

Presale question: I need to be able to upload a list of pre-generated codes. Once these code have been uploaded I need one code to be shown on the confirmation page and also be emailed to the user after the form has been submitted. Each code can only be used once, so after it has been used it needs to be removed from the list.

Is this possible with this plugin?


You can bulk upload via CSV or one line per code in a text box. If a code is on the users WP account, you can use custom fields to display it on your confirmation page. Otherwise, we have a shortcode that will generate a code when a page is pulled up. However, there is no way to just show codes from the list unless it is on a users profile as a custom field. This will not remove codes automatically but as mentioned earlier, you can set codes to only be used a set number of times. You can also set expiration dates.

Just to clarify, if the user does not have a WP account, then I can still use a shortcode to generate a code on the confirmation page. I just can’t have the code removed from the list via this method.

Yes, regardless if they have an account, you can use the shortcode to automatically generate a one-time use code when the page loads.

Hi, I have a problem … if I insert one by one the code … it works … but if I enter with Add Codes per line the codes do not work … how ever

Can you specify what problem you are having… is there an error you get when trying to enter per line while using that tab? Does any error show at all? Do the codes appear to get added but not working? etc…
