How to insert a random number into the email?

Hello, I have a form that sends and email with the data to the administrator and a "Thank you" email to the sender.

I am not saving anything into any database.

I just need to insert a random number/string within both emails so that the administrator will get something like this:
"A new user filled the form. His ID is 123abc"

and the sender will receive something like this:
"Thanks for your registration. Your registration number is 123abc"

I don't need a duplicate-number-check because the chance they will be the same would be very low.

The amount of number can be 6 or 10 or 12 or whatever. I have searched quite some time within the form but I did not find anything.

Thanks.

Hi dave18,

You can use a Custom Code action with a few lines of PHP to generate a random string - you can find plenty of examples with Google e.g. this StackOverFlow answer.

PS If you were saving to a database table I have a Unique ID [GH] action that will do the work for you.

Hey Bob, mind sharing your action?😀

Hi Zyraj,

In v6 you can use {uuid:} or {rand:}

Hi Zyraj,

Which version of ChronoForms are you using? My action is for CFv5 only.

Hi, Max.

{uuid:} or {rand:} may be used to store a Real UniqueID into database?

Which one is better?

And how long is the string returned?

(CF6)

Hi indiana71,

I think that both of these will return quite long random strings - the uuid in CFv5 is 64 characters. And while they will almost certainly be unique there is no check for that.

If you want a short user friendly string then you can generate that in a custom action and check that it has not already been used.
