Date and GUID in e-mail

Dear forum
​
In previous CF versions, it was possible to add a custom code into the submit action, that sent the date of submission and could be included in the confirmation e-mail as {date}, or rather {data:date} by using this PHP:
​

<?php$form->data['date'] = date('d-m-Y H:s');?>

When I try to add the date to the e-mail content, it doesn't appear anymore.
​
Secondly, there used to be a GU id creator module, through which one could also create and include a genuinely unique ID, say, for billing purposes.

I have failed to either implement or find answers on how to do either of these two things in CFv6.
​
Many thanks for any help

{date:format}

​
For example
​

{date:d-m-Y H:s}

​
Look at the FAQs and the manual.
​
For a uuid, use

{uuid:}

Hello healyhatman,
​
I did both these things but all the variable codes do are displaying date/UUID in the form or on the message page (when placed as submit action). My question was how to get this data into an e-mail? The handbook and FAQ don't present the answer to this.
​
Thanks for your reply!

Easy if you know it. I was following the 'old' logic of customizing, 1. creating AND 2. including in the email, guess this works, too. I'll find out...
​
Thanks again!

One more question, though: I've decided to use {rand:} rather than {uuid:} (a bit too long).
​
Is there way to set min and max or number of digits? There is a nice php manual online about the different date formats and wondered if there's sth like that for random numbers as well. I've tried (for 3 digits):
​

{rand:000,999}, {rand:(100,999) }, {rand:$100,$999}, {rand(100,999):} - as well as {mt_rand:}

The curly bracket shortcodes are only for specific things you can't just put any PHP function name in there.
​
I don't think there's a way to do what you want without using a PHP block.

Alrighty, thanks anyway!
