I have developed a form with few fields in it. The form is working fine now and meets all my requirement, which I planned till date.
Now, I was just thinking to generate 'Reference ID' or 'Request ID' while form submission and display the following message on the page e.g. Thank you for submitting your request. Your reference ID is [Reference ID/Request ID]. Please mention this Reference ID for future correspondce.
Would need your help on how to generate this Unique Reference ID.
