How to disable an email link after first click

[deegeorge]

Hi,
I am sending a link in the email to open and enter some data.After entering the data submit it to database.
Again if the user is trying to open the linkin email, its compulsory that it cant allow the user to open that link. How to block
the email link in the second click?


Urgent,
Thanks in advance,
Deepa

1. when the data injection done in the first time set a flag in the table.

2. every time check that flag to get into that page, so in the second time that flat would be set up and it would nt allow to get that data entry page anymore then redirect to other page and sayng 'you already have added details'

Prabirchoudhury 's recommendation will work perfectly.

To do this you'll have to add a variable to the URL link (the query string) that will identify the user when the visit the page.
