Checksum Expiration
February 03, 2011, 05:45:39 pm
We're going to find out tomorrow, but I'm curious if anyone knows what this means regarding checksums:

"The way it works is you create a "special" link in the CiviMail message that includes the checksum token {contact.checksum}. When people click on the special link, it looks them up in the database and prefills any information on the contribution form or profile with any data that exists in their record. The special link lasts for seven days from the time it was sent out."

We sent out a mailing to all members regarding renewing their membership with a link to a membership renewal contribution page using a checksum. It's worked great thus far. If that checksum expires after seven days, what will someone experience if they click on the link in the email AFTER the checksum has expired?

The system won't know who they are so will treat them as Anonymous and no fields will be pre-filled

And so how does one change this default behavior, to, say, one month?

I couldn't find anyway to do this without hacking the code.

It appears you can set the default in the file by modifying the generateChecksum function CRM/Contact/BAO/Contact/Utils.php. Change the line:

Code: [Select]
$live = 24 * 7
to

Code: [Select]
$live = 24 * 30
to make it 30 days.

I thought I'd add the word expire and expiry to this post to help people find it :)

I have created an issue for this. I'm getting tired of hacking this file after every upgrade.

This config option ended up at civicrm/admin/setting/misc?reset=1 in CiviCRM from v4.1.0

Look under "Administer => System Settings => Undelete, Logging and ReCAPTCHA".
