There are two Exact Target examples that I would like to implement in a landing page together. The first examples involves the Web Collect demo found here:


The "Subscribe-Unsubscribe_Multiple_Lists.txt" file in that download is a simple Web Collect form that adds a new subscriber to lists that they check off. I insert my member id as well as the list ids in the appropriate spots and it works great. The problem is, if a subscriber already exists in my database, this form will return an error and not update their desired lists.

That is where this example comes in:


I would like to insert the php script found above to update that subscriber when they hit submit instead of returning a "Subscriber Already Exists" error.

Is this the best route to go for this? Has anyone done something similar?

Thank you!


I would recommend using the SubAction to Add and Update instead of just "sub". Below should give you this functionality and avoid the error you are seeing.

<input type="radio" name="SubAction" value="sub_add_update" checked> 

Let me know how that works out for you. Thanks!

    Are you getting the same error message? Are you trying to update the All Subscribers list or just individual lists? – Jeremy Aug 26 '14 at 20:27
  • Individual. If I use that value for the sub button, I get the "an error has occurred while attempting to save ur subscriber info" error. This is different than before – nickruggiero Aug 26 '14 at 20:35

    I just tested this out in my own account and got it to work a few different times. I subscribed initially, updated my subscriber, unsubscribed, and then re-subscribed without any issues. @user3087325 If you're still having issues, can you open up a support case with ExactTarget - help@exacttarget.com – Jeremy Aug 27 '14 at 3:57
  • I made a stupid mistakes, an this works perfectly! Thank you – nickruggiero Aug 27 '14 at 19:59
