Updating existing subscribers

Question

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:

help.exacttarget.com/Global/WebCollectCodeSamplesS4/WebCollectCodeSamples.zip

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!

Answer 1

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!
