I have an HTML & CSS Landing Page where my goal is when the customer click on the button: he will populate a Data Extension and new window will open in the same tab:

<button class="button button2" style="float:right" 
name="unsub" type="hidden" value="true">Unsubscribe</button>

The AMPscript:

IF NOT EMPTY(RequestParameter("unsub")) THEN
SET @SubKey = RequestParameter("subkey")
SET @email = RequestParameter("E-mail")

The problem is that when i tried to put the HTML form action the link open, but the Data Extension not populate.

I hope your AMPscript part is correct...And only have trouble in HTML section. As I dont see full code, I have tried to simulate the demo, and the below worked fine. Please try to compare with the below and figure out.

IF NOT EMPTY(RequestParameter("unsub")) THEN
SET @SubKey = RequestParameter("subkey")
SET @email = RequestParameter("email")
UpsertData('2019DEC21_Demo',1,'SubKey',@subkey,'E-mail',@email) //change your DE Name
Redirect(concat("https://salesforce.stackexchange.com?subkey=", @SubKey))

<!DOCTYPE html>
<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
<h1 style="color:maroon; text-align:center;">SF-StackExchange Demo</h1>

<form id="myform" action="%%=RequestParameter('PAGEURL')=%%" method="post" target="_blank">
<input type="text" name="email">
<input type="text" name="subkey">
<input name="unsub" type="hidden" value="true"/>
<input type="submit" value="Unsubscribe"/>


And I also verified it Upsert the DE. enter image description here

  • Hello @Vishal. But when do you click in your button whant happens? I think i'm not clear, i want that when you click in the button, another page opens (url) and DE be populated Dec 22, 2019 at 18:06
