Title: HTML Button in Email
Post by: kevin plummer on March 19, 2008, 09:34:15 PM

I want to add 2 HTML buttons to an email to accept or decline an event

Are there any examples in Nettalk on how to intercept this request and process the event?

Cheers,

Kevin

Of course adding the button in an email is not a problem, right? So what I would do is generate the email's HTML to call the procedure with a parameter. Maybe something like:

button URL to accept invitation:  http://www.yoursite.com/Invite?accept=1

button URL to reject invitation:  http://www.yoursite.com/Invite?accept=0

Then in your procedure, do something like:

  CASE SUB(p_web.wholeurl,1,8)
    OF 'accept = 1'
       ... do the accept stuff...
    OF 'accept = 0
      ... do the reject stuff...
  END !Case

Hi Kevin,

Mike is right. All you're gonna do is generate a small <form> in your Emails HTM section. The "action" for the form will be a URL of your site. Getting the URL right is important, so something like;

http://www.yoursite.com/response?accept=yes&user=lkhjfgsld8945

Obviously each email you send out has a unique "user" field whatever that is. Typically it's the unique id of the record in the database.

In your procedure, called Response, you can use p_web.GetValue('accept') and so on.

But wait, there's more.

Many email clients no longer allow a Button in an Html email. In other words this approach no longer works. You are allowed a link though, so instead of a <form> with buttons, you use a link.
