NEWBIE Question on form submission

[oaktree8]

I have a pretty basic form,  it captures name and email and it stores the email in a input field dd_email.

 

The form action is similar to below

 

 

<form id="downloadform" name="form" class="cmxform" method="post" action="http://my.url.com/download-confirmation">

 

I want it to be like this but I can't get it to work:

 

<form id="downloadform" name="form" class="cmxform" method="post" action="http://my.url.com/download-confirmation?utm_custom=$_POST['dd_mail']">

 

 

Is there a way to reference the email address submitted on the form as part of a UTM variable on the form action?  If not how else can I do this so when it goes to the download-confirmation page it has that utm string?

 

thanks

You could use a GET action to put the form contents into the URL.

 

Or, after processing the POST request you could redirect to the page with the email in the URL.

 

Or, you could forget about the URL and simply process the POST request.
