Answer 1

You will need to create a hidden input, then use JavaScript to populate the hidden input prior to posting the form so that unsubscribe.php can retrieve it via $_POST.

Answer 2

By using the <input type="hidden" ... /> tag:

<form action='unsubscribe.php' method='get'>
<input type="hidden" name="email" value="[email protected]" />
<input type='submit' value='Unsubscribe me'>
</form>

If you are going to use <form method="get" ...> you might as well just make a url:

<a href="http://www.example.org/unsubscribe.php?email=zee%40example.org"&gt;Unsubscribe&lt;/a&gt;

Or with php (note the urlencode):

print("<a href=\"http://www.example.org/unsubscribe.php?email=".urlencode("[email protected]")."\"&gt;Unsubscribe&lt;/a&gt;");

Answer 3

Why not when composing the link for the e-mail, append the e-mail address you're sending it to in the unsubscribe url?

<a href="http://example.com/[email protected]"&gt;Unsubscribe Me!</a>
