Hidden field and passing URL variables

[wiggst3r]

Hi

 

I've written a site that I want to be able to track where users who visit my site have come from when they submit the form.

 

The URL is http://www.example.com?source=email_1

 

What I want to do, is If anyone has this in the URL and they submit the form, the email_1 is passed and inserted into the database

 

Thanks

$from = isset ( $_GET['source'] ) ? mysql_real_escape_string ( $_GET['source'] ) : '';

// insert here... (just an example...)

$sql = "INSERT INTO some_table VALUES ( '', 'value_from_form_one', '" . $from . "' );";
