Hidden Field for capturing referral source

I basically want to capture the http referrer string upon user registration; using either a hidden field, or whatever. So I can use the backend of my s2member as a sort of jimmy rigged crm.

Thank you for your inquiry.

I went over this in this post:

I’m not experienced enough to take all the logic that you’ve laid out, and apply it to my example. In theory, I understand that:
1. I need to set up a url that has the variable I’m trying to capture
2. I need some way to attach those variables to a user’s profile

Now for my specific situation, I’ve found a script that takes the utmz cookie in google analytics, and parses out all the different variables (like referring domain, keyword, medium, source) , listed here:

<?php
//DEFINE COOKIE DOMAIN, ALLOWS SCRIPT TO BE USED ACROSS MULTIPLE DOMAINS
$domain = $_SERVER['SERVER_NAME'];
$domain = "." . ltrim($domain,"www.");

// SET COOKIES FROM GOOLGE-ANALYTICS COOKIE
$info = $_COOKIE['__utmz'];
// Get rid of id stuff
$holder = split("u", $info, 2);
$string = "u" . $holder[1];
// Parse String
$ga_vars = split("\|", $string);
foreach ($ga_vars as $var) {
list($key,$value) = split("=",$var);
if ($key == "utmcmd") { setcookie("Medium", $value, time()+100000000, "/", $domain); $medium = $value; }
if ($key == "utmctr") { setcookie("Keywords", $value, time()+100000000, "/", $domain); $keywords = $value; }
if ($key == "utmcsr") { setcookie("GAsource", $value, time()+100000000, "/", $domain); $gasource = $value; }
}

// SET REFERRING URL
if (!isset($_COOKIE['Referer'])) {
setcookie("Referer", $_SERVER['HTTP_REFERER'], time()+10000000, "/", $domain);
$referurl = $_SERVER['HTTP_REFERER'];
} else { $referurl = $_COOKIE['Referer']; }

// SET FORM_URL VALUE
$formurl = "http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];

// SET LANDING PAGE
if (!isset($_COOKIE['LandingPage'])) {
setcookie("LandingPage", "http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'], time()+10000000, "/", $domain);
$landingpage = "http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
} else { $landingpage = $_COOKIE['LandingPage']; }
?>

So I imagine that there is some way for me to somehow grab the variables from the code above, and display them in my user list in the admin dashboard as another column of information. But I have no idea how that would work.

1. I need to set up a url that has the variable I’m trying to capture
2. I need some way to attach those variables to a user’s profile

If you have to store this information, then this video will be of use to you:

Ok, this is my current assumption for what I need to do:

1. Create a custom hack to pull in dynamic information and store it in a custom registration field. I believe I have that one 90% figured out. I created an ‘s2hacks.php’ file, stored it under /mu-plugins/, and inserted the following code:

<?php
add_action("ws_plugin__s2member_before_custom_field_gen", "my_dynamic_field_options");
function my_dynamic_field_options ($vars = array ())
{
    $_field = &$vars["_refs"]["_field"];
    if ($_field["id"] === "lead_source")
        {
            $_field["options"] = //I have no idea what to put here. Some variable from my google parser script?
            
        }    
         
}
?>

2. I created a custom registration field, with the id of ‘lead_source’
3. I don’t know how to hide that field from the registration form yet, but I should be able to figure it out.
4. What I don’t know how to do is take the variables from my google parser script above, and feed them into the ‘lead_source’ field in my s2hacks.php file.

You could try saving the data you take from that script, and save it into the global scope, then get it in this script if you have to.
