In the custom registration field area, I am trying to add a drop down so when they register they will see the current S1 and S2 User names in the drop down. These are for referral fee purposes but I cannot figure out how to have the system pull the user names. Can anyone tell me the best way to do this? Thanks!

I'm sorry, it probably is very obvious but I'm not understanding the question well. What are the S1 and S2 usernames?

Custom Registration Fields ( a developer how-to )

How to set option values dynamically,
and how to set a default selected option value too.

Create this directory and file:
/wp-content/mu-plugins/s2-hacks.php

Code: Select all

<?php
/*
Setting options dynamically for Custom Registration Fields.
*/
add_action ("ws_plugin__s2member_before_custom_field_gen", "my_dynamic_field_options");
function my_dynamic_field_options ($vars = array ())
    {
        $_field = &$vars["__refs"]["_field"]; /* By "reference". */
        /* See: http://www.php.net/manual/en/language.references.spot.php. */
        /**/
        if ($_field["id"] === "country_code")
            {
                $_field["options"] = "US|United States|default" . "\n";
                $_field["options"] .= "CA|Canada" . "\n";
                $_field["options"] .= "VI|Virgin Islands (U.S.)";
            }
    }
/*
Setting a default value for Custom Registration Fields.
*/
add_action ("ws_plugin__s2member_before_custom_field_gen", "my_dynamic_field_values");
function my_dynamic_field_values ($vars = array ())
    {
        $references = &$vars["__refs"]; /* Array of variable "references". */
        $_field = &$vars["__refs"]["_field"]; /* By "reference". */
        /* See: http://www.php.net/manual/en/language.references.spot.php. */
        /**/
        if ($_field["id"] === "country_code")
            {
                if (empty ($references["_submission"]) && empty ($references["_value"]))
                    /* If a form was not just submitted. And, there is no default value. */
                    
                    $references["_value"] = "CA"; /* Set the default value. */
            }
    }
?>

I'm also attaching a video tutorial on this topic,
where I explain how this code works in great detail.

Thank you for the tutorial. This should be a big help.

It sounds like you *might* have leading or trailing white-space characters in your hacks file. This may have happened when you copied from the forum. I'm attaching a zip file with the proper syntax. Please let us know if you continue to have trouble in this regard.

Ops...sorry, you' re right, Thanks
