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.
