Description

The “ims_checkout_hidden_fields” filter is used to add additional input fields to the checkout form in the checkout page (email notification).

A plugin (or theme) can modify the output with the code:

<?php add_filter( 'ims_checkout_hidden_fields', 'filter_function_name'); ?>

The hook is located in the image-store/_store/checkout.php file.

Example

// Apply filter
function add_ims_checkout_hidden_fields( $output, $ImStoreCart, $options ) {
return $output . '<input name="site" id="site" value="sitename" type="hidden" />';
}
add_filter('ims_checkout_hidden_fields', 'add_ims_checkout_hidden_fields');

Note: $output is a HTML string, $ImStoreCart is the global cart object, $options is an associative array.
