Description
The “ims_checkout_order_fields” filter is used to add additional fields to the checkout form in the checkout page.
A plugin (or theme) can modify the output with the code:
<?php add_filter( 'ims_checkout_order_fields', 'filter_function_name'); ?>
The hook is located in the image-store/_store/checkout.php file.
Example
// Apply filter
function add_ims_checkout_order_fields( $output, $ImStoreCart, $options ) {
return $output . '<input name="site" id="site" value="sitename" type="text" />';
}
add_filter('ims_checkout_order_fields', 'add_ims_checkout_order_fields');
Note: $output is a HTML string, $ImStoreCart is the global cart object, $options is an associative array.
