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