The “ims_substitutions” filter is used to modify the substitution values used in the email messages sent to customer and administrators.

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

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

The hook is located in the image-store/_inc/cart.php file.


// Apply filter
function modify_ims_substitutions( $substitutions ) {
	$substitutions[] = 'new subtitution';  
	return $substitutions; 
add_filter('ims_substitutions', 'modify_ims_substitutions');

Note:  $substitutions is an numeric array.
