Description
The “ims_download_filename” filter is used to modify the filename for downloadable files.
A plugin (or theme) can modify the file name with the code:
<?php add_filter( 'ims_download_filename', 'filter_function_name' ); ?>
The hook is located in the image-store/admin/download.php file.
Example
// Apply filter
function change_ims_download_filename( $filename, $image_directory, $file_type, $file_id ) {
return "image-{$file_id}". $file_type['ext'];
}
add_filter('ims_download_filename', 'change_ims_download_filename');
Note: $filename is a string, $image_directory is a string, $file_type is an array with the information about the file, $file_id is an integer.
