Add Support for a Custom File Type in File Uploader
By default, the MainWP File Uploader Extension doesn't support all file types. By using the
mainwp_file_uploader_allowed_file_types filter, it is possible to add support for any file type. In this example, we will show how to add support for the JSON file type:
- Install and activate the MainWP Custom Dashboard extension
- Go to the PHP section (MainWP > Extensions > Custom Dashboard > PHP)
- Paste the following code snippet and Save Chagnes:
add_filter('mainwp_file_uploader_allowed_file_types', 'mycustom_mainwp_file_uploader_allowed_file_types');
function mycustom_mainwp_file_uploader_allowed_file_types( $types ) {
$types[] = 'json';
return $types;
}
