Question

Using the opencart image manager how would I set the upload to automatically remove: spaces and un-safe characters from the image filename?

Filemanager.php

$filename = basename(html_entity_decode($this->request->files['image']['name'], ENT_QUOTES, 'UTF-8'));

Answer 1

The best way would be to use a simple preg_replace such as

$filename = preg_replace('~[^\w\./\\\\]+~', '', $filename);

That will allow letters, numbers, underscore, back and forward slashes and a . in the filename only, and strip out anything else
