Remove image when delete block about nova-editor-js

[rik43]

+1 @lorado
without nova, i used this code:

    private function deleteNotUsedImages($newBlocks, $oldBlocks)
    {
        $images = [];

        // previous images list
        foreach ($oldBlocks as $block) {
            if ($block['type'] === 'image') {
                $url = $block['data']['file']['url'];
                $images[$url] = 1;
            }
        }
        // exlude existed in new version
        foreach ($newBlocks as $block) {
            if ($block['type'] === 'image') {
                $url = $block['data']['file']['url'];
                unset($images[$url]);
            }
        }
        // drop files
        foreach ($images as $image => $temp) {
            $file = public_path($image);
            if (is_file($file)) unlink($file);
        }
    }

Thanks @Krato !

I do like the idea, however it doesn't looks like the Editor JS API can help with this as it currently stands. Raised an issue hoping they can build a configurable endpoint - i rather this be in the core then me hacking on some listeners.

I've deployed a new version which gives you the ability to specify the path and disk - please let me know if you come across any issues with this.

Hi @advoor,

I just thought about possible implementations... How about this idea:
Before updated content is stored in DB, determine, if there are some image blocks in old version of content, that do not exist in the new version. Then parse file path from url (and all thumbnails) and remove these files.
Actually may be simply collect all the images in old content, then remove items from this list that are used in the new content. Images that are left should be then removed from disk.

It should work

This is my next focus when I get some time (Y)
