Deleting Files

Hey Ad F.!

Try this ;)

$entityManager->transactional(function(EntityManagerInterface $entityManager) use ($uploaderHelper, $reference) {
    $entityManager->remove($reference);
    $entityManager->flush();

    $uploaderHelper->deleteFile($reference->getFilePath());
});

If removing from the database fails, deleteFile will never be called. If deleteFile fails, the database transaction is rolled back.

Cheers!

Hey Cybernet2u,

But we add "Delete" button for every file, so if you want to delete multiple files - you just need to press a few "Delete" buttons, right? Or do you want to do it in a single request? Then I'm not sure about your UI, how users will choose what files to delete in a single request? Do you have any ideas? :)

Cheers!

long story short, when i delete a category, i wan't to delete every file from each blog post :)

Hey Cybernet2u,

Ah, I see :) So, what's is your problem? It depends on how much blog posts in your categories are, but you just need to fetch all the blog posts in the category you're about to delete and iterate over each post, and actually remove it. It might be a performance issue if you have a lot of posts.. well, in this case I'd recommend to look into direction of Messenger component to create a queue of deleted blog posts and handle them async. We've already released the course about Messenger component in full, see it here: https://symfonycasts.com/sc...

I hope this helps!

Cheers!

Hey Octavio,

Sorry for the late response! Unfortunately, we don't have bandwidth to help our users with personal projects. But I will try to give you some hints at least. It sounds like you just need to drop that delete button for the uploaded files, then use will still be able to add new images but will not be able to delete them.

I hope that helps!

Cheers!

Hey!

In that case what you need to do is to make an API call to AWS S3 to check if the file indeed exists. This link may give you an idea of how to make the API call: https://stackoverflow.com/a...

Hey Ad F.

I don't fully understand your problem. In your example you are passing the file path of a Blog image and that's exactly what you want to do, isn't it?

the only way would be to store fullPath, right ?

yes, thats what i want, but i'm unable to check if $files is null because even if there is no image uploaded ( imageFilename is null ), it will return Uploader::BLOG_IMAGE

does it make sense now ?

Ahh I get it but if you get the ArticleReferences from an Article object, all of its references files should exist, unless it's a new reference but you can check if such object has an ID already set. Well, besided that, what you can do is a file existence check using the Filesystem, or you can add a little bit more of code to ArticleReference::getFilepath() method so you can check if it has something set on its $filename property, if it's not, then return null.

I hope it makes any sense to you :p
Cheers!

anyway, i will add some code to check only if getImageFilename is null or not
all i was trying to say, is that this tutorial always presumes that the author of an Article will always upload an Image

Ohh, yea, sometimes is better to skip some edge cases when you are trying to teach something but that's why we have comments :)

Cheers!

if an Article doesn't have any uploaded files ( or imageFilename is null ) getImagePath ( actual name from tutorial still returns something - UploaderHelper::ARTICLE_IMAGE )
