Need to upload some files in Symfony? Excellent! You've come to the right place!

These days, uploading files can be simple... or incredibly complex - with cloud storage, private files, thumbnailing, validation and so much more. So let's tackle... all of it!

  • Understanding basic file uploading
  • File uploads in a Symfony form
  • File (and Image) validation
  • Naming files (unique vs keeping the original name... or both?)
  • Handling/moving uploaded files in an organized way
  • Rendering links to the uploaded files
  • Thumbnailing with LiipImagineBundle
  • "Uploading" files in your data fixtures
  • Flysystem: using a filesystem abstraction
  • Uploading files but keeping them private
  • Adding a download endpoint for "private" files
  • Fancy AJAX uploading with Dropzone
  • Storing files in the cloud (S3)

So get into the (Drop)zone and let us upload some serious knowledge to you in this... multipart(.../form-data) tutorial. Ok... better jokes are inside... I promise!
