5. Uploads - Phlo

5: Uploads

The image and file field types handle uploads end to end: storage, tokenised URLs and, for images, thumbnails.

5.1: The image field

cover:  field (type: 'image', title: 'Cover', list: false)
avatar: field (type: 'image', title: 'Avatar', list: false)

An image field stores two columns: the filename (cover) and a token (cover_token). On upload it writes the original and a scaled thumbnail, and renders the thumbnail in the record view linking to the full image. The file field is the same without the image processing.

5.2: Where files go

The app entrypoint declares the storage roots:

files:  dirname(__DIR__).'/data/uploads/files/',
images: dirname(__DIR__).'/data/uploads/images/',
thumbs: dirname(__DIR__).'/data/uploads/thumbs/',

Files are served back through a tokenised route, so URLs are not guessable from the row id. Keep data/uploads/ out of git.

5.3: Schema columns

When you hand-write the table (as the SQLite demo does), remember an image field is two columns:

cover TEXT, cover_token TEXT

The demo's seed.phlo creates exactly these columns alongside the relation columns.
