The situation
Printed textiles, signs, business cards: the customer supplies the artwork. So far by mail, with the subject "attached" and no order reference.
Uploading artwork
Personalised goods need a file from the customer. The email route works until somebody sends a 40 MB file.
The job
Where the built-in tools stop
A contact form without an upload forces a change of medium. And a mail address as a collection point has neither a size limit nor a folder structure.
This is what the form looks like
The allowed extensions land as a filter in the file dialog - so the wrong thing cannot even be picked.
What matters here
Extensions and size on the field
Two options per upload field: which extensions are allowed and how large the file may be. The browser's file dialog then only offers what fits.
Two uploads, two purposes
One field for the print file, one for a preview image. The image upload field takes image formats, the file field takes print formats too.
One folder for everything
Which folder of the media manager the uploads land in is set in the plugin configuration. That means the same permissions and cleanup routes as for any other media in the shop.
Where it sits
Product assignment on the articles that get printed - directly visible, not collapsed. Whoever has to supply a file should see the field.
What comes back
The submission names the file, the file itself sits in the media. Print run and job type stand next to it as columns of their own.
