Attaching Multiple Images to an eForm Submission

Multiple file attachments in eForm are possible, but the form and mail-processing layer both need to be structured for repeated files instead of a single upload field.

eForm can handle file uploads, but attaching several images to one outgoing email requires a slightly different design than a single-file field. The front end must accept multiple uploads, and the mail-processing logic must iterate over all validated files.

What to plan

input naming for multiple files
file validation and allowed types
where temporary uploads are stored
how the mail handler appends each attachment

Recommendation

Do not bolt multiple uploads onto a single-file workflow blindly. Treat it as a dedicated attachment flow so the validation, storage, and cleanup remain predictable.
