Sending Multiple File Attachments from a Form Workflow

Sending several files through one form sounds simple until you account for validation, upload limits, temporary storage, mail transport size limits, and cleanup. That is why multi-file workflows deserve their own implementation plan instead of being treated like a tiny extension of a one-file form.

What a solid flow should handle

• file type and size validation before send
• temporary storage with predictable cleanup
• clear upload field naming for multiple attachments
• graceful handling when one file fails but the form itself is valid

If the project uses a drag-and-drop uploader such as Plupload or a similar helper, keep the upload step separate from the final email step whenever possible. That gives you a much more stable experience on shared hosting.
