EP Email Signatures

EP Email Signatures adds a signature pad to EP Email contact forms, for agreements, consent forms and anything else that needs a signature.

Overview

Sign with a finger, pen or mouse. Works on phones and tablets as well as computers.
Type your name instead. Keyboard users can switch to a typed signature, and without JavaScript the field becomes a typed-name box, so the form always works.
Checked on the server. A required signature that is empty, blank or damaged is refused with a clear message.
Kept privately. Each signature is stored as a protected image with a copy of the answers. Only administrators can see them, from this plugin’s settings screen, where View shows the signature and the answers.
In the notification email. The signature arrives as a PNG attachment, with its reference number.
A PDF copy. Add "pdf_copy": true to a form and both you and the person who signed get a PDF of the submission, answers and signatures. Administrators can download it again from the signature list.
Data requests covered. With EP GDPR, a person’s data export includes each signature they gave, and erasing them deletes their signature images and records. Copies already sent by email cannot be reached from the site.

Install EP Email first.
ep-email-signatures.zip comes with an EP Suite licence, supplied directly by ElmsPark (see EP Suite plugins); after install it updates through your site’s Updates screen.
Upload via Plugins → Manage Plugins. Activate.

Add a field to the form’s definition in EP Email:

{ "type": "signature", "name": "signature", "label": "Your signature", "required": true }

To send a PDF copy of each signed submission, add "pdf_copy": true to the form itself.

New add-on: a signature pad field for EP Email contact forms ("type": "signature"). Sign with a finger, pen or mouse; works on phones.
“Type your name instead” for keyboard users, and the whole field becomes a typed-name box when JavaScript is off.
Required signatures are checked on the server: an empty pad, a blank image or a damaged image is refused with a clear message.
Each signature is kept as a protected image with a copy of the answers. Only administrators see them, on this plugin’s settings screen (View shows the signature and the answers).
The notification email carries the signature as a PNG attachment and names its reference number.
PDF copy: add "pdf_copy": true to a form and both the owner and the visitor get a PDF of the submission (answers plus signatures). Administrators can download it again from the signature list.
Data requests cover signatures. With EP GDPR, a person’s data export includes each signature they gave (the image itself, the answers, when and from where), and erasing a person deletes their signature images and records. Copies already sent by email cannot be reached from the site.
