The Signature Add-On for Gravity Forms allows you to capture signatures online by allowing users to sign your forms using touchscreen devices, touch pads or mouse by adding a new field to the Advanced Fields toolbox in the Form Editor: Signature.

Quickly and easily integrate signature capabilities into your forms without the end user having to install any special browser plugins.

With the Gravity Forms Signature Add-On you can provide a very simple user interface for allowing users to sign your forms online. It captures signature information as it is drawn and sends data to your web server where this information is converted into a PNG image and stored on your server. This happens on-the-fly as soon as the user signs the field canvas.

The Signature Add-On works on all major desktop and mobile browsers. This includes IE, FireFox, Safari, Chrome, Opera, iOS, Android, Blackberry, and WebOS.

System Requirements

  • Gravity Forms v1.6.2+
  • WordPress v3.3+
  • PHP 5.0+ with GD library support.

The Gravity Forms Signature Add-On requires your web server’s PHP configuration to have the GD library installed and working properly. The GD library is used to create the signature image file on the server.

Install The Signature Add-On

The easiest way to install the Signature Add-On is from within your WordPress site itself. If you have properly configured your Gravity Forms license key on the Settings page of Gravity Forms you should have access to the built in Add-On manager.

  • Login to your WordPress admin dashboard.
  • Go to Add-Ons under the Forms navigation.
  • Install and Activate the Signature Add-On.
  • Get Started!

If you would like to install the Signature Add-On manually, or have trouble accessing the Add-On manager, you can follow the instructions below:

  • Download the add-on plugin from the Add-Ons download page.
  • Login to your WordPress admin dashboard.
  • Go to Add New under the Plugins navigation.
  • Choose Upload from the Install Plugins sub-navigation.
  • Upload, Install and Activate the Signature Add-On.
  • Get Started!

Setup The Signature Add-On

Setting up the Gravity Forms Signature Add-On is easy. Once you have installed and activated the plugin, you’re done!

Using The Signature Add-On

After installing the Signature Add-On you will see a new field type added to the Advanced Field toolbox in the Form Editor when creating or editing a Gravity Form.

  • Go to New Form under the Forms navigation or choose an existing form from Edit Forms in your WordPress admin dashboard.
  • Add a Signature Field to your form from the Advanced Field toolbox.
  • Edit this new Signature Field and configure the field options to your liking.
  • Save your form.
  • Capture signatures!

When you view the Entry Details for a Form Entry that contains a Signature Field you will see the signature included in the entry details. The signature will be presented as a thumbnail image and you can click on the thumbnail to see the full size version of the signature itself.

For security reasons it is not automatically included as part of the {all_fields} merge tag output. You can include signatures in your email notifications by inserting the merge tag for your Signature Field in the message of your notification.

How Does It Work?

The Gravity Forms Signature Add-On is powered by the well established signature capture software SuperSignature. The SuperSignature technology and source code has been licensed by rocketgenius, inc. for redistribution as an official Gravity Forms Add-On.
