What It Does

This plugin adds a new field type to the Contact Form 7 plugin and allows users to add a handwritten signature to the message via a signature pad.

The plugin uses Szymon Nowak's great Javascript library. Version 4 is out, with a major technical refactoring of the plugin. If you are a theme developer, please review the FAQ to see what changed, especially if you were using the provided javascript functions.

It is also now possible to use Base64 encoded inline images at your own risk because of mail clients compatibility issues. This plugin requires version 4.6 or higher of the Contact Form 7 plugin. The signature pad should work on almost every modern web and mobile browser.

Please read the FAQ for details on how to set up your signature fields. You can ask for support here. This plugin is just sharing the result of something I needed once for a project, and there is nothing commercial in there.

FAQ

First things first : verify that your email is sent in HTML format. In CF7, theres’s a checkbox at the bottom of each mail configuration to do that.

Then verify that the image is wrapped in an HTML image tag in your mail configuration, like this :

<img src="[your-signature-field]"/>

When building your signature field with CF7’s field generator, you have several options you can add to the field shortcode :

Width and height :

[signature signature-666 333x222]

Will tell the plugin to draw the field 333px wide and 222px tall.

ID and class :

[signature signature-666 id:foo class:bar]

Use CSS like you would do for any other field in your form.
For example, using the field wrapper, you can add a border like this :

.wpcf7-form-control-signature-body canvas{
border: 1px dotted #BADA55;
}
`

It depends on your form layout but once again, you can do this by using basic CSS instructions. The plugin will deal with window size and device orientation automatically updating itself to match the right size.

The only thing you have to do is override width and/or height styles to the field wrapper, not the canvas, like this :

@media screen and (max-width: 768px) {
.wpcf7-form-control-signature-wrap {
width:100% !important;
}
}
…
`

There are options for that in the field settings (only hex color supported for the moment) :

[signature signature-666 background:#333333 color:#FFFFFF]

The signature field needs to be “reloaded” too when its container’s size changes, but you should be aware that it will also clear its content. I assume this is your responsability to do so. The plugin provides a jQuery function that you can call from your theme’s script file :

window.onresize = function(){
$(‘div.wpcf7 > form’).wpcf7ResizeSignatures();
};
`

Sure, by using the signature pad’s available options directly like this:

[signature signature-666 dotSize:1.2 minWidth:1 maxWidth:5 throttle:0 velocityFilterWeight:0.1]

The main thing that changed is the way you can interact with the plugin. There’s now a jQuery plugin for that, and i got rid of all the old JS functions like sigFieldsResize and sigFieldsClear.

Available methods are now :

$('div.wpcf7 > form').wpcf7ResizeSignatures(); to resize fields $('div.wpcf7 > form').wpcf7ClearSignatures(); to clear fields $('div.wpcf7 > form').wpcf7InitSignatures(); to reload fields

So you only have to replace the former functions by these new ones. Don’t forget to have a look at your contact form additional settings tab, where there’s usually some code to clear the fields on submit.
