Support us
Requirements
Laravel pad signature requires PHP 8.0, 8.1, 8.2 or 8.3 and Laravel 8, 9, 10 or 11.
Installation
You can install the package via composer:
Publish the config and the migration files and migrate the database
Publish the .js assets:
This will copy the package assets inside the public/vendor/sign-pad/
folder.
Configuration
In the published config file config/sign-pad.php
you'll be able to configure many important aspects of the package,
like the route name where users will be redirected after signing the document or where do you want to store the signed documents.
You can customize the disk and route to store signatures and documents.
Notice that the redirect_route_name will receive the parameter $uuid
with the uuid of the signature model in the database.
Preparing your model
Add the RequiresSignature
trait and implement the CanBeSigned
class to the model you would like.
If you want to generate PDF documents with the signature, you should implement the ShouldGenerateSignatureDocument
class . Define your document template with the getSignatureDocumentTemplate
method.
A $model
object will be automatically injected into the Blade template, so you will be able to access all the needed properties of the model.
Usage
At this point, all you need is to create the form with the sign pad canvas in your template. For the route of the form, you have to call the method getSignatureRoute() from the instance of the model you prepared before:
Retrieving signatures
You can retrieve your model signature using the Eloquent relation $myModel->signature
. After that,
you can use:
getSignatureImagePath()
returns the signature image path.getSignatureImageAbsolutePath()
returns the signature image absolute path.getSignedDocumentPath()
returns the generated PDF document path.getSignedDocumentAbsolutePath()
returns the generated PDF document absolute path.
Deleting signatures
You can delete your model signature using
deleteSignature()
method in the model.
Customizing the component
From the same template, you can change the look of the component by passing some properties:
- border-color (hex) to change the border color of the canvas
- pad-classes and button-classes (strings) indicates which classes will have the sign area or the submit & clear buttons
- clear-name and submit-name (strings) allows you to modify de default "Submit" and "Clear" values of the buttons.
- disabled-without-signature (boolean) indicates if the submit button should be disabled when the user has not signed yet.
An example with an app using Tailwind would be:
Certifying the PDFs
To certify your signature with TCPDF, you will have to create your own SSL certificate with OpenSSL. Otherwise you can find the TCPDF demo certificate here : TCPDF Demo Certificate
To create your own certificate use this command :
More information in the TCPDF documentation
After generating the certificate, you'll have to change the value of the variable certify_documents
in the config/sign-pad.php
file and set it to true.
When the variable certify_documents
is set to true, the package will search the file allocated in the certificate_file
path to sign the documents. Feel free to modify the location or the name of certificate file by changing its value.
Inside the same config/sign-pad.php
we encourage you to fill all the fields of the array certificate_info
to be more specific with the certificate.
Finally, you can change the certificate type by modifying the value of the variable cert_type
(by default 2). You can find more information about certificates types at TCPDF setSignature reference.
