Signature Field Is Not Recognized As Being Filled
Introduction
When working with electronic signatures in webforms, it's essential to ensure that the signature field is recognized as being filled and saved correctly. However, in some cases, the signature field may not be recognized, leading to errors and frustration. In this article, we'll explore the common issues and solutions to resolve the problem of a signature field not being recognized as being filled.
Understanding the Issue
The issue at hand is that the signature field, which is a JavaScript canvas, is not being recognized as filled, and its contents are not being saved after submitting the form. This results in a standard webform error message, indicating that the field was left blank. The problem persists even after trying various configurations, including hiding the Signer Name and Signer Title fields, testing on different browsers (Chrome and Firefox), and placing the component at the top level or inside a fieldset.
Technical Details
The webform is running on PHP 8.2.26, and the site is being developed locally on a laptop without HTTPS enabled. This may raise concerns about security implications, but it's essential to note that there are no JavaScript errors in the console. The issue is specific to the signature field and is not related to any other components or configurations.
Troubleshooting Steps
To troubleshoot the issue, we'll go through the following steps:
1. Clearing Caches
Before fully testing, ensure that all caches are cleared. This is a crucial step, as cached data can sometimes interfere with the functionality of the signature field.
2. Component Configuration
Review the component configuration to ensure that it's set up correctly. Check the following:
- Signature Field: Verify that the signature field is enabled and configured correctly.
- Signer Name and Signer Title Fields: Ensure that these fields are not hidden or disabled.
- Component Placement: Check that the component is placed at the correct level (top level or inside a fieldset).
3. Browser Testing
Test the webform on different browsers, including Chrome and Firefox, to rule out any browser-specific issues.
4. Page Breaks
Test the webform on both the first and last pages using page breaks to ensure that the issue is not related to the page layout.
5. JavaScript Errors
Check the console for any JavaScript errors related to the signature field. If there are no errors, proceed to the next step.
6. Version Comparison
Compare the current version of the signature pad library with the version specified in the Drupal module. If the issue is resolved by switching back to the specified version, it may indicate a compatibility issue with the current version.
Solution
After troubleshooting and testing, the solution to the problem is to switch back to the version specified in the Drupal module, which is:
https://cdn.jsdelivr.net/npm/signature_pad@2.3.2/dist/signature_pad.min.js
This version has been tested and proven to work correctly, resolving the issue of the signature field not being recognized as being filled.
