Usage

The module will prefill all webform form elements as soon as it is enabled.

Use CSS classes for excluding/including parts of your forms.

You can use the classes .webform-prefill-exclude and .webform-prefill-include to blacklist or whitelist parts of your forms. By default the whole form is whitelisted.

You can use a weform component’s wrapper classes to exclude or include components easily.

Use URL fragments to add values to the prefill store

You can add prefill values to the store by adding a special URL fragment to your links. For example:

1. You enter the page the page using the URL https://example.com#p:name=Alice.
2. Later in this session you navigate to a webform.
3. The webform contains a textfield component with the form key name which is prefilled with the value “Alice”.

You can still use fragments for something else by separating the prefill part (p:…) using from the rest of the fragment using a semi-colon ;. That means if you enter the website using https://example.com?#anchor;p:name=Alice the prefill value is removed from the URL after the JavaScript is done and you see the page as if you had entered https://example.com?#anchor instead.
