This plugin embeds a Nextcloud Forms formular in a static site. It provides a mechanism for the static HTML site to embed a form and to collect and store the user data.
The form specification is loaded at build time from the Nextcloud using the public form link. The HTML form is then build according to the extracted JSON form specification.
When the submit button is pressed a simple JS function collects the form data and sends it to the Nextcloud server using the public API.
For this plugin to work a Nextcloud with the Forms App is needed.
Create a form and make it public. Copy the public link and pass it as the
link parameter to the nextcloud_forms shortcut:
{{% nextcloud_forms link="https://nextcloud_url/index.php/apps/forms/..." %}}
Success Text
{{% /nextcloud_forms %}}
The Success Text is shown after the form is successfully sent to the server.
Nextcloud Forms public API is not handling CORS requests correctly, especially the preflight checks. This leads to the XmlHTTPRequest failing with a CORS error and the browser not submitting the data.
At the moment there are two open feature requests at Nextcloud Server and Nextcloud Forms that should fix these issues:
Until these are merged into upstream, at least the changes to Nextcloud Forms have to be applied manually to the Nextcloud installation.
