I have pre-existing node authored by each user. However, for presentation purposes, I use a Webform to collect data from the user.

Existing Node: Assessment

  • field_question1
  • field_question2
  • field_question3

Webform

  • field_question1
  • field_question2
  • field_question3

On submit, I would like to compare "the user submitting the Webform" with the author of existing nodes, then set the field values of the submitter's existing node with the new values from the submitted webform.

This worked well in Drupal 7, but in Drupal 8 I don't seem to understand the syntax, nor do I see a place to set up or pass variables.

Can this be done in the current state of Drupal 8 Rules?

  • It looked to me like the module was ready and usable if you could do it with code, but the UI was in need of polish and documentation. However, after 3 days and no one seeming to hint that they knew of a way to do this, I am just going to mark it answered. Thank you for your time kiamlaluno and pierre.

Can this be done in the current state of Drupal 8 Rules?

To my knowledge the answer to your question is No (it's part of what this is all about).

If you're in for getting a better understanding about all this, then have a look at these links:

Here's a simple Rule that will react on a webform submission and create a new node of type "Article" with the article title set to the submission time to show how webform submission values may be used to set node values. This Rule assumes you have the default webform type "Contact" enabled.

Use the Rules 8.x-3.x-dev version and you can import this Rule and try it out for yourself.

  • I see my answer is really a response to the answer from @Andrew Wasson, rather than a response to the original post. But it does serve to demonstrate how Rules can be used with Webform. I'll update my answer with information about using an existing node, like the original poster asked.

  • Sorry for taking the subject off topic but your resulting post is interesting all the same. I've struggled with Rules for Drupal 8 and have found it much less hassle to build custom handlers like the one I described in my post. That could be because I adopted Drupal 8 when it first landed nearly 5 years ago and Rules is still in a state of development. Your YML is obviously worth looking into. Thanks for that.

As far as I know, Rules can't create a node on a webform submission.

A better approach is to create a custom web form handler to produce the node for you. I submitted the recipe to do so in the following posting: How to create a node out of a webform submission?

  • Of course Rules can create a node on webform submission. Complete example below.

  • Actually, this isn't even what the original poster was asking - the question was about an existing node and setting values in that existing node from a webform submission.

  • Thanks @anonymous. You're right. I didn't see that they were appending to existing nodes. My answer doesn't help in that regard.
