Only posting comment if condition is met

[Eddie]

Hey peter,
I have a question , if I wanted to only post the comment on the return value of a script
for example if the script returns a non-zero value post the comment.
I am new to github actions so there might be something I am not doing properly

I am trying to assign the return value of the script to an environment variable
and then checking that in the if statement of your example code.

  - name: Find Comment
    uses: peter-evans/find-comment@v2
    id: fc
    with:
      issue-number: ${{ github.event.pull_request.number }}
      comment-author: 'github-actions[bot]'
      body-includes: This comment was written by a bot!

  - name: Create comment
    if: steps.fc.outputs.comment-id == '' && env.failedNum != 0
    uses: peter-evans/create-or-update-comment@v2
    with:
      issue-number: ${{ github.event.pull_request.number }}
      body: |
        This comment was written by a bot!

  - name: Update comment
    if: steps.fc.outputs.comment-id != '' && env.failedNum != 0
    uses: peter-evans/create-or-update-comment@v2
    with:
      comment-id: ${{ steps.fc.outputs.comment-id }}
      body: |
        This comment has been updated!

Hi @EdwinFairchild

I've never seen env. variables used in expressions like that before. Does that work? Perhaps it's a new feature that I don't know about. Or maybe that's not possible, which is why it's not working. 😄

You could try using step outputs instead of env. variables. There should be plenty of examples of doing this in GitHub's own documentation.

yeah i have no clue what I was doing here. I fixed my issue though, thanks.
