-The `erroridf` function evaluates the format string, then prints the result to the ERROR log and fails the build. Unlike the [`errorf`] function, you may suppress errors logged by the `erroridf` function by adding the message ID to the `ignoreErrors` array in your site configuration.
-
-This template code:
-
-```go-html-template
-{{ erroridf "error-42" "You should consider fixing this." }}
-```
-
-Produces this console log:
-
-```text
-ERROR You should consider fixing this.
-You can suppress this error by adding the following to your site configuration:
-ignoreErrors = ['error-42']
-```
-
-To suppress this message:
-
-{{< code-toggle file=hugo >}}
-ignoreErrors = ["error-42"]
-{{< /code-toggle >}}
