 ### Displaying form input errors
 
-You can validate form inputs before submission using [native HTML form validation attributes](https://developer.mozilla.org/en-US/docs/Learn/Forms/Form_validation#using_built-in_form_validation) like `required`, `type="email"`, and `pattern`. For more complex `input` validation on the backend, you can use the provided [`isInputError()`](/en/reference/api-reference/#isinputerror) utility function.

 To retrieve input errors, use the `isInputError()` utility to check whether an error was caused by invalid input. Input errors contain a `fields` object with messages for each input name that failed to validate. You can use these messages to prompt your user to correct their submission.

 ### Defining custom slugs
 
-When using `type: 'content'`, every content entry generates a URL-friendly `slug` property from its [file `id`](/en/reference/api-reference/#id). The slug is used to query the entry directly from your collection. It is also useful when creating new pages and URLs from your content.

 You can override an entry's generated slug by adding your own `slug` property to the file frontmatter. This is similar to the "permalink" feature of other web frameworks. `"slug"` is a special, reserved property name that is not allowed in your custom collection `schema` and will not appear in your entry's `data` property.
