Nunjucks
Nunjucks macro options

Use options to customise the appearance, content and behaviour of a component when using a macro, for example, changing the text.

Some options are required for the macro to work; these are marked as "Required" in the option description.

If you're using Nunjucks macros in production with "html" options, or ones ending with "html", you must sanitise the HTML to protect against cross-site scripting exploits.

When to use this component

You should only ask users to upload something if it’s critical to the delivery of your service.

How it works

There are 2 ways to use the file upload component. You can use HTML or, if you’re using Nunjucks or the GOV.UK Prototype Kit, you can use the Nunjucks macro.

Make sure errors follow the guidance in error message and have specific error messages for specific error states.

If no file has been selected

Say ‘Select a [whatever they need to select]’.
For example, ‘Select a report’.

If the file is the wrong file type

Say ‘The selected file must be a [list of file types]’.
For example, ‘The selected file must be a CSV or ODS’ or ‘The selected file must be a JPG, BMP, PNG, TIF or PDF’.

If the file is too big

Say ‘The selected file must be smaller than [largest file size]’.
For example, ‘The selected file must be smaller than 2MB’.

If the file is empty

Say ‘The selected file is empty’.

If the file contains a virus

Say ‘The selected file contains a virus’.

If the file is password protected

Say ‘The selected file is password protected’.

If there was a problem and the file was not uploaded

Say ‘The selected file could not be uploaded – try again’.

If there is a limit on how many files the user can select

Say ‘You can only select up to [highest number] files at the same time’.
For example, ‘You can only select up to 10 files at the same time’.

If the file is not in a template that must be used or the template has been changed

Say ‘The selected file must use the template’.
