Components

File upload

This guidance is for government teams that build online services. To find information and services for the public, go to GOV.UK.

Help users select and upload a file.

<div class="govuk-form-group">
  <label class="govuk-label" for="file-upload-1">
    Upload a file
  </label>
  <input class="govuk-file-upload" id="file-upload-1" name="fileUpload1" type="file">
</div>
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.

Primary options

name string Required. The name of the input, which is submitted with the form data.
id string Required. The ID of the input.
value string Optional initial value of the input.
disabled boolean If true, file input will be disabled.

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.

<div class="govuk-form-group">
  <label class="govuk-label" for="file-upload-1">
    Upload a file
  </label>
  <input class="govuk-file-upload" id="file-upload-1" name="fileUpload1" type="file">
</div>

Error messages

Error messages should be styled like this:

<div class="govuk-form-group govuk-form-group--error">
  <label class="govuk-label" for="file-upload-1">
    Upload a file
  </label>
  <p id="file-upload-1-error" class="govuk-error-message">
    <span class="govuk-visually-hidden">Error:</span> The CSV must be smaller than 2MB

  },
  errorMessage: {
    text: "The CSV must be smaller than 2MB"

}) }}

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’.

Research on this component

An accessibility audit has shown some users have encountered a problem when using file upload.

Known issues and gaps

The file upload component does not show a visual target area when dragging and dropping a file. We do not plan on fixing this at the moment, as the component inherits and uses the browser’s default behaviour. We will revisit this issue if we publish a custom file upload component. More detail on the findings can be found in the GitHub issue: ‘Upload file component has no visual target area when dragging and dropping a file’.
