Code and accessibility for file uploader

Apply required attributes

For the file uploader to function properly, always use the following attributes with <gcds-file-uploader>:

• name
• label
• uploader-id

Handle error messages and validation

• Use the required attribute to activate the required validator. Validation will happen by default on the onBlur event. A missing or invalid entry will prompt an inline error message with preset text.

• If you need to change the validation event, use the validate-on attribute. Validation can happen on blur, when the element loses focus, or manually with the validate() method.

• Use the required attribute for fields that must be filled in. This places "required" at the end of the label.

• Use the error-message attribute to include an error message text for all required inputs. Avoid using error messages for optional ones.

• For optional fields, avoid adding the error-message attribute.

• For an optional field that needs validation based on user input (like validating an email address format), opt to add custom validation with a custom error message.

Upload multiple files

Allow the selection of more than one file using the multiple attribute.

Validate file types for upload

Define the file types the file uploader accepts using the accept attribute.

Generate an instance of the component you need by selecting its code properties.

1. Explore by choosing different code values to generate the instance you want.

2. Get the code and pull it into your environment.

3. Add any copy you need to the component (like text for a label).

Note: The code builder uses English for all code elements, which follows standard practice.
