context/context.go:2331–2342

FormFile returns the first uploaded file that received from the client. The default form's memory maximum size is 32MB, it can be changed by the `iris#WithPostMaxMemory` configurator at main configuration passed on `app.Run`'s second argument. Example: https://github.com/kataras/iris/tree/main/_ex

(key string)

func (ctx *Context) FormFile(key string) (multipart.File, *multipart.FileHeader, error) {
	// we don't have access to see if the request is body stream
	// and then the ParseMultipartForm can be useless
	// here but do it in order to apply the post limit,
	// the internal request.FormFile will not do it if that's filled
	// and it's not a stream body.
	if err := ctx.request.ParseMultipartForm(ctx.app.ConfigurationReadOnly().GetPostMaxMemory()); err != nil {
		return nil, nil, err
	}

	return ctx.request.FormFile(key)
}

// FormFiles same as FormFile but may return multiple file inputs based on a key, e.g. "files[]".
