Function UploadedFileSize

core/validators/file.go:18–41

UploadedFileSize checks whether the validated [*filesystem.File] size is no more than the provided maxBytes. Example: validation.Field(&form.File, validation.By(validators.UploadedFileSize(1000)))

(maxBytes int64)

//
//	validation.Field(&form.File, validation.By(validators.UploadedFileSize(1000)))
func UploadedFileSize(maxBytes int64) validation.RuleFunc {
	return func(value any) error {
		v, ok := value.(*filesystem.File)
		if !ok {
			return ErrUnsupportedValueType
		}

		if v == nil {
			return nil // nothing to validate
		}

		if v.Size > maxBytes {
			return validation.NewError(
				"validation_file_size_limit",
				"Failed to upload {{.file}} - the maximum allowed file size is {{.maxSize}} bytes.",
			).SetParams(map[string]any{
				"file":    cutStr(v.OriginalName, 300),
				"maxSize": maxBytes,
			})
		}

		return nil
	}
}

// UploadedFileMimeType checks whether the validated [*filesystem.File]
// mimetype is within the provided allowed mime types.
