function _update_cache_set
| 7.x update.module | _update_cache_set($cid, $data, $expire) |
| 6.x update.module | _update_cache_set($cid, $data, $expire) |
Store data in the private update status cache table.
Note: this function completely ignores the {cache_update}.headers field since that is meaningless for the kinds of data we're caching.
Parameters
$cid: The cache ID to save the data with.
$data: The data to store.
$expire: One of the following values:
- CACHE_PERMANENT: Indicates that the item should never be removed except by explicitly using _update_cache_clear() or update_invalidate_cache().
- A Unix timestamp: Indicates that the item should be kept at least until the given time, after which it will be invalidated.
