function votingapi_metadata in Voting API 7.3

Same name and namespace in other branches

1. 6.2 votingapi.module \votingapi_metadata()
2. 7.2 votingapi.module \votingapi_metadata()

Returns metadata about tags, value_types, and results defined by vote modules.

If your module needs to determine what existing tags, value_types, etc., are being supplied by other modules, call this function. Querying the votingapi tables for this information directly is discouraged, as values may not appear consistently. (For example, 'average' does not appear in the cache table until votes have actually been cast in the cache table.)

Three major bins of data are stored: tags, value_types, and functions. Each entry in these bins is keyed by the value stored in the actual VotingAPI tables, and contains an array with (minimally) 'name' and 'description' keys. Modules can add extra keys to their entries if desired.

This metadata can be modified or expanded using hook_votingapi_metadata_alter().

Return value

An array of metadata defined by VotingAPI and altered by vote modules.
