function hook_plus1_access in Plus 1 6.2

Control whether voting is allowed.

Modules may implement this hook if they want to have a say in whether or not a given user is allowed to vote on a given node.

The administrative account (user ID #1) does not bypass this access check.

Note that not all modules will want to influence access. If your module does not want to actively grant or block access, return PLUS1_ACCESS_IGNORE or simply return nothing. Blindly returning FALSE will break other Plus1 access modules.

Parameters

$nid: The node id on which the vote is to be cast.

$op: The operation to be performed. Possible values:

• "create"
• "view"

$account: A user object representing the user for who is about to cast the vote.

Return value

PLUS1_ACCESS_ALLOW if voting is to be allowed; PLUS1_ACCESS_DENY if voting is to be denied; PLUS1_ACCESS_IGNORE to not affect voting at all.
