Detailed Description

Restriction to make queries respect backend user rights for pages.

Adds a WHERE-clause for the pages-table where user permissions according to input argument, $permissions, is validated. $permissions is the "mask" used to select - see Permission Bitset. E.g. if $perms is 1 then you'll get all pages that a user can actually see! 2^0 = show (1) 2^1 = edit (2) 2^2 = delete (4) 2^3 = new (8) If the user is 'admin' no validation is used.

If the user is not set at all (->user is not an array), then "AND 1=0" is returned (will cause no selection results at all)

The 95% use of this function is "->getPagePermsClause(1)" which will return WHERE clauses for selecting pages in backend listings - in other words this will check read permissions.
