public AccessResult::orIf(AccessResultInterface $other)
Combine this access result with another using OR.
When OR-ing two access results, the result is:
- isForbidden() in either ⇒ isForbidden()
- otherwise if isAllowed() in either ⇒ isAllowed()
- otherwise both must be isNeutral() ⇒ isNeutral()
Truth table:
1 2 3 4 5 | |A N F--+-----A |A A FN |A N FF |F F F |
Parameters
\Drupal\Core\Access\AccessResultInterface $other: The other access result to OR this one with.
Return value
static
