function spaces_dashboard_access in Spaces 7.3

Same name and namespace in other branches

1. 6.3 spaces_dashboard/spaces_dashboard.module \spaces_dashboard_access()
2. 7 spaces_dashboard/spaces_dashboard.module \spaces_dashboard_access()

Menu access callback.

Because spaces_dashboard provides a speciality callback for the user space which can be visible at the same time as the normal callback we need a slightly more complex access check for the main callback.

Parameters

$op: The operation to check access for, either 'feature' for whether the user may view the dashboard feature or 'admin' for whether the user may alter the dashboard in question.

$dashboard: String identifier for the dashboard page to check access on.

$type: The type of dashboard, 'user' or 'site'.

$space: The space to check access against. If not provided the current space will be used.
