All npspm
instructions used in the layout files of the
Content Management server except showIfLoggedIn
can be
parameterized. It might be necessary to do this in layout files, in which
npspm
elements are used for the elements of a list which is
generated only at runtime (a toclist
or a list of free links).
Parameterizing the npspm
instructions means using variables in
place of known fields of the exported file. Thus, the access permission of
the files determined by the list instruction can be checked:
<npsobj list="toclist"> <npspm showIfAccessible="@self"> ... </npspm> </npsobj>
To write HTML text (oder other text) to the output file only if a user is
a member of at least one of several user groups, the following
npspm
instruction can be used:
<npspm showIfMember="@memberList"> ... </npspm>
In the example above, memberList
represents a multi-selection
field that contains group names. As described in showIfMember, the group names may
also be specified directly using the vertical bar character as a separator.
This is the full sample code with which a list containing permission checks
for each element can be generated:
<ul> <npsobj list="toclist"> <npspm showIfMember="@memberList"> <li> <npsobj insertvalue="anchor" name="self"> <npsobj insertvalue="var" name="title" /> </npsobj> </li> </npspm> </npsobj> </ul>
The generated list contains only elements the user is permitted to access.
