[*parent*] TV & 0 id

Hello everybody
i am trying to use this default [*parent*] Template variable for navigation purpose :



This <head> element is supposed to be used by iCab / Opera & Link Widget Firefox Add On to link to the hierarchical parent of a document.
But i do not know how to deal with the "0" id :-/

Let see an example
My site (0)
-News (2)
--Today news (4)
--Yesterday news (5)
-Index (3)

If we are in the page "Today news" or "Yesterday news" the link work perfectly and point to "News"
But if we are in the page "News" or "Index" the link point to the "0" id document who did not exist.
I know than as a workaround i can put all the hierachy under "Index" but if it solve the proble for "News" and similars it will not solve it for "Index" main document (who is suppose to point to itself).

So
- Is an another way to create the "parent" link who avoid the problem of the "0" document ?
- is there a way to tell to the 0 document to redirect to the "main" page (Index in this case) ?

Hi,

you could use PHx or create a snippet to check the value before making the url.
If the value is equal to 0 then replace it with $modx->config[’site_start’]

:-)

or create your own "parent" tv with @eval

@EVAL $id = $modx->documentObject[’parent’]; if ($id == 0) { return $modx->config[’site_start’]; } else { return $id; }

Thanks you two this work perfectly (i have choice the "@eval method"). Il will probably post my "head chunk" latter
