Get a value from a parent of a parent without defining the ID

How can I reference the parent ID upwards multiple levels?

I want to call a snippet in the documents (5)+(6) that references TVs of the ID (1) and call the same snippet in (15)+(16) that references TVs of the ID (10)

My tree structure of the documents is:

>web 

>>US (1)
>>>HOME (2)
>>>>FAQ (4)
>>>STORIES (3)
>>>>NEWS (5)
>>>>>LATEST NEWS (6)

>>DE (10)
>>>HOME (12)
>>>>FAQ (14)
>>>STORIES (13)
>>>>NEWS (15)
>>>>>LATEST NEWS (16)

I only figured out who to achieve this with defining the ID but not how I can tell the snippet to use the highest parent of the document:

<?php
$page = $modx->getObject('modResource', 1);
echo $page->getTVValue('tv_example_color');

Have you looked at the getResources add on? If I'm not misunderstanding, you should be able to do what you want with getResources easily. http://rtfm.modx.com/display/ADDON/getResources

Additionally, you'll want to use return instead of echo in your custom snippets within MODX.

As far as I understood getRecources I can only take the direct parent of a document but not the parent of the parent. I think depth works only downwards not upwards.

Have you had a look at the ultimateparent snippet?

You can specify how many levels you wish to travel etc.

If you want to get single fields use getResourceField together with UltimateParent

http://modx.com/extras/package/ultimateparent
http://modx.com/extras/package/getresourcefield

If you want output more than one field use getResources together with ultimateparent to get the Resource and its TVs all at once.

you can also use the @INHERIT - Binding as the TV-default-value.
This does inherit the value from parents to its children.

getResourceField together with Ultimate Parent would do that, or I have an extra which does both.

You'd use it like this:
[[setPlaceholders? &ph=`examplecolor == parent2.tv.tv_example_color`]]

That gets the value of the TV tv_example_color from the current document's parent's parent and stores it in [[+examplecolor]].

If you're writing your own snippet you can use getParentIds() to get an array of all of a resource's parents. Take a look here for an example.

Extras :: pThumb • Resizer • imageSlim • setPlaceholders
