Getting a parent in a loop on the frontpage

Hi guys, I’ve been trying to write some code with this magnificent MODx framework, I’ve come a long way now, but yet another challenge, been keeping me busy for two days now

Using Revo.
I managed to get the parent when retrieving a single blog post (since I’m building my own blog).

BUT, when I try to display the parent in the frontpage, I get nothing returned.

The code for my snippet is this:


And the code I’m using on my blog-post-retriever is included in a screenshot on line 22.

Anyone has an idea what I’m doing wrong? I hope it’s just a small thing, because I’ve tried about 15 ways to do it and all failed.

you can use the getResourceField - snippet

You’re missing an argument. It should be:

$field = $modx->getParent($id, 1, 'pagetitle');

Hey thanks for the tip, it still doesn’t work though, I get nothing replied. Don’t know what I’m overlooking so I will check out getResourceField too

Update:
Using resourcefield I got this:


Which returns: Personal
Which is OK.

But when I put it like this, since the category is dynamic:


I get nothing returned.

Anyone?
My guess is that I am trying to get the parent of the ’Home’ page. Since I’m including the script on the Home page?

When I print parent I get a ’0’ (zero). But when I echo the pagetitle, it does give me the correct title for the child...

Update2:
Ok one step further now:

This now returns me the correct parent number. How, how do I get the title?

Because this:

..doesn’t seem to work...

Last update:
Solved! YEASHHHHHHHHHHHHHHHHHHH!


Explanation:
In the Snippet guidelines it says to alternate cached and uncached snippets when placing them inside of eachother.
It’s explained to do so like this:


But actually putting it like that doesn’t work.
But like this it works:

First, all docs at the root of the Resources tree have no parent resource, so you’ll never get anything returned for them.

I think what you want is this to get the pagetitle of the current page’s parent (when it has one):

[[getResourceField? &id=`[[*parent]]` &field=`pagetitle`]]

As you can read in my last reply before this one, I discovered what needed to be done

Turned out like this:
