i feel like this is a dumb question - but i am not having any luck in searching for an answer so here it goes. i have a parent document with a child. is there a way i can put a link in my parent document to its child? i.e. <a href="link_to_child">link</a>

i’ve been looking through wayfinder and i don’t see how it can help solve this problem. i’m pretty new to modx and all it has to offer, so maybe i am searching in the wrong place.

any help is greatly appreciated. thank you!!

A document can have many children, so there’s no generic way to do it. If you know the ID of the child, you can do it with a simple link tag:

Evolution:

<a href="[~12~]">Child</a>

Revolution:

<a href="[[~12]]">Child</a>

Change 12 to the actual ID of the child resource.

If your sure the documents will only have one child, you can do it with a snippet. In revolution it would be something like this:

<a href=[[!ChildLink]]>Child</a>

<?php
/* ChildLink snippet */

$child = $modx->getObject('modResource', array('published'=>'1', 'deleted'=>'0','parent'=>$modx->resource->get('id') ));
return $child->get('id');

that was fast! so i tried this out and had to make a modification. i guess the way i have set things up may be more complicated than i thought. basically i have a page and in that page i display that parent’s children using getResources. each of those children will have one child as well.

so i changed the snippet code to this:

<?php
/* ChildLink snippet */

$parent= $modx->getObject('modResource', array('published'=>'1', 'deleted'=>'0','parent'=>$modx->resource->get('id') ));
$child = $modx->getObject('modResource', array('published'=>'1', 'deleted'=>'0','parent'=>$parent->get('id') ));
return $child->get('id');

it seems to work except that each of the links is the same id. does that make sense? is it even possible to do what i am trying to do?

I think you might be better off trying to use Wayfinder do to that rather than getResources. It’s designed to produce the tree as a set of links in a list.

Try using just this (replace 12 with the appropriate top-level parent):

[[!Wayfinder? &startId=`12`]]

return $child->get('id');

In a future site I will have that scheme
A detail in a child document... so I want to automagically generate those links, as well as parent link in child, where I will use something like <a href="[~[*parent*]~]">My Parent</a>

But... wich will be the link to child snippet code to work in evolution?

thanks, and sorry for the bad english

It’s more complicated in Evolution and I’m afraid I can’t remember how to do it. Someone else will have to answer.
