[SOLVED] Wayfinder question

Hi all. This is my first post in the forums - but hopefully not the last wink

I have a menu structure in 3 levels. I need to create a wayfinder call that says:
"When in level 2, make a list of my children
when in level 3 make list of my parents children (my siblings)"

I can’t seem to find a way to do that. But I’m only a modx n00b

The parameter that makes the menu behave as you describe is &hideSubMenus. Set this to &hideSubMenus=`TRUE` and the sub menus will only show when the section is active.

There is a whole lot of cool Wayfinder info at:

Sorry, I don’t understand what you want to do ...
Could you explain more, maybe with an example document tree ?

Ex.

Level 1 Page 1
--- Level 2 Page 1
--- --- Level 3 page 1
--- --- Level 3 page 2
--- --- Level 3 page 3
---Level 2 Page 2
Level 1 Page 2
Level 1 Page 3

I need a Wayfinder call that does the following:
When viewing a level 2 document, output a list of the level 3 documents.
When viewing a level 3 document, output a list of the level 3 documents.

The way I do it now is using 2 calls:
[!Wayfinder? &startId=`[*id*]`&level=`1`!]
[!Wayfinder? &startId=`[*parent*]`&level=`1`&excludeDocs=`22,23,24`!]
excludeDocs being the level 1 id’s so I don’t get them when viewing a level 2 page.

It works but it’s ’static’, meaning I have to update the template every time I add a new level 1 document sad

Did that make it any clearer? huh

I think the simpliest way is to write a snippet which decides which value to put into &startId parameter.
Your Wayfinder call will become:
[tt][!Wayfinder? &startId=`[!theSnippetName!]`&level=`1`!][/tt]

The snippet code could be:

<?php
switch (count($modx->getParentIds($modx->documentIdentifier))) {
case 1: // we're in level 2
  return $modx->documentObject['id'];
case 2: // we're in level 3
  return $modx->documentObject['parent'];
default: // other levels
  return 0;
}
?>

Hi Enidan

Thank you for your answer.

When I try what you suggest It outputs the following:
&level=`1`]]

I made the snippet and called it as you suggested. Did you try this on a system? Did it work?

You need to alternate the snippet call types; the inner snippet should be uncached [[...]] and the outer snippet cached [!...!].

You’re a genius! Thank you very much. I needed to edit the snippet to

<?php
switch (count($modx->getParentIds($modx->documentIdentifier))) {
case 0: //we're in level 1
 return $modx->documentObject['id'];
case 1: // we're in level 2
  return $modx->documentObject['parent'];
case 2: // we're in level 3
  return $modx->documentObject['parent'];
default: // other levels
 return 0;
}
?>

so it included level 1, but I couldn’t have done it without your help. Thank you very much!
