isSiblingSelected?

Hi Perch,

I can add that to the next version and give you some code for it. How would we define _isSiblingSelected? All records at the same depth with the same parent as the selected category?

Or maybe just all categories with the same parent category as the selected category?

Hi Perch,

Try this:
- Open lib/viewer_functions.php
- Search for _hasSiblings
- Add the code in red:
$category['_hasSiblings'] = intval( !($category['_isFirstChild'] && $category['_isLastChild']) );

// added in 2.10
$category['_isSiblingSelected'] = intval( $selectedCategory && $selectedCategory['parentNum'] == $category['parentNum'] && !$category['_isSelected'] );
$category['_isParentSelected'] = intval( $selectedCategory && $selectedCategory['num'] == $category['parentNum'] );

$category['_listItemStart'] = _getListItemStartTags($prevCategory, $category, $nextCategory, $options);

Hope that helps, let me know if that works for you!

Brilliant. Thanks for this. It works really well.

Can we complete the deck and have _isChildSelected?

Again, it would be a bit more specific than _isDecendantSelected.

Hi Perch,

Sure, try this:

$category['_isChildSelected'] = intval( $selectedCategory && $category['num'] == $selectedCategory['parentNum'] );

Let me know if you need any other changes, otherwise I'll include these all in 2.10.

This is great. Better than great! Thanks.

Perch, can you provide some code showing how this came together... I thick this is just what I've been searching for.

Hi, Zick -

I'm currently building a site for a large and long-established charity. As such, their "About Us" section contains upwards of 30 different pages across various sub-sections. I wanted to introduce a localised sub-section menu which would enable readers to move around the related pages.

The category tree looks something like this:

[pre]Home
Articles
News
About Us
Our History
Page2
Page3
Page4

Our Founder
Page2
Page3
Page4

Etc...
[/pre]

So, in our example, if a reader was on the "Our History" page, I wanted to display a small menu showing just those links related to that sub-section:

[pre]Our History
Page2
Page3
Page4[/pre]

Achieving this (with simple code) using the current filters was proving difficult. The _isAncestorSelected or _isDecendantSelected snippets returned too many links - often the entire branch of the ancestory tree.

With Dave's updates all I need is this:

<?php
$subMenuLinks = "";
foreach ($categoryRecords as $menuCategory) {
if ($menuCategory['_isSelected'] || $menuCategory['_isParentSelected'] || $menuCategory['_isChildSelected']) {
$subMenuLinks[] = $menuCategory;
}
}
?>

This pulls out only those links which are directly related to each category in the sub-section.

Works a treat!
