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, Dave -

That sounds perfect and would make an excellent filter.

So would _isParentSelected

It's a bit of a more specific than _isAncestorSelected.

Can we add that to you list too, please?!

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!

Dave -

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.

Dave -

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!
