[Widget Logic] Conditional check parent category help!

Update:

$parentCatList = get_category_parents($cat,false,',');
$parentCatListArray = split(",",$parentCatList);
$topParentName = $parentCatListArray[0];
$sdacReplace = array(" " => "-", "(" => "", ")" => "");
$topParent = strtolower(strtr($topParentName,$sdacReplace));
return (is_single() && ($topParent=="manga"));

Tried the above code in widget-logic,
I get this error:
Catchable fatal error: Object of class WP_Error could not be converted to string in /home/animepla/public_html/testing/wp-content/plugins/widget-logic/widget_logic.php(131) : eval()'d code on line 1

Another failed attempt… 🙁

Notes: I got the first part of the code from the first half of the code on this page: http://corpocrat.com/2008/10/31/how-to-get-parent-category-name-in-wordpress/

1. <?php
2. $category = get_the_category();
3. $parent = get_cat_name($category[0]->category_parent);
4. if (!empty($parent)) {
5. echo ‘» ‘ . $parent;
6. } else {
7. echo ‘» ‘ . $category[0]->cat_name;
8. }
9. ?>

There was an extra empty in the code that has been removed.

My current code above does have a glitch in it though which is addressed in the code above using an if statement. My idea is that rather than echo’ing the values, save them in a third variable like $topcat and then replace the final $parent in my code above with $topcat.

I tried this on my own and got this code:

$category = get_the_category();
$parent = get_cat_name($category[0]->category_parent);
if (!empty($parent)) {
$topcat = $parent;
} else {
$topcat = $category[0]->cat_name;
}
return (is_single() && ('Manga'==$topcat);

But that code gives an error and I can’t find the problem in it…

Any ideas?

I have seen that code before but when I tried it, I don’t think it worked.

If I remember correctly it needed the code below somewhere to make post_is_in_descendant_category(5) work. As I have had very little luck with if’s and function’s in widget-logic code this code didn’t work for me.

function post_is_in_descendant_category( $cats, $_post = null )
{
	foreach ( (array) $cats as $cat ) {
		// get_term_children() accepts integer ID only
		$descendants = get_term_children( (int) $cat, 'category');
		if ( $descendants && in_category( $descendants, $_post ) )
			return true;
	}
	return false;
}

Maybe I wasn’t doing it right so if this alternative is better than my current code, I welcome a working code that I could put straight into the widget-logic box.

Update on my code: (1 Edit + 1 Fix)

$category = get_the_category(); $parent = get_cat_id($category[0]->category_parent); return (is_single() && ('5'==$parent || in_category('5')));

The 1 Edit is “get_cat_id” to replace “Manga” with its category id “5”

The 1 Fix added the ” || in_category(‘5’) ” condition because without it, anything posted IN the top (parent) category returns false when some people might want it to be true. This is because the top (parent) category doesn’t have a parent category of itself so the $parent=”” instead of “5”.

In my case the top (parent) category is always empty and all my posts are in sub categories so I don’t really need the “Fix” but for the sake of others, there is it.
