So this is a zany thing that I'm attempting to do, but what I am trying to achieve is querying out some info in WordPress with categories. If a post comes back with a parent category, then echo that out with the child category with a | seperator. If no parent category then just echo out the category.
Here's what I'm trying so far:
<?php
$categories = get_the_category();
$catName = $categories[0]->name;
$catParent = get_cat_name($categories[0]->category_parent);
if($catParent) {
$fullCat = $catParent '|' $catName;
} else {
$fullCat = $catName;
echo $fullCat;
?>
I know this is incorrect, but basically, I'm trying to wrap my head around how to accomplish this. I'm not sure how to combine two variables to use one and then add the separator within the two.
Was also wondering if maybe a ternary operator might be better here too? That was more of thought than anything and probably not that necessary to make this work correctly.
