Duplicate Parent Category in Post Meta

    Okay so this theme didn’t originally have categories in the post meta and I finally added them, but then parents weren’t showing and I finally added them. Then however when I have multiple children I get the parent more than once: example. And I am officially over my head… is there any way to make it exempt duplicates? Or something? The code used is below:

    <span class="cat"><?php
$categories = the_category('  &  ', 'multiple');
$seperator = ' & ';
$output = '';
$parents = 'multiple';
if($categories){
	foreach($categories as $category) {
		$output .= '<a href="'.get_category_link($category->term_id ).'" title="' . esc_attr( sprintf( __( "View all posts in %s" ), $category->name ) ) . '">'.$category->cat_name.'</a>'.$seperator;
	}
echo trim($output, $seperator);
}
?></span>

    using the ‘multiple’ parameter will add the respective ancestor hierarchy to the output of each category; there is no way to exclude what you call ‘duplicate parent categories’.

    of your code, only this part actually does anything: the_category(' & ', 'multiple');

    because the_category() would directly echo the output and not return it to be used in a variable.

    what exactly are you trying to show, for instance in your example link?

    Reasons you should walk away when stuck. Really the best way for what I wanted was to check Book Review as a category and stop treating it as a parent seeing as I wanted list and not hierarchy. The code I used is below.

    <span class="cat"><?php
$categories = get_the_category();
$seperator = ' & ';
$output = '';
if($categories){
	foreach($categories as $category) {
		$output .= '<a href="'.get_category_link($category->term_id ).'" title="' . esc_attr( sprintf( __( "View all posts in %s" ), $category->name ) ) . '">'.$category->cat_name.'</a>'.$seperator;
	}
echo trim($output, $seperator);
}
?></span>
