[Plugin: Map Categories to Pages] display page category

I wrote this function to solve this problem (excuse me if I’m not following php best practices, I’m new to php…old pro at JSPs though)

function get_current_location(){
	$locations_cat_id = 2;
	$ignore_ids = array();
	$ignore_ids[] = $locations_cat_id;
	$cats = get_categories( array( 'child_of'=>$locations_cat_id, 'parent'=>$locations_cat_id, 'hide_empty'=>0 ) );
	foreach($cats as $c){
		$ignore_ids[] = $c->cat_ID;
	}

	foreach((get_the_category()) as $category) {
		if ( !in_array($category->cat_ID, $ignore_ids) && cat_is_ancestor_of( $locations_cat_id, $category->cat_ID )) {
			return $category->cat_name;
		}
	}
	return "";
}

So, really I should have narrowed the above down to what was really getting the current page’s categories…I was up late, forgive me.

foreach ((get_the_category()) as $category) {
//Do something with your category here
//You could also pass in a page ID to get_the_category to get the categories for another page
}

Josie is correct.

global $post;
$cats=array();
foreach(get_the_category() as $category) {
	echo '<a href="'.get_category_link($category->term_id ).'">'.$category->cat_name.'</a>';
}
