Show the category from permalink

  • Hi,

    I used this great plugin and would like to show the category I assigned in my post.
    I tried this code <?php the_category(); ?> and it will show all the categories instead the assigned one.
    How can I modify this code?

    Thank you!

    tdmalone’s solution is great, but I needed a small tweak to get it working:

    add_filter("get_the_categories","chr_primary_category");
function chr_primary_category($cats){
	global $post;
	$chr_catmeta=get_post_meta($post->ID,"_category_permalink",true);
	if($chr_catmeta=="") return $cats; // save our energy if there's no primary category set
	$specialcat="";
	foreach($cats as $key=>$cat){
		if($cat->term_id==$chr_catmeta['category']){
			$specialcat=$cat;
			unset($cats[$key]);
		}
	}
	if($specialcat!=""){
		$cats=array_merge(array($specialcat),$cats); // merge it all back together, with our special category first
	}
	return $cats;
}

    In my case, the chr_catmeta var was an array, so I needed to access it’s category member for the comparison to work.
