How to show post categories in a post?

It’s really not good looking but working.
I had the same problem with SKU and Categories, which DO appear in the default editor but not in the advanced editor, so I had to manually write them in. It creates the shortcode [display_sku_cat]. Just try it out.
Create a new .php file and put it in the plugins folder. You can just adapt it to your needs, which should be pretty easy to do. That’s coming from a php newbie who wrote this – me .. ;)

<?php
/*
Plugin Name: Display Article Number and Categories
Description: Creates a shortcode, [display_sku_cat id="n"], that displays the article number and categories of any WooCommerce product.
Version: 1.0
Author: Duke
Requires: PHP5, WooCommerce Plugin
*/

if ( in_array( 'woocommerce/woocommerce.php', apply_filters( 'active_plugins', get_option( 'active_plugins' ) ) ) ){
add_shortcode('display_sku_cat', 'display_sku_cat_shortcode');
}

function display_sku_cat_shortcode($atts) {
	global $post;
	
	extract(shortcode_atts(array(
		'id' => $post->ID,
		'link' => 'true',
	), $atts));

	if($link==='true'|$link==='false') {
		$link = ($link === 'true');
	}
	
	if(get_post_type($id)=='product'){
		ob_start();
		display_sku_cat($id);
		return ob_get_clean();
	}else{
		return "";
	}

}

function display_sku_cat($id="", $permalink=false ){
	global $wpdb;
	global $post;
	global $product;
	
	if(empty($id)){
		$id=$post->post_id;
	}
	
	if(is_bool($permalink)) {
		if($permalink){
			$link = get_permalink( $id );
		}
	}else{
		$link = $permalink;
		$permalink = true;
	}
	
	$target = "";		 
	if($newwindow == 'true'){
		$target="target='_blank' ";
	}
	
	if(get_post_type( $id )=='product'){
		$artikelnummer = $wpdb->get_var( "
		SELECT COUNT(meta value) FROM $wpdb->postmeta
		WHERE meta_key = '_sku'
		AND post_id = $id
		");

	}
	
	if ( wc_product_sku_enabled() && ( $product->get_sku() || $product->is_type( 'variable' ) ) ) : ?>

		<span style="font-size: 11px;">
		<span class="sku_wrapper"><?php _e( 'SKU:', 'woocommerce' ); ?> <span class="sku" itemprop="sku"><?php echo ( $sku = $product->get_sku() ) ? $sku : __( 'N/A', 'woocommerce' ); ?></span></span></br >

		<?php endif; ?>
	
		<?php echo $product->get_categories( ', ', '<span class="posted_in">' . _n( 'Category:', 'Categories:', $cat_count, 'woocommerce' ) . ' ', '</span>' ); ?>
		
		</span>
	<?php
	
}
