Woocommerce custom code in child theme for the product list

I had the same problem when I updated the product_snippet_info.php for adding some extra content into the product info element shortcode. it only works when I put the code in the parent theme but it doesn’t when the code is in the child theme.

Thanks. It works for the product list now in the child theme. But the product info is not working yet. I updated the following function in the enfold/config-templatebuilder/avia-shortcodes/product_snippet_info.php. I tried to put the whole script into the function.php of the child theme but it will become error 500 on the frontend. I tried to comment out extended class “extends aviaShortcodeTemplate” and it fixed the error 500 problem but it shows nothing in the product info area.

		function shortcode_handler($atts, $content = "", $shortcodename = "", $meta = "")
		{
			$output = "";
			$meta['el_class'];
			
			global $woocommerce, $product;
			if(!is_object($woocommerce) || !is_object($woocommerce->query) || empty($product)) return;
			
			
			// $product = wc_get_product();
			$output .= "<div class='av-woo-product-info ".$meta['el_class']."'>";
			ob_start();
			
			// Disabled by Alex
			// $product->list_attributes();
			
			// Custom Code by Alex to add more product info data
			$string_item_code = 'Item-code';
		    if (ICL_LANGUAGE_CODE != 'en'){
		    	$string_item_code = '產品編號';
			}
			if ($product->sku != ''){
				echo '<div class="product_sku">'.$string_item_code.': '.$product->sku.'</div>';
			}
			if ($product->post->post_title != ''){
				echo '<div class="product_title">'.$product->post->post_title.'</div>';
			}

			if ($product->regular_price != ''){
				echo '<div class="product_price_row">';
				$product_o_price = $product->regular_price;
				$product_s_price = $product->sale_price;
				$product_symbol = get_woocommerce_currency_symbol();
				if ($product_symbol == '$'){
					$product_symbol = 'HKD$';
				}
				$product_symbol = 'HKD';
				if ($product_s_price == ''){ // No Discount
					if ($product_o_price != ''){
						echo '<span class="product_price">'.$product_symbol.wc_price($product_o_price).'</span>';
					}
				} else {
					echo '<span class="product_price">'.$product_symbol.wc_price($product_s_price).'</span>';
					echo '<span class="product_o_price"><del>'.$product_symbol.wc_price($product_o_price).'</del></span>';
					echo '<span class="product_percent">'.(($product_o_price - $product_s_price) / $product_o_price) * 100 .'% off</span>';
				}
				echo '</div>';
			}
			// end of custom code by Alex
			
			$output .= ob_get_clean();
			$output .= "</div>";
			
			
			return $output;
		}

I opened another question for the product info problem. So it can be easier for others with the same problem. Please refer to https://kriesi.at/support/topic/how-to-add-custom-product-info-element-to-child-theme

For the custom info in the product list, it has been solved. Thanks.
