That was it, it works now. I only tested it on product pages and didn’t realise the problem was when the code ran on the others.

Thank you so much, I wouldn’t have managed without your help! Keep up the amazing work! ??

Sure @3sonsdevelopment , no worries:

function facebook_open_graph() {
	global $post, $wp_query;
	$postID = $wp_query->post->ID;
	$product = wc_get_product( $postID );

	
	if ( !is_singular()) //if it is not a post or a page
		return;
		if($excerpt = $post->post_excerpt) 
	        {
 			$excerpt = strip_tags($post->post_excerpt);
			$excerpt = str_replace("", "'", $excerpt);
        	} 
        	else 
        	{
            		$excerpt = get_bloginfo('description');
		}

	echo '<meta property="og:title" content="' . get_the_title() . '"/>';
	echo '<meta property="og:description" content="' . $excerpt . '"/>';
	echo '<meta property="og:type" content="article"/>';
	echo '<meta property="og:url" content="' . get_permalink() . '"/>';
	echo '<meta property="product:condition" content="new"/>';
	echo '<meta property="product:price:currency" content="RON"/>';
	echo '<meta property="product:price:amount" content="' . $product->get_price() . '"/>';
	echo '<meta property="product:retailer_item_id" content="' . $product->get_sku() . '"/>';

	//Twitter card
	echo '<meta name="twitter:card" content="summary" />';
	echo '<meta name="twitter:description" content="' . $excerpt . '" />';
	echo '<meta name="twitter:title" content="' . get_the_title() . '" />';
   
	echo '<meta property="og:site_name" content="Uzina de Carte"/>';

	//Create a default image if none exists
	if(!has_post_thumbnail( $post->ID )) {
		$default_image="https://www.uzinadecarte.ro/wp-content/uploads/2016/04/logo-udc-septmbriey.png"; 
		echo '<meta property="og:image" content="' . $default_image . '"/>';
		echo '<meta name="twitter:image" content="' . $default_image . '" />';
	}
    else{
		$thumbnail_src = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'medium' );
		echo '<meta property="og:image" content="' . esc_attr( $thumbnail_src[0] ) . '"/>';
		echo '<meta name="twitter:image" content="' . esc_attr( $thumbnail_src[0] ) . '" />';
	}

}
add_action( 'wp_head', 'facebook_open_graph', 5 );

I have also tried to use
$data = $product->get_data();
to access the array, but I receive an error again: Uncaught Error: Call to a member function get_data() on boolean in wp-content/themes/shopkeeper-child/functions.php:52

Hey @3sonsdevelopment

Again, thanks for the response. I did that change, and now I get: Uncaught Error: Call to a member function get_sku() on boolean in wp-content/themes/shopkeeper-child/functions.php:44
get_price() doesn’t work either, I’ll just use sku as an example because it’s easier to talk about just one of them ??

Running a var_dump on $product now does give me a lot of information. It seems the sku is here (I removed additional lines, cause it’s a lot of them):

object(WC_Product_Simple)#1612 (12) {
  ["data":protected]=>
  array(49) {
    ["sku"]=>
    string(7) "9478290"
  }
}

I tried to get the sku from the array with $product[‘sku’]; but I just ended up with a blank page.

Hey @3sonsdevelopment ,

Thanks for the quick response!

I just tried doing those changes, even just copy the code from the linked article, but I keep getting this error: Uncaught Error: Call to a member function get_sku() on null in wp-content/themes/shopkeeper-child/functions.php:63

If I do a var_dump on $product, I only get the product’s name, such as:
string(21) "stilou-exclusiv-metal"

Any idea what’s going on? Or is this something that can be caused by the theme?
