Hi John,
Thanks so much for your time on this. I replaced the “// your code to output meta tags here” with the code above, and the following code was my block of text added to the functions.php of my child theme:
add_action('wp_head', 'product_details_meta');
function product_details_meta() {
// get the queried object
$queried_object = get_queried_object();
// see if it's a post
if (!is_a($queried_object, 'WP_POst')) {
// not a post
return;
}
// set $post_id
$post_id = $queried_object->ID;
// check post type
if (get_post_type($post_id) != 'product') {
// not a product
return;
}
// use $post_id to get ACF field values
$value = get_field('gtin', $post_id);
if (get_field('gtin', $post_id)) {
?>
<meta property="GTIN" content="<?php the_field(gtin', $post_id);?>" />
<?php
}
Sadly, it threw up a critical error on all pages of my site when I included this.
If you happen to see anything glaring that I mistakenly did with the code above, please let me know. Once again, thanks for your time and your help is greatly appreciated. Thanks again.
