Hi, I am doing quite a bit of work with wordpress lately and learning its API.
1. Load single variable value from the custom field variable.
$event_date = get_post_meta($latest_events_page_id_array[$i]->ID, 'event-date', true); - return single variable value
2. Load the array of value from the same custom field variable.
$meta_description = get_post_custom_values('meta-description', $post->id); - return array
3. Use or modify “the_meta();” function in WordPress. It is located under wp-includes/post-template.php; we can use it directly or modify it to be used in child themes in WordPress.
