I have saved the meta key with the name writer_meta_key and want to retrieve it on my custom-functions page. I can get it on front page and single page but it doesn't work on my custom-function page. Here is my code. It gives only title but not the writer's name.
$term = get_queried_object();
$tax_object = get_taxonomy( $term->taxonomy );
$post_type_array = $tax_object->object_type;
$post_type = $post_type_array[0];
$posts = get_posts( array(
'post_type' => $post_type,
'taxonomy' => $term->taxonomy,
'term' => $term->slug
) );
foreach ($posts as $post) {
$id = get_the_ID();
$custom_meta_writer = get_post_meta( $id, 'writer_meta_key', true );
$writer = $custom_meta_writer['writer'];
echo $post->post_title;
echo $writer;
}
When I echo $id it shows error as
Array
Array
Array
Array
Where have I mistaken??

Where is your custom-function page used? Is it an include file called by a page template? – jdm2112 Commented Jan 30, 2019 at 19:04
- It's included in a folder inc and is called in functions.php – Jklyn Commented Jan 30, 2019 at 19:09
- It is important to remember that WordPress is an application that runs when a user requests content and does nothing otherwise (over-simplified) so my question is related to that. What triggers the code above to actually run? Typically custom functions (or plugins) are fired when the action they are hooked to is called. – jdm2112 Commented Jan 30, 2019 at 19:13
- First of all I'ven't used any plugins in this project. This is just a page where I've done all the codings. The above code displays the category posts and what I need is to retrive the meta key of the title. – Jklyn Commented Jan 30, 2019 at 19:20
- To simplify the question - how does this code get called? It isn't in a function hooked to an action. It is not part of a page template. How would WordPress know this code exists? – jdm2112 Commented Jan 30, 2019 at 19:30

Reset to default 0WordPress uses a global $post to keep track of the current post the user is viewing. Whenever you call functions like the_title() or get_the_ID() it uses that global $post to pull that data. In your code snippet you're using get_posts() which generally does not overwrite the global $post object unless you specify with setup_postdata( $post ).
The easiest thing to do is to simply modify your metadata line and use:
$custom_meta_writer = get_post_meta( $post->ID, 'writer_meta_key', true );
