将新WP查询保存到数组以在single.php上使用的函数

Question

Is it possible to run a function that always queries for a related post and saves that array to a variable in Wordpress?

if ( !function_exists( 'the_query_vars' ) ) {
function the_query_vars() {
  global $post;

  if ($post->post_status == 'publish') {  

    $args = array(
    'post_type' => 'sponsor'
    ,'posts_per_page' => 1
    ,'post_belongs' => $post->ID
    ,'post_status' => 'publish'
    ,'suppress_filters' => false
    );

    $sponsor_query = new WP_Query($args);
    return $the_query; 
  }
 add_action( 'init', 'the_sponsor_vars' );
} }

Then I just wanted to use the $the_query "object?" and use it as if I had done a regular new WP_Query() from within the template file? Calling it out with familiar hook like:

echo $the_query->post_title

Tried the simplest thing first: <?php print_r($the_query);?>

Been unsuccessful in returning the array of variables.

I considered that it was because the variable wasn't globally set, but I thought the advantage of the return command was to essentially store the results for use if the function is activated.

The function returns the Variable and not make it global. If you want to access the result you have to assign the result of the function to a variable.

if (!function_exists('the_query_vars')) {
    function the_query_vars()
    {
        global $post;

        if ($post->post_status == 'publish') {

            $args = array(
                'post_type' => 'sponsor'
            , 'posts_per_page' => 1
            , 'post_belongs' => $post->ID
            , 'post_status' => 'publish'
            , 'suppress_filters' => false
            );

            $sponsor_query = new WP_Query($args);
            return $sponsor_query;
        }
        add_action('init', 'the_sponsor_vars');
    }
}

and where you want to use the result of the function:

$the_query = the_query_vars();
