post meta - get_post_meta not work in PHP foreach

I have these codes :

require_once( dirname(__DIR__) . '/wp-load.php');

foreach ( $ids as $idss ) {
    echo  get_post_meta($idss, 'IMDB', true);
}

I have search box with form element that search and find all id ( $ids ) of searched word.

I want to print all $ids's IMDB field. I can do it on page.php of the Theme, but I can't do it on header.php.

I used global $post; and it did not work.

Is your $ids array empty? Echo out each $idss to see if it contains a value.

foreach ( $ids as $idss ) {
  echo $idss . ' <-- ID<br>';
  echo  get_post_meta( $idss, 'IMDB', true );
}
