What I'm simply trying to do is grab the featured image thumbnail image from a specified post/page and display that image on any other page somewhere.

So for instance, if it's a single post, use the thumbnail from post 9. If it's this page, use the thumbnail from 82, and so on.

It doesn't seem as simple as this:

$thumbnail_id = get_the_post_thumbnail(82);

Because I've tried that and it doesn't work in all scenarios.

Is there a universal way to do this?

  • What are you expecting the above code to do, exactly? You are loading the thumbnail's HTML into the $thumbnail_id variable, but not echoing it. – vancoder Apr 3 '13 at 23:05

Each post object has a public member $post_parent. That is the post ID of the parent post. So this should work:

$thumbnail = '';

if ( ( 'event_posts' == get_post_type()
        || is_page( 'events' )
        || is_page( 'restaurants' )
        || is_page( 'recreation' )
        || is_page( 'entertainment' )
        )
    && ! empty ( $GLOBALS['post']->post_parent )
    )
{
    $thumbnail = get_the_post_thumbnail( $GLOBALS['post']->post_parent );
}

echo $thumbnail;
  • I tried your suggestion but couldn't get it to work out. I also revised my question. – dragonfeet2012 Apr 9 '13 at 1:21

method 1)

<?php
$target_post_id = '999';
$feat_image = wp_get_attachment_url(get_post_thumbnail_id($target_post_id));
echo '$feat_image';
?>

method 2)

<?php 
$target_post_id = '999';
if (has_post_thumbnail($target_post_id) ): ?>
<?php $image = wp_get_attachment_image_src( get_post_thumbnail_id($target_post_id), 'single-post-thumbnail' ); ?>
<?php echo $image[0]; ?>
<?php endif; ?>

    Please add an explanation to your answer: why could that solve the problem? – fuxia Apr 9 '13 at 7:19

Looks like this might be the reason why it wasn't working the way I needed.

before -> if ( has_post_thumbnail () )

Seems that only relates to the specific post/page you're on, and not the page/page that you're getting the image from - if you don't enter a post ID. But then I tried it with the post ID I was trying to retrieve from and it works.

after -> if ( has_post_thumbnail (9) )

  • if you look at the function in codex, you'll see that you can pass the post id of the post you want to check. also, you're missing the parens on the function: if ( has_post_thumbnail() ). – Milo Apr 9 '13 at 1:48
