Check if a different page has any attached images

Question

I am trying to make a notification function for a user's account dashboard that displays if they have not added any images to their profile's gallery. I found this page, which is a function that checks if the CURRENT page has any attachments: Check if post/page has gallery?

How can I change that to check by a specific post ID, i.e. a function that will check if post 2 has a gallery or not?

Answer 1

$args = array(
    'post_type' => 'attachment',
    'numberposts' => null,
    'post_status' => null,
    'post_parent' => $post_id
);
$attachments = get_posts($args);
if ($attachments) {
    echo "attachments rock!";
    }
}

If you want to make sure the atachements are an image, you would use:

if ( $attachments and wp_attachment_is_image( $post_id ) ) {
echo "attachments rock!";
}

Answer 2

According to that question you mentioned, you need to the have the post content in order to check if there is a gallery assigned to it. The function get_post is what you need.

$my_post = get_post($some_post_id);
if (strpos($my_post->post_content,'[gallery') === false){
  $gallery = 0;
}else{
  $gallery = 1;
}
