Adding post ID as a class to attachment images

    I have this code and it was working earlier but recently it stopped working, not sure why.

    function addclassfeaturedimage($attr) {
  remove_filter('wp_get_attachment_image_attributes','addclassfeaturedimage');
  $attr['class'] .=  get_the_ID() ;
  return $attr;
}
add_filter('wp_get_attachment_image_attributes','addclassfeaturedimage');

    When working it adds the post ID to the attachment image class.

    Any ideas?

    Hi WordpMoon12

    Your code works just fine for me. Why are you removing the filter inside the callback function? I don’t think selectors can start with a digit. Try it with a different selector with post id in it.

    function addclassfeaturedimage( $attr ) {
	$attr['class'] .= ' post-id-' .  get_the_ID();
	return $attr;
}

add_filter( 'wp_get_attachment_image_attributes', 'addclassfeaturedimage' );

    Now you can add css for the post like this

    .post-id-234 {

}
