I’m looking for a way to get the ID of the background_image when I am using custom headers?
I tired using url_to_postid
like this:
$url = get_header_image()
$postid = url_to_postid( $url );
and
$url = get_theme_mod(‘header-image’)
$postid = url_to_postid( $url );
I got a null value for both, which I realized is because both get_header_image()
and get_theme_mod('header-image')
return the url in the form of example.com/wp-content/uploads… but what url_to_postid
needs is example.com/?attachment_id=#.
I also thought about get_theme_mods();
but it only returns the long url for background image. Not the shorter url or the ID. It does give the id for the header image though, grrr.
What am I missing here?
For the record I’m doing this so I can get the background image with wp_get_attachment_image_src()
in a dynamic stylesheet and use the $size arg, with some custom sizes to return a different size depending on the screen size. That way I can do full screen backgrounds without having to load and scale down some massive image for a phone’s screen. Alternative solutions to my actual problem are more than welcome.
