Custom Field cascading system

    Hi WordPressers 🙂

    I have a custom field property ‘BannerImage’ for my pages.

    When it’s not filled in, it should find the ‘BannerImage’ of its parent. Is this hard to do?

    Thx for keeping me posted 🙂

    Kind regards,
    Yannick

    In theory, yes.

    if( !get_post_meta($post_id, 'BannerImage', true) ) $custom_field = get_post_meta($post->parent, 'BannerImage', true);
else $custom_field = get_post_meta($post_id, 'BannerImage', true);

    Oh esmi,

    Thank you!

    This is what I ended up with:

    if(!get_post_meta($post->ID, 'BannerImage', true)) {
		$banner_image = get_post_meta($post->post_parent, 'BannerImage', true);
	} else {
		$banner_image = get_post_meta($post->ID, 'BannerImage', true);
	}
	echo '<img src="' . $banner_image . '" />';

    Thx again for the quick help!

    Glad I could help – even if I did get $post->parent wrong (I should have checked first). 🙂
