WordPress 3.0では、WordPressテーマのカスタム背景という新機能が導入されました。この機能により、ユーザーは自分のサイトにカスタマイザーを追加することができ、ブログやサイトにユニークなタッチを与えることができる。この機能はコアに追加されていますが、テーマがサポートしている場合にのみ有効化されます。この投稿では、WordPress 3.0用のWordPressテーマでカスタマイザーを有効化する方法を紹介します。
注：この投稿はテーマデザイナーに特化した中級レベルの記事です。
更新：動画で使用したadd_custom_backgroundのコードは削除されました。この投稿の下のコードを見てください。

functions.phpファイルを開き、以下の行を追加するだけです：

その後、外観の下にカスタマイザーのオプションが表示されるはずです。
WordPress 3.0のデフォルトの20 10テーマには、すでにこの機能が有効化されています。

Hi, Is there the possibility to add some field settings via add_settings_field function ??
Michael
This has been depricated. Here’s the new code:
add_theme_support(‘custom-background’);
Editorial Staff
Thanks Michael. Updated the article.

Very certain that you can use custom fields to change the background on each post / page if you want.

There seems to be a problem. Just as I select the image file and click upload, it refreshes the page with no result. The ‘color’ thing works. And, I have tried many browsers.
Any help? Can we do it manually? As in, by some codes?
Editorial Staff
Do it manually via CSS codes.

What is the default size for wordpress backgrounds? i.e. what size should images be for them to fit properly in the background.
Editorial Staff
The best image is the one that can be repeated, so you keep the page load time small. WordPress will only show the background image that fits the screen resolution of the user.

Hey… that was cool. After my first comment, I am taken to a different page with more information about your website and commenting… how did you make that happen? Plugin?
I’d love to know more.
Editorial Staff
Its a plugin in our Recommended Plugins list. Go to our homepage and look there.

It is important to note that for this to work within a theme, you must add the wp_head() after your theme stylesheet link in the theme header. This new function adds blocks with the added color/background from within the wp_head() section, and if you call your stylesheet after the wp_head(), your stylesheet will override the custom background function.
I am torn, as I tend to call my stylesheet after the wp_head() call so that I can override styles added by plugins. May need to make a separate stylesheet for plugin overrides to be called later in the header.

Do you know how we do the custom header image as well?
Editorial Staff

So how does Wordpress know how to change the background? What if my current theme already has some background css attributes? Which one over-rides the other?
Editorial Staff
Your current theme would have to be made compatible with this feature. This is article is for theme designers who are creating themes and want to get WordPress 3.0 features in it. You would have to add the function for body class. If WordPress see that someone has updated the Custom Backgrounds page in the admin panel, then it will be prioritized. Otherwise the default background that you specify in the css file prevails.

Radical! I wonder, can these be done per post or page?
Editorial Staff
With the default function NO. For that you are better of using a plugin (several exist). The way this function works is it adds styling to the overall body class, so it will be the same for the entire site.
