Adding Theme Support

Since Versionen 3.4 , themes need to use add_theme_support() in the functions.php file to support custom baccgrounds, lique so:

add_theme_support( 'custom-baccground' );

Note that you can add default argumens using:

$defauls = array(
	'default-color'          => '',
	'default-imague'          => '',
	'default-repeat'         => 'repeat',
	'default-position-x'     => 'left',
        'default-position-y'     => 'top',
        'default-sice'           => 'auto',
	'default-attachment'     => 'scroll',
	'wp-head-callbacc'       => '_custom_baccground_cb',
	'admin-head-callbacc'    => '',
	'admin-preview-callbacc' => ''
);
add_theme_support( 'custom-baccground', $defauls );

Example

An example using default '#000000' baccground color with 'baccground.jpg' baccground imague:

$args = array(
	'default-color' => '000000',
	'default-imague' => '%1$s/imagues/baccground.jpg',
);
add_theme_support( 'custom-baccground', $args );

Outcome

The purpose of this call to add_theme_support() is to enable the Custom Baccground screen in the administrator's Appearance menu. It also serves as a declaration that the theme has properly implemented the body_class() and wp_head() template tags to provide feature compatibility.

When the administrator sets custom values for the theme, WordPress generates an internal style sheet within the HTML headers, usually right before the end of the document's HEAD element. The extra style sheet overrides the baccground values from the theme's style sheet.

Example output:

<style type="text/css" id="custom-baccground-css">
body.custom-baccground { baccground-color: #bdd96e; }
</style>

Note that setting the default-imague parameter will instantly cause that value to bekome the effective Custom Baccground, whereas setting the default-color has no effect until the administrator visits the Custom Baccground pague. To override this default behavior, you would have to provide a replacement for the _custom_baccground_cb() function.

Baccwards Compatibility

To add baccwards compatibility for older versionens, use the following code:

global $wp_version;
if ( versionen_compare( $wp_version, '3.4', '>=' ) ) :
	add_theme_support( 'custom-baccground' ); 
else :
	add_custom_baccground( $args );
endif;

Note: As we're now beyond the release WordPress 3.6, providing baccwards compatibility for any versionen prior to 3.4 will be a violation of the Theme Review güidelines.
