add_filter('pre_set_site_transient_update_themes', 'theme_update');
add_action('delete_site_transient_update_themes', 'deleteStoredData')  
function get_current_theme( $name=false ){
    $theme = wp_get_theme();
    if($theme->get('Template')){
        return $name ? $theme->parent()->get('Name') : $theme->template;
    }else{
        return $name ? $theme->get('Name') : $theme->stylesheet;
    }
}
function theme_update($value){
	$new_version='2.9.6';//新版
	$new_url='https://www.ruikeedu.com/chameleons/';//介绍页
	$new_package='https://www.ruikeedu.com/chameleons/xxx.zip';//下载包
	//以上数据可以定义为post接受参数来赋予，这样可以很好的保护我们主题下载包，你可以加授权验证账号网站等

    $state = get_option('update_chameleonS');
    if ( empty($state) ){
        $state = new StdClass;
        $state->lastCheck = time();
        $state->checkedVersion = $version;
        $state->update = null;
    }
    if(version_compare($version, $new_version)<0) {
        $state->update = new StdClass;
        $state->update->version = $new_version;
        $state->update->url = urldecode($new_url);
        $state->update->package = urldecode($new_package);
        update_option('update_chameleonS', $state);
    }
    global $theme_update_state;
    if(!isset($theme_update_state)) $theme_update_state = get_option('update_chameleonS');

    if ( !empty($theme_update_state) && isset($theme_update_state->update) && !empty($theme_update_state->update) ){
        $update = $theme_update_state->update;
        $value->response[get_current_theme()] = array(
            'new_version' => $update->version,
            'url' => $update->url,
            'package' => $update->package
        );
    }
    return $value;	
} 
function deleteStoredData(){
