get_theme_data が 3.4で非推奨関数となり、wp_get_theme()になりました。
使い方は、以下のようにします。
<?php $theme_data = wp_get_theme(); $theme_uri = $theme_data->ThemeURI; $author_uri = $theme_data->Author_URI; $version = $theme_data->Version; $name = $theme_data->Name; $description= $theme_data->Description; $author = $theme_data->Author; $template = $theme_data->Template; $tags = $theme_data->Tags; $tags = implode(',',$tags); echo "version:{$version}<br /> name:{$name} <br /> description:{$description}<br /> author:{$author}<br /> template:{$template}<br /> {$tags}"; ?>
