WordPress 獲取主題樣式表 style.css 注釋里的信息

我們在 Style.css 中都會填入自己的主題信息，例如名稱或版本號等，以便 WordPress 展現(xiàn)給用戶。以下是WP官方 2014 主題的注釋：

從中可以看到主題名稱、主題鏈接、作者、作者鏈接、版本等等信息。在 WordPress 3.4 以上的版本中，我們可以直接使用 wp_get_theme() 這個函數(shù)來獲取這些信息。以下是一些簡單的例子：

獲取當(dāng)前主題名字：

<?php
echo wp_get_theme();
?>

獲取其它主題名字：

<?php
$my_theme = wp_get_theme( 'twentyten' );
if ( $my_theme->exists() )
	echo $my_theme;
?>

獲取當(dāng)前主題版本號：

<?php
$my_theme = wp_get_theme();
echo $my_theme->get( 'Name' ) . " is version " . $my_theme->get( 'Version' );
?>

顯示當(dāng)前主題作者的鏈接：

<?php
$my_theme = wp_get_theme();
echo $my_theme->get( 'AuthorURI' );
?>
