一些主題的底部會有一個年限版權的樣式，例如2017-2020這樣，如果是自己手動改的話，那也太麻煩了，不如讓WordPress實現動態版權。

• 代碼來源：詳情

在主題文件夾下的的functions.php的<?php下輸入下面的代碼：

function copyrightDate() {
    global $wpdb;
    $copyright_dates = $wpdb->get_results("
		SELECT
			YEAR(min(post_date_gmt)) AS firstdate,
			YEAR(max(post_date_gmt)) AS lastdate
		FROM
			$wpdb->posts
		WHERE post_status = 'publish'
	");
    if ($copyright_dates) {
        $date = date('Y-m-d');
        $date = explode('-', $date);
        $copyright = "" . $copyright_dates[0]->firstdate;
        if ($copyright_dates[0]->firstdate != $date[0]) {
            $copyright .= '-' . $date[0];
        }
        echo $copyright;
    }
}

前臺調用：

<?php copyrightDate();?>
