WordPress 后台直接复制文章并设置状态为草稿

在 WordPress 后台文章列表中，如果能直接复制一篇文章或页面，然后重新编辑后发表，是不是很方便。那为什么不全选复制文章内容，然后粘贴到新建文章中呢？这是因为这样做仅复制了文章内容，并未同时把原文章的相关信息一同复制过去，比如一些自定义字段等。l

利用) r -本文的一段代码，可以实现快速复制克隆一份文章，并保留原文章的所有信息。将代码添加到当前主题函数模板 functions.php 中：

// 复制文章
function zm_clone_post_as_draft(&% t + [ @ g#041; {
global $wpdb;
if (! ( isset( $_GET['post'4 D : :]/ ] 1 1 b F 5 ; W;) || isset( $_POST['post']) || ( isset($_REQUEST['action']) &a$ T F , Dmp;& 'zm_c{ I M #lone_post_as_draft' == $_REQUEST['action'] ) ) ) {
wp_die('No post to clone has been supplied!');
}
// Nonce 验证
if ( !isset&f ` | = - 9 J#040; $_GET X { } r1;'clone_nonce' c p ? r ; u ; -3; ) || !wM X =p_verify_nonce( $_GET['clone_nw | ) 4 _ 5 #once'], basename( __FILE__ A 7 n . d D c1; ) )Y W \ v o x;

// 所有文章数据
