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。

利用本文的一段代码,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。文章源自国外主机测评-https://www.zjcp.org/30572.html
将代码添加到当前主题函数模板 functions.php 中:文章源自国外主机测评-https://www.zjcp.org/30572.html
// 复制文章 function zm_clone_post_as_draft() { global $wpdb; if (! ( isset( $_GET[\'post\']) || isset( $_POST[\'post\']) || ( isset($_REQUEST[\'action\']) && \'zm_clone_post_as_draft\' == $_REQUEST[\'action\'] ) ) ) { wp_die(\'No post to clone has been supplied!\'); } // Nonce 验证 if ( !isset( $_GET[\'clone_nonce\'] ) || !wp_verify_nonce( $_GET[\'clone_nonce\'], basename( __FILE__ ) ) ) return; // 获取原文章ID $post_id = (isset($_GET[\'post\']) ? absint( $_GET[\'post\'] ) : absint( $_POST[\'post\'] ) ); // 所有文章数据 $post = get_post( $post_id ); // 如果不希望当前用户作为新文章作者,将下两行替换为$new_post_author = $post->post_author; $current_user = wp_get_current_user(); $new_post_author = $current_user->ID; // 如果发布数据存在,则创建发布克隆 if (isset( $post ) && $post != null) { // 创建新文章数组 $args = array( \'comment_status\' => $post->comment_status, \'ping_status\' => $post->ping_status, \'post_author\' => $new_post_author, \'post_content\' => $post->post_content, \'post_excerpt\' => $post->post_excerpt, \'post_name\' => $post->post_name, \'post_parent\' => $post->post_parent, \'post_password\' => $post->post_password, \'post_status\' => \'draft\', \'post_title\' => $post->post_title, \'post_type\' => $post->post_type, \'to_ping\' => $post->to_ping, \'menu_order\' => $post->menu_order ); // 通过wp_insert_post() 函数添加文章 $new_post_id = wp_insert_post( $args ); // 将新的文章设置为草稿 $taxonomies = get_object_taxonomies($post->post_type); // 返回文章类型的分类数组,例如:array(\"category\", \"post_tag\"); foreach ($taxonomies as $taxonomy) { $post_terms = wp_get_object_terms($post_id, $taxonomy, array(\'fields\' => \'slugs\')); wp_set_object_terms($new_post_id, $post_terms, $taxonomy, false); } // 查询复制所有文章信息 post meta $post_meta_infos = $wpdb->get_results(\"SELECT meta_key, meta_value FROM $wpdb->postmeta WHERE post_id=$post_id\"); if (count($post_meta_infos)!=0) { $sql_query = \"INSERT INTO $wpdb->postmeta (post_id, meta_key, meta_value) \"; foreach ($post_meta_infos as $meta_info) { $meta_key = $meta_info->meta_key; if( $meta_key == \'_wp_old_slug\' ) continue; $meta_value = addslashes($meta_info->meta_value); $sql_query_sel[]= \"SELECT $new_post_id, \'$meta_key\', \'$meta_value\'\"; } $sql_query.= implode(\" UNION ALL \", $sql_query_sel); $wpdb->query($sql_query); } wp_redirect( admin_url( \'edit.php?post_type=\'.$post->post_type ) ); exit; } else { wp_die(\'Post creation failed, could not find original post: \' . $post_id); } } add_action( \'admin_action_zm_clone_post_as_draft\', \'zm_clone_post_as_draft\' ); // 复制文章并添加到列表 function zm_clone_post_link( $actions, $post ) { if (current_user_can(\'edit_posts\')) { $actions[\'clone\'] = \'ID, basename(__FILE__), \'clone_nonce\' ) . \'\" title=\"Clone this \'.$post->post_type.\'\" rel=\"permalink\">复制\'; } return $actions; } add_filter( \'post_row_actions\', \'zm_clone_post_link\', 10, 2 ); add_filter(\'page_row_actions\', \'zm_clone_post_link\', 10, 2);
之后,进入WP后台 → 文章 → 所有文章,在文章标题下面会增加“复制”按钮,点击后会复制一份完全相同、状态为草稿的文章,同时支持页面及自定义文章类型。文章源自国外主机测评-https://www.zjcp.org/30572.html
