WordPress 前端前台使用wp_editor上传文件并附属绑定到文章

要在WordPress前台使用wp_editor上传文件并将其附加到文章，您需要进行一些自定义编程。wp_editor主要用于在后台编辑器中编辑内容，而不是用于前台上传文件。以下是一种可能的方法来实现您的需求：

// 创建一个表单，允许用户在前台上传文件 function custom_upload_form() {     ob_start();     ?>     <form method="post" enctype="multipart/formdata">         <input type="file" name="custom_upload" />         <input type="submit" name="submit_upload" value="上传文件" />     </form>     <?php     return ob_get_clean(); }  // 处理文件上传并将其附加到文章 function handle_custom_upload() {     if (isset($_POST['submit_upload'])) {         $file = $_FILES['custom_upload'];         $attachment_id = upload_custom_file($file);          if ($attachment_id) {             // 获取当前文章的ID（您可能需要根据您的情况来获取正确的文章ID）             $post_id = get_the_ID();              // 将附件与文章关联             update_post_meta($post_id, '_thumbnail_id', $attachment_id);         }     } }  // 上传文件并返回附件ID function upload_custom_file($file) {     require_once ABSPATH . 'wpadmin/includes/file.php';     require_once ABSPATH . 'wpadmin/includes/media.php';     require_once ABSPATH . 'wpadmin/includes/image.php';      // 检查上传目录是否存在，如果不存在则创建它     $upload_dir = wp_upload_dir();     $upload_path = $upload_dir['path'];     if (!file_exists($upload_path)) {         wp_mkdir_p($upload_path);     }      // 上传文件     $attachment = wp_handle_upload($file, array('test_form' => false));     if (!isset($attachment['error'])) {         // 创建附件         $attachment_data = array(             'post_mime_type' => $attachment['type'],             'post_title'     => sanitize_file_name($attachment['file']),             'post_content'   => '',             'post_status'    => 'inherit'         );          $attachment_id = wp_insert_attachment($attachment_data, $attachment['file']);         if (!is_wp_error($attachment_id)) {             require_once ABSPATH . 'wpadmin/includes/image.php';             $attachment_data = wp_generate_attachment_metadata($attachment_id, $attachment['file']);             wp_update_attachment_metadata($attachment_id, $attachment_data);              return $attachment_id;         }     }      return false; }  // 将自定义上传表单添加到文章内容 function add_custom_upload_form_to_content($content) {     if (is_single() && in_the_loop() && is_main_query()) {         $upload_form = custom_upload_form();         $content .= $upload_form;     }     return $content; }  add_filter('the_content', 'add_custom_upload_form_to_content'); add_action('init', 'handle_custom_upload');
