将用户上传的文件保存到wordpress uploads文件夹

Question

我已经在wordpress中创建了一个页面，并且我已经放了这个表单。

<form action=""method="post"enctype="multipart/form-data">
<input type="file" name="file"><br>
<input type="text" placeholder="Your Name" name="name" />
<input type="submit" name="submit" value="Submit">
</form>

现在点击提交我希望用户上传的图片保存在文件夹中wp-content / uploads / [发布的用户名]

任何人都可以帮我解决wordpress中的后端处理部分。我已经尝试过wp_upload_bits，但是不能用它。

提前致谢。

wordpress的用户insert_attachment以保存附件，然后您还将具有获取具有不同样式的图像的功能，get_attachment（id，'full / medium / thumbnail'）。

$files = $_FILES['upload_attachment'];
foreach ($_FILES as $file => $array) {
  $newupload = insert_attachment($file,null);
  // save the $newupload with you from data, as psot id for the attachment
 }
 function  insert_attachment($file_handler,$post_id,$setthumb='false') {

    // check to make sure its a successful upload
    if ($_FILES[$file_handler]['error'] !== UPLOAD_ERR_OK) __return_false();

      require_once(ABSPATH . "wp-admin" . '/includes/image.php');
      require_once(ABSPATH . "wp-admin" . '/includes/file.php');
      require_once(ABSPATH . "wp-admin" . '/includes/media.php');
      $attach_id = media_handle_upload( $file_handler, $post_id );

   if ($setthumb) update_post_meta($post_id,'_thumbnail_id',$attach_id);
     return $attach_id;
 } 

在html中，如果您提交表单，图像将被上传，并且referances将保存在wp_post表中

<form action="upload_file.php" method="post" enctype="multipart/form-data">
   <label for="file">Filename:</label>
   <input type="file" name="upload_attachment[]" id="file"><br>
   <label for="file">Filename:</label>
   <input type="file" name="upload_attachment[]" id="file"><br>
   <label for="file">Filename:</label>
   <input type="file" name="upload_attachment[]" id="file"><br>
   <input type="submit" name="submit" value="Submit">
</form>
