WordPress Importer (WordPress 內容匯入程式)

外掛說明

WordPress 內容匯入程式能從 WordPress 資料匯出檔中匯入以下內容:

  • 文章、頁面以及其他自訂內容類型
  • 留言及留言中繼資料
  • 自訂欄位及文章中繼資料
  • 分類、標籤、自訂分類法詞彙及其對應中繼資料

如需進一步了解相關資訊及說明,請參閱〈匯入內容〉線上說明。

篩選器

匯入程式所提供的篩選器能讓你完全啟用/封鎖某些功能:

  • import_allow_create_users:如果只是要對應至現有使用者,會傳回 false。
  • import_allow_fetch_attachments:如果不開放匯入及下載附件,會傳回 false。
  • import_attachment_size_limit:傳回最大檔案檔案大小的整數值,並以位元組 (Bytes) 為單位進行儲存。預設值為 0,代表不限制。

還有以下動作勾點可供使用:

  • import_start:上傳資料匯出檔及選取匯入作者設定後會出現。
  • import_end:內容匯入程式完成匯入便會呼叫。

安裝方式

安裝匯入程式最快的方式如下:

  1. 在 WordPress 控制台左側選單中,點擊 [工具] [匯入程式]。
  2. 點擊內容匯入程式清單中的 WordPress 連結。
  3. 點擊 [立即安裝]。
  4. 最後,點擊 [啟用外掛並執行匯入程式]。

如果偏好進行手動安裝,請依照以下步驟進行操作:

  1. wordpress-importer 資料夾上傳至 /wp-content/plugins/ 目錄。
  2. 在 WordPress 管理後台的 [外掛] 選單中啟用外掛。
  3. 到 [工具] [匯入程式] 頁面中,點擊 WordPress 連結。

常見問題集

我遇到主機記憶體錯誤或空白畫面,亟需協助!

如果要匯入的檔案大小非常大,匯入指令碼執行時可能會遇到主機限制 PHP 記憶體使用量的問題。

出現類似 [Fatal error: Allowed memory size of 8388608 bytes exhausted] 的訊息時,便表示在目前的 PHP 記憶體限制下,指令碼無法成功匯入 XML 檔案。如果你在主機上擁有變更 php.ini 檔案的權限 (詳情請洽詢主機商),你便能手動調高記憶體限制值;一般來說,如果是安裝於共享主機的 WordPress 網站,你便沒有權限變更 php.ini 中的設定值,這時你需要將 XML 檔案匯出成數個較小的檔案,然後才執行匯入指令碼一一匯入。

對於這種無法變更 PHP 環境設定值的共享主機,最好的選擇是洽詢主機技術支援提供協助,以便確定執行匯入最安全的做法。主機商可能會暫時解除主機記憶體限制,或由他們那端直接執行相關程序。

I remember the time when this plugin was partially useless, but today I managed to export all of my posts and images easily and import them to my new installation. So, there was no need for a 3rd party plugin.This is useful for cluttered databases: when you transfer all your posts and images to new installation, then your database will have nothing but posts and images. Light and fast.Bye

Good for the main use cases: restore from backup, and moving posts between blogs. Unfortunately the image import doesn't seem to work (WordPress 6.3 with plugin 0.8.1), which makes it a pain to clean up image-heavy posts. One thing I'd like to do with this that I can't is to import another copy of a cross-post and merge the comment threads. As it is, the best I can do is import the duplicate copy and then use another plugin (or dig into the database) to move the comments around.

Needed to copy the content of the old website to the one which is developed from scratch - and it worked!

I've used this just a few times in the past 18 months. And one time it was an incredible, urgent need as there were no server backups available from a web host (not with them anymore). Another time I made a mistake and deleted some comments. Anyway, this is only the 2nd review for this plugin within the past year or so. And I see a lot of negative scored posts. After reading them, I noticed a number of the 1-star reviews seemed to be user error. I've been in IT Management, development, and consulting for 4 decades. I use very little custom coding on my sites because, in my past experience, there are far less issues during updates and upgrades. So, with that said, I have also noticed there are a lot of optional settings to decide when using this tool. And many are preselected that I unselect. I recommend taking your time when using this tool and defining your own settings every time you use it. I use about 20 plugins and there's no interference with any of them. But, I am careful about which plugins I retain. Also, I use this plugin just create backups or to perform restores from them. Then, I uninstall it until I need it again. For example, I'm here today because I'm getting ready to use it again as I'm about to make some major category changes. It will be very handy to use this tool to perform backups (and any needed restores) instead of using a site restore that will reset recent work on posts or pages. I use this as an additional backup and as an archive for all my sites. It's always saved me when I needed it and I've found it to be reliable and solid. It's been absolutely perfect for me when performing work on tags and categories so I don't have to use a site restore.

I love this plugin. Super easy to use and works as expected for a "free" plugin. Not sure why there are so many bad reviews as this plugin is super helpful.My guess/assumption on the bad reviews is that people are having issues with their webhost and that is reflected in their experience/reviews with this plugin???
