瀏覽器無法讀取包含特殊字符的文件名

Question

我有一個圖像，其文件名爲Chu Thái.jpg。當將其上傳到媒體庫時，主機中的文件名已被重命名爲Chu-Thái.jpg，但圖像的路徑與文件名不同：http://bem.vn/httq/wp-content/uploads/sites/2/2013/10/Chu-Thái.jpg

因此，當將url複製到瀏覽器時，該服務器上找不到該文件。

The requested URL /wp-head/wp-content/uploads/sites/2/2013/10/Chu-Thái-150x150.jpg was not found on this server.

我不知道這個問題是如何造成的Wordpress或通過我的主機？

Answer 1

問題是你不應該上傳帶有特殊字符的文件。我在plugin of mine中使用的是過濾器sanitize_file_name。

我結束了拉動和從this plugin適應3層的功能，這樣才能做一個全面的清理上傳的文件名，以免有這樣那樣的錯誤：

add_filter('sanitize_file_name', 't5_sanitize_filename', 10);
