php表單上傳並沒有爲上傳的文件分配任何權限

Question

嗨，大家好，我正在自定義一個joomla的房地產組件1.5該組件功能的一部分是網站管理員可以上傳PDF以配合描述個人房地產項目的方式與上傳項目圖片的腳本完全相同。事情是雖然表單上傳了腳本，但瀏覽網站的用戶實際上看不到它。他們點擊鏈接並得到403禁止的錯誤。 Web服務器可以看到該文件，但沒有人有權查看該文件。我檢查了包含pdf文件的文件夾的權限，他們沒事（755）。我已經檢查了上傳的PDF文件的權限，有時它們在Dreamweaver中顯示爲完全沒有權限，有時顯示爲644或600.我確實想過要將chmod命令合併到某處，但我正在工作與joomla和許多代碼是joomla特定的，這使得很難清楚地看到發生了什麼。你們能幫我解決問題嗎？代碼如下：

非常感謝

Answer 1

更改行（PropertiesControllerPdfs類），您嘗試更改文件的permisions：

chmod ($filename,0755); 

包含完整路徑以及文件名i，e：

chmod ($path.$filename,0755);
