php圖像上傳mysql數據庫

Question

我的腳本有問題。它在我的託管服務器上傳圖像。在第二天或下週，主機服務器中沒有創建帶有圖像的文件夾，當然不是所有圖像都是 - 2周內的全部圖像的18-19％。我問他們。他們告訴我 - 問題出在我的php代碼中。如果有人能幫助，我會很高興。可能是我在mkdir（）中添加了一些0777？我不知道。我一直在想...

試試這個有效地看看如果mkdir創建沒有失敗。 其他文件夾和圖像肯定不會存在，即使它被添加到您的數據庫。

//previous code... 
mkdir("files/$code"); 
mkdir("files/thumbs/$code"); 

//change to this... 
if (!mkdir("files/$code", 0777, true)) { 
    die('Failed to create folders...'); 
} 

if (!mkdir("files/thumbs/$code", 0777, true)) { 
    die('Failed to create sub folders...'); 
}
