PHP圖片上傳和調整大小錯誤

我看了網站找到我的問題的解決方案，但找不到答案。希望有人可以幫助我：PHP圖片上傳和調整大小錯誤

我有一個腳本，可以在不刷新頁面的情況下上傳和調整圖像大小。我在互聯網上找到它並對其進行調整以供我使用。腳本可以在下面找到。

我的問題：

首先upload.php程序的工作，但知道我得到錯誤數字9

我做了什麼來試圖解決它自己：

在本地機器和服務器上嘗試過，兩者都給出相同的錯誤編號9
刪除所有$ _POST並設置'static'vars，d idn't工作，並仍然得到了9號

有人可以幫我，TNX提前

嘗試刪除該行的@：

if([email protected]($im,$dir.$file,100)){

它抑制錯誤imagejpeg拋出。沒有它，你可能會看到你的問題。從以下行

如果它原來是內存的問題（永遠是我的第一個賭注），請記住，一個3000×3000像素的JPG吃起來不是9 MB，但至少3 x 3000 x 3000 = 27 MB的內存。 – 2010-01-05 14:40:47

刪除@：

if([email protected]($im,$dir.$file,100)){

@抑制錯誤。如果它被刪除並且display_errors處於打開狀態，則應該看到一個更具描述性的錯誤消息。

我的猜測是imagejpeg()由於權限不足而無法寫入文件。

媽，

我笨:(

至於建議我刪除了@，並用自己的眼睛看到我做了什麼錯。

錯誤是在我的目錄結構它是這樣的

$dir = $_POST['uploadPath'];是一個文件夾，將文件移動到「mainfolder/subfolder/imageFolder」，但它需要是「imageFolder /」，因爲我使用「子文件夾」中的upload.php文件。
