JQ外掛程式ajaxFileUpload、php實作圖片，資料同時上傳 ajaxfileupload亂碼 ajaxfileupload ie8 ajaxfileupload ie

程式碼結構如下：

1、HTML程式碼，沒必要解釋了。

2、關於ajaxFileUpload插件，在下面程式碼中如果你使用的是JQ1.9以上請複製1-12到你的ajaxFileUpload程式碼中，JQ在很早就廢棄了handleError方法。註解關於程式碼的解釋很清楚。

這段php程式碼可以更改的可以上傳其他檔案和大小限制。 getimagesize

是判斷是否為病毒檔案更改後綴。

上述程式碼直接複製即可完成圖片和使用者資料的同時上傳。

回傳結果：[{"name":"d032a4ee7e957d956c8af0039d7e3085.jpg","error":0,"filesiz":{"0":720,"1":1280,"2":2,,3" "width="720" height="1280"","bits":8,"channels":3,"mime":"image/jpeg"},"path_name":"uploads/d032a4ee7e957d956c8af0039d7e3085.jpg"

以上就介紹了JQ外掛ajaxFileUpload、php實作圖片，資料同時上傳，包含了ajaxfileupload方面的內容，希望對PHP教學有興趣的朋友有幫助。
