仙劍奇俠傳5前傳支線 TP框架多上傳域上傳圖片

問題：

學習使用TP框架做電商網站是，新增商品表單需要上傳商品logo和商品圖片pics，有兩個上傳域，第一個上傳域是logo，只上傳一張，第二個上傳網域是pics，上傳多張圖片。使用以下程式碼，總是報錯：非法上傳檔案！

<span>$upload</span> =<span> \Think\Upload;
</span><span>$info</span>=<span>$upload</span>->upload();

解決方法：

有多個上傳域時，應如下使用upload方法，指定要處理的上傳域：

$upload = \Think\Upload;
$info1 = $upload->upload(array('logo'=>$_FILES['logo']);
$info2 = $upload->upload(array('pics'=>$_FILES['pics']);

Title:

TP上圖時圖片報錯「非法上傳"處理

Content:

TP框架上傳圖片時報錯「非法上傳"處理，主要注意以下兩點：

1.$_FILES中有多個上傳域問題，所以針對不同的上傳域，區別命名；

2.如同個上傳域中有一些沒有上傳圖片，則要重新收集好上傳的信息（收集成非空的一維數組）；

具體程式碼如下；
