仙剑奇侠传5前传支线 TP框架多上传域上传图片

问题：

学习使用TP框架做电商网站是，添加商品表单需要上传商品logo和商品图片pics，有两个上传域，第一个上传域是logo，只上传一张，第二个上传域是pics，上传多张图片。使用如下代码，总是报错：非法上传文件！

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

解决方法：

有多个上传域时，应如下使用upload方法，指定要处理的上传域：

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

TP框架上传图片时报错“非法上传"处理

Content:

TP框架上传图片时报错“非法上传"处理，主要注意以下两点：

1.$_FILES中有多个上传域问题，所以针对不同的上传域，区别命名；

2.如同个上传域中有一些没有上传图片，则要重新收集好上传的信息（收集成非空的一维数组）；

具体代码如下；

第一种情况：
