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.$_FILES中有多个上传域问题，所以针对不同的上传域，区别命名；
2.如同个上传域中有一些没有上传图片，则要重新收集好上传的信息（收集成非空的一维数组）；
具体代码如下；
第一种情况：
<span>if</span>(<span>$this</span>-><span>_hasImg())
</span>02.<span> {
</span>03. <span>//</span><span> 只上传表单中name叫做jqimg的图片 </span>04. <span>$info</span> = <span>$upload</span>->upload(<span>array</span>('jqimg'=><span>$_FILES</span>['jqimg'<span>]));
</span>05. <span>if</span>(!<span>$info</span><span>)
</span>06. redirect(U('Ad/Ad/save/id/'.<span>$ad_id</span>), 3, <span>$upload</span>-><span>getError());
</span>07. <span>//</span><span> 循环每一张图片，插入到jq-info表 </span>08. <span>foreach</span> (<span>$info</span><span>as</span><span>$k</span> => <span>$v</span><span>)

</span>14. <span>//</span><span> 处理修改的图片 </span>15. <span>if</span>(<span>isset</span>(<span>$_POST</span>['oldjqtxt'<span>]))
