为了上帝的缘故，有人可以帮助我制作下面的脚本来上传多个图像（5）。我被困在这几天没有运气。我不知道如何让它上传五张图片。 Pleeeease帮助我。我试着把五个输入文件字段，并给他们一个像name="file[]"这样的名字，但似乎并没有工作。当我上传照片时，我看到一个错误说，请选择一张照片，即使有一个文件。php多个图像上传

首先，你需要分享你的尝试。没有人会为你做这项工作，但我们可以纠正你的错误。如果你坚持了几天，你应该有一些进步，对吧？ – 2013-02-18 00:31:59
我试图把5个文件字段放在窗体中，并给他们一个名字，如name =“file []”，但没有运气..我尝试了不同的事情，并意识到它不会工作，无论我尝试 – alte 2013-02-18 00:34:05
