我有这种形式，需要文本输入，在它下面，你可以上传图像，最多四个（但它的可选，你可以选择不上传图像）。 然后将文本和图像或图像分配给数据库中当前登录的用户。 但是我有一个挑战，当我使用所有可用的图像上传输入时，它会成功上传并分配到数据库。 但是，当我上传少于4，1,2或3，没有反应。请帮助检查我的代码如下。我在图像上传的问题在php

这就是你希望我们给调试了你很多的代码。更具体地说“没有任何反应”。当然*会发生一些事情。什么？有错误吗？意外的结果？你检查了PHP错误日志吗？打开页面上的错误报告？检查数据库查询是否有错误？当*你*调试这个，特别是它失败的地方？ – David
@David它的很多代码，但错误很容易找到，不需要在这里更具体。你检查：if（isset（$ _ FILES ['upload_thread_image1']））{'然后你为image1，2，3和4分配所有的值。另外移动上传文件的一部分...如果图像已发布或检查是否存在if ...条件...如果没有，请不要执行'move_upload_file' ..现在您正尝试上传文件不存在，什么会导致错误。 – Twinfriends
@Twinfriends感谢您的解决方案！我将每个文件上传和move_upload_file直接分别放在每个文件上 – Donald3d
