As pointed out by @corey you need to set the enctype property for the form to multipart/form-data when dealing with file uploads. 正如@corey指出的那样，在处理文件上传时，需要将表单的enctype属性设置为multipart/form-data 。 It is possible and in fact desirable in many instances to also add a hidden input to limit the filesize to prevent large files taking a long time to process / fail but it's not essential. 在许多情况下，也有可能而且实际上很希望添加一个隐藏的输入来限制文件大小，以防止大型文件花费很长时间进行处理/失败，但这不是必需的。 On the serverside it is the $_FILES array that you need to check rather than $_POST 在服务器端，需要检查的是$_FILES数组，而不是$_POST
