这里报错信息显示未定义变量，这是什么情况？

回复讨论(解决方案)

你去看看addscore.php 39行看看，你这个代码不会就是addscore.php里吧

服务器不支持上传
上传的文件超出了 post_max_size 的限制

你去看看addscore.php 39行看看，你这个代码不会就是addscore.php里吧
这个代码就是 addscore

你去看看addscore.php 39行看看，你这个代码不会就是addscore.php里吧
未定义的index是什么意思？image_upload这个是上传图片的name，为什么是未定义

entype写错了

应该是enctype

搞定了，万分感谢，为什么很明显的enctype写错了，报错却会是别的变量未定义？

接收的时候$_FILES是一个数组，里面有$_FILES['image_upload']这个数组成员，写错了没传过来，$_FILES数组为空，你后面的代码直接使用$_FILES['image_upload']，就提示没定义呗，再说这个提示是个Notice

哦，

非常感谢？我先在在学php，有什么好的资料，或者学习方法介绍下，我本专业不是计算机，学这个总是有种找不到方向的感觉
网上资料很多吧，我是之前看免费的课程，什么传智播客，兄弟连，基础的视频都有吧，多练就好了，像这种写错字母的错误刚开始都会有，自己慢慢调试就好了，我记得有个培训的老师说过，遇到错误先别着急，自己先一步步调试，实在不行上网查资料，然后实在不行再去请教别人，慢慢来
