Let's take a look at lines 39 of addscore. php. your code won't be in addscore. php.

The server does not support uploading.
The uploaded file exceeds the post_max_size limit.

What does undefined index mean? Image_upload: the name of the uploaded image. why is it undefined?

Entype error

It should be enctype

Thanks very much. why is it obvious that the enctype is wrong, but the error is not defined by other variables?

$ _ FILES is an array containing $ _ FILES ['image _ upload']. the array member is incorrect. The $ _ FILES array is empty, the code behind you directly uses $ _ FILES ['image _ upload'], and the prompt is not defined. Besides, this prompt is a Notice.

Oh,

There are a lot of online materials. I used to watch free courses, broadcast intelligence podcasts, brothers, and basic videos. I just need to practice more, errors such as wrong letters can be found at the beginning, so you can debug them slowly. I remember a trained teacher said, don't worry about errors, and debug them step by step, I can't check the information online, but I can't consult other people.
