im new here, hope to grow into this community.
I am currently learning php and i am making a program to upload a file. i found a tutorial with some code that makes a little sense to me but not really as i dont understand the lingo in php too well yet... so i have made the api to upload an image and i am testing via postman... so when i test im running a command in json to say {"upfile":"*whatever the base 64 encode is*"}.when i run this i get an error saying
Warning: Undefined array key "upfile" in C:xampphtdocsupload.php on line 37
Warning: Trying to access array offset on value of type null in C:xampphtdocsupload.php on line 37
i have tried to remove the ! from an if statement, which i will show below, but that give an invalid parameters error instead... any idea what i am doing wrong?
