Update

foreach ($_POST["sta"] as $key) {
echo $key;
    }

now I check three, just print three 1
bits. I know which one to change, but I have no idea that the object I want to change is subscription (Manager Edit list Product Statistics)

Database structure

so after I finished writing, I found that
I unexpectedly checked the WHERE condition
, so I could not find that the user had changed the value.
so my mind died again.
