Answer 1

您似乎在$reorder'之前错过了单引号？

Answer 2

SQL INSERT查询出错。

mysqli_query($con,"INSERT INTO product(prod_name,prod_price,prod_desc,prod_pic,cat_id,reorder,supplier_id,branch_id,serialn)
VALUES('$name','$price','$desc','$pic','$category','$reorder','$supplier','$branch','$serialn')")or die(mysqli_error($con))

现在试试..

Answer 3

在'尝试此代码之前，您已错过$reorder

 mysqli_query($con,"INSERT INTO product(prod_name, prod_price, prod_desc ,prod_pic, cat_id, reorder, supplier_id, branch_id, serialn) VALUES ('$name', '$price', '$desc', '$pic', '$category', '$reorder', '$supplier', '$branch', '$serialn')")or die(mysqli_error($con))or die(mysqli_error($con));
