Question

我正在制作一个html问题表单。根据答案，它执行JavaScript算法。然后JavaScript获取它计算的数字并使用document.getElementById将答案放在隐藏的html表单中。 PHP将表单放入变量，并更新所选的MYSQL行。我没有显示实际的计算，因为它超过300行代码。每次单击“提交”时，数据库中的值都是空白的。感谢任何可以帮助我的人!!!

Answer 1

也许你会对变量使用相同的情况？如果你有var $ Q uestion4aa，它应该在mysql字符串中相同，而不是$ q uestion4aa

PHP表单不会基于javascript提交给MYSQL数据库
