Answer 1

它可能是一个字符串而不是日期格式，因为你已经告诉它应该是mysql。 你可以试试这个：

  $query = "INSERT INTO teacher (name, father_name, mother_name, address, sex, position, subject, salary,dtime)VALUES('$name','$father','$mother','$address','$sex','$position','$subject','$salary',str_to_date($dtime, '%Y/%m/%d')"; 

Answer 2

您需要首先正确解析日期，例如，对于默认日期格式，请使用％m /％d /％Y。
