Answer 1

Use this code:

  $sqlfail = "INSERT INTO  fail(fname,lname,tname,funame,idnum,m_phone,reg_date)
VALUES ('".$pfname."','".$plname."','".$ptname."','".$pfuname."','".$pidnum."','".$pm_phone."','".$todaydate."')";

make similar changes for update command as well

Answer 2

you actually have one error

$conn->query($sqlfail) 

should be

$conn->query($sqlfail);  

Answer 3

AND stats='$ok'";

我看不到具有此名称的变量，我认为您的意思是AND stats='ok'";
