Question

I am receiving 2 errors in my code below:

Warning: mysqli::prepare() [mysqli.prepare]: (21S01/1136): Column count doesn’t match value count at row 1 in … on line 115

Fatal error: Call to a member function bind_param() on a non-object in … on line 119

I am using mysqli and php code. What do I need to do in order to fix these errors?

CODE:

$insertsql = "
INSERT INTO Teacher
(TeacherForename, TeacherSurname, TeacherEmail, TeacherAlias, TeacherUsername, TeacherPassword, Code)
VALUES
(?, ?, ?, ?, ?, ?, ?, ?)
";
if (!$insert = $mysqli->prepare($insertsql)) {
// Handle errors with prepare operation here
}                                           

$insert->bind_param("sssssss", $getfirstname, $getsurname,
         $getemail, $getid, $getuser,
         $teacherpassword, $code);

$insert->execute();

if ($insert->errno) {
// Handle query error here
}

$insert->close();

You have too many parameters in your SQL:

INSERT INTO Teacher 
    (TeacherForename, TeacherSurname, TeacherEmail, TeacherAlias, TeacherUsername,   
    TeacherPassword, Code)
VALUES
    (?, ?, ?, ?, ?, ?, ?, ?)

There are 7 columns and 8 parameters.
