However, I have a problem - i get this error message;

An error occurred in script 'C:\Users\David Morgan\Desktop\WEBSITES\hairz_&_graces\site\admin\add_product.php' on line 124:
mysqli_stmt_bind_param() expects parameter 1 to be mysqli_stmt, boolean given

How do I solve this as I think I have everything in place (variable associations, etc)?

Hi guys,

I have an error msg here, "Warning: mysqli_error() expects exactly 1 parameter, 0 given in D:\inetpub\vhosts\championtutor.com\httpdocs\tutor_registration3.php on line 598". I have highlighted the error line in red, do you guys have any idea what went wrong? Thanks

Warning:  mysql_fetch_assoc() expects parameter 1 to be resource, boolean given in C:\xampp\test.php on line 58

line 58 is the where the while loop starts.. what have i done wrong?

Code: [Select]
$query2 = mysql_query("SELECT student.SID, course.CID FROM student, course WHERE student.SID = `student-course.SID` AND course.CID = `student-course.CID` AND GRADE BETWEEN $beginning AND $grade",$this->connect);

$sid = $row['student.SID'];
$cid = $row['course.CID'];

echo "$sid-$cid";

}
