For my project i'm trying to predict a paststudent's A level maths grade by using past student's data in my database. So paststudent1 got an A in maths A level. In year one exams they got an A in Computing, B in Physics, A in Chemistry, Male and 97% attendance. If the current student in Year 1 got the same grades, same subjects, male and same attendance i want to say they will get the same grade.
My error in my code says: "Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ' grade1 = 'Maths', 'A'' at line 1' in /home/u717042829/public_html/predicter.php:70 Stack trace: #0 /home/u717042829/public_html/predicter.php(70): PDOStatement->execute() #1 {main} thrown in /home/u717042829/public_html/predicter.php on line 70"
Line 70 is:
$query->execute();.
