syntax error, access violation pdo

Question

i am getting this error: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'INSERT INTO student_details (student_id, first_name, last_name, dob, address_lin' at line 2

for this code: any idea?

//create variables from each value that was submitted from the form */
$student_info_id = $_POST['student_info_id'];
$class_id = $_POST['class_id'];
$first_name = $_POST['first_name'];
$last_name = $_POST['last_name'];
$dob = $_POST['dob'];
$address_line_1 = $_POST['address_line_1'];
$address_line_2 = $_POST['address_line_2'];
$town = $_POST['town'];
$county = $_POST['county'];
$postcode = $_POST['postcode'];
$gender = $_POST['gender'];
$ethnicity = $_POST['ethnicity'];


try {
$conn = new PDO("mysql:host=$host; dbname=$dbname", $user, $password);
$conn->exec("SET CHARACTER SET utf8");      // Sets encoding UTF-8
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

 $sql = "

Answer 1

I'm not sure if PDO support multiple statements, but if so, the error is that you did not terminate the first statement,

INSERT INTO student_info (student_info_id, class_id) 
VALUES (:student_info_id, :class_id);
                                    ^ add this one

Answer 2

You'll have to finish the first INSERT with a ; Like this:

INSERT INTO student_info (
   student_info_id,
   class_id
) VALUES (
   :student_info_id,
   :class_id
); <-- a semicolon is the default statement separator, use it
....

Note that, although it is possible to run multiple queries at once, I would not advice you to do it. If you would run each query one by one you would have a better control over errors.

Answer 3

You can't run multiple queries in one call.
Run them separately, one by one.
