PHP Fatal error:

Question

The following gives me an error on line 66.

Line 66 -> if ($result->fetch_array(MYSQLI_NUM) == NULL) {

Everything seems to be working according to the documentation.

I am trying to ensure that the Email address being inserted does not already exist.

$_email= $connection-> real_escape_string($email);

$checkSql='SELECT * FROM customer_registration WHERE EMAIL='.'"$_email"'.';';


$result= $connection -> query($checkSql);

//print_r($result);

$sql="INSERT INTO customer_registration(CUSTOMER_FNAME, CUSTOMER_LNAME,      CUSTOMER_DOB, APARTMENT, STREET, CITY, PROVINCE, POSTAL_CODE, EMAIL, PHONE, SIGN_IN_DATE)
    VALUES ('".$fname."','".$lname."',STR_TO_DATE('$dob','%m/%d/%Y'),'".$apt."','".$street."','".$city."','".$province."','".$postalCode."','".$email."','".$phone."',NOW());";


if ($result->fetch_array(MYSQLI_NUM) == NULL) {
    $connection->query($sql);           
    header('../login.php');
} else {            
    header('../index.php');         
}

The IF statement does not go though for any reason and I am not sure what is wrong. I checked the queries they are working but the if statement is not working.

Answer 1

$_email!=$email both are different change your query to

$email= $connection-> real_escape_string($email);

$checkSql="SELECT * FROM customer_registration WHERE EMAIL='".$email."'";

OR use bind statement and use num_rows() to check your query return result or not

$stmt = $connection->prepare("SELECT * FROM customer_registration WHERE EMAIL=?");
$stmt->bind_param("s", $email);
$stmt->execute();

$row_cnt = $connection->num_rows;

if ($row_cnt > 0) {
    $connection->query($sql);
    header('../login.php');
}
