I am trying to insert data into MySQL tables but I am not sure why it is not working
<?php
include 'connect.php';
$userName = $_POST['name'];
$firstname = $_POST['FirstName'];
$Surname = $_Post['Surname'];
$email = $_POST['EmailAddress'];
$password = $_POST['Password'];
$gender = $_POST['Gender'];
$dob = $_POST['DOB'];
$query = 'INSERT INTO `User` (`username`,`Password`,`First Name`,`Surname`, `Gender`, `DOB`, `Email Address`)
VALUES ('.$userName.','.$password.','.$firstname.','.$Surname.', '.$gender.', '.$dob.', '.$email.')';
$stmt = $conn->prepare($query);
try {
$myarray = array(
":userName" => $userName,
":password" => $password,
":firstname" =>$firstname,
":Surname" => $Surname,
":gender" => $gender,
":dob" => $dob,
":email" => $email);
print_r($myarray);
$stmt->execute($myarray);
} catch(PDOException $err) {
echo "Houston we have a problem: $err";
}
?>
Please tell me if I am doing something wrong.

Answer 1

You're using Prepared Statements wrong. With $db->prepare() you're actually submitting the query with placeholders and not with the values (called sending a template). In your case:
$query = 'INSERT INTO `User` (`username`,`Password`,`First Name`,`Surname`, `Gender`, `DOB`, `Email Address`)
VALUES (:userName, :password, :firstname, :Surname, :gender, :dob, :email)';

Answer 2

First make sure you have connected to the sql properly then change your codes to this one:
$table='User';
$sql="INSERT INTO
$table(username,Password,First Name,Surname,Gender,DOB,Email Address) VALUES ('$userName','$password','$firstname','$Surname', '$gender', '$dob', '$email')";
$result=$conn->query($sql) ;
Good Luck!

Answer 3

use this one for connection :
$db = "mysql:host=yourhost;dbname=yourdbname";
$username = " ";
$password = " ";
$conn = new PDO( $db, $username, $password ) or die("Error Connection !! ");
array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8");

Answer 4

Try this approach:
<?php
include 'connect.php';
$userName = $_POST['name'];
$firstname = $_POST['FirstName'];
$Surname = $_Post['Surname'];
$email = $_POST['EmailAddress'];
$password = $_POST['Password'];
$gender = $_POST['Gender'];
$dob = $_POST['DOB'];
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$query = 'INSERT INTO `User` (`username`,`Password`,`First Name`,`Surname`, `Gender`, `DOB`, `Email Address`)
VALUES (:userName, :password, :firstname, :Surname, :gender, :dob, :email)'
try {
$stmt = $conn->prepare($query);
$result = $stmt->execute(array(
":userName" => $userName,
":password" => $password,
":firstname" =>$firstname,
":Surname" => $Surname,
":gender" => $gender,
":dob" => $dob,
":email" => $email));
if ($result) {
// success!
echo 'lastInsertId = '.$conn->lastInsertId();
} else {
// Query failed.
echo 'errorcode = '.$stmt ->errorCode();
}
} catch(PDOException $err) {
echo "Houston we have a problem: $err <br />";
echo 'errorcode = '.$stmt ->errorCode();
}
