PHP PDO unable to insert the data in MySQL DB - mysql

Question

I am learning PHP.using XAMPPlocal server to test. Need help below
when I enter the details and click register in the form, I just see a blank page with the action.php link.
Code for action.php is below:
include 'config.php';
error_reporting(E_ALL);
ini_set('display_errors', 1);
if(isset($_POST['register'])){
require 'config.php';
$first_name = !empty($_POST['fname']) ? trim($_POST['fname']) : null;
$last_name = !empty($_POST['lname']) ? trim($_POST['lname']) : null;
$user_name = !empty($_POST['uname']) ? trim($_POST['uname']) : null;
$pass = !empty($_POST['upass']) ? trim($_POST['upass']) : null;
$user_email = !empty($_POST['umail']) ? trim($_POST['umail']) : null;
$sql = "INSERT INTO ams_users (id, firstname, lastname, username, password, email)
VALUES(?,?,?,?,?)";
$stmt = $pdo->prepare($sql);
$result = $stmt->execute(0,$first_name, $last_name, $user_name, $pass, $user_email);
if($result){
echo 'Thank you for registering';
}else{
echo 'sorry';
}
}enter code here
code for register.php form below:
<div class="reg-form">
<h1>Register</h1>
<form action="action.php" method="POST">
<p><label>First Name* :</label>
<input id="firstname" type="text" name="fname" /></p>
<p><label>Last Name* :</label>
<input id="lasttname" type="text" name="lname" /></p>
<p><label>User Name* : </label>
<input id="username" type="text" name="uname" /></p>
<p><label>Password: </label>
<input id="password" type="password" name="upass" /></p>
<p><label>E-Mail: </label>
<input id="e-mail" type="e-mail" name="umail"/></p>
<input type="submit" name="submit" value="register" />
</form>
</div>
MySQL table has 5 entries: id (autoincrement, firstname, lastname,username,password, and email.
please help where I am going wrong.

Answer 1

execute() takes an array of parameters not directly like you did.
You have less question marks then parameter
If you make id AUTOINCREMENTED then you can omit it from your query
So it becomes:
INSERT INTO ams_users (firstname, lastname, username, password, email)
VALUES(?,?,?,?,?)
Then you execute:
$result = $stmt->execute(array($first_name,
$last_name,
$user_name,
$pass,
$user_email)
);
Or:
INSERT INTO ams_users (id,firstname, lastname, username, password, email)
VALUES('',?,?,?,?,?)
The problem is you should have gotten the error, so make sure it is turned on:
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
