PHP & MySQL no inserting data into table (PDO) - php

Question

I am having trouble getting a record to insert into my database, I have checked the code and all the variables and names match between PHP and the database.
There are no error messages and I am getting the text saying booking was created but, no record is entered into the database.
Here is the php code for inserting the record;
<div class="containter">
<?php
if (isset($_POST['submit'])) {
try {
include ('include\PDO.php');
$sql = "INSERT INTO customers(Customer_Name, Customer_Email, Customer_Contact) VALUES (:Customer_Name, :Customer_Email, :Customer_Contact)";
//Named Parameters
$stmt = $dbh->prepare($sql);
if (!$stmt) {
echo "\nPDO::errorInfo():\n";
print_r($dbh->errorInfo());
}
$Customer_Name = filter_input(INPUT_POST, 'Customer_Name');
$stmt->bindValue(':Customer_Name', $Customer_Name, PDO::PARAM_STR);
$Customer_Email = filter_input(INPUT_POST, 'Customer_Email');
$stmt->bindValue(':Customer_Email', $Customer_Email, PDO::PARAM_STR);
$Customer_Contact = filter_input(INPUT_POST, 'Customer_Contact');
$stmt->bindValue(':Customer_Contact', $Customer_Contact, PDO::PARAM_STR);
print $Customer_Contact;
print $Customer_Name;
print $Customer_Email;
$stmt->execute();
$dbh = null;
} catch (PDOException $e) {
//Error Messages
print "We have had an error: " . $e->getMessage() . "<br/>";
die();
}
?>
<p> Booking Created.</p>
<?php } else { ?>
<form action ="<?php echo htmlentities($_SERVER['PHP_SELF']); ?>" method="post">
<label>Name:</label> <input type="text" name ="Cusomer_Name">
<label>Email:</label> <input type="email" name ="Cusomer_Email">
<label>Contact:</label> <input type="tel" name ="Cusomer_Contact">
<input type="submit" name ="submit">
</form>
<?php } ?>
</div>
</body>
</html>
I have checked everything I can think of but I just cannot seem to get the records to add to the database.
Any ideas of what I'm doing wrong?

Answer 1

In the html form you have:
<label>Name:</label> <input type="text" name ="Cusomer_Name">
In the php code you filter Customer_Name:
$Customer_Name = filter_input(INPUT_POST, 'Customer_Name');
There is a missing 't' in the html form.
Put Customer_Name instead of Cusomer_Name in the html form and do the same thing for Cusomer_Email and Cusomer_Contact

$stmt->execute(); returns boolean with answer. Try following snippet to figure out where exactly problem is:
$success = $stmt->execute();
if (!$success){
print $stmt->errorInfo()[2]; //PDO driver error message
}
