Keep go to Database Error 2 in my php script - php

Question

This is my shipmentrequest.php
<?php
require("config.inc.php");
if (!empty($_POST)) {
if (empty($_POST['name']) || empty($_POST['mobilenumber']) || empty($_POST['address']) || empty($_POST['city']) || empty($_POST['postcode']) || empty($_POST['state'])) {
// Create some data that will be the JSON response
$response["success"] = 0;
$response["message"] = "Please Enter the required marked ** field.";
die(json_encode($response));
}
else if (strlen($_POST['postcode']) < 5 || strlen($_POST['postcode']) >= 6) {
$response["success"] = 0;
$response["message"] = "Your postcode should be only 5 numbers.";
die(json_encode($response));
}
$query = "INSERT INTO shipmentrequest ( name, mobilenumber, address, city, postcode, state) VALUES ( :receivername, :receivermobilenumber, :receiveraddress, :receivercity, :receiverpostcode, :receiverstate) ";
//Again, we need to update our tokens with the actual data:
$query_params = array(
':name' => $_POST['name'],
':mobilenumber' => $_POST['mobilenumber'],
':address' => $_POST['address'],
':city' => $_POST['city'],
':postcode' => $_POST['postcode'],
':state' => $_POST['state']
);
//time to run our query, and create the user
try {
$stmt = $db->prepare($query);
$result = $stmt->execute($query_params);
}
catch (PDOException $ex) {
// For testing, you could use a die and message.
//die("Failed to run query: " . $ex->getMessage());
//or just use this use this one:
$response["success"] = 0;
$response["message"] = "Database Error2. Please Try Again!";
die(json_encode($response));
}
//If we have made it this far without dying, we have successfully added
//a new user to our database. We could do a few things here, such as
//redirect to the login page. Instead we are going to echo out some
//json data that will be read by the Android application, which will login
//the user (or redirect to a different activity, I'm not sure yet..)
$response["success"] = 1;
$response["message"] = "Shipping Service Succesfully Requested!";
echo json_encode($response);
//for a php webservice you could do a simple redirect and die.
//header("Location: login.php");
//die("Redirecting to login.php");
} else {
?>

I dont know why even I filled up my postcode textfield with 5 numbers only, It will just jump to the exceptional handling which is... Database Error2. Please Try Again! Can anyone tell me why it will go to the catch statement?

Answer 1

Looks like those tokens in $query doesn't match with what you put in $query_params array:
VALUES (:receivername, :receivermobilenumber, :receiveraddress, :receivercity, :receiverpostcode, :receiverstate)

Answer 2

binding parameter name values are not matched.
it should be :name, :mobilenumber, etc instead of :receivername, :receivermobilenumber, etc
$query = "INSERT INTO shipmentrequest ( name, mobilenumber, address, city, postcode, state) VALUES ( :name, :mobilenumber, :address, :city, :postcode, :state) ";
