MySQL parameter error - php

Question

I'm trying to get my query to work for this PHP but I'm getting a "Invalid Parameter Number: number of bound variables do not match number of tokens" This is a snippet of my PHP:
<?php
/*
Our "config.inc.php" file connects to database every time we include or require
it within a php script. Since we want this script to add a new user to our db,
we will be talking with our database, and therefore,
let's require the connection to happen:
*/
require("configmob.php");
//if posted data is not empty
if (!empty($_POST)) {
//If the username or password is empty when the user submits
//the form, the page will die.
//Using die isn't a very good practice, you may want to look into
//displaying an error message within the form instead.
//We could also do front-end form validation from within our Android App,
//but it is good to have a have the back-end code do a double check.
if (empty($_POST['FirstName']) || empty($_POST['LastName'])) {
// Create some data that will be the JSON response
$response["success"] = 0;
$response["message"] = "Please Enter Both a First Name and a Last Name.";
//die will kill the page and not execute any code below, it will also
//display the parameter... in this case the JSON data our Android
//app will parse
die(json_encode($response));
}
//if the page hasn't died, we will check with our database to see if there is
//already a user with the username specificed in the form. ":user" is just
//a blank variable that we will change,Spot FROM Reservation WHERE Date = ':Date' AND Time = ':Time' AND Spot = ':Spot' ";
//now lets update what :user should be
$query = "Select * FROM Reservation WHERE Date = ':Date' AND TimeIn = ':TimeIn' AND Spot = ':Spot'";
$query_params = array(':Date' => $_POST['Date'] , ':TimeIn' => $_POST['Time'] , ':Spot' => $_POST['Spot']
);
//Now let's make run the query:
try {
// These two statements run the query against your database table.
$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 to product JSON data:
$response["success"] = 0;
$response["message"] = $ex->getMessage();
die(json_encode($response));
}
//fetch is an array of returned data. If any data is returned,
//we know that the username is already in use, so we murder our
//page
$row = $stmt->fetch();
if ($row) {
// For testing, you could use a die and message.
//die("This username is already in use");
//You could comment out the above die and use this one:
$response["success"] = 0;
$response["message"] = "I'm sorry, this Reservation is already Taken";
die(json_encode($response));
}
//If we have made it here without dying, then we are in the clear to
//create a new user. Let's setup our new query to create a user.
//Again, to protect against sql injects, user tokens such as :user and :pass
$query = "INSERT INTO Reservation (Fname, Lname, Garno, Gname, EmpID, CustID, License, Floor, Spot, TimeIn, TimeOut, Date, Confirmation)
VALUES (:Fname, :Lname, :Garno, :Gname, :EmpID, :CustID, :License, :Floor, :Spot, :TimeIn, :TimeOut, :Date, :Confirmation) ";
//Again, we need to update our tokens with the actual data:
$query_params = array(
':Fname' => $_POST['FirstName'],
':Lname' => $_POST['LastName'],
':Gname' => $_POST['Garage'],
':Date' => $_POST['Date'],
':TimeIn' => $_POST['Time'],
':Spot' => $_POST['Spot'],
':Confirmation' => $_POST['Confirmation'],
);
//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"] = $ex->getMessage();
die(json_encode($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;
$response["message"] = "Reservation Added!!";
echo json_encode($response);
//for a php webservice you could do a simple redirect and die.
//header("Location: loginmob.php");
//die("Redirecting to loginmob.php");
} else {
?>
<h1>Register</h1>
<form action="register.php" method="post">

Thank you for the help!

Answer 1

This is what I found in your second statement:
$query = "Select * FROM Reservation WHERE Date = ':Date' AND TimeIn = ':Time' AND Spot = ':Spot'";
$query_params = array(':Date' => $_POST['Date'] , ':TimeIn' => $_POST['Time'] , ':Spot' => $_POST['Spot']
);
Your :TimeIn should be :Time like follows:
$query_params = array(':Date' => $_POST['Date'] , ':Time' => $_POST['Time'] , ':Spot' => $_POST['Spot']
Update:
Also in your second query you have :Garno missing, please try the following:
$query = "INSERT INTO Reservation (Fname, Lname, Garno, Gname, EmpID, CustID, License, Floor, Spot, TimeIn, TimeOut, Date, Confirmation)
VALUES (:Fname, :Lname, :Garno, :Gname, :EmpID, :CustID, :License, :Floor, :Spot, :TimeIn, :TimeOut, :Date, :Confirmation) ";
//Again, we need to update our tokens with the actual data:
$query_params = array(
':Fname' => $_POST['FirstName'],
':Lname' => $_POST['LastName'],
':Garno' => $_POST['Garno'], // Hopefully $_POST['Garno'] is what you want.
':EmpID' => $_POST['EmpID'], // Hopefully $_POST['EmpID'] is what you want.
':CustID' => $_POST['CustID'], // Hopefully $_POST['CustID'] is what you want.
':License' => $_POST['License'], // Hopefully $_POST['License'] is what you want.
':Floor' => $_POST['Floor'], // Hopefully $_POST['Floor'] is what you want.
':TimeOut' => $_POST['TimeOut'], // Hopefully $_POST['TimeOut'] is what you want.
':Gname' => $_POST['Garage'], // You don't need this, remove this.
':Date' => $_POST['Date'],
':TimeIn' => $_POST['Time'],
':Spot' => $_POST['Spot'],
':Confirmation' => $_POST['Confirmation'],
);
