API receiving Half Data

I have a PHP API but when I send data to it using a post or get request the API receives half data, I don't know what the issue is. this same API works on the localhost but gives error on the Public server.
API sendrequset URL:
https://peer.infusiblecoder.com/android/loanapp/sendrequesttoperson.php?request_is_seen=hjhj&loan_request_code=100&req_status=hjh&request_sender_user_name=ghjgjh&request_reciver_user_name=hjhjh&request_sender_user_id=jkjkj&request_reciver_user_id=hjhj&request_time_stamp=ghhgjhh

it gives this result

The problem is $_GET["$req_status_db"]
It should be $_GET["req_status_db"]
You will have to remove $ from all the $_GET keys.
Also, you do not have req_status_db as query param in the URL you have shared.

How to embed Javascript function in restful api in php?

I have the following code in one of api files(DispatchJob_Public) and i need ajax here to call the other file(selectDriverForJobResult) after 2 minutes. I can do that in php with sleep(), but that will keep the server busy. Ajax call is at the end of the php code. Can i embed js in api code? Or is there any alternate to do what i am trying to do.
Moreover i have got response from the first file(DispatchJob_Public), but no response from the second file(selectDriverForJobResult) when i called the endpoint in postman. Because the call wasn't made. If the second file was called, it should have return some response. The strange thing is that i get response from second file when i run it in browser. I think that is because the browser supports the javascript but the call made from android to the end point doesn't support that.
Please can i get any solution for this?

JSON_encode not outputting anything

I want to send a query result from one php file to my javascript, I've used an AJAX which seems to work as it is getting data from my BaseClass.php. However when using JSON_encode, it is not outputting anything at all. So I can't work out how to send a query result from one php file(MySQLDao.php) to my BaseClass.php so I am then able to send it to my Javascript file.
My Code:
BaseClass.php:
<?php
error_reporting(E_ALL); ini_set('display_errors', 1);
require("Conn.php");
require("MySQLDao.php");
//$param=$_REQUEST['action'];
//echo json_encode($_GET);
//echo var_dump(json_encode($_GET));
$handle = fopen("php://input", "rb");
$param = $_REQUEST['action'];
while (!feof($handle)) {
$param .= fread($handle, 8192);
}
fclose($handle);
if (empty($param))
{
$returnValue["status"] = false;
$returnValue["title"] = "Error";
$returnValue["message"] = "No Data Recieved paige" .$param ."...";
echo json_encode($returnValue);
return;
}
else
{
$dao = new MySQLDao();
if ($dao->openConnection() == false)
{
$returnValue["status"] = false;
$returnValue["title"] = "Error";
$returnValue["message"] = "Connection Could Not Be Established Between Server And Database";
ob_clean();
echo json_encode($returnValue);
}
else
{
//Decodes data, dont change
$body = json_decode($param, true);
$recieved = $body["data"];
//Gets the result of a query
$result = $dao->getResults($recieved);
}
$dao->closeConnection();
//Return the result of the query
ob_clean();
echo json_encode("param" .$param);
echo json_encode("body" .$body);
echo json_encode("recieved" .$recieved);
echo json_encode("result" .$result);
exit();
}
?>
output for the above echo statements:
"paramgetResults""body""recieved""result"
MySQLDao.php - this file holds the query result that I want to pass to my js
<?php
error_reporting(E_ALL); ini_set('display_errors', 1);
//Class for holding queries
class MySQLDao
{
var $dbhost = null;
var $dbuser = null;
var $dbpass = null;
var $mysqli = null;
var $dbname = null;
var $result = null;
//constructor
function __construct()
{
$this->dbhost = Conn::$dbhost;
$this->dbuser = Conn::$dbuser;
$this->dbpass = Conn::$dbpass;
$this->dbname = Conn::$dbname;
}
//Attempt a connection to the database
public function openConnection()
{
//Try and connect to the database
$this->mysqli = new mysqli($this->dbhost, $this->dbuser, $this->dbpass, $this->dbname);
//If the connection threw an error, report it
if (mysqli_connect_errno())
{
return false;
}
else
{
return true;
}
}
//Get method for retrieving the database conection
public function getConnection()
{
return $this->mysqli;
}
//Close the connection to the database
public function closeConnection()
{
//If there is a connection to the database then close it
if ($this->mysqli != null)
$this->mysqli->close();
}
//-----------------------------------QUERY METHODS-------------------------------------
public function getResults()
{
$sql = "SELECT room.room_description FROM room WHERE room.room_id = 1";
$result = $this->mysqli->query($sql);
//if (mysql_num_rows($result) == 1) {
// $obj = mysql_fetch_object($result, 'obResults');
// echo($obj);
// return $obj;
//}
echo json_encode($result);
//echo($result);
//return false;
}
}
?>
My AJAX code in my js file:
$.ajax ({
type: "GET",
datatype: "application/json",
url: "BaseClass.php",
data: { action : 'getResults' },
//error: function(err){console.log(err)},
success: function(output) {
console.log(output);
//alert(output);
}
//error, function(err){console.log(err)}
});
Any help is appreciated thanks!

Variable getting via Ajax is empty ( Phonegap-Ajax-Json-PHP-MySQL )

I created an android application using Phonegap. I made an account in 000webhost and I've added my PHP files on the server. In the phpMyAdmin, I've created my database.
Right, now I tried to connect my project with the online database and insert or check some data in it.
PROBLEM:
When I run the application in my mobile phone i get this alert from the success: ... part of code in ajax :
There is no such username.
(my PHP had in comments all the echo, except the: echo json_encode)
When I added this line (var_dump($_POST);) right after i am getting the $usernamefrom ajax in the PHP and run my app, I saw this alert: array(1){ [\"username\"]=> string(2) \"hi"\" }
When I added these lines: if (empty($username)) { echo '...' } , after I run my app, I saw that in the alert inside the error: ... part of the ajax, it is printed the echo that is inside this if. So, the $username is empty for sure.
This is my JavaScript file: (I get correctly for sure all the values from html so Focus on the two Ajax parts of code)

function onDeviceReady() {

$topost = file_get_contents('php://input');
$thedata = json_decode($topost, true);
$username = $thedata['username'];
//var_dump($_POST);
//if (empty($username)) {
// echo 'The username is either 0, empty, or not set at all';
//}
$sql = "SELECT COUNT(*) as Count FROM `user` WHERE `username`='$username'";
$result= mysql_query($sql, $con);
$rows = mysql_fetch_array($result);
$count = $rows['Count'];
if (!$result) {
die('Error: ' . mysql_error());
//$response_array['status'] = 'error';
//echo json_encode($response_array);
}
else {
if ($count == 0) {
echo json_encode(array('status' => 'success','message'=> 'There is no such username'));
//$response_array['status'] = 'success';
//echo json_encode($response_array);
}
else
{
echo json_encode(array('status' => 'error','message'=> 'The username already exists'));
//$response_array['status'] = 'error';
//echo json_encode($response_array);
}
}
mysql_close($con);
?>
And this is the PHP file in which I tried to insert the new entry in my database ( my credentials are for sure correct):
<?php
header('Content-type: application/json');
header('Access-Control-Allow-Origin: *');
//require_once('database_config.php');
$server = "mys****.000webhost.com";
$database = "a***37_guideme";
$username = "a***37_guideme";
$password = "******";
$con = mysql_connect($server, $username, $password);
// if($con) { //echo "Connected to database!"; }
// else { //echo "Could not connect!"; }
mysql_select_db($database, $con);
$topost = file_get_contents('php://input');
$thedata = json_decode($topost, true);
$username = $thedata['username'];
$password = $thedata['password'];
$email = $thedata['email'];
$gender = $thedata['gender'];
$age = $thedata['age'];
$about_you = $thedata['about_you'];
$sql = "INSERT INTO user (username, password, email, gender, age, about_you) ";
$sql .= "VALUES ('$username', '$password', '$email', '$gender', '$age', '$about_you')";
if (!mysql_query($sql, $con)) {
die('Error: ' . mysql_error());
// $response_array['status'] = 'error';
// echo json_encode($response_array);
}
else {
echo json_encode(array('status' => 'success','message'=> 'No problem'));
// $response_array['status'] = 'success';
// echo json_encode($response_array);
}
mysql_close($con);
?>

My problem solved by changing the way I get the data in my PHP to -> $user = $_POST['username']; instead of the way with Json (json_decode e.t.c.).

Undefined index errors - How do I set the last amount after discount?

I made a coupon code system for the admin to create new coupons. On the form, I need to calculate the last amount to be paid after the discount. I wrote the
if(!empty($discountCode)) {
$amount = ($unitCost - $unitCost * $couponDiscount / 100);
}
before adding the shipping costs and processing the payment. I'm not sure if it's correct...
I'm getting undefined index errors for $email - $qty - $cardName - $cardAddress1 - $cardAddress2 - $cardCity - $cardState - $cardZipcode - $shippingMethod - $product - $token - $couponDiscount, weird but not for $unitCost, $intRate or $domRate.
How can I fix this?
This is my form preorder.php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
// Stores errors:
$errors = array();
// Need a payment token:
if (isset($_POST['stripeToken'])) {
$token = $_POST['stripeToken'];
// Check for a duplicate submission, just in case:
// Uses sessions
if (isset($_SESSION['token']) && ($_SESSION['token'] == $token)) {
$errors['token'] = 'You have apparently resubmitted the form. Please do not do that.';
} else { // New submission.
$_SESSION['token'] = $token;
}
} else {
$errors['token'] = 'The order cannot be processed. Please make sure you have JavaScript enabled and try again.';
}
$unitCost = 6995;
$intRate = 1500;
$domRate = 500;
//print_r($_POST);
$email = $_POST['email'];
$qty = $_POST['qty'];
$cardName = $_POST['card-name'];
$cardAddress1 = $_POST['address'];
$cardAddress2 = $_POST['address2'];
$cardCity = $_POST['city'];
$cardState = $_POST['state'];
$cardZipcode = $_POST['zipcode'];
$shippingMethod = $_POST['shipping-method'];
$product = $_POST['productColor'];
$token = $_POST['stripeToken'];
$couponDiscount = $_POST['couponDiscount'];
if(!empty($discountCode)) {
$amount = ($unitCost - $unitCost * $couponDiscount / 100);
}
if($shippingMethod == 'International') :
$amount = $qty * ($intRate + $unitCost);
$description = ''.$qty.' - products(s) in '.$product.'(+International Shipping)';
else:
$amount = $qty * ($domRate + $unitCost);
$description = ''.$qty.' - products(s) in '.$product.'(+Domestic Shipping)';
endif;
// Charge the order:
$charge = Stripe_Charge::create(array(
"amount" => $amount, // amount in cents, again
"currency" => "usd",
"description" => $description,
"customer" => $customer->id
));
// Check that it was paid:
if ($charge->paid == true) {
$amountReadable = $amount / 100; // to add in decimal points
echo '<div class="alert alert-success">Your card was successfully billed for $'.$amountReadable.'</div>';
$status = "paid";
$tracking_num = "";
The form submission is done along with the coupon validation inside preorder.js, which is working well and checking the code correctly :
// Watch for the document to be ready:
$(document).ready(function() {
// Watch for a form submission:
$("#preorder").submit(function(event) {
// Flag variable:
var error = false;
// disable the submit button to prevent repeated clicks:
$('#submitBtn').attr("disabled", "disabled");
// Check for errors:
if (!error) {
Stripe.card.createToken({
number: $('.card-number').val(),
cvc: $('.card-cvc').val(),
exp_month: $('.card-expiry-month').val(),
exp_year: $('.card-expiry-year').val()
}, stripeResponseHandler);
}
// Prevent the form from submitting:
return false;
}); // Form submission
//Coupon code validation
$("#coupon_code").keyup(function(){
var value = $(this).val();
var data = {
code:value,
validateCouponCode:true
}
$.post("core.php",data,function(response){
//Since the response will be json_encode'd JSON string we parse it here
var callback = JSON.parse(response);
if(callback.status){
$("#couponStatus").html(" <span style='color:green'>Coupon is valid =) "+callback.discount_rate+"% discount</span> ");
}else{
$("#couponStatus").html(" <span style='color:red'>Coupon is not valid</span> ");
}
})
})
//Coupon Code validation END
}); // Document ready.
// Function handles the Stripe response:
function stripeResponseHandler(status, response) {
// Check for an error:
if (response.error) {
reportError(response.error.message);
} else { // No errors, submit the form:
var f = $("#preorder");
// Token contains id, last4, and card type:
var token = response['id'];
// Insert the token into the form so it gets submitted to the server
f.append("<input type='hidden' name='stripeToken' value='" + token + "' />");
// Submit the form:
f.get(0).submit();
}
} // End of stripeResponseHandler() function.
Here is the core.php:
//For ajax requests create an empty respond object
$respond = new stdClass();
$respond->status = false;
//END
$conn = mysql_connect("localhost",DB_USER,DB_PASSWORD);
mysql_select_db(DB_NAME);
//Execute the query
$foo = mysql_query("SELECT * FROM coupons WHERE expire > NOW() OR expire IS NULL OR expire = '0000-00-00 00:00:00'");
//Create an empty array
$rows = array();
while ($a=mysql_fetch_assoc($foo)) {
//Assign the rows fetched from query to the array
$rows[] = $a;
}
//Turn the array into an array of objects
$coupons = json_decode(json_encode($rows));
if(#$_POST["validateCouponCode"]){
foreach ($coupons as $coupon) {
if($coupon->coupon_code == $_POST["code"]){
//Coupon found
$respond->status = true;
//Additional instances to the respond object
$respond->discount_rate = $coupon->coupon_discount;
}
}
echo json_encode($respond);
}

After hours of practice on this, I ended up finding the solution and it's working.
Thanks for everyone for their suggestions.
Still open to any kind of advice to improve the code.
// Check for a form submission:
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
// Stores errors:
$errors = array();
// Need a payment token:
if (isset($_POST['stripeToken'])) {
$token = $_POST['stripeToken'];
// Check for a duplicate submission, just in case:
// Uses sessions, you could use a cookie instead.
if (isset($_SESSION['token']) && ($_SESSION['token'] == $token)) {
$errors['token'] = 'You have apparently resubmitted the form. Please do not do that.';
} else { // New submission.
$_SESSION['token'] = $token;
}
} else {
$errors['token'] = 'The order cannot be processed. Please make sure you have JavaScript enabled and try again.';
}
$unitCost = 4995;
$intRate = 1500;
$domRate = 500;
//print_r($_POST);
$email = $_POST['email'];
$qty = $_POST['qty'];
$cardName = $_POST['card-name'];
$cardAddress1 = $_POST['address'];
$cardAddress2 = $_POST['address2'];
$cardCity = $_POST['city'];
$cardState = $_POST['state'];
$cardZipcode = $_POST['zipcode'];
$shippingMethod = $_POST['shipping-method'];
$product = $_POST['kloqeColor'];
$token = $_POST['stripeToken'];
$couponDiscount = '';
$sql = "SELECT * FROM `------`.`coupons` WHERE `coupon_code` = '" .addslashes($_POST['coupon-code']) . "'";
//echo $sql;
$query = $connectAdmin->Query($sql);
if($query->num_rows > 0) {
$results = $query->fetch_array(MYSQLI_ASSOC);
$couponDiscount = $results['coupon_discount'];
}
//echo '<pre>' . print_r($_POST, true) . '</pre>';
$amount = $unitCost;
if(!empty($couponDiscount)) {
//$amount = ($unitCost - $unitCost * $couponDiscount / 100);
//echo 'Discount not empty<br>';
$amount = $unitCost * ((100-$couponDiscount) / 100);
}
//echo $amount . '<br>';

Can you please add your html of the form? You didn't list stripeToken as undefined index and this your if condition. So the variables $unitCost, $intRate or $domRate can be defined since you are assigning numbers. The question is, why stripeToken is defined but not the other indexes. Probably there is a problem with the form and its fields?
