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)

This is my PHP file in which I check if the username already exists (Username = Primary Key):
<?php
header('Content-type: application/json');
header('Access-Control-Allow-Origin: *');
//require_once('../database_config.php');
$server = "my***.000webhost.com";
$database = "a1****37_guideme";
$username = "a1****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 = $thedata['username'];
//var_dump($_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.).

1) Why you are using variable jsonObj instead of response ?
2) Modify your if statement like this
if(response.success==1){
window.location.href="index.php";
}
window.location is not a function it is an object. Please change href property in window.location object to redirect to new url.
window.location.href = "./index.php";
Simple redirect to specific file
if(jsonObj.success==1)
{
window.location.href = "http://www.example.com/index.php";
}
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;

$this->dbhost = Conn::$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

{
return false;
}
else
{
return true;
}
}
//Get method for retrieving the database conection

{
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) {

Any help is appreciated thanks!

I have a script where I want to process form data using ajax. The script is returning the success message but not the error message. Have a look at the scripts below.
AJAX Script
$(document).ready(function() {
$("#submit").click(function() {
var dataString = {
flip: $("#flip").val(),
amount: $("#amount").val()
};
$.ajax({

beforeSend: function(){
$("#submit").hide();
$("#loading").show();
$(".message").hide();
},
success: function(json){
setTimeout(function(){
$(".message").html(json.status).fadeIn();
$('#mywallet').html('$' + json.deduct);
$("#submit").show();
$("#loading").hide();
},3000);
}
});
return false;
});
});

Here in the scripts above, when if($wallet < $amount) condition is false and else condition is executed, the scripts works fine and returns <div class='message-success'> as required. But, if if($wallet < $amount) condition is true then its not returning <div class='message-error'> and the loading image keeps on moving (as if waiting for the response) but does not receives any response in return. I am stuck since a few days on this but not being able to find any solution for the same. Please help.
I am not sure but I think in your php script $deduct has been declared inside the else block.
so when the script executes and if ($wallet < $amount) condition evaluates to true, then the else part is skipped and you directly return this:-
return echo json_encode(array(
'status' => $msg,
'deduct' => $deduct
));
so it might be the case that $deduct is not recognized. try executing by declaring the $deduct before the if block.
I have the following jQuery in my index.php file (www root):
$(document).ready(function() {
$('#loginForm').submit(function() {
var username = $("#username").val();
var password = $("#password").val();
$.post("php/login.php",
{
username: username,
password: password
},
function(data,status){
$("#loginstatus").html(data);
alert(data);
}
);
});
});
and the following php script in the folder php:
<?php
$username = isset($_POST["username"]) ? $_POST["username"] : '' ;
$password = isset($_POST["password"]) ? $_POST["password"] : '' ;
$dbhost = "localhost";
$dbuser = "s150314";
$dbpass = "password";
$dbname = "users";
$loginerror = "";
$conn = mysqli_connect($dbhost, $dbuser, $dbpass, $dbname);
$sqlu = "SELECT username FROM users WHERE username LIKE '$username' ";
$sqlp = "SELECT password FROM users WHERE password LIKE '$password' ";
$sqlfn = "SELECT FirstName,LastName FROM users WHERE username LIKE '$username' ";
$resultu = mysqli_query($conn, $sqlu) ;
$resultp = mysqli_query($conn, $sqlp) ;
$resultfn = mysqli_query($conn, $sqlfn) ;
if (mysqli_num_rows($resultu) > 0 && mysqli_num_rows($resultu) > 0 ) {
while($row = mysqli_fetch_assoc($resultfn)) {
$_SESSION["FirstName"] = $row["FirstName"];
}
echo "Success!";
header("Location: ../pages/redirect.php");
} else {
echo "Error!";
}
?>
However there is no change on the submission of the form. In theory I am supposed to be redirected to redirect.php... if I replace the php code back into index.php it works flawlessly.
Use window.location
<script>
$.post("php/login.php",
{
username: username,
password: password
},
cache:false,
success:function(data){
if(data.status == 'success'){
window.location.href="http:\\www.site_name.php/pages/redirect.php"";
}else if(data.status == 'error'){
alert(data);
}
}
</script>
PHP
<?
header('Content-type: application/json');
$SqlQuery = "SELECT FirstName,LastName,username FROM users WHERE username LIKE '$username' AND password LIKE '$password'";
$resultu = mysqli_query($conn, $SqlQuery) ;
if (mysqli_num_rows($resultu) > 0 && mysqli_num_rows($resultu) > 0 ) {
