I am perplexed. I have done this before and know this should work but cannot understand why the function is not found. Perhaps a second set of eyes will uncover the mystery.

EDIT:
Please note the commented within the PHP code. That does not work either.
You are calling the function:
<script type='text/javascript'>stopUpload(1);</script>
But before you call it you need to load your JS:
<script src='./pathto/something.js'></script>; <!-- something.js declares stopUpload -->
<script type='text/javascript'>stopUpload(1);</script>

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

My AJAX code in my js file:
$.ajax ({

Any help is appreciated thanks!
I'm not sure why my db isn't connecting. I'm basically trying to produce a website in javascript, and I'm using an AJAX to call a method in a php file. This method is a query so I can get results of this query into some of my js components. Can anyone help please? I've been stuck for ages! Any help is appreciated.
Part of my javascript file:
function callPHP() {
$.ajax ({
type: "GET",
datatype: "application/json",

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({
type: "POST",
dataType : "json",
url: "flip-process.php",
data: dataString,
cache: true,
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;
});
});
PHP Script
<?php

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 $deduct before the if block.
I created an android application using Phonegap. I made an account in 000webhost and I've added my PHP files on the server. In the phpMyAdmin, I've created my database.
Right, now I tried to connect my project with the online database and insert or check some data in it.
PROBLEM:
When I run the application in my mobile phone i get this alert from the success: ... part of code in ajax :
There is no such username.
(my PHP had in comments all the echo, except the: echo json_encode)
When I added this line (var_dump($_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)

if (strong_flag_user == 1 && strong_flag_pass == 1 && strong_flag_email == 1){
//add to db
register_db(email.value, password.value, username.value, gender, about_you, age);
}
}
function register_db(em, pass, user, gend, about, ag) {
$.ajax({
url: "http://www.guidemeforall.freeiz.com/phps/sign-up.php",
type: "POST",

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.).
