You cannot call the header function after any output is sent. Visit http://www.w3schools.com/php/func_http_header.asp
<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<title>MyCloud-Login</title>
I seem to remember even blank lines causing issues with this as well. Move the top piece and get rid of blank lines and try again. There may be other issues but that is one of them.

Uber api oauth2 error: No redirect URI with code is provided

I'm following the uber ouath2 guide on this link.
I also have a registered uber app with an app id, client id, client secret, server token and a redirect URI:
http://localhost:8084/testapp
However, when I invoke https://login.uber.com/oauth/v2/authorize?client_id=[my_client_id]&response_type=code&redirect_uri=http://localhost:8084/testapp, instead of receiving a link with a token code (specified as a paremeter), I'm receiving the next html content:

I have searched for this kind of issue and also I have readed a lot of posts about uber api and oauth with no effective solutions.
What I'm doing wrong?
Thanks in advance for your help.

Are you saying that instead of a web page loading when you click that link in a browser, you're getting back a raw HTML response, or are you saying that you're making a GET request to that URL in some way other than opening it in a browser?

I'm responding to myself (partially), I hope this could help others.
According with Uber ouath2 guide, you must to explicitly display to your users a page where they must to interact putting their email account and password. When they do clic in "Login", they are redirected to an authorization page and, finally, when they accept the information access agreement, uber redirect to your specified uri, putting at the end, the authorization code.
However, my scenario is different and maybe I need to put another question, since what I need is to access to my own information using a registered uber app on my own uber account and, I need to automate the oauth2 validation process. I mean, this need to be an automated process where I will not there to interact with the uber agreement information statements: I need in an automated way, send my client id and all required data and retrieve an authorization code.

PHP variable auto update failure

I have this code that I want that $X to be updated in the form, so when I press the +1 button it just keep going adding 1 to the form
<html>
<head>
<title>7mada</title>
</head>
<body>
<?php $X = 7 ;?>
<form method="POST" >
<table border="0" width="60%">
<tr> <td width ="30%"> Number: </td><td><input type="test" name="newname" value="<?php echo $X ;?>" readonly></td></tr>
</table>
<input name="save" type="submit" value="+1"/>
</form>
<?php
if($_POST){
if($_POST['save'] == "+1"){
$_POST['newname']++;
echo $_POST['newname'];
$X = $_POST['newname'];
}
}else{echo "say smth";}
?>
</body>
</html>
thanks.

Hey Samy this is the answer for your question :D :D
It completely ignores HTML output, therefore PHP can't interact with events that should be javascript.
you have two options:
1-Do it in Javascript, Live
2-Do it in PHP, requires refresh
If you want to do it in JavaScript, you'd do this:
<html>
<body>
<button onclick="add()">Add</button>
<div id="showIt"><script type="text/javascript">document.write(x);</script></div>
</body>
<head>
<title></title>
<script type="text/javascript">
var x = 0;
function add() {
x++;
document.getElementById('showIt').innerHTML = x;
}
</script>
</head>
</html>
or in PHP:
<?php
session_start();
$_SESSION['x'] = ((isset($_SESSION['x'])) ? $_SESSION['x'] : 0);
if(isset($_GET['add'])){
$_SESSION['x']++;
}
?>
<html>
<head>
<title></title>
</head>
<body>
<form action="<? echo $_SERVER['PHP_SELF']; ?>" method="get">
<input type="submit" name="add" value="add" />
</form>
<?php
echo $_SESSION['x'];
?>
</body>
</html>
I hope this helps you,

Empty Field Validation for Editing Stored Record Not Working

I have connected to my database to edit stored records and I’ve used a variable for the errors.
When I try to submit with empty fields it redirects and displays the changes have been saved message instead of displaying empty fields message
I’m sure there is something wrong with the structure of my loop and I am putting something in the wrong place?
<?php
//session_start();
// connect to the database
include('connect.php');
$message = $_GET['message'];
// check if the form has been submitted then process it
if (isset($_POST['submit']))
{
// Get data from table
//set the id manually for test purposes
$id = "429";
$forename = $_POST['forename'];
$surname = $_POST['surname'];
$username = $_POST['username'];
$email = $_POST['email'];
$password = $_POST['password'];
// check for empty fields and display error message
if (empty($forename) &&!empty($surname) &&!empty($username) &&!empty ($password) &&!empty ($email))
{
$message = "Please enter data in all fields" ;
header("Location: edit.php?message=$message");
}
else
{
// save the data to the table
mysql_query("UPDATE registration SET forename='$forename', surname='$surname', username='$username', email='$email', password='$password' WHERE id='$id'")
or die(mysql_error());
}
// redirecr and display message
$message = "Your changes have been saved";
header("Location: edit.php?message=$message");
exit;
}
$id=429;// this line could have been $id=$_SESSION['id'];
$result = mysql_query("SELECT * FROM registration WHERE id=$id LIMIT 1")
or die(mysql_error());
$row = mysql_fetch_array($result);
// check that the 'id' matches up with a row in the databse
if($row)
{
// get data from the table
$forename = $row['forename'];
$surname = $row['surname'];
$username = $row['username'];
$email = $row['email'];
$password = $row['password'];
}
?>

Try This

$message = "Please enter data in all fields" ;
header("Location: edit.php?message=$message");
}
