Someone help me out Ive been working on this code for 4 hour

Someone help me out, I\'ve been working on this code for 4 hours.

Here\'s the scenario.

I am posting String data from an android app I am developing to an sql database.

I am able to \'echo\' all of the POST data from the PHP to the android app, so I am fairly confident that the java is solid.

But heres the thing that baffles me...

When I change the $POST[\"username\"] to \"andrewnguyen22\" it works fine...

Below I have posted my PHP and my Java. Please help

PHP CODE:

require \"conn.php\";
$username = $_POST[\"username\"];
$fullName = $_POST[\"fullName\"];
$age =$_POST[\"age\"];
$bio =$_POST[\"bio\"];
$year =$_POST[\"year\"];
$gender =$_POST[\"gender\"];
$location =$_POST[\"location\"];
$sql = \"UPDATE user_info SET fullName =\'$fullName\', bio=\'$bio\', age=\'$age\', gender=\'$gender\', location=\'$location\', year=\'$year\' WHERE username = \'$username\' \";
$do = mysqli_query($conn, $sql);
if(mysqli_affected_rows($conn) >0){
echo 0;
}
else{
   echo $username;
}  
?>

Android App Code Snippet:

So when the code fails. It displays my username correctly on my android emulator... (through the alert dialog if else on postexecute0

Solution

Hello,

You code seems to be fine. Instead of $POST[\"username\"] , could you please hard-code any username and try running the code again. OR, please use the keyword userid instead of username, and see if that works fine for you.

Hope this helps..
