I want to replace the null in my database with a 1 if my function returns true. I am not sure how to do it when it's for the session user.
In PHP should I use a 0 or a 1 for true?
This is the first part of my code that includes the session user and the return of the javascript function.
<?php
mysql_connect('localhost','user','pass');
mysql_select_db('db');
session_start();
$username=$_SESSION['username'];
if(!$username){
die("Please login");
}
else
{
$query="select *from users WHERE username='$username' ";
$run=mysql_query($query);
while($row=mysql_fetch_array($run)){
$admin=$row['username'];
}
}
?>
