Answer 1

Before we address the line 7 issue, lets check other errors. In order to request a query to a MYSQL database, we need to create a connection:
$con = mysqli_connect("ip_address","user","password","database_name");
Once we have that connection, let us check if we can actually connect to the database:
if (!$con) {
die('Could not connect: ' . mysqli_error($con));
}
Appreciate that mysqli_error() function uses the connection. Now the query string:
$query3 = "SELECT id, username, bid FROM bids WHERE username = '$login_session'";
You are sending a query to look for a username called "$login_session" and it would most likely not find any match. To add strings from variables will be as follow:
$query3 = "SELECT id, username, bid FROM bids WHERE username = '" . $login_session . "'";
Now, for the error in line 7
result3 = mysql_query($con, $query3) OR die($mysql_error($con));
As you can see, both mysql function use the connection to check for errors. Try it and let me know if everything works fine.
Edit:
Terribly sorry my friend, I just forgot to put a little letter "i" on the line, also, I would like to show you my way to deal with the query result. First, the line as it should be:
$result3 = mysqli_query($con, $query3);
Notice the i after mysql. Now let us check whether we got some rows or not:
if (!$result3) {
die('Could not retrieve data: ' . mysqli_error($con));
} else {
while ($row = mysqli_fetch_array($result3)) {
//Show your results
}
}
