msql_connect($hostname,$username,$password) or die ("<html><script>
language='Javascript'>alert('Unable to connect to database!.'),history.go(-1)</script></html>")
should have a semicolon.
Replace it with this:
msql_connect($hostname,$username,$password) or die ("<html><script>
language='Javascript'>alert('Unable to connect to database!.'),history.go(-1)</script></html>");

<?php
$hostname = "localhost";
$username = "";
$password = "";
$dbname = "thesis";
$usertable = "product";
$yourfield = "product_id";
$mysqli = new mysqli($hostname, $username, $password, $dbname);
/* check connection */
if ($mysqli->connect_errno) {
printf("Connect failed: %s\n", $mysqli->connect_error);
exit();
}
/* Select queries return a resultset */
if ($result = $mysqli->query("SELECT * FROM $usertable")) {
while ($row = mysql_fetch_array($result))
{
$name = $row["$yourfield"];
echo "Name: ".$name."</br>";
}
/* free result set */
$result->close();
}
$mysqli->close();
