Display current logged in user's profile - php

Question

I've been working on code for student registration. I finished coding for my log in.
What I'm having a problem with is showing the user's profile: student fname, lname, program, gender and year level in textboxes. I'm using MySQL as my back end.
My code is like this:
<?php
// connects to the database
$mysqli = new mysqli("localhost", "root", "");
$query = 'SELECT fname, lname, program, gender, year FROM students WHERE fname = '.$_SESSION['myusername'];
$mysqli->query($query);
echo "<div align=\"center\">";
echo "<br />Your <b><i>Profile</i></b> is as follows:<br />";
echo "<b>First name:</b> ". $_POST['fname'];
echo "<br /><b>Last name:</b> ".$_POST['lname'];
echo "<br /><b>Program:</b> ".$_POST['program'];
echo "<br /><b>Year:</b> ".$_POST['year'];
echo "<br /><b>Gender:</b> ".$_POST['gender'];
echo "</div>";
?>
This is my code for mainstudent.php and checklogin.php.

Answer 1

Here you go:
<?php
session_start();
// connects to the database
$mysqli = new mysqli("localhost", "root", "");
$query = "SELECT fname, lname, program, gender, year FROM students WHERE fname = '".$_SESSION['myusername']."'";
if($result = $mysqli->query($query))
{
while($row = $result->fetch_assoc())
{
echo "<div align=\"center\">";
echo "<br />Your <b><i>Profile</i></b> is as follows:<br />";
echo "<b>First name:</b> ". $row['fname'];
echo "<br /><b>Last name:</b> ".$row['lname'];
echo "<br /><b>Program:</b> ".$row['program'];
echo "<br /><b>Year:</b> ".$row['year'];
echo "<br /><b>Gender:</b> ".$row['gender'];
echo "</div>"
}
$result->free();
}
else
{
echo "No results found";
}
?>
