In this part of the code, both the score table and the profile page display everything I want, however, it is displaying EVERYBODIES details like

First Name Surname Email Category Username, However, I want it so that when the user is logged in they can only see THEIR OWN details


This is score.php

ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);

<!doctype html>
<html lang="en">
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <meta name="description" content="">
    <meta name="author" content="">
    <link rel="icon" href="../../../../favicon.ico">

// Check connection
if (mysqli_connect_errno())
echo "Failed to connect to MySQL: " . mysqli_connect_error();

$result = mysqli_query($con,"SELECT * FROM Score where 'Username' LIKE _['Username']");

echo "<table border='1'>

while($row = mysqli_fetch_array($result))
echo "<tr>";
echo "<td>" . $row['ID'] . "</td>";
echo "<td>" . $row['Username'] . "</td>";
echo "<td>" . $row['Score'] . "</td>";
echo "<td>" . $row['Gamedate'] . "</td>";
echo "<td>" . $row['QuizTitle'] . "</td>";
echo "</tr>";
echo "</table>";


this is profile.php

$result = mysqli_query($conn,"SELECT *FROM Users ");
while($row = mysqli_fetch_array($result))
       echo "<br />Your <b><i>Profile</i></b> is as follows:<br />";
        echo "<b>First name:</b> ". $row['FirstName'];
        echo "<br /><b>Last name:</b> ".$row['Surname'];
        echo "<br /><b>Email:</b> ".$row['Email'];
        echo "<br /><b>Year:</b> ".$row['Username'];
        echo "<br /><b>Date created :</b> ".$row['Date_Creation'];

How do you know which user is logged in? You have called session_start() but I see no references to any $_SESSION variables.


You should be storing the ID of the user on login then using that id in your queries. (... WHERE ID = $_SESSION['userid'] ) or, better yet, use a prepared query passing the id as a parameter.


You will be expecting only a single profile result so why have the while() loop? A single fetch is all you need.



SELECT * FROM Score where 'Username' LIKE _['Username']

The first mention of username in that query is a column name and should NOT be in quotes. Your syntax following LIKE is also wrong.


Don't use a nastyfrisk (SELECT * ) in your queries - specify the columns you need.


As for your error messages - if your $result contains a boolean (false) value then the query didn't work.
