Setup single record MySQL and PHP - php

Question

How to set a single record to a user profile? For example username, password, email, and wallet. I need to show only date for each user login. This script shows wallet but first user id person and I need to show the user who is logged in.
HTML and PHP:
<?php
$con=mysqli_connect("mysql","root","pass","db");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result = mysqli_query($con,"SELECT wallet FROM users LIMIT 1");
echo "<table border='0'>
<tr>
<th>wallet</th>
</tr>";
while($record = mysqli_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $record['wallet'] . "</td>";
echo "</tr>";
}
echo "</table>";
mysqli_close($con);
?>

To answer you fully.
Start by updating your user table when your users log in by changing the status true or false depending on your implementation.
Also start a session
your code now becomes
<?php
session_start();
$con=mysqli_connect("mysql","root","pass","db");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
//Login logics
$res= mysqli_query($con,"SELECT * FROM users where username='user' and password ='pass'");
if($res)
{
$user = mysql_fetch_row($res);
//Keep track of the current logged in user
$_SESSION['user'] = $user['id'];
}
//Now your logic to get wallet or any other thing for the current logged in user
$currentUser = $_SESSION['user'];
$result = mysqli_query($con,"SELECT wallet FROM users where id=".$currentUser.");
echo "<table border='0'>
<tr>
<th>wallet</th>
</tr>";
$record = mysqli_fetch_row($result)
echo "<tr>";
echo "<td>" . $record['wallet'] . "</td>";
echo "</tr>";
echo "</table>";
mysqli_close($con);
?>
Hope this helps..
Work with the Edit you dont need the While loop since you are looking for just a record
