php - Checking if two results are the same not working -

so i'm trying display message user of account. i'd go user profile /index.php?username=joe. if joe you'd have ability of post, i'd show post box. issue reason box shows if you're not joe. here's code

$stmt = $con->prepare("select username users username = :username"); $stmt->bindvalue(':username', $_get['username']); $stmt->execute(); $row = $stmt->fetch(); $username = $row['username'];  if (count($username) < 1){     echo "user not found"; }   echo $_session['user']; echo $username; ?> //issue has here somewhere  <?php if($_session['loggedin'] == true || $username == $_session['user']) : ?>         <form method="post" action="http://localhost:8888/post/p.php">             <input type="text" name="post" placeholder="post">             <input type="submit">         </form>  <?php else: ?> <!--display sign , in--> <p>sign in </p> <?php endif; ?> 

so echo $_session['user']; displays allen, while echo $username; displays joe. i'd assume form shouldn't show. ideas?

you using wrong operator. || means logical or.

<?php if($_session['loggedin'] == true || $username == $_session['user']) : ?> 

instead need logical and:

<?php if($_session['loggedin'] == true && $username == $_session['user']) : ?>
