Hi I have used some code but I want it so when the name is NULL it is hidden, if this is possible please help.

Here is the code

    <p id="top"><strong>Welcome back <?php echo $_SESSION['name']; ?> [<a href="admin/logout.php">Logout</a>]<br/>Welcome To the homepage of The Journalist's</p>

    "<strong>Welcome back <?php echo $_SESSION['name']; ?> [<a href="admin/logout.php">Logout</a>]" 

to be hidden.

Thank you.

Update from your posted code:

For one, you are using $SESSION instead of $_SESSION. Second, you are setting $SESSION['name'] using a single equal sign, so the if condition would always fail because it is evaluating if (NULL). You need to use == or ===. Read up on comparison operators.

<?php
if (condition) {
?>
<div></div>
<?php
}
?>
