Show posts descending from newest to oldest

Hi guys, i am currently making a website for a customer. And he want's to show all posts he's making from newest to oldest. And i thought peace of cake! Well.. I ran into some problems. I doesn't show anything at all. I tried doing the same thing as i did in my comment section where again, it's showing the newest and the older ones down.

This is my code: <?php $query = "SELECT * FROM posts"; $query = "ORDER BY post_author DESC "; $all_posts_query = mysqli_query($connection, $query);

            while($row = mysqli_fetch_assoc($all_posts_query)) {
            $post_id = $row['post_id'];
            $post_title = $row['post_title'];
            $post_author = $row['post_author'];
            $post_date = $row['post_date'];
            $post_image = $row['post_image'];

?> Hope you can help me out :)

Hi Mike,

Your query needs a space between it this is probably reason why its not working. Plus am sure its pulling the $query variable as u have not concatenated it. Try this:

<?php 
$query = "SELECT * FROM posts"; 
$query . = "ORDER BY post_author DESC "; 
?>

or

<?php 
$query = "SELECT * FROM posts ORDER BY post_author DESC "; 
?>

Apologize the first one should have a space on it like so :

<?php 
$query = "SELECT * FROM posts"; 
$query . = " ORDER BY post_author DESC "; 
?>

I just notice you ordering by author, would you not order by post_date or post_id? Or is there more then one author?

Well Peter i added your code like

$query = "SELECT * FROM posts"; $query . = " ORDER BY post_date DESC ";

And then it's giving me an HTTP ERROR 500 why?
