Blog/comments integration with login
Posted: Sat Apr 13, 2013 10:49 pm
Hi, I just finished the blog and comments tutorial and was wondering if there was a way to integrate the blog thing with the login. So everytime someone wants to post a status or a post, they don't need to post their name (or username). It'll automatically enter it into the database.
My code of what I have so far:
home.php
read_posts.php
My code of what I have so far:
home.php
<?php
include('core/init.inc.php');
if (isset($_POST['user'], $_POST['body'])){
add_post($_POST['user'], $_POST['body']);
header('Location: home.php');
die();
}
?>
