Getting a couple of errors and can't for the life of me see where I am falling down. Below is the functions file
<?php
include('config.php');
function getAllPosts()
{
try {
$dbh = new PDO(DB_HOST, DB_USER, DB_PASS);
} catch (PDOException $e) {
echo $e->getMessage();
}
$stmt = $dbh->prepare('SELECT id, title, content FROM posts ORDER BY created_at DESC');
$stmt->execute();
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);
return $results;
}
function getSinglePost($id)
{
try {
$dbh = new PDO(DB_HOST, DB_USER, DB_PASS);
} catch (PDOException $e) {
echo $e->getMessage();
}
$stmt = $dbh->prepare('SELECT title, content FROM posts WHERE id = ?');
$bindings = array($id);
$stmt->execute($bindings);
$result = $stmt->fetch(PDO::FETCH_ASSOC);
return $result;
}
?>
Also figured I should include the page that I am running to generate the error
<?php include('system/functions.php'); ?>
<html>
<head>
<title>Create A New Post | My First Blog</title>
<link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
<div id="form">
<?php if (isset($_GET['id'])){ ?>
<h2>Single Post:</h2>
<?php $post = getSinglePost($_GET['id']); ?>
<?php print_r($post); ?>
<?php } ?>
<fieldset>
</fieldset>
</div>
</body>
</html>
Any help much appreciated these are the errors in full.

Should include config file too
<?php
define('DB_HOST','mysql:host=localhost;dbname=blog');
define('DB_USER','root');
define('DB_PASS','');
?>

The constants you are using for Host, User and Password haven't been defined yet. There's probably something wrong with your config.php.

that means DB_HOST is not defined or DB_HOST is not accessible in the current context.
Try place these varibles in the script at the begining instead of include('config.php');
define('DB_HOST','mysql:host=localhost;dbname=blog');
define('DB_USER','root');
define('DB_PASS','');
