Bonjour,
j'ai l'erreur suivante :
Warning: PDO::query(): SQLSTATE[3D000]: Invalid catalog name: 1046 No database selected in C:\xampp\htdocs\Sites\functions\home.func.php on line 7

Fatal error: Call to a member function fetchObject() on a non-object in C:\xampp\htdocs\Sites\functions\home.func.php on line 11

alors que j'ai suivi le tuto a la letter.

voici mon code :

home.func.php :

<?php

function get_posts(){

global $db;

$req = $db->query("

SELECT * FROM posts

");

$results = array();

while($rows = $req->fetchObject()){
$results[] = $rows;
}
return $results;
}
?>

main-functions.php :

<?php

$dbhost = 'localhost';
$dbname = 'blog';
$dbuser = 'root';
$dbpswd = '';

try{
$db = new PDO('mysql:host='.$dbhost.';$dbname='.$dbname,$dbuser,$dbpswd, array(PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8', PDO::ATTR_ERRMODE => PDO::ERRMODE_WARNING));

}catch(PDOException $e){
die("une erreur est survenue lors de la connexion a la base de donnees");
}
?>
