error: Database not selected

Question

I'm stuck with this issue: No database selected. I roll over the same problems posted here, but after hours of reading I can't figure out why the database is not selected. I created a database job and a table job. I run the script with WAMP server. Sorry about the "everyday question." Please help!

<?php

// load Smarty library
require('C:/wamp/www/smarty-3.1.21/libs/Smarty.class.php');

$servername = "localhost";
$dbname = "job";

// Create connection
$conn = mysqli_connect($servername, $dbname);

// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}

$smarty = new Smarty;

$smarty->setTemplateDir('C:\wamp\www\app\templates');
$smarty->setCompileDir('C:\wamp\www\app\templates_c');
$smarty->setConfigDir('C:\wamp\www\app\configs');
$smarty->setCacheDir('C:\wamp\www\app\cache');


$rows = array();
$sql = "SELECT * FROM job";
$result = mysqli_query($conn, $sql);

if (!$result) {
    echo 'MySQL Error: ' . mysqli_error($conn);
    exit;
}

while ($row = mysqli_fetch_assoc($result)) {
    $rows[] = $row;
    }

$smarty->assign('output', $rows);
$smarty->display('result.tpl');

mysqli_close($conn);

?>

Those aren't the right parameters to mysqli_connect. You have to pass host, username, password, and then database name. You are passing only the host and the database name, so you are not connecting correctly.
