== Installing Smarty
The tutorial on Smarty's official website are rather good, so let's just go through them:
Database example
I have created a simple database + Smarty example on mi-linux, here:
And here is the code for it:
The PHP files
The main file:
<?php
// Set-up Smarty folders and connect to db
require("setup_smarty.php");
require("connect_db.php");
// Get data
$sql = "SELECT FilmNumber, FilmName, FilmGenre, FilmDuration FROM Films";
$myresult = mysql_query($sql);
$total = mysql_num_rows($myresult);
// Put data in array
while ($row = mysql_fetch_assoc($myresult))
$results[] = $row;
// Assign data to template
$smarty->assign('total', $total);
$smarty->assign('results', $results);
// Display template
$smarty->display('db.tpl');
?>
As you can see it includes a couple of files:
- setup_smarty.php: Smarty set-up
- connect_db.php: connection to your database
<?php
// setup_smarty.php
// Include Smarty.class.php
require('libs/Smarty.class.php');
// Create Smarty object
$smarty = new Smarty();
// Set-up Smarty folders
$smarty->template_dir = 'templates';
$smarty->compile_dir = 'templates_c';
$smarty->cache_dir = 'cache';
$smarty->config_dir = 'configs';
?>
<?php
//connect_db.php
// Connect to db
$dbServer=mysql_connect("localhost","xxxx","xxxx");
if (!$dbServer) {echo "Failed to connect to MySQL"; exit; }
mysql_select_db("xxxx",$dbServer);
?>
The templates
The main template:
{include file="header.tpl" title="Smarty rocks!"}
<h1>Database example</h1>
<p>Displaying {$total} records :</p>
<table style="width:200px">
{section name=nr loop=$results}
<tr style="background-color:{cycle values="#eeeeee,#dddddd"}">
<td>{$results[nr].FilmName}</td>
<td>{$results[nr].FilmGenre}</td>
</tr>
{sectionelse}
<tr><td>No results found!</td></tr>
{/section}
<table>
{include file="footer.tpl"}
The header and footer (included above):
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>{$title|default:"no title"}</title>
</head>
<body>
</body> </html>
