Lets write our first littlefoot app!

First off, [Install]( LittlefootCMS.

LF path

After installation, before customizing anything, you should have a littlefoot folder in public_html and an lf folder inside that. LF is defined as /home/<user>/public_html/littlefoot/lf in /home/<user>/public_html/littlefoot/lf/system/bootstrap.php. You are welcome to move the installation around, just remember that LF points to that full path of that lf folder .

Hello World

Covers: Write an app. Attach it to the website. View it on the website.

1) Make a new folder at LF/apps/myfirstapp

2) Add an index.php to it with the following contents: Hello World

3) Go to the Dashboard and add myfirstapp to the navigation by clicking it under the App Gallery

4) Click your domain at the top of the admin to visit the front end and navigate to the new navigation item.

5) You should see 'Hello World' printed on the page.

That's your app! Now let's add an Admin section to it.


The index.php is included for client-side requests. But some aspects of apps such as their management interface would ideally not be accessible to the client. Instead we use a separate file at 'lf/apps/myfirstapp/admin.php'. Create this file and add the following content:

Hello Admin

To view this new file, log into the Littlefoot backend at '' (defualt user: "admin" pass: "pass"). You should see "myfirstapp" on the left navigation under Dashboard. All apps that have an admin.php are displayed here. Click any app to manage it. If you click 'myfirstapp', you should see "Hello Admin" displayed.

From this and the Hello World example, you can see where each index.php and admin.php file is processed and displayed. Now that you understand front-end vs back-end, lets do some PHP


In the previos examples, you learned the difference between [index.php] and [admin.php]. All we used was text, no PHP.

Throw some PHP in in your index.php. Try the following:

<h2>My App</h2>
<p><?php echo date('F j, Y'); ?></p>

or if you want to go pure PHP:


echo '<h2>MyApp</h2>';
echo '<p>';
echo date('F j, Y');
echo '</p>';

You can program an app without using any special littlefoot framework features.

But the Helpers and other classes like ORM do make some things easier.
