Flubber 2.0 is built from ground up, while keeping the same principles of 1.0

##Create project

Download Flubber from https://github.com/madhugb/flubber/archive/master.zip

cd ~/

wget https://github.com/madhugb/flubber/archive/master.zip

After extracting the zip file, move Flubber folder to

cd ~/flubber

mv Flubber ~/.Flubber

To start working you need to run this

php ~/.Flubber/setup.php --path=/var/www/example --url=example.com

It creates a folder structure for you to in /var/www/example.

Note : This needs you to have full write access to the path of the project and Flubber codebase

##Folder structure

To configure Flubber application you need to provide the following

SITEURL - url without protocol (i.e http:// , https:// )


HAS_SSL - false | true

SITEADMIN - "admin@example.com"

TIMEZONE - "Asia/Kolkata"

SESSION_NAME - "__ses"

SESSION_EXPIRY - 3600 // in seconds

SESSION_IDLE - 3600 // in seconds

SESSION_AUTO_RENEW - true | false

LOGIN_URI - path to login url if exists


TOKEN_SECRET - A long random string for csrf token secret make sure to put a long random string.

TOKEN_EXPIRY - 300 // in seconds

DBTYPE - "mysql" // for now only mysql is supported

DBHOST - "localhost"

DBUSER - "dbusername"

DBPASS - "dbpassword"

DBNAME - "databasename"


 server {

    listen 80;

    server_name flubber.co;

    root /var/www/example/public/;

    index index.php index.html;

    location / {

        try_files $uri $uri/ /index.php?$args;


    location ~ \.php$ {

        try_files $uri =404;

        include /etc/nginx/fastcgi_params;

        fastcgi_pass unix:/var/run/php5-fpm.sock;

        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

        fastcgi_index index.php;

        proxy_buffer_size   128k;

        proxy_buffers   4 256k;

        proxy_busy_buffers_size   256k;




/config/urls.php contains all url patterns for the application

it must contain a variable $urls as an array.

each index of url

$urls = array(


		"<regex_pattern>", "HandlerName"




For example:


	"/^login$/", "LoginHandler"


which translates to if the url is http://example.com/login.

the request is passed to LoginHandler.


	"/^user\/(?P<user_id>[0-9]+)$", "UserHandler"

which translates to if the url is http://example.com/user/123

the request is passed to UserHandler with an argument $user_id = "123"


You will be spending more time here; as your application logic is written here.

take a look at a sample UserHandler handler



use Flubber\BaseHandler as BaseHandler;

class UserHandler extends BaseHandler {

	function __construct() {


				"auth" => array( "get", "post"),

				"csrf_check" => false

	function get() {


		// Composre your response here

		$response = array( "message" => "hello");

		// Show `home` template

		$this->show_page("home", $response);

	function post() {

		$data = $this->request->data["post"];

		// send the same data back



Let us see how this handler work

####Class Structure

Every handler must be extended to BaseHandler Apart from extending we must call the parent constructor in the constructor of the handler.

function __construct() {

$config = array();



There are some things you can configure per handler those should be passed to parent constructor in an array.

Configurations are as below

  1. auth - this sets the authentication check for "get", "post", "put" requests

     $config["auth"] = array("post","put");

    which checks for authentication for post and put requests. If not authenticated it will redirect to login page for any other type of requests authentication will not be ckecked.

  2. csrf_check - this boolean key enables or disables the checks for csrf token

    if the value is true then it checks csrf token in the following places

    a. X-Csrf-Token header

    b. _csrf in post or put data

####Accessing request data

To handle different request methods you need to have function by the name of request methods. Allowed methods are GET, POST, PUT, DELETE,OPTIONS.

To handle GET request you need to have function get(){ } in the handler (note that the function names are in lowercase).

In every handler you can access $this->request object which contains all request data.

  1. $this->request->get("key") - value of GET argument key.

  2. $this->request->post("key") - value of POST data key.

Or you can access $this->request->data directly which has


	"get" => array(

		"get_data_key_1" => "get_data_value_1"


	"post" => array(

		"post_data_key_1" => "post_data_value_1"


	"put" => array(),

	"files" => array()

There is a special params key in requests.

This can be accessed from $this->request->params will get

all the values from url path based on named regex match.

For example "/^user/(?P<user_id>[0-9]+)$" will match http://example.com/user/123

and $this->request->params["user_id"] contains value 123

also you can access this from function argument like below

function get($user_id=false) {
	// here $user_id will contain 123


####Response Handling

You can respond by showing a template file or sending a json response.

to show a template page

$this->show_page("template_name", $data);

where $data is array of data to be used in template

to send a json response


where $data is array which can be json encoded.

find more detail about Templates below


To access request headers


To respond with headers the below functions will help

$this->set_status(200); // sets status to "200 OK"

$this->headers["X-My-Custom-Header"] = "Some Value"; // will sets the header

####Session Handling

Flubber Session is identified based on Cookie. Cookie name can be changed from config SESSION_NAME

To start a session


One must set a session identifier uid after starting session

$this->session->set("uid", "<unique id for the user>");

To destroy a session



Flubber uses Twig templating library for rendring html templates

although this is bigger (~500Kb) than actual framework size (~200Kb). It made

lot of sense to just include this instead of writing one more. However someday

we will have a lighter solution.

Flubber uses a wrapper method to Twig the APIs are listed below

As we have shown before to show a template page you can call

$this->show_page("<template file name>", $response);

Read Twig documentation for more details


language files are located in config/locale/ directory of your app

each language should have a dedicated ini file, which should contain all the strings

for example :

hello="Hello World!"

To set a locale for your handler in constructor

function __construct() {


	// Get locale from session / cookie /  db or hard code
	//  $mylocale = "en";
	$this->locale = $mylocale;
