SLIM EXAMPLES

23

24

<?php

require 'Slim/Slim.php';

$app = new Slim();

$app->get('/', function() { echo 'Hello World from base route.'; });

$app->run();

BASE ROUTING

25

<?php


$app = new Slim();


//param "name" is required$app->get('/hello_to/:name', function($name) { echo 'Hello World to ' . $name;});

$app->run();

REQUIRED PARAM

26

<?php


$app = new Slim();


//when using optional params, you have to define default value for function param$app->get('/hello_to(/:name)', function($name = null) { if ($name === null) { $name = 'John Doe'; } echo 'Hello World to ' . $name;});

$app->run();

OPTIONAL PARAM

27

<?php


$app = new Slim();

$app->get('/', function() use ($app) { echo 'Hello World from base route. '; $url = $app->urlFor('hello', array('name' => 'Jimmy')); //create link for route $link = sprintf('<a href="%s">%s</a>', $url, $url); echo 'Oh, link to hello page for Jimmy is ' . $link;});

$app->get('/hello_to(/:name)', function($name = null) { if ($name === null) { $name = 'John Doe'; } echo 'Hello World to ' . $name;})->name('hello'); //using name for route

$app->run();

NAMED ROUTES

28

<?php


$app = new Slim();

$app->get('/', function() use ($app) { echo 'Hello World from base route. '; $url = $app->urlFor('hello', array('name' => 'Jimmy')); $link = sprintf('<a href="%s">%s</a>', $url, $url); echo 'Oh, link to hello page for Jimmy is ' . $link;});

$app->get('/hello_to(/:name)', function($name = null) { if ($name === null) { $name = 'John Doe'; } echo 'Hello World to ' . $name;})->name('hello') ->conditions(array('name' => '[A-Za-z]+')); //use only letters as param 'name'

$app->run();

ROUTE CONDITIONS

29

<?php


$app = new Slim();

/* ... */

$app->get('/hello_to(/:name)', function($name = null) { if ($name === null) { $name = 'John Doe'; } echo 'Hello World to ' . $name;})->name('hello') ->conditions(array('name' => '[A-Za-z]+'));

//redirect to default hello page$app->get('/redirect', function() use ($app) { $app->redirect($app->urlFor('hello'));});

$app->run();

REDIRECT

30

<?php


$app = new Slim();

/* ... */

$app->get('/hello_to(/:name)', function($name = null) { if ($name === null) { $name = 'John Doe'; } echo 'Hello World to ' . $name;})->name('hello') ->conditions(array('name' => '[A-Za-z]+'));

//redirect to default hello page as 301, not 302 which is default$app->get('/redirect', function() use ($app) { $app->redirect($app->urlFor('hello'), 301);});

$app->run();

REDIRECT WITH STATUS

31

MIDDLEWARE

<?php


$app = new Slim();

$app->get('/', function() { //this will be executed before main callable echo "Hello, I'm middleware "; }, function() use ($app) { echo 'Hello World from base route. '; $url = $app->urlFor('hello', array('name' => 'Jimmy')); $link = sprintf('<a href="%s">%s</a>', $url, $url); echo 'Oh, link to hello page for Jimmy is ' . $link;});/* ... */$app->run();

32

MIDDLEWARE

<?php


$app = new Slim();

$app->get('/', function() { //this will be executed before main callable echo "Hello, I'm middleware "; }, function() { //this will be executed before main callable echo "And I'm second middleware "; }, function() use ($app) { echo 'Hello World from base route. '; $url = $app->urlFor('hello', array('name' => 'Jimmy')); $link = sprintf('<a href="%s">%s</a>', $url, $url); echo 'Oh, link to hello page for Jimmy is ' . $link;});/* ... */$app->run();

33

MIDDLEWARE

<?php


$app = new Slim();

$app->get('/', function() { //this will be executed before main callable echo "Hello, I'm middleware "; }, function() { //this will be executed before main callable echo "And I'm second middleware "; }, function() use ($app) { echo 'Hello World from base route. '; $url = $app->urlFor('hello', array('name' => 'Jimmy')); $link = sprintf('<a href="%s">%s</a>', $url, $url); echo 'Oh, link to hello page for Jimmy is ' . $link;});/* ... */$app->run();

And�� so�� on�� -�� everything�� before�� last�� callable�� is�� middleware

34

VIEW

<?php//file index.php


$app = new Slim();

$app->get('/', function() use ($app) { $url = $app->urlFor('hello', array('name' => 'Jimmy')); //default path is "__DIR__ . /templates" return $app->render('view.php', compact('url')); });/* ... */$app->run();

Hello World from base route. Oh, link to hello page for Jimmy is <a href="<?php echo $url?>"><?php echo $url?></a>

35

HTTP CACHE - ETAG

<?php


$app = new Slim();

/* ... */

$app->get('/hello_to(/:name)', function($name = null) use ($app) { if ($name === null) { $name = 'John Doe'; } //auto ETag based on some id - next request with the same name will return 304 Not Modified $app->etag($name); echo 'Hello World to ' . $name;})->name('hello') ->conditions(array('name' => '[A-Za-z]+'));

/* ... */

$app->run();

36

HTTP CACHE - TIME BASED

<?php


$app = new Slim();

/* ... */

$app->get('/hello_to(/:name)', function($name = null) use ($app) { if ($name === null) { $name = 'John Doe'; } $app->lastModified(1327305485); //cache based on time echo 'Hello World to ' . $name;})->name('hello') ->conditions(array('name' => '[A-Za-z]+'));

/* ... */

$app->run();

37

FLASH MESSAGE

<?php


$app = new Slim();

$app->get('/', function() use ($app) { $url = $app->urlFor('hello', array('name' => 'Jimmy')); return $app->render('view.php', compact('url'));});

//redirect to default page with flash message which will be displayed once$app->get('/redirect', function() use ($app) { $app->flash('info', "You were redirected"); $app->redirect($app->request()->getRootUri());});

$app->run();

<?php echo $flash['info'] ?>Hello World from base route. Oh, link to hello page for Jimmy is <a href="<?php echo $url?>"><?php echo $url?></a>

38

CUSTOM 404<?php


$app = new Slim();

//define custom 404 page$app->notFound(function() { echo "I'm custom 404";});

$app->get('/hello_to(/:name)', function($name = null) use ($app) { if ($name === null) { $name = 'John Doe'; } $possibleNames = array('Leonard', 'Sheldon', 'John Doe'); //when name not found, force 404 page if (array_search($name, $possibleNames) === false) { $app->notFound(); } echo 'Hello World to ' . $name;})->name('hello') ->conditions(array('name' => '[A-Za-z]+'));

$app->run();

39

CUSTOM 404<?php


$app = new Slim();

//define custom 404 page$app->notFound(function() { echo "I'm custom 404";});

$app->get('/hello_to(/:name)', function($name = null) use ($app) { if ($name === null) { $name = 'John Doe'; } $possibleNames = array('Leonard', 'Sheldon', 'John Doe'); //when name not found, force 404 page if (array_search($name, $possibleNames) === false) { $app->notFound(); } echo 'Hello World to ' . $name;})->name('hello') ->conditions(array('name' => '[A-Za-z]+'));

$app->run();

Custom�� error�� page�� (500)�� also�� possible

40

REST PATHS #1

<?php


$app = new Slim();//method name maps to HTTP method$app->get('/article'), function(/* ... */) {});$app->post('/article'), function(/* ... */) {});$app->get('/article/:id/'), function(/* ... */) {});$app->put('/article/:id/'), function(/* ... */) {});$app->delete('/article/:id/'), function(/* ... */) {});

41

REST PATHS #2

<?php


$app = new Slim();

//same as previous one$app->map('/article'), function() use ($app) { if ($app->request()->isGet()) { /* ... */ } else if ($app->request()->isPost() { /* ... */ }) else { /* ... */ }})->via('GET', 'POST');$app->map('/article/:id/'), function($id) use ($app) { //same as above})->via('GET', 'PUT', 'DELETE');

ALSO: ENCRYPTED SESSIONS AND

COOKIES, APPLICATION MODES, CUSTOM TEMPLATES

AND MORE...

"But�� I�� can't�� use�� PHP�� 5.3.�� What�� then?"

44

45

PHP 5.2

<?php

require 'Slim/Slim.php';$app = new Slim();

function index() { global $app; echo 'Hello World from base route. '; $url = $app->urlFor('hello', array('Jimmy')); $link = sprintf('<a href="%s">%s</a>', $url, $url); echo 'Oh, link to hello page for Jimmy is ' . $link;}

//last param must return true for is_callable call, so that it's valid$app->get('/', 'index');

/* ... */

$app->run();

46

PHP 5.2

<?php

require 'Slim/Slim.php';$app = new Slim();

function index() { global $app; echo 'Hello World from base route. '; $url = $app->urlFor('hello', array('Jimmy')); $link = sprintf('<a href="%s">%s</a>', $url, $url); echo 'Oh, link to hello page for Jimmy is ' . $link;}

//last param must return true for is_callable call, so that it's valid$app->get('/', 'index');

/* ... */

$app->run();

Somebody�� said,�� that:�� "everytime,�� when�� you�� use�� global,�� unicorn�� dies"�� ;)��

So�� ok,�� second�� approach:

48

49

PHP 5.2

<?php

class Controller { public static $app; public static function index() { echo 'Hello World from base route. '; $url = self::$app->urlFor('hello', array('Jimmy')); $link = sprintf('<a href="%s">%s</a>', $url, $url); echo 'Oh, link to hello page for Jimmy is ' . $link; }}


$app = new Slim();Controller::$app = $app;

//last param must return true for is_callable call, so that it's also valid$app->get('/', array('Controller', 'index'));/* ... */$app->run();

But�� IMHO�� this�� one�� is�� the�� best�� solution:

50

51

PHP 5.2<?php

class Controller { protected $_app; public function __construct(Slim $app) { $this->_app = $app; } public function index() { echo 'Hello World from base route. '; $url = $this->_app->urlFor('hello', array('Jimmy')); $link = sprintf('<a href="%s">%s</a>', $url, $url); echo 'Oh, link to hello page for Jimmy is ' . $link; }}


$app = new Slim();$controller = new Controller($app);

//last param must return true for is_callable call, so that it's also valid$app->get('/', array($controller, 'index'));/* ... */$app->run();

SO, DO YOU REALLY NEED THAT ?
