HTTP Request System Migration

TorrentPier has replaced direct superglobal access ($_GET, $_POST, $_REQUEST, $_COOKIE, $_SERVER, $_FILES) with a modern HTTP Request abstraction built on symfony/http-foundation.

Quick Migration Overview​

// Old way (deprecated)
$topic_id = (int)$_GET['t'];
$mode = $_REQUEST['mode'] ?? '';
$submit = !empty($_POST['submit']);
$session = $_COOKIE['bb_data'];
$uri = $_SERVER['REQUEST_URI'];
$file = $_FILES['attachment'];

// New way (recommended)
$topic_id = request()->getInt('t');
$mode = request()->getString('mode');
$submit = request()->post->has('submit');
$session = request()->cookies->get('bb_data');
$uri = request()->getRequestUri();
$file = request()->files->get('attachment');

API Reference​

Properties (Symfony InputBag)​

Access specific parameter sources directly via properties:

request()->query->get('key')      // GET parameters ($_GET equivalent)
request()->post->get('key')       // POST parameters ($_POST equivalent)
request()->cookies->get('key')    // Cookies ($_COOKIE equivalent)
request()->server->get('key')     // Server variables ($_SERVER equivalent)
request()->headers->get('key')    // HTTP headers
request()->files->get('key')      // Uploaded files ($_FILES equivalent)

Each property returns a Symfony bag with methods like get(), has(), all(), getInt(), getBoolean(), etc.

Typed Getters (POST > GET Priority)​

Convenience methods that check POST first, then GET:

request()->get('key')             // mixed - raw value from POST or GET
request()->has('key')             // bool - check if parameter exists
request()->all()                  // array - all merged parameters
request()->getInt('key')          // int - integer value (default: 0)
request()->getString('key')       // string - string value (default: '')
request()->getBool('key')         // bool - boolean value (default: false)
request()->getFloat('key')        // float - float value (default: 0.0)
request()->getArray('key')        // array - array value (default: [])

Request Metadata​

request()->getMethod()            // HTTP method (GET, POST, etc.)
request()->isPost()               // Check if POST request
request()->isGet()                // Check if GET request
request()->isAjax()               // Check if AJAX request
request()->isSecure()             // Check if HTTPS
request()->getClientIp()          // Client IP address
request()->getRequestUri()        // Request URI with query string
request()->getPathInfo()          // Request path without query string
request()->getQueryString()       // Query string only
request()->getHost()              // Host name
request()->getScheme()            // Scheme (http or https)
request()->getUserAgent()         // User-Agent header
request()->getReferer()           // Referer header
request()->getContentType()       // Content-Type header
request()->getContent()           // Raw request body
request()->getSymfonyRequest()    // Underlying Symfony Request object

Migration Examples​

GET Parameters​

// Before
$forum_id = isset($_GET['f']) ? (int)$_GET['f'] : 0;
$start = abs((int)($_GET['start'] ?? 0));

// After
$forum_id = request()->query->getInt('f');
$start = abs(request()->query->getInt('start'));

POST Parameters​

// Before
$submit = !empty($_POST['submit']);
$message = $_POST['message'] ?? '';

// After
$submit = request()->post->has('submit');
$message = request()->post->get('message', '');

REQUEST (POST > GET)​

// Before
$mode = (string)@$_REQUEST['mode'];
$topic_id = (int)$_REQUEST['t'];

// After
$mode = request()->getString('mode');
$topic_id = request()->getInt('t');

Cookies​

// Before
$tracks = !empty($_COOKIE[$name]) ? json_decode($_COOKIE[$name], true) : [];

// After
$cookie = request()->cookies->get($name);
$tracks = $cookie ? json_decode($cookie, true) : [];

Server Variables​

// Before
$request_uri = $_SERVER['REQUEST_URI'] ?? '/';
$remote_addr = $_SERVER['REMOTE_ADDR'];

// After
$request_uri = request()->getRequestUri();
$remote_addr = request()->getClientIp();

File Uploads​

// Before
if (!empty($_FILES['attachment']['name'])) {
    $file = $_FILES['attachment'];
}

// After
$file = request()->files->get('attachment');
if ($file && $file->isValid()) {
    // Process uploaded file
}

Symfony Request Access​

For advanced operations, access the underlying Symfony Request object:

$symfonyRequest = request()->getSymfonyRequest();
