Routing and controllers

Request

The request class provides an object oriented interface to global variables such as $_GET, $_POST, $_FILES, $_COOKIE and $_SERVER as well as easy access to request data and other useful request information.

An instance of the request class is always available in all controller classes. It is also easily made available in route closures.

Accessing data

The get method allows you to access query string data.

// Get all query string data (returns an empty array if there is no data)

$all = $this->request->get();

// Get data from a specific key (will return NULL if the key doesn't exist)

$foo = $this->request->get('foo');

// Get data from a specific key and return FASLE if the key doesn't exist

$foo = $this->request->get('foo', false);

The post method allows you to access POST data.

// Get all POST data (returns an empty array if there is no data)

$all = $this->request->post();

// Get data from a specific key (will return NULL if the key doesn't exist)

$foo = $this->request->post('foo');

// Get data from a specific key and return FASLE if the key doesn't exist

$foo = $this->request->post('foo', false);

The put method allows you to access PUT data.

The method expects the request body to be one of the following types; application/x-www-form-urlencoded, text/json or application/json. If you want to access the raw request body then you'll have to use the body method instead.

// Get all PUT data (returns an empty array if there is no data)

$all = $this->request->put();

// Get data from a specific key (will return NULL if the key doesn't exist)

$foo = $this->request->put('foo');

// Get data from a specific key and return FASLE if the key doesn't exist

$foo = $this->request->put('foo', false);

The patch method allows you to access PATCH data.

The method expects the request body to be one of the following types; application/x-www-form-urlencoded, text/json or application/json. If you want to access the raw request body then you'll have to use the body method instead.

// Get all PATCH data (returns an empty array if there is no data)

$all = $this->request->patch();

// Get data from a specific key (will return NULL if the key doesn't exist)

$foo = $this->request->patch('foo');

// Get data from a specific key and return FASLE if the key doesn't exist

$foo = $this->request->patch('foo', false);

The delete method allows you to access DELETE data.

The method expects the request body to be one of the following types; application/x-www-form-urlencoded, text/json or application/json. If you want to access the raw request body then you'll have to use the body method instead.

// Get all DELETE data (returns an empty array if there is no data)

$all = $this->request->delete();

// Get data from a specific key (will return NULL if the key doesn't exist)

$foo = $this->request->delete('foo');

// Get data from a specific key and return FASLE if the key doesn't exist

$foo = $this->request->delete('foo', false);

The body method allows you to access the raw request body.

$body = $this->request->body();

The bodyAsStream method returns the raw request body as a stream. This can be useful if you want to minimize the memory footprint of your application while handling large file uploads via PUT requests.

$body = $this->request->bodyAsStream();

$storageStream = fopen($this->app->getPath() . '/storage/uploads/' . $fileName, 'w');

$filesize = stream_copy_to_stream($body, $storageStream);

The data method allows you to access data from the current request method.

// Get all request data (returns an empty array if there is no data)

$all = $this->request->data();

// Get data from a specific key (will return NULL if the key doesn't exist)

$foo = $this->request->data('foo');

// Get data from a specific key and return FASLE if the key doesn't exist

$foo = $this->request->data('foo', false);

The has method lets you check if a data key exist.

$exists = $this->request->has('foo');

The whitelisted methods returns all request data where keys not in the whitelist have been removed.

// Returns input data where everything except 'foo' and 'bar' keys have been removed

$whitelisted = $this->request->whitelisted(['foo', 'bar']);

// You can also specify default values that will be used if the keys don't exist

$whitelisted = $this->request->whitelisted(['foo', 'bar'], ['foo' => 'baz', 'bar' => 'bax']);

The blacklisted methods returns all request data where keys in the blacklist have been removed.

// Returns input data where the 'foo' and 'bar' keys have been removed

$blacklisted = $this->request->blacklisted(['foo', 'bar']);

// You can also specify default values that will be used if the keys don't exist

$blacklisted = $this->request->blacklisted(['foo', 'bar'], ['baz' => 'foo', 'bax' => 'bar']);

The file method allows you to access files that have been upload via a POST request.

// Get all uploaded files (returns an empty array if there is no data)

$files = $this->request->file();

// Get a specific file or an array of files if it's a multi-upload.

$file = $this->request->file('myfile');

// If you want to get a specific file from a multi-upload then you'll have to add the array key as well

$files = $this->request->file('myfile.0');

Uploaded files are represented as a UploadedFile object. The class extends the SplFileInfo class with the following methods.

Method name Description
getName Returns the name of the file that was uploaded.
getReportedSize Returns the size reported by the client.
getReportedType Returns the mime type reported by the client.
hasError Returns TRUE if there is an error with the uploaded file and FALSE if not.
getErrorCode Returns the error code associated with the error.
getErrorMessage Returns a human friendly error message.
isUploaded Returns TRUE if the file is an actual upload and FALSE if not.
moveTo Moves the file to the specified storage location.

The values reported by the client should not be trusted. Use the getSize method to retrieve the actual filesize.

The server method lets you access server data.

// Get all server data (returns an empty array if there is no data)

$all = $this->request->server();

// Get data from a specific key (will return NULL if the key doesn't exist)

$foo = $this->request->server('SERVER_PORT');

// Get data from a specific key and return '80' if the key doesn't exist

$foo = $this->request->server('SERVER_PORT', 80);

Reading cookies

The cookie method will return the value of the selected cookie.

// Returns the value of the chosen cookie (returns NULL if the cookie doesn't exist)

$value = $this->request->cookie('chocolate');

// Return the value of the chosen cookie and return FASLE if the cookie doesn't exist

$value = $this->request->cookie('chocolate', false);

The signedCookie method will return the value of the selected signed cookie.

// Returns the value of the chosen cookie (returns NULL if the cookie doesn't exist)

$value = $this->request->signedCookie('chocolate');

// Return the value of the chosen cookie and return FASLE if the cookie doesn't exist

$value = $this->request->signedCookie('chocolate', false);

The benefit of using signed cookies over regular cookies is that their values can not be tampered with on the client site.

Setting regular and signed cookies is done using the response class.

Request information

The header method returns the value of the chosen request header.

// Returns the value of the chosen header (returns NULL if the header doesn't exist)

$value = $this->request->header('content-type');

// Returns the value of the chosen header and returns 'text/plain' if the header doesn't exist

$value = $this->request->header('content-type', 'text/plain');

The referer method returns the address that referred the client to the current resource. NULL is returned if there is no referrer.

// Returns the referrer if there is one and NULL if not

$referer = $this->request->referer();

// Returns the referrer if there is one and the URL to the 'home' route if there isn't one

$referer = $this->request->referer($this->urlBuilder->toRoute('home'));

The acceptableContentTypes returns an array of acceptable content types in descending order of preference.

$acceptableContentTypes = $this->request->acceptableContentTypes();

The acceptableLanguages returns an array of acceptable languages in descending order of preference.

$acceptableLanguages = $this->request->acceptableLanguages();

The acceptableCharsets returns an array of acceptable character sets in descending order of preference.

$acceptableCharsets = $this->request->acceptableCharsets();

The acceptableEncodings returns an array of acceptable encodings sets in descending order of preference.

$acceptableEncodings = $this->request->acceptableEncodings();

The ip method returns IP of the client that made the request.

$ip = $this->request->ip();

The isAjax method returns TRUE if the request was made using AJAX and FALSE if not.

$isAjax = $this->request->isAjax();

The isSecure method returns TRUE if the request was made using HTTPS and FALSE if not.

$isSecure = $this->request->isSecure();

The isSafe method returns TRUE if the request method used is considered safe and FALSE if not. The methods that are considered safe are GET and HEAD.

$isSafe = $this->request->isSafe();

The baseURL method returns the base URL of the request.

// A request to 'http://example.org/foo/bar' will return 'http://example.org'

$baseURL = $this->request->baseURL();

The path method will return the request path.

// A request to 'http://example.org/foo/bar' will return '/foo/bar'

$path = $this->request->path();

The language method returns the request language (see the app/config/application.php config file for more information).

$language = $this->request->language();

The languagePrefix method returns the language prefix (see the app/config/application.php config file for more information).

$languagePrefix = $this->request->languagePrefix();

The method method returns the request method used to access the resource.

$method = $this->request->method();

$method = $this->request->realMethod();

The isFaked method returns TRUE if the request method method has been faked and FALSE if not.

$isFaked = $this->request->isFaked();

The username method returns a basic HTTP authentication username of NULL if it isn't set.

$username = $this->request->username();
