addDetector(string $name, Closure|array $detector): void
Add a new detector to the list of detectors that a request can use. There are several different types of detectors that can be set.
Callback comparison
Callback detectors allow you to provide a closure to handle the check. The closure will receive the request object as its only parameter.
addDetector('custom', function ($request) { //Return a boolean });
Environment value comparison
An environment value comparison, compares a value fetched from env()
to a known value
the environment value is equality checked against the provided value.
addDetector('post', ['env' => 'REQUEST_METHOD', 'value' => 'POST']);
Request parameter comparison
Allows for custom detectors on the request parameters.
addDetector('admin', ['param' => 'prefix', 'value' => 'admin']);
Accept comparison
Allows for detector to compare against Accept header value.
addDetector('csv', ['accept' => 'text/csv']);
Header comparison
Allows for one or more headers to be compared.
addDetector('fancy', ['header' => ['X-Fancy' => 1]);
The param
, env
and comparison types allow the following
value comparison options:
Pattern value comparison
Pattern value comparison allows you to compare a value fetched from env()
to a regular expression.
addDetector('iphone', ['env' => 'HTTP_USER_AGENT', 'pattern' => '/iPhone/i']);
Option based comparison
Option based comparisons use a list of options to create a regular expression. Subsequent calls to add an already defined options detector will merge the options.
addDetector('mobile', ['env' => 'HTTP_USER_AGENT', 'options' => ['Fennec']]);
You can also make compare against multiple values
using the options
key. This is useful when you want to check
if a request value is in a list of options.
addDetector('extension', ['param' => '_ext', 'options' => ['pdf', 'csv']]

getAttribute(string $name, mixed $default = null): mixed
Read an attribute from the request, or get the default
Retrieves a single derived request attribute as described in getAttributes(). If the attribute has not been previously set, returns the default value as provided.
This method obviates the need for a hasAttribute() method, as it allows specifying a default value to return if the attribute is not found.
Parameters
-
string
$name The attribute name.
-
mixed
$default optional The default value if the attribute has not been set.
Returns
mixed
getAttributes() ¶ public

Read cookie data from the request's cookie data.
Parameters
-
string
$key The key or dotted path you want to read.
-
array|string|null
$default optional The default value if the cookie is not set.
Returns
array|string|null
getCookieCollection() ¶ public
getCookieCollection(): Cake\Http\Cookie\CookieCollection
Get a cookie collection based on the request's cookies
The CookieCollection lets you interact with request cookies using
\Cake\Http\Cookie\Cookie
objects and can make converting request cookies
into response cookies easier.
This method will create a new cookie collection each time it is called.
This is an optimization that allows fewer objects to be allocated until
the more complex CookieCollection is needed. In general you should prefer
getCookie()
and getCookieParams()
over this method. Using a CookieCollection
is ideal if your cookies contain complex JSON encoded data.
Returns
Cake\Http\Cookie\CookieCollection
getCookieParams() ¶ public
getCookieParams(): array<string, mixed>
Get all the cookie data from the request.
Retrieves cookies sent by the client to the server.
The data MUST be compatible with the structure of the $_COOKIE superglobal.
Returns
array<string, mixed>
getData() ¶ public
getData(string|null $name = null, mixed $default = null): mixed
Provides a safe accessor for request data. Allows you to use Hash::get() compatible paths.
Reading values.
// get all data
$request->getData();
// Read a specific field.
$request->getData('Post.title');
// With a default value.
$request->getData('Post.not there', 'default value');
When reading values you will get null
for keys/values that do not exist.
Developers are encouraged to use getParsedBody() if they need the whole data array, as it is PSR-7 compliant, and this method is not. Using Hash::get() you can also get single params.
PSR-7 Alternative
$value = Hash::get($request->getParsedBody(), 'Post.id');
Parameters
-
string|null
$name optional Dot separated name of the value to read. Or null to read all data.
-
mixed
$default optional The default data.
Returns
mixed

This method MUST be implemented in such a way as to retain the immutability of the message, and MUST return an instance that has the new and/or updated header and value.
Parameters
-
string
$name The header name.
-
string|string[]
$value The header value
Returns
static

withMethod() ¶ public
withMethod(string $method): static
Update the request method and get a new instance.
While HTTP method names are typically all uppercase characters, HTTP method names are case-sensitive and thus implementations SHOULD NOT modify the given string.
This method MUST be implemented in such a way as to retain the immutability of the message, and MUST return an instance that has the changed request method.
Parameters
-
string
$method The HTTP method to use.
Returns
static
Links
withParam() ¶ public
withParam(string $name, mixed $value): static
Update the request with a new routing parameter
Returns an updated request object. This method returns a new request object and does not mutate the request in-place.
Parameters
-
string
$name The dot separated path to insert $value at.
-
mixed
$value The value to insert into the the request parameters.
Returns
static
withParsedBody() ¶ public
withParsedBody(null|array|object $data): static
Update the parsed body and get a new instance.
These MAY be injected during instantiation.
If the request Content-Type is either application/x-www-form-urlencoded or multipart/form-data, and the request method is POST, use this method ONLY to inject the contents of $_POST.
The data IS NOT REQUIRED to come from $_POST, but MUST be the results of deserializing the request body content. Deserialization/parsing returns structured data, and, as such, this method ONLY accepts arrays or objects, or a null value if nothing was available to parse.
As an example, if content negotiation determines that the request data is a JSON payload, this method could be used to create a request instance with the deserialized parameters.
This method MUST be implemented in such a way as to retain the immutability of the message, and MUST return an instance that has the updated body parameters.
Parameters
-
null|array|object
$data The deserialized body data. This will typically be in an array or object.
Returns
static
withProtocolVersion() ¶ public
withProtocolVersion(string $version): static
Return an instance with the specified HTTP protocol version.
The version string MUST contain only the HTTP version number (e.g., "1.1", "1.0").
Parameters
-
string
$version HTTP protocol version
Returns
static
withQueryParams() ¶ public
withQueryParams(array $query): static
Update the query string data and get a new instance.
These values SHOULD remain immutable over the course of the incoming request. They MAY be injected during instantiation, such as from PHP's $_GET superglobal, or MAY be derived from some other value such as the URI. In cases where the arguments are parsed from the URI, the data MUST be compatible with what PHP's parse_str() would return for purposes of how duplicate query parameters are handled, and how nested sets are handled.
Setting query string arguments MUST NOT change the URI stored by the request, nor the values in the server params.
This method MUST be implemented in such a way as to retain the immutability of the message, and MUST return an instance that has the updated query string arguments.
Parameters
-
array
$query The query string data to use
Returns
static
Links
withRequestTarget() ¶ public
withRequestTarget(string $requestTarget): static
Create a new instance with a specific request-target.
You can use this method to overwrite the request target that is inferred from the request's Uri. This also lets you change the request target's form to an absolute-form, authority-form or asterisk-form
Parameters
-
string
$requestTarget The request target.
Returns
static

withUploadedFiles() ¶ public
withUploadedFiles(array $uploadedFiles): static
Update the request replacing the files, and creating a new instance.
This method MUST be implemented in such a way as to retain the immutability of the message, and MUST return an instance that has the updated body parameters.
Parameters
-
array
$uploadedFiles An array of uploaded file objects.
Returns
static
Throws
InvalidArgumentException
when $files contains an invalid object.
withUri() ¶ public
withUri(UriInterface $uri, bool $preserveHost = false): static
Return an instance with the specified uri
Warning Replacing the Uri will not update the base
, webroot

UriInterface
$uri The new request uri
-
bool
$preserveHost optional Whether the host should be retained.
Returns
static
withoutAttribute() ¶ public
withoutAttribute(string $name): static
Return an instance without the specified request attribute.
