Class CakeRequest
A class that helps wrap Request information and particulars about a single request. Provides methods commonly used to introspect on the request headers and request body.
Has both an Array and Object interface. You can access framework parameters using indexes:
$request['controller']
or $request->controller
.

Returns
mixedThrows
CakeException
when an invalid method is called.

Detects if a specific accept header is present.
Parameters
- array
$detect
- Detector options array.
Returns
booleanWhether or not the request is the type you are checking.
_base()source protected
_base( )
Returns a base URL and sets the proper webroot
If CakePHP is called with index.php in the URL even though URL Rewriting is activated (and thus not needed) it swallows the unnecessary part from $base to prevent issue #3318.

Detects if a specific environment variable is present.
Parameters
- array
$detect

Detects if a URL extension is present.
Parameters
- array
$detect
- Detector options array.
Returns
booleanWhether or not the request is the type you are checking.
_headerDetector()source protected
_headerDetector( array $detect )
Detects if a specific header is present.
Parameters
- array
$detect
- Detector options array.
Returns
booleanWhether or not the request is the type you are checking.
_paramDetector()source protected
_paramDetector( array $detect )
Detects if a specific request parameter is present.
Parameters
- array
$detect
- Detector options array.

booleanWhether or not the request is the type you are checking.
_parseAcceptWithQualifier()source protected static
_parseAcceptWithQualifier( string $header )
Parse Accept* headers with qualifier options.

Returns
array_processFileData()source protected
_processFileData( string $path , array $data , string $field )
Recursively walks the FILES array restructuring the data into something sane and useable.

Will merge POST vars prefixed with data
, and ones without into a single array. Variables prefixed with data

optional null - The language to test.
Returns
mixedIf a $language is provided, a boolean. Otherwise the array of accepted languages.
accepts()source public
accepts( string $type null )

$this->request->accepts('application/json');

mixedEither an array of all the types the client accepts or a boolean if they accept the provided type.
addDetector()source public
addDetector( string $name , array $options )
Add a new detector to the list of detectors that a request can use. There are several different formats and types of detectors that can be set.
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.
e.g addDetector('post', array('env' => 'REQUEST_METHOD', 'value' => 'POST'))
Pattern value comparison
Pattern value comparison allows you to compare a value fetched from env()
to a regular expression.
e.g addDetector('iphone', array('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.
e.g addDetector('mobile', array('env' => 'HTTP_USER_AGENT', 'options' => array('Fennec')));
Callback detectors
Callback detectors allow you to provide a 'callback' type to handle the check. The callback will receive the request object as its only parameter.
e.g addDetector('custom', array('callback' => array('SomeClass', 'somemethod')));
Request parameter detectors
Allows for custom detectors on the request parameters.
e.g addDetector('requested', array('param' => 'requested', 'value' => 1)
You can also make parameter detectors that accept multiple values using the options
key. This is useful when you want to check if a request parameter is in a list of options.
addDetector('extension', array('param' => 'ext', 'options' => array('pdf', 'csv'))
Parameters
- string
$name
- The name of the detector.
- array
$options
- The options for the detector definition. See above.
addParams()source public
addParams( array $params )

Returns
CakeRequest

addPaths( array $paths )
Add paths to the requests' paths vars. This will overwrite any existing paths. Provides an easy way to modify, here, webroot and base.
Parameters
- array
$paths
- Array of paths to merge in
Returns
CakeRequest
allowMethod()source public
allowMethod( string|array $methods )

data( string $name )
Provides a read/write accessor for $this->data
. Allows you to use a syntax similar to CakeSession
for reading post data.

When reading values you will get null
for keys/values that do not exist.
Writing values
$request->data('Post.title', 'New post!');
You can write to any value, even paths/keys that do not exist, and the arrays will be created for you.
