Member Function Documentation

__call	(		$method,
			$arguments
	)

Magic methods that intercepts all unknown method calls. If a method is called that matches an action on this controller, an url to that action is generated.

Basically, this:

$controller->url_for('foo/bar/baz/' . $param)

is equal to calling this on the Foo_BarController:

$controller->baz($param)

Parameters

String	$method	Called method name
array	$argumetns	Provided arguments

Returns

url to the requested action

Exceptions

Trails_UnknownAction

if no action matches the method

action_link

(

$action

)

Generates the link for an action on this controller without the neccessity to provide the full "path" to the action (since it is implicitely known).

Basically, this:

$controller->link_for('foo/bar/baz/' . $param)

is equal to calling this on the Foo_BarController:

$controller->action_link('baz/' . $param)

Parameters

string

$action

Name of the action

Returns

string to the requested action

action_url

(

$action

)

Generates the url for an action on this controller without the neccessity to provide the full "path" to the action (since it is implicitely known).

Basically, this:

$controller->url_for('foo/bar/baz/' . $param)

is equal to calling this on the Foo_BarController:

$controller->action_url('baz/' . $param)

Parameters

string

$action

Name of the action

Returns

string url to the requested action

after_filter	(		$action,
			$args
	)

Callback function being called after an action is executed.

Parameters

string	Name of the action to perform.
array	An array of arguments to the action.

Returns

void

before_filter	(	&	$action,
		&	$args
	)

Returns

false|void

controller_path ( )

protected

Returns the url path to this controller.

Returns

string url path to this controller

erase_response

(

)

Extended method to inject extended response object.

getBodyElementIdForControllerAndAction (   $unconsumed_path )

protected

Creates the body element id for this controller a given action.

Parameters

string

$unconsumed_path

Unconsumed path to extract action from

Returns

string

has_action

(

$action

)

Returns whether this controller has the specificed action.

Parameters

string

$action

Name of the action

Returns

true if action is defined, false otherwise

link_for

(

$to = ''

)

Returns an escaped URL to a specified route to your Trails application. without first parameter the current action is used if route begins with a / then the current controller ist prepended if second parameter is an array it is passed to URLHeper

Parameters

string	a string containing a controller and optionally an action
strings	optional arguments

Returns

string a URL to this route

perform

(

$unconsumed_path

)

Hooked perform method in order to inject body element id creation.

In order to avoid clashes, these body element id will be joined with a minus sign. Otherwise the controller "x" with action "y_z" would be given the same id as the controller "x/y" with the action "z", namely "x_y_z". With the minus sign this will result in the ids "x-y_z" and "x_y-z".

Plugins will always have a leading 'plugin-' and the decamelized plugin name in front of the id.

Parameters

String

$unconsumed_path

Path segment containing action and optionally arguments or format

Returns

Trails_Response from parent controller

perform_relayed

(

$unconsumed

)

perform a given action/parameter string from an relayed request before_filter and after_filter methods are not called

See Also

perform

Parameters

string

$unconsumed

Returns

Trails_Response

redirect

(

$to

)

Redirects the user another page. Accepts multiple parameters just like url_for().

Parameters

string

$to

See Also

StudipController::url_for()

relay

(

$to_uri

)

relays current request to another controller and returns the response the other controller is given all assigned properties, additional parameters are passed through

Parameters

string

$to_uri

a trails route

Returns

Trails_Response

relayWithRedirect

(

$args

)

Relays current request and performs redirect if neccessary.

Parameters

string

$to_uri

a trails route

Returns

Trails_Response

See Also

StudipController::relay()

relocate

(

$to

)

Relocate the user to another location. This is a specialized version of redirect that differs in two points:

• relocate() will force the browser to leave the current dialog while redirect would refresh the dialog's contents
• relocate() accepts all the parameters that url_for() accepts so it's no longer neccessary to chain url_for() and redirect()

Parameters

String

$to

Location to redirect to

render_csv	(		$data,
			$filename = null,
			$delimiter = ';',
			$enclosure = '"'
	)

Render given data as csv, data is assumed to be utf-8. The first row of data may contain column titles.

Parameters

array	$data	data as two dimensional array
string	$filename	download file name (optional)
string	$delimiter	field delimiter char (optional)
string	$enclosure	field enclosure char (optional)

render_file	(		$file,
			$filename = null,
			$content_type = null,
			$content_disposition = 'attachment',
		Closure	$callback = null,
			$chunk_size = 262144
	)

Renders a file

Parameters

string	$file	Path of the file to render
string	$filename	Name of the file displayed to user (will equal $file when missing)
string	$content_type	Optional content type (will be determined if missing)
string	$content_disposition	Either attachment (default) or inline
Closure	$callback	Optional callback when download has finished
int	$chunk_size	Optional size of chunks to send (default: 256k)

render_json

(

$data

)

render given data as json, data is converted to utf-8

Parameters

mixed

$data

render_pdf ( TCPDF  $pdf,   $filename,   $inline = false  )

protected

Renders a pdf file given by a TCPDF/ExportPDF object.

Parameters

TCPDF	$pdf	TCPDF object to render
string	$filename	Filename
bool	$inline	Should the pdf be displayed inline (default: no)

render_template_as_string	(		$template,
			$layout = null
	)

Renders a given template and returns the resulting string.

Parameters

string	$template	Name of the template file
mixed	$layout	Optional layout

Returns

string

render_temporary_file	(		$file,
			$filename = null,
			$content_type = null,
			$content_disposition = 'attachment',
		Closure	$callback = null,
			$chunk_size = 262144
	)

Renders a temporary file which will be deleted after transmission. This is just a convenience method so you don't have to write the delete callback.

Parameters

string	$file	Path of the file to render
string	$filename	Name of the file displayed to user (will equal $file when missing)
string	$content_type	Optional content type (will be determined if missing)
string	$content_disposition	Either attachment (default) or inline
Closure	$callback	Optional callback when download has finished
int	$chunk_size	Optional size of chunks to send (default: 256k)

rescue

(

$exception

)

Exception handler called when the performance of an action raises an exception.

Parameters

object

the thrown exception

url_for

(

$to = ''

)

Returns a URL to a specified route to your Trails application. without first parameter the current action is used if route begins with a / then the current controller ist prepended if second parameter is an array it is passed to URLHeper

Parameters

string	a string containing a controller and optionally an action
string[]	optional arguments

Returns

string a URL to this route

validate_args	(	&	$args,
			$types = null
	)

Validate arguments based on a list of given types. The types are: 'int', 'float', 'option' and 'string'. If the list of types is NULL or shorter than the argument list, 'option' is assumed for all remaining arguments. 'option' differs from Request::option() in that it also accepts the charaters '-' and ',' in addition to all word characters.

Since Stud.IP 4.0 it is also possible to directly inject SimpleORMap objects. If types is NULL, the signature of the called action is analyzed and any type hint that matches a sorm class will be used to create an object using the argument as the id that is passed to the object's constructor.

If $_autobind is set to true, the created object is also assigned to the controller so that it is available in a view.

Parameters

array	$args	an array of arguments to the action
array	$types	list of argument types (optional)

validate_datetime	(		$datetime,
			$format = 'H:i'
	)

Validate the datetime according to specific format.

Parameters

string	$datetime	the datetime which should be validate
string	$format	the format that the datetime should have by default H:i for time

Returns

bool result of validation
