Detailed Description

This is the navigation base class that maintains the global navigation structure. All navigation objects are stored in a tree and can be accessed by their "path names", just like file names in a normal file system. The "root" of the tree is '/'.

So you can do for example:

$navigation = new Navigation('Home', 'index.php'); $profilenav = new Navigation('Profile', 'profile.php');

$navigation->addSubNavigation('profile', $profilenav);

Navigation::addItem('/home', $navigation); Navigation::activateItem('/home/profile');

Constructor & Destructor Documentation

__construct	(	$title,
		$url = `NULL`,
		$params = `NULL`
	)

Initialize a new Navigation instance with the given title and URL (optional).

Member Function Documentation

static activateItem ( $path )

static

Mark the navigation item at the given path as active. This is just a shortcut for doing:

Navigation::getItem($path)->setActive(true)

Parameters

string $path path of navigation item

activeSubNavigation ( )

Get the active subnavigation item of this navigation (if there is one). Returns NULL if the subnavigation has no active item.

static addItem	(		$path,
		Navigation	$navigation
	)

static

Add a new navigation item at the given path. If there is already an item with this path, the old one is replaced by the new item.

Parameters

string	$path	path of new navigation item
object	$navigation	navigation item to add

addSubNavigation	(		$name,
		Navigation	$navigation
	)

Add the given item to the subnavigation of this object. This also assigns a name to this subnavigation item. If there is already a subitem with this name, the old one is replaced by the new item.

Parameters

string	$name	name of new navigation item
object	$navigation	navigation item to add

getBadgeNumber ( )

Return the badge number of this navigation item.

Returns: int the badge number

getBadgeTimestamp ( )

Return the badge number of this navigation item.

Returns: int the badge number

getDescription ( )

Return the description associated with this navigation item.

Returns: string description of item or NULL (no description set)

getImage ( )

Return the current image associated with this navigation item.

Returns: Icon an instance of class Icon depicting this item or NULL

getImageTag ( )

Shorthand method for creating an appropriate image tag for display.

Returns: string HTML tag snippet for the image

static getItem ( $path )

static

Return the navigation item at the given path.

Parameters

string $path path of navigation item

Exceptions

InvalidArgumentException if the item cannot be found

getIterator ( )

IteratorAggregate: Create interator for request parameters.

getLinkAttributes ( )

Return the attributes that should be used in the link element surrounding this item's icon image.

Returns: array the attributes to pass to the surrounding link element

getSubNavigation ( )

Return the list of subnavigation items of this object.

getTitle ( )

Return the current title associated with this navigation item.

Returns: string title of item or NULL (no title set)

getURL ( )

Return the current URL associated with this navigation item. If not URL is set but there are subnavigation items, the URL of the first visible subnavigation item is returned.

Returns: string url of item or NULL (no URL set)

hasBadgeNumber ( )

Determines whether this navigation item has a badge number.

static hasItem ( $path )

static

Test whether there is a navigation item at the given path.

Parameters

string $path path of navigation item

initItem ( )

used to defer initialization of item metadata, override in subclasses if initialization is costly

initSubNavigation ( )

protected

Initialize the subnavigation of this item. This method is called once before the first item is added or removed.

static insertItem	(		$path,
		Navigation	$navigation,
			$where
	)

static

Add a new navigation item at the given path. The new item is inserted immediately before the item with the name given by $where (at the same level in the tree).

Parameters

string	$path	path of new navigation item
object	$navigation	navigation item to add
string	$where	insert it before this item

insertSubNavigation	(		$name,
		Navigation	$navigation,
			$where
	)

Add the given item to the subnavigation of this object. The new item is inserted immediately before the item with the name given by $where (if there is one, it is appended to the end otherwise). This also assigns a name to this subnavigation item.

Parameters

string	$name	name of new navigation item
object	$navigation	navigation item to add
string	$where	insert it before this item

isActive ( )

Determine whether this navigation item is active.

isEnabled ( )

Return whether this navigation item is enabled.

isVisible ( $needs_image = false )

Return whether this navigation item is visible.

Parameters

boolean $needs_image requires an image

static removeItem ( $path )

static

Remove the navigation item at the given path (if there is an item with this path).

Parameters

string $path path of item to remove

removeSubNavigation ( $name )

Remove the given item from the subnavigation of this object (if there is an item with this name).

Parameters

string $name name of item to remove

setActive ( $active )

Set the active status of this item. This can be used to override heuristics used by the class to determine this automatically.

Parameters

boolean $active new active status

setActiveImage	(	\Icon	$image = `null`,
			$linkAttributes = `[]`
	)

Set the image for the active state of this navigation item. If no active image is set, the normal image is used for the active state. Additional HTML attributes can be passed using the $options parameter (like 'style' or 'onclick').

Parameters

Icon	$image	an instance of class Icon depicting this item
array	$link_attributes	additional link attributes

setBadgeNumber ( $badgeNumber )

Set the badge number of this navigation item.

Parameters

string $badgeNumber the badge number

setBadgeTimestamp ( $badgeTimestamp )

Set the badge number of this navigation item.

Parameters

string $badgeNumber the badge number

setDescription ( $description )

Set the description of this navigation item.

Parameters

string $description description text

setEnabled ( $enabled )

Set the enabled status of this item. Disabled items are still visible but cannot be clicked.

Parameters

boolean $enabled new enabled status

setImage	(	\Icon	$image = `null`,
			$linkAttributes = `[]`
	)

Set the image of this navigation item. Additional HTML attributes can be passed using the $options parameter (like 'style' or 'onclick').

Parameters

Icon	$image	an instance of class Icon depicting this item
array	$link_attributes	additional link attributes

setLinkAttributes ( $attributes )

Set the attributes that should be used in the link element surrounding this item's icon image.

Parameters

array $attributes the attributes to pass to the surrounding link element

static setRootNavigation ( Navigation $navigation )

static

Set the root of the navigation tree. Must be called before any further items can be added to the tree.

Parameters

object $navigation root navigation item

setTitle ( $title )

Set the title of this navigation item.

Parameters

string $title display title

setURL	(	$url,
		$params = `NULL`
	)

Set the URL of this navigation item. Additional URL parameters can be passed using the (optional) second parameter.

Parameters

string	$title	display title
array	$params	additional URL parameters
