Constructor & Destructor Documentation

__construct()

__construct

(

$id = null

)

Constructor of the object. Provides a fallback if a url is passed instead of the usually expected numeric id in order to not break backward compatibility. But this constructor will fail miserably if a url is passed that is not in the database. This was chosen by design to encourage the correct use of an id.

Parameters

mixed

$id

Numeric id, existing url or null

Member Function Documentation

configure()

static configure (   $config = array() )

staticprotected

Configures this model.

Parameters

Array

$config

Configuration array

fetch()

fetch

(

)

Fetches information from the url by getting the contents of the webpage, parse the webpage and extract the information from the opengraph meta-tags. If the site doesn't have any opengraph-metatags it is in fact no opengraph node and thus no data will be stored in the database. Only $url['is_opengraph'] === '0' indicates that the site is no opengraph node at all.

Todo:

The combination of FileManager::fetchURLMetadata() and the following request leads to two requests for the open graph data. This should be fixed due to performance reasons.

Here is the call graph for this function:

Here is the caller graph for this function:

fromURL()

static fromURL (   $url )

static

Create an instance of this model given url. Differs from findOneByURL insofar that it will return a new object with the given url set instead of null.

Parameters

String

$url

URL to find

Returns

OpenGraphURL Either existing instance or a new instance for the given url

Here is the caller graph for this function:

getAudioFiles()

getAudioFiles

(

)

Returns an array with all audiofiles that are provided by the opengraph-node. Each array-entry is an array itself with the url as first parameter and the content-type (important for <audio> tags) as the second.

Returns

array(array($url, $content_type), ...)

Here is the call graph for this function:

getMediaFiles()

getMediaFiles (   $type )

protected

Returns an array with all mediafiles that are provided by the opengraph-node. Each array-entry is an array itself with the url as first parameter and the content-type (important for <audio> or <video> tags) as the second.

Parameters

string

$type

"audio" or "video"

Returns

array(array($url, $content_type), ...)

Here is the call graph for this function:

Here is the caller graph for this function:

getVideoFiles()

getVideoFiles

(

)

Returns an array with all videofiles that are provided by the opengraph-node. Each array-entry is an array itself with the url as first parameter and the content-type (important for <video> tags) as the second.

Returns

array(array($url, $content_type), ...)

Here is the call graph for this function:

render()

render

(

)

Renders a small box with the information of the opengraph url. Used in blubber and in the forum.

Returns

string html output of the box.

Here is the call graph for this function:

store()

store

(

)

Stores the object and fetches the opengraph information when either the object is new or outdated.

Returns

int Number of updated records
