Constructor & Destructor Documentation

◆ __construct()

HTMLPurifier_Config::__construct ( $definition,
$parent = null )

Constructor.

Parameters
HTMLPurifier_ConfigSchema$definitionConfigSchema that defines what directives are allowed.
HTMLPurifier_PropertyList$parent

Member Function Documentation

◆ create()

static HTMLPurifier_Config::create ( $config,
$schema = null )
static

Convenience constructor that creates a config object based on a mixed var.

Parameters
mixed$configVariable that defines the state of the config object. Can be: a HTMLPurifier_Config() object, an array of directives based on loadArray(), or a string filename of an ini file.
HTMLPurifier_ConfigSchema$schemaSchema object
Return values
HTMLPurifier_ConfigConfigured object

◆ createDefault()

static HTMLPurifier_Config::createDefault ( )
static

Convenience constructor that creates a default configuration object.

Return values
HTMLPurifier_Configdefault object.

◆ get()

HTMLPurifier_Config::get ( $key,
$a = null )

Retrieves a value from the configuration.

Parameters
string$keyString key
mixed$a
Return values
mixed

◆ getAll()

HTMLPurifier_Config::getAll ( )

Retrieves all directives, organized by namespace.

Warning
This is a pretty inefficient function, avoid if you can

◆ getAllowedDirectivesForForm()

static HTMLPurifier_Config::getAllowedDirectivesForForm ( $allowed,
$schema = null )
static

Returns a list of array(namespace, directive) for all directives that are allowed in a web-form context as per an allowed namespaces/directives list.

Parameters
array$allowedList of allowed namespaces/directives
HTMLPurifier_ConfigSchema$schemaSchema to use, if not global copy
Return values
array

◆ getBatch()

HTMLPurifier_Config::getBatch ( $namespace)

Retrieves an array of directives to values from a given namespace.

Parameters
string$namespaceString namespace
Return values
array

◆ getBatchSerial()

HTMLPurifier_Config::getBatchSerial ( $namespace)

Returns a SHA-1 signature of a segment of the configuration object that uniquely identifies that particular configuration.

Parameters
string$namespaceNamespace to get serial for
Return values
string
Note
Revision is handled specially and is removed from the batch before processing!

◆ getCSSDefinition()

HTMLPurifier_Config::getCSSDefinition ( $raw = false,
$optimized = false )

Retrieves object reference to the CSS definition.

Parameters
bool$rawReturn a copy that has not been setup yet. Must be called before it's been setup, otherwise won't work.
bool$optimizedIf true, this method may return null, to indicate that a cached version of the modified definition object is available and no further edits are necessary. Consider using maybeGetRawCSSDefinition, which is more explicitly named, instead.
Return values
HTMLPurifier_CSSDefinition|null

◆ getDefinition()

HTMLPurifier_Config::getDefinition ( $type,
$raw = false,
$optimized = false )

Retrieves a definition.

Parameters
string$typeType of definition: HTML, CSS, etc
bool$rawWhether or not definition should be returned raw
bool$optimizedOnly has an effect when $raw is true. Whether or not to return null if the result is already present in the cache. This is off by default for backwards compatibility reasons, but you need to do things this way in order to ensure that caching is done properly. Check out enduser-customize.html for more details. We probably won't ever change this default, as much as the maybe semantics is the "right thing to do."
Exceptions
HTMLPurifier_Exception
Return values
HTMLPurifier_Definition|null

◆ getHTMLDefinition()

HTMLPurifier_Config::getHTMLDefinition ( $raw = false,
$optimized = false )

Retrieves object reference to the HTML definition.

Parameters
bool$rawReturn a copy that has not been setup yet. Must be called before it's been setup, otherwise won't work.
bool$optimizedIf true, this method may return null, to indicate that a cached version of the modified definition object is available and no further edits are necessary. Consider using maybeGetRawHTMLDefinition, which is more explicitly named, instead.
Return values
HTMLPurifier_HTMLDefinition|null

◆ getSerial()

HTMLPurifier_Config::getSerial ( )

Returns a SHA-1 signature for the entire configuration object that uniquely identifies that particular configuration.

Return values
string

◆ getURIDefinition()

HTMLPurifier_Config::getURIDefinition ( $raw = false,
$optimized = false )

Retrieves object reference to the URI definition.

Parameters
bool$rawReturn a copy that has not been setup yet. Must be called before it's been setup, otherwise won't work.
