HTMLPurifier_VarParser_Native extends HTMLPurifier_VarParser
in package

This variable parser uses PHP's internal code engine. Because it does this, it can represent all inputs; however, it is dangerous and cannot be used by users.

Properties

$stringTypes  : mixed
Lookup table of types that are string, and can have aliases or allowed value lists.
$types  : mixed
Lookup table of allowed types. Mainly for backwards compatibility, but also convenient for transforming string type names to the integer constants.

Methods

getTypeName()  : string
parse()  : string
Validate a variable according to type.
error()  : mixed
Throws an exception.
errorGeneric()  : mixed
Generic error for if a type didn't work.
errorInconsistent()  : mixed
Throws an inconsistency exception.
evalExpression()  : mixed
parseImplementation()  : null|string
Actually implements the parsing. Base implementation does not do anything to $var. Subclasses should overload this!

Properties

$stringTypes

Lookup table of types that are string, and can have aliases or allowed value lists.

public static mixed $stringTypes = array(self::C_STRING => \true, self::ISTRING => \true, self::TEXT => \true, self::ITEXT => \true)

$types

Lookup table of allowed types. Mainly for backwards compatibility, but also convenient for transforming string type names to the integer constants.

public static mixed $types = array('string' => self::C_STRING, 'istring' => self::ISTRING, 'text' => self::TEXT, 'itext' => self::ITEXT, 'int' => self::C_INT, 'float' => self::C_FLOAT, 'bool' => self::C_BOOL, 'lookup' => self::LOOKUP, 'list' => self::ALIST, 'hash' => self::HASH, 'mixed' => self::C_MIXED)

Methods

getTypeName()

public static getTypeName(int $type) : string
Parameters
$type : int
Return values
string

parse()

Validate a variable according to type.

public final parse(mixed $var, int $type[, bool $allow_null = false ]) : string

It may return NULL as a valid type if $allow_null is true.

Parameters
$var : mixed

Variable to validate

$type : int

Type of variable, see HTMLPurifier_VarParser->types

$allow_null : bool = false

Whether or not to permit null as a value

Tags
throws
HTMLPurifier_VarParserException
Return values
string —

Validated and type-coerced variable

errorGeneric()

Generic error for if a type didn't work.

protected errorGeneric(mixed $var, int $type) : mixed
Parameters
$var : mixed
$type : int

errorInconsistent()

Throws an inconsistency exception.

protected errorInconsistent(string $class, int $type) : mixed
Parameters
$class : string
$type : int
Tags
note

This should not ever be called. It would be called if we extend the allowed values of HTMLPurifier_VarParser without updating subclasses.

throws
HTMLPurifier_Exception

parseImplementation()

Actually implements the parsing. Base implementation does not do anything to $var. Subclasses should overload this!

protected parseImplementation(mixed $var, int $type, bool $allow_null) : null|string
Parameters
$var : mixed
$type : int
$allow_null : bool
Return values
null|string
