Member Function Documentation

error()

HTMLPurifier_VarParser::error ( $msg )

protectedinherited

Throws an exception.

Exceptions

HTMLPurifier_VarParserException

errorGeneric()

HTMLPurifier_VarParser::errorGeneric ( $var, $type )

protectedinherited

Generic error for if a type didn't work.

Parameters

mixed	$var
int	$type

errorInconsistent()

HTMLPurifier_VarParser::errorInconsistent ( $class, $type )

protectedinherited

Throws an inconsistency exception.

Note

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

Parameters

string	$class
int	$type

Exceptions

HTMLPurifier_Exception

evalExpression()

HTMLPurifier_VarParser_Native::evalExpression ( $expr )

protected

Parameters

string

$expr

Return values

mixed

Exceptions

HTMLPurifier_VarParserException

getTypeName()

static HTMLPurifier_VarParser::getTypeName ( $type )

staticinherited

Parameters

int

$type

Return values

string

parse()

HTMLPurifier_VarParser::parse ( $var, $type, $allow_null = false )

finalinherited

Validate a variable according to type.

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

Parameters

mixed	$var	Variable to validate
int	$type	Type of variable, see HTMLPurifier_VarParser->types
bool	$allow_null	Whether or not to permit null as a value

Return values

string

Validated and type-coerced variable

Exceptions

HTMLPurifier_VarParserException

parseImplementation()

HTMLPurifier_VarParser_Native::parseImplementation ( $var, $type, $allow_null )

protected

Parameters

mixed	$var
int	$type
bool	$allow_null

Return values

null|string

Reimplemented from HTMLPurifier_VarParser.

Member Data Documentation

$stringTypes

HTMLPurifier_VarParser::$stringTypes

staticinherited

Initial value:

= array(
        self::C_STRING => true,
        self::ISTRING => true,
        self::TEXT => true,
        self::ITEXT => true,
    )

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

$types

HTMLPurifier_VarParser::$types

staticinherited

Initial value:

= 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
    )

Lookup table of allowed types.

Mainly for backwards compatibility, but also convenient for transforming string type names to the integer constants.
