HTMLPurifier_URIFilter_DisableExternalResources
extends HTMLPurifier_URIFilter_DisableExternal
in package
Chainable filters for custom URI processing.
These filters can perform custom actions on a URI filter object, including transformation or blacklisting. A filter named Foo must have a corresponding configuration directive %URI.Foo, unless always_load is specified to be true.
The following contexts may be available while URIFilters are being processed:
- EmbeddedURI: true if URI is an embedded resource that will
be loaded automatically on page load
- CurrentToken: a reference to the token that is currently
being processed
- CurrentAttr: the name of the attribute that is currently being
processed
- CurrentCSSProperty: the name of the CSS property that is
currently being processed (if applicable)
