5. Using the code
|
||||
For example, you can fine tune allowed elements and attributes, convert
|
||||
relative URLs to absolute ones, and even autoparagraph input text! These
|
||||
are, respectively, %HTML.Allowed, %URI.MakeAbsolute and %URI.Base, and
|
||||
%AutoFormat.AutoParagraph. The %Namespace.Directive naming convention
|
||||
translates to:
|
||||
|
||||
The interface is mind-numbingly simple:
|
||||
$config->set('Namespace', 'Directive', $value);
|
||||
|
||||
$purifier = new HTMLPurifier();
|
||||
$clean_html = $purifier->purify( $dirty_html );
|
||||
E.g.
|
||||
|
||||
...or, if you're using the configuration object:
|
||||
|
||||
$purifier = new HTMLPurifier($config);
|
||||
$clean_html = $purifier->purify( $dirty_html );
|
||||
|
||||
That's it! For more examples, check out docs/examples/ (they aren't very
|
||||
different though). Also, docs/enduser-slow.html gives advice on what to
|
||||
do if HTML Purifier is slowing down your application.
|
||||
$config->set('HTML', 'Allowed', 'p,b,a[href],i');
|
||||
$config->set('URI', 'Base', 'http://www.example.com');
|
||||
$config->set('URI', 'MakeAbsolute', true);
