-MODx Plugin
-
-MODx <http://www.modxcms.com/> is an open source PHP application framework.
-I first came across them in my referrer logs when tillda asked if anyone
-could implement an HTML Purifier plugin. This forum thread
-<http://modxcms.com/forums/index.php/topic,6604.0.html> eventually resulted
-in the fruition of this plugin that davidm says, "is on top of my favorite
-list." HTML Purifier goes great with WYSIWYG editors!
-
-
-
-1. Credits
-
-PaulGregory wrote the overall structure of the code. I added the
-slashes hack.
-
-
-
-2. Install
-
-First, you need to place HTML Purifier library somewhere. The code here
-assumes that you've placed in MODx's assets/plugins/htmlpurifier (no version
-number).
-
-Log into the manager, and navigate:
-
-Resources > Manage Resources > Plugins tab > New Plugin
-
-Type in a name (probably HTML Purifier), and copy paste this code into the
-textarea:
-
---------------------------------------------------------------------------------
-$e = &$modx->Event;
-if ($e->name == 'OnBeforeDocFormSave') {
- global $content;
-
- include_once '../assets/plugins/htmlpurifier/library/HTMLPurifier.auto.php';
- $purifier = new HTMLPurifier();
-
- static $magic_quotes = null;
- if ($magic_quotes === null) {
- // this is an ugly hack because this hook hasn't
- // had the backslashes removed yet when magic_quotes_gpc is on,
- // but HTMLPurifier must not have the quotes slashed.
- $magic_quotes = get_magic_quotes_gpc();
- }
-
- if ($magic_quotes) $content = stripslashes($content);
- $content = $purifier->purify($content);
- if ($magic_quotes) $content = addslashes($content);
-}
---------------------------------------------------------------------------------
-
-Then navigate to the System Events tab and check "OnBeforeDocFormSave".
-Save the plugin. HTML Purifier now is integrated!
-
-
-
-3. Making sure it works
-
-You can test HTML Purifier by deliberately putting in crappy HTML and seeing
-whether or not it gets fixed. A better way is to put in something like this:
-
-<p lang="fr">Il est bon</p>
-
-...and seeing whether or not the content comes out as:
-
-<p lang="fr" xml:lang="fr">Il est bon</p>
-
-(lang to xml:lang synchronization is one of the many features HTML Purifier
-has).
-
-
-
-4. Caveat Emptor
-
-This code does not intercept save requests from the QuickEdit plugin, this may
-be added in a later version. It also modifies things on save, so there's a
-slight chance that HTML Purifier may make a boo-boo and accidently mess things
-up (the original version is not saved).
-
-Finally, make sure that MODx is using UTF-8. If you are using, say, a French
-localisation, you may be using Latin-1, if that's the case, configure
-HTML Purifier properly like this:
-
-$config = HTMLPurifier_Config::createDefault();
-$config->set('Core', 'Encoding', 'ISO-8859-1'); // or whatever encoding
-$purifier = new HTMLPurifier($config);
-

-5. Known Bugs
-
-'rn' characters sometimes mysteriously appear after purification. We are
-currently investigating this issue. See: <http://htmlpurifier.org/phorum/read.php?3,1866>

-
-6. See Also
-
-A modified version of Jot 1.1.3 is available, which integrates with HTML
-Purifier. You can check it out here: <http://modxcms.com/forums/index.php/topic,25621.msg161970.html>
