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.

PREREQUISITES +---------------- +This Phorum module only works on PHP5 and with HTML Purifier 4.0.0 +or later. + +1. UNZIP +-------- +Unzip phorum-htmlpurifier-x.y.z, producing an htmlpurifier folder. +You've already done this step if you're reading this! + +2.

Under normal circumstances, +this would cause a huge security risk, but because we are running +HTML through HTML Purifier, output is guaranteed to be XSS free and +standards-compliant. + +This mod requires HTML input, and previous markup languages need to be +converted accordingly. Thus, it is vital that you create a 'migrate.php' +file that works with your installation. If you're using the built-in +BBCode formatting, simply move migrate.bbcode.php to that place; for +other markup languages, consult said file for instructions on how +to adapt it to your needs. + + -- NOTE ------------------------------------------------- + You can also run this module in parallel with another + formatting module; this module attempts to place itself + at the end of the filtering chain. However, if any + previous modules produce insecure HTML (for instance, + a JavaScript email obfuscator) they will get cleaned. + +This module will not work if 'migrate.php' is not created, and an improperly +made migration file may *CORRUPT* Phorum, so please take your time to +do this correctly. It should go without saying to *BACKUP YOUR DATABASE* +before attempting anything here. If no migration is necessary, you can +simply create a blank migrate.php file.
