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. MOVE +------- +Move the htmlpurifier folder to the mods/ folder of your Phorum +installation, so the directory structure looks like: + +phorum/ + mods/ + htmlpurifier/ + INSTALL - this install file + info.txt, ... - the module files + htmlpurifier/ + +3. INSTALL HTML PURIFIER +------------------------ +Download and unzip HTML Purifier <htmlpurifier.org>. Place the contents of +the library/ folder in the htmlpurifier/htmlpurifier folder. Your directory +structure will look like: + +phorum/ + mods/ + htmlpurifier/ + htmlpurifier/ + HTMLPurifier.auto.php + ... - other files + HTMLPurifier/ + +Advanced users: + If you have HTML Purifier installed elsewhere on your server, + all you need is an HTMLPurifier.auto.php file in the library folder which + includes the HTMLPurifier.auto.php file in your install. + +4. MIGRATE +---------- +If you're setting up a new Phorum installation, all you need to do is create +a blank migrate.php file in the htmlpurifier module folder (NOT the library +folder. + +If you have an old Phorum installation and was using BBCode, +copy migrate.bbcode.php to migrate.php.

ENABLE +--------- +Navigate to your Phorum admin panel at http://example.com/phorum/admin.php, +click on Global Settings > Modules, scroll to "HTML Purifier Phorum Mod" and +turn it On. + +6. MIGRATE SIGNATURES +--------------------- +If you're setting up a new Phorum installation, skip this step. + +If you allowed your users to make signatures, navigate to the module settings +page of HTML Purifier (Global Settings > Modules > HTML Purifier Phorum Mod > +Configure), type in "yes" in the "Confirm" box, and press "Migrate." + +ONLY DO THIS ONCE!

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. HTML Purifier is smart and will +not re-migrate already processed messages. However, the original code +is irretrievably lost (we may change this in the future.) + +This module will not automatically migrate user signatures, because this +process may take a long time. After installing the HTML Purifier module and +then configuring 'migrate.php', navigate to Settings and click 'Migrate +Signatures' to migrate all user signatures to HTML. + +All of HTML Purifier's usual functions are configurable via the mod settings +page.
