How to add a filter for the RSS feed.

posts: 214

Warning, the following suggests making changes to Tiki code, use at your own risk.

There isn't currently an external feed filter option. You could make the code change below to add one.

Create a tracker, name does not matter, keep the tracker ID number.
Add a field to the tracker, Type: Text field, name does not matter, keep the field ID number.
Use this tracker to hold the filter strings.

At the top of lib/rss/rsslib.php, before the lines:

Copy to clipboard
class RSSLib extends TikiDb_Bridge {


Add these lines so it looks like:

Copy to clipboard
global $rssfilterwordlist; $rssfilterwordlist = TikiLib::lib('trk')->get_all_items("tracker id number","field id number",'opc'); class RSSLib extends TikiDb_Bridge {

Put your Tracker id number where it has "tracker id number" and field id number where it has "field id number".

Then in the function, insert_item, change these lines:

Copy to clipboard
private function insert_item( $rssId, $data, $actions ) { $this->items->insert(

to

Copy to clipboard
private function insert_item( $rssId, $data, $actions ) { global $rssfilterwordlist; foreach ($rssfilterwordlist as $filterword) { if (strpos($data['description']." ".$data['title'], $filterword) !== FALSE) { return; }} $this->items->insert(


Insert the word(s) you want to filter in the tracker.

Filter is case sensitive. Be careful, the filter word will be matched even if it is part on another word, "election" will reject "selection".
Padding filter words with space does not work, but you can have multiple words with spaces in between them as a filter word.

The code above applies the filter to both the "title" and "description". You could change it to "strpos($data['title'], $filterword)", if you only want the filter words applied to the "title", or "strpos($data['description'], $filterword)" , if you only want the filter words applied to the description.

I think this will work in Tiki 9 through Tiki 15, but I only tested it on Tiki 14.
