What version of Elgg? 1.7 or 1.8

It's 1.8

The proper way of doing it:

1. Create a new plugin (see documentation for details)

2. Register a plugin hook

elgg_register_plugin_hook_handler('creating', 'river', 'my_river_hook');

function my_river_hook($hook, $type, $return, $params) {

$remove_subtypes = array('hjeducation', 'hjexperience', 'hjskill', 'hjlanguage');

$subtype = elgg_extract('subtype', $params, false);

if ($subtype && in_array($subtype, $remove_subtypes)) {

return false;

}

return true;

}

The above will register a hook for the following trigger found in engine/lib/river.php:

$params = array(

'type' => $type,

'subtype' => $subtype,

'action_type' => $action_type,

'access_id' => $access_id,

'view' => $view,

'subject_guid' => $subject_guid,

'object_guid' => $object_guid,

'annotation_id' => $annotation_id,

'posted' => $posted,

);

// return false to stop insert

$params = elgg_trigger_plugin_hook('creating', 'river', null, $params);

if ($params == false) {

// inserting did not fail - it was just prevented

return true;

}

Every time the plugin is attempting to add an item to a river with a subtype added to the array $remove_subtypes, your hook will prevent that action.

@Ismayil:

Thanks for the reminder that your posted code points me to ;-)

I was planning to pull Elgg-community_customizations
to do some simple patches to block 'junk' kind of stuff on the river - people :-
-- Making so-o-o many fiends - clogging the Comm River,
-- Updating their Profiles umpteem times in several minutes,
-- Updating their Avatars umpteem times in several minutes,
and that sort of ckunky stuff that clouds the River when we're loooking
for some juicy *technical posts `n stuff.

Funny thing is that after coding those changess --
I seem to 'lost' all my code..
Somewhere on my Desktop or Drive C: or XAMPP'shtdocs ;-P 
and so I gonna have to code all that again ! ;-(

But PlZ - nobody laugh at my sloppiness !
I'm the kinda Developer that has 500+ items on my Desktop
and a few hunderd scattered on XAMPP ;-oO;X

But thanks to your reference to the
'elgg_register_plugin_hook_handler('creating', 'river', ..
I kinda remember most of that lost code ;-)
And so back working on that code..
and maybe soon gotta do my 'newbie' struggles
with GitHub Web interface + Git GUI stuffs.

:) Just realized that you might want to be a little more attentive when you do this than I am while posting my previous post. Of course, you need to return $params, not true.

Yep ;-) & ThX - I caught that ;)

You forgot to initialize your plugin :)

elgg_register_event_handler('init', 'system', 'activityStreamEdit_init');

function activityStreamEdit_init() {

    elgg_register_plugin_hook_handler('creating', 'river', 'my_river_hook');

}

function my_river_hook($hook, $type, $return, $params) {

    $remove_subtypes = array('hjeducation', 'hjexperience', 'hjskill', 'hjlanguage', 'hjportfoliofile');

    $subtype = elgg_extract('subtype', $params, false);

    if ($subtype && in_array($subtype, $remove_subtypes)) {

        return false;

    }

    return $return;

}

@JF:
Now thatsh wot I likes to see ;)
Someone newbie-like looking but not
afraid to roll sleeves and just try N test out code..
In my good books..;-P

@Dhrup thanks alot :)

But unfortunately the posts are still going to the activity stream in the dashboard :(

I even deactivated anad re-activated the plugin.
