Good morning Michael
the SearchPost component is ready. it works correctly, it allows the search in all posts of the website without displaying the 'friends only' posts of members who are not friends. Can you show me where I can upload it to Github? I just created an account there and really the many buttons and links make me dizzy, I don't know where to go

ah, I didn't know that it could cause conflict.. I'm going as you told me

Without having a closer look into it:
Adding something to other component's or even core's classes is a no-go :))
This would introduce dependencies nobody wants to fight with.
So, implement it as a new SearchPost class, extending what you need (OssnWall or maybe OssnObject) like
class SearchPosts extends OssnObject { .....

PART 2

$options = array_merge($default, $params);
                    $attrs   = ossn_call_hook('wall', 'getFriendsPosts', $extra_param, $options);
                    $default_public = array(
                            'type'           => 'user',
                            'subtype'        => 'wall',
                            'order_by'       => 'o.guid DESC',
                            'entities_pairs' => array(
                                    array(
                                            'name'   => 'access',
                                            'value'  => true,
                                            'wheres' => '(1=1)',
                                    ),
                                    array(
                                            'name'   => 'poster_guid',
                                            'value'  => true,
                                            'wheres' => "((emd0.value=2) OR (emd0.value=3 AND [this].value IN({$friend_guids})))",
                                    ),

                            ),
                    );      
                    $extra_param_public = array(
                            'friends_guids' => $friend_guids,
                            'user'          => $user,
                    );
                    $options_public = array_merge($default_public, $params);
                    $attrs_public   = ossn_call_hook('wall', 'getPublicPosts', $extra_param_public, $options_public);

                    $attrs = array_merge($attrs, $attrs_public);

                    return $this->searchObject_posts($attrs);
            }
            return false;
    }

As I'm not experienced in Github I'm going to split the SearchPosts() function here in two parts (a bit extreme solution and sorry to have damaged the page by this kind of distributed comments). the SearchPosts() function to add in OssnWall/Classes.

PART1

public function SearchPosts($params = array()){
            $user = ossn_loggedin_user();
            if(isset($user->guid) && !empty($user->guid)){
                    $friends = $user->getFriends();
                    //operator not supported for strings #999
                    $friend_guids = array();
                    if($friends){
                            foreach ($friends as $friend){
                                    $friend_guids[] = $friend->guid;
                            }
                    }                       
                    $friend_guids[] = $user->guid;
                    $admins = ossn_get_admin_users();
                    if($admins){
                            foreach ($admins as $item){
                                    if(!in_array($item->guid, $friend_guids)){
                                            $friend_guids[] = $item->guid;
                                    }
                            }
                    }               
                    $friend_guids = implode(',', $friend_guids);
                    $default = array(
                            'type'           => 'user',
                            'subtype'        => 'wall',
                            'order_by'       => 'o.guid DESC',
                            'entities_pairs' => array(
                                    array(
                                            'name'   => 'access',
                                            'value'  => true,
                                            'wheres' => '(1=1)',
                                    ),
                                    array(
                                            'name'   => 'poster_guid',
                                            'value'  => true,
                                            'wheres' => "((emd0.value=2 OR emd0.value=3) AND [this].value IN({$friend_guids}))",
                                    ),
                            ),
                    );

                    $extra_param = array(
                            'friends_guids' => $friend_guids,
                            'user'          => $user,
                    );

yes, this forum isn't really meant for posting longer program code - I'd suggest to put the complete component onto Github instead.

I try to share the function SearchPosts($params = array()) but the site answers me 'Can't apply comment I don't know how to share it. in reality the SearchPosts() function is a mix of the two already existing functions getFriendsPosts() and getPublicPosts()

I think I found a solution but that requires your approval of course. I modified the ossn_com file as follows:

    $wall = new OssnWall;
    $query = input('q');
    $search_options = array("search_type" => true, "description" => $query, 'type' => 'user',
            'distinct' => true);

    //if not admin user add where caluse to limit reach
    if(!ossn_isAdminLoggedin()){

    $posts = $wall->SearchPosts($search_options);       
    $search_options['count'] = true;      
    $count = $wall->SearchPosts($search_options);

    }else{

$posts = $wall->getAllPosts(array('search_type' => true,
                                    'description' => $query,
                                    'type' => 'user',
                                    'distinct' => true));
$count = $wall->getAllPosts(array(
        'search_type' => true,
        'description' => $query,
        'type' => 'user',
        'distinct' => true,
        'count' => true,

));     


    }

    $found['users'] = $posts;
    $search = ossn_plugin_view('searchposts/search/view', $found);
    $search .= ossn_view_pagination($count);
    if(empty($posts)) {
        return ossn_print('ossn:search:no:result');
     }
        return $search;

I will do my best. If I find a reliable solution, I will not hesitate to share it

Melo,
I might be wrong, but it seems that Jason discontinued working on this component. So could YOU provide a fix perhaps?
