Modifying BP Class output with an add_action function

    I have been developing this plugin for a while now, and was actually running until the new version of BP came out, then alot of thins broke. But mostly it was my poor coding. I hard coded changes in BP and on upgrade VOILA!! I knew that. So anyway moving on and getting alot better at WP and BP plugin development. I have made my plugins more BP and WP aware when possible and also theme aware.

    I am trying to slightly modify the out put of the bp_has_groups template tag by adding an extra SQL query to the BP_Groups_Groups:get_active function. I have easily modified out put of functions outside the BP Objected Oriented classes with “add_action” But I am having difficulty doing the same for functions called inside the BP classes.

    currently (and this works) I have the coded appended to the bottom of the get_active function
    ` if ( $bp->current_component == $bp->schools->slug && !empty($bp->current_action ) && !empty($bp->action_variables[0] ) && !empty($bp->action_variables[1] ) ){

    $browse_sql = “AND m.city_id = ‘$city_id'”;
    $paged_groups = $wpdb->get_results( “SELECT g.*, gm1.meta_value as total_member_count, gm2.meta_value as last_activity FROM {$bp->groups->table_name_groupmeta} gm1, {$bp->groups->table_name_groupmeta} gm2, {$bp->schools->table_name} m, {$bp->groups->table_name} g WHERE g.id = m.group_id AND g.id = gm1.group_id AND g.id = gm2.group_id AND gm2.meta_key = ‘last_activity’ AND gm1.meta_key = ‘total_member_count’ {$browse_sql} {$hidden_sql} {$search_sql} ORDER BY last_activity DESC {$pag_sql}” );
    $total_groups = $wpdb->get_var( “SELECT COUNT(DISTINCT m.group_id) FROM {$bp->schools->table_name} m LEFT JOIN {$bp->groups->table_name_groupmeta} gm ON m.group_id = gm.group_id INNER JOIN {$bp->groups->table_name} g ON m.group_id = g.id WHERE gm.meta_key = ‘last_activity’ {$browse_sql} {$hidden_sql} {$search_sql} ” );

    }`

    On future upgrades this little line will be overwritten (I have a handy dandy copy to put it right back) but I’d rather not especially if I will be releasing this to the public.

    I would like some help in getting this into a function and calling that function using the
    `add_action( $tag, $function_to_add, $priority, $accepted_args );`

    From the W Codex
    $function_to_add
    (callback) (required) The name of the function you wish to be called. Note: any of the syntaxes explained in the PHP documentation for the ‘callback’ type are valid.
    Default: None

    Am hoping @travel-junkie cna check this out, he’s been a great help before. Any help is appreciated

    seems in this special case you want an apply_filters in place of the {$browse_sql} var, then at least you can move the logic and sql code to that called function.

    though you will always need to copy it back during any upgrade since it is a core file – you could create your own patch file to run each time

    @nuprn1 thats a nice idea, I don’t know about the apply_filter though. the `$browse_sql` var is a new var that I initiate in just that function and within the scope of the if statement. Reasons being I added a whole other table to be queried in `$paged_groups` and `$total_groups` array being returned by the `get_active` function.

    Its a small line of code, easily replaced on upgrade and works perfectly fine for me right now, I just wanted to be able to access, append/modify and object oriented class function from an outside function (that doesn’t make sense) lol. Something like whatever I have in my what if statement gets its own function and the arguments from the get_active function and processes my query after get active is complete (sorta), its not a private function so I can access it outside the BP_Groups_Group class, just don’t know how I can do an add_action or an apply_filter

    If you’re making a change to BP_Groups_Groups:get_active(), I would recommend doing what Rich says and coding an alternative group get function by filtering “groups_get_groups” (available in the groups_get_groups() function in bp-groups.php).

    That way, you won’t have to hack the bp-groups-classes.php file in the future. It is more work, but it’s up to you.

    @r-a-y Thats sounds a little better, I thought I would have to filter the `bp_has_groups` function, I guess I didn’t quite figure the code out. I’ll try that. Thank you everybody let you know how it goes

    @nuprn1 @r-a-y Just a little update,

    Finally got around to it, actually the lastest Buddypress update kinda forced me to and it worked like a charm. I had to educate my self on wordpress’s apply_filters and add_filters.

    I wrote a custum function that filtered the results of the groups_get_groups function, basically removing my “handy dandy” code from the core files into my cutome plugin class file. Thanks for all your help.

    Good to know you figured it out!
    BuddyPress has forced me to learn a lot more about WordPress as well. A win-win!
