Setting up Google map pans in Code igniter with BIOSTALL google map library

Question

I learned from this thread that setting up google map pan is pretty simple Job in Java script using google map API.

Unfortunately I am not good in Java Script and my project is in Codeigniter I used BIOSTALL google map library for Codeigniter which is working excellent (Thanks to BIOSTALL) but now I am stuck with one last thing and that is defining map pans and setting the zoom dynamically. I wonder if someone has experience in it and can guide me how to do that in codeigniter.

I have to display all map markers which are returned from search query. Following is my code to collect markers and create map

    $zip_codes=$this->search_model->get_zip_codes();

    for($i=0;$i<count($zip_codes);$i++)
    {
        $data['marker_items']=$this->search_model->get_items_by_zip_code($data['search'],$zip_codes[$i]['zip']);
        $marker = array();
        $marker['position'] = $data['marker_items'][0]['latitude'].','.$data['marker_items'][0]['longitude'];
        $map_markers=$this->load->view('map_marker',$data,true);
        $marker['infowindow_content']=$map_markers;
        $marker['icon'] = 'http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld='.count($data['marker_items']).'|3399FF|000000';
        $this->googlemaps->add_marker($marker);
    }
    $data['map'] = $this->googlemaps->create_map();

I get map center coordinates by two ways;

• If the user is logged in . Get his coordinates from his address
• If the user is logged out. Get his coordinates from his IP address.

Will appreciate any kind of help. Thanks

You can use the $config['zoom'] = 'auto'; It'll act like the fitbound function of the JS map library.

You can also set he minimum zoom level to get the not very deep zoom and for good user experience.
