jquery - how to call model from joomla layout passing an object -


how call joomlas layout models method gather data? try use google maps on lat , long , on search retrieved object contains specified datas, , layout initialise data desired xml follows. know not best workaround not same query twice.

controller calling model

            $model = $this->getmodel('item');             $view = $this->getview('item', 'html'); // view             $view->setlayout('default:items');             $view->assignref('url_var', $this->input->get('state'));             $view->assignref('city', $this->input->get('city'));

view.html

    function display($tpl = null)      {             // assign data view                    $this->item_list = $this->get(items, $this->city);              $this->xml_map = $this->get(createmapxml, $this->item_list);             //here not queries object list.shows me passed id want pass model argument             var_dump($this->get(items, $this->city));    // check errors.             if (count($errors = $this->get('errors')))              {                     jlog::add(implode('<br />', $errors), jlog::warning, 'jerror');                     return false;             }             // display view             parent::display($tpl);

}

var mark;   var pointa;    if (gbrowseriscompatible()) {     var m = jquery("#map")[0];     if(m) {        var map = new gmap2(m);       var start = new glatlng(63.13450320833446,16.69921875);       var zoomlevel = 5;       map.setcenter(start, zoomlevel);       map.addcontrol(new gsmallmapcontrol());  //here create xml calling model function       jquery.get('<?php //$model->createmapxml($this->items)?>',function(data) {       jquery(data).find('marker').each(function(){           var lat    = jquery(this).attr('lat');           var lng    = jquery(this).attr('lng');           var html   = jquery(this).attr('name')+" ";           html      += jquery(this).attr('msg')+" ";           html      += jquery(this).attr('link');           var point  = new glatlng(lat,lng);           var marker = new gmarker(point);            map.addoverlay(marker);            gevent.addlistener(marker, "click", function() {             marker.openinfowindowhtml(html);           });          });        });        gevent.addlistener(map, 'click', function(overlay, point){         if(mark) {           map.removeoverlay(mark);         }         if(point) {           pointa = new gpoint(point.x, point.y);           mark = new gmarker(pointa);           map.addoverlay(mark);           map.getcenter(point);           var lat = point.y;           var lng = point.x;            map.openinfowindowhtml(point,form);         }       });     }   }

the layout loading through view.html.php . model included in view.html.php means inside layout can access model function classname :: functionname();

another option can assign model in view.html.php variable like

$this->assignref("product_model",$model);

then on layout can access 

$this->product_model->function();

hope you.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
