在模型中的数据库查询生成器中使用控制器变量-Laravel

Question

At the moment i have Query inside my Controller method made using Query Builder. Like so:

 public function postFilters(){
    $filt = Input::get('name');
    $query = DB::table('wm.top_pages')->where('filter',$filt)->limit(20)->get();

    return View::make('topPages.table', ['wm'=>$query]);
} 

I would like to get the query outside of Controller and into my Model. But everytime i do this, i get an error because the same query as above, but now inside my model does not recognize the variable $filt, which actually gotten from my View. Can anyone advise on how to go about this? What i have done above is actually not what MVC should look like and i'm assuming there are ways of getting around it. I just cant make sense of most of the documentation on this specific topic.

Thanks a lot.

Well if I were you, I would create a Repository interface, and create an implementation to it, in this implementation I would add all my queries, and then the variable filter would be passed as an argument, then in my controller I would inject my interface (which is really simple using laravel). So I end up with an application which is extensible, if I ever want to switch from MySQL to another database all I have to do is to create a new implementation and configure laravel to use the new implementation. That's how I do it. if you want to learn more about the Repository pattern, here's a good article.

I do not know why you are sending a query to the model let whatever the reason be following is the code :

in your model

<?php 
 class SomeModel extends Eloquent
 {
 public static function funcname($filter,$data)
 {
 // the filter passed from controller is in $filter
 }
 }

in your controller

 $filt = Input::get('name');
 $query = DB::table('wm.top_pages')->where('filter',$filt)->limit(20)->get();

 //pass the data from this controller to funcname function we created in model
 SomeModel::funcname($filt,$query);

Thanks to @Elias Van Ootegem:

I passed on the variable as a parameter/argument to the model function and it worked. Controller:

 public function postFilters(){
   $filt = Input::get('name');
   $query = webmasters::getFilters($filt);
   return View::make('topPages.table', ['webmasters'=>$query]);
 } 

Model:

class webmasters {
   public static function web($filt) {
   $top_pages = DB::table('wm.top_pages')->where('filter',$filt)->limit(20)->get();
   return $top_pages;
}

}
