How do I execute a whereIN query in Laravel?

I am trying to execute a request whereIN

in Laravel. The value I want to match is the value from the database table, for example: "a, b, c, d"

I want to select all users who have a name that is in this line above. So I take a string and explode it to create an array and then add that array to the Laravel command. The problem is that it only returns one user that only matches the letter "a" and it stops.

Controller code:

public function returnEorti(){

    $month = Input::get('month');
    $day = Input::get('day');

    $eorti = DB::select("select text from days where day='$day' and month='$month'");
    $eortiFinal = explode(",", $eorti[0]->text);
    $pelatis = Pelatis::whereIn('Onoma', $eortiFinal)->get();

    return json_encode($pelatis);
}

      

        
        
        
      

    

ajax:

 $.ajax({
    type:"GET",
    url:"getEorti",
    data:{"day":d[2],"month":d[1]},
    success:function(data){
        var b = jQuery.parseJSON(data)
        for(var i=0;i<Object.keys(b).length;i++){
            $( "#test" ).append( b[i].Onoma+'</br>' );
        }      
        console.log(data);      
    }            
 });

      

        
        
        
      

    

And my route:

Route::get('getEorti','EortologioController@returnEorti');
