here is the relevant co

Answer 1

Here's one possible solution, I think there are probably others. Create an empty query builder with the query() function and add the non-null clauses to it, then call the paginate() function at the end.

$builder = Dogs::query();
if (Input::has('search')) {
    $queryString = Input::get('search');
    $builder->where('name', 'LIKE', "%$queryString%");
}
// ... more clauses from the querystring
$dogs = $builder->orderBy('name')->paginate(5);

You can use query scopes http://laravel.com/docs/eloquent#query-scopes to make it verbose and easier in your controller (or wherever you will be doing it in future) then chain them according to your needs:

// Dog model
public function scopeSearchBreed($query, $breed)
{
  $query->whereHas('breed', function ($q) use ($breed) {
    $q->where('name', 'like', "%{$breed}%");
  });
}

public function scopeWithinRadius($query, $radius)
{
  $query->where(...); // do math here
}

Then all you need is this:

public function index()
{
  $q = Dog::query();

  if (Input::has('search'))
  {
     // simple where here or another scope, whatever you like
     $q->where('name','like',Input::get('search'));
  }

  if (Input::has('search-breed'))
  {
     $q->searchBreed(Input::get('search-breed'));
  }

  if (Input::has('sex'))
  {
     $q->where('sex', Input::get('sex'));
  }

  if (Input::has('radius'))
  {
     $q->withinRadius(Input::get('radius'));
  }

  $dogs = $q->orderBy(..)->paginate(5);

  // ...

$builder = Dogs::query();
$term = Request::all();
if(!empty($term['breed'])){
    $builder->where('breed','=',$term['breed']);
}
if(!empty($term['sex'])){
    $builder->where('sex','=',$term['sex']);
}
if(!empty($term['radius'])){
    $builder->where('radius','=',$term['radius']);
}

$result = $builder->orderBy('id')->get();
