Laravel scope with binding

SomeModel.php

<?php

class SomeModel extends Eloquent
{
  public function scopeSomething(Builder $query, $something)
  {
    // This will properly set up a binding
    return $query->where('something', $something);
  }
  
  public function scopeSomethingAndOr(Builder $query, $something, $connector)
  {
    if ($connector == 'and') {
      return $query->where('something', $something);
    } else {
      return $query->orWhere('something', $something);
    }
    // Really, you can shorten this to the following:
    // return $query->where('something', '=', $something, $connector)
  }
}

I think my issue is that I need to use WHERE st_contains(bounds, POINT(:lat, :lng)

What I have is

                    ->whereRaw('search_type = :type AND st_contains(bounds, POINT(:lat, :lng))')
                    ->setBindings([
                        'type' => $type,
                        'lat' => $lat,
                        'lng' => $lng
                    ]);

However, when I combine it with another scope that uses SELECT st_distance(location, POINT(:latDistance, :lngDistance)) as distance I get an error for incorrect number of parameters. I assume this is because the scope wipes out the previous bindings.

If I use $query->getBindings() with an array merge, it returns a numerically indexed array, without the keys I previously set. This then makes PDO complain about mixed named and numeric parameters.

If I change all my queries to use ? instead of named parameters, Laravel sets them in the wrong order :/.

Additionally, if I mix a scope like the one above with another one as simple as return $query->where('search_type', 'proximity');, the mixed named and positional parameters error returns.

Hmm, whereRaw accepts a second parameter called bindings: https://github.com/laravel/framework/blob/c858d541b1a05c3a13734c17f5d9e69fe6e1502b/src/Illuminate/Database/Query/Builder.php#L564

You should try that (with numeric indices and question marks as placeholders, yes).
