getPaginationCount() function not working in Laravel's Eloquent ORM

Question

I'm pulling out the Eloquent module to use it separately, but I have access to the QueryBuilder functions. They're all working except for that one.

When I run a count() and a getPaginationCount(), the count() returns the correct value, but getPaginationCount() just returns the Illuminate\\Database\\Eloquent\\Builder object, as if I didn't command a query to run. However, I can see 2 queries in the query log, and oddly, they both run the same query.

require 'vendor/autoload.php';  

use Illuminate\Database\Capsule\Manager as Capsule;  

$capsule = new Capsule;

$capsule->addConnection(array(
    'driver'    => 'mysql',
    'host'      => TECHDB_HOST,
    'database'  => TECHDB_DBNAME,
    'username'  => TECHDB_USER,
    'password'  => TECHDB_PASS,
    'charset'   => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix'    => ''
));

$capsule->bootEloquent();


class Indicator extends Illuminate\Database\Eloquent\Model {
    public $timestamps = false;
    public $table = "indicator_performance";
}

$query = Indicator::where('symbol', '=', 'IBM')->forPage(1,2);

var_dump($query->count()); //Correctly prints '13'

var_dump($query->getPaginationCount()); //dumps the 'Illuminate\Database\Eloquent\Builder' object

Here is the query log:

array (size=2)
  0 => 
    array (size=3)
      'query' => string 'select count(*) as aggregate from `indicator_performance` where `symbol` = ? limit 2 offset 0' (length=93)
      'bindings' => 
        array (size=1)
          0 => string 'IBM' (length=3)
      'time' => float 4.85
  1 => 
    array (size=3)
      'query' => string 'select count(*) as aggregate from `indicator_performance` where `symbol` = ? limit 2 offset 0' (length=93)
      'bindings' => 
        array (size=1)
          0 => string 'IBM' (length=3)
      'time' => float 4.24

EDIT:

It seems I've exposed a more general bug with the count() function when used after a forPage() call. Have a look at these results:

$query = Indicator::where('symbol', '=', 'IBM');

var_dump($query->count()); //Correctly returns '13'
var_dump($query->forPage(0, 5)->count()); //Correctly returns '13'
var_dump($query->forPage(1, 5)->count()); //Correctly returns '13'
var_dump($query->forPage(2, 5)->count()); //Returns null. Should return '13' or '3', depending on implementation.

There are 2 problems with your code (and the Laravel):

1. getPaginationCount() called on the Eloquent Builder runs the method (on the Query Builder class) but doesn't return its result. Instead it returns itself as $this .

2. getPaginationCount() doesn't reset limit and offset on the query to get the count, which I suppose is a bug. This results in returning null whenever offset is set to anything higher than 1. forPage($page) will do that for $page > 1 .

That being said, I suggest you either use count() instead of getPaginationCount() or:

// first get the count
$count = $query->getQuery()  // get the base Query Builder directly
    ->getPaginationCount();  // in order to return the count

// then use forPage
$query->forPage(1,5);
