Laravel 5.4-从数组集合产品分页

Question

i'm trying to paginate a collection's products, like this:

$products_array = array();

        for ($i=0; $i < count($t); $i++) { 

            $p = Product::where('category_id',$t[$i]->category_default)->where('project_id',$t[$i]->id)->first();
            array_push($products_array, $p);
        }

        $paginate = new Illuminate\Pagination\LengthAwarePaginator($products_array, count($products_array), 10, 1, ['path'=>url('api/products')]);

        dd($paginate);

But i get this error:

FatalThrowableError in HomeController.php line 75: Class 'Shop\\Http\\Controllers\\Illuminate\\Pagination\\LengthAwarePaginator' not found

i don't know if this is the best way to do this, I would appreciate your help.

Answer 1

The error is really self explaining. You are trying to use Illuminate\\Pagination\\LengthAwarePaginator from current namespace and this is Shop\\Http\\Controllers .

To fix this, either add leading backslash like so:

$paginate = new \Illuminate\Pagination\LengthAwarePaginator($products_array, count($products_array), 10, 1, ['path'=>url('api/products')]);

or at the beginning of this PHP file (after opening PHP tag) add new line:

use Illuminate\Pagination\LengthAwarePaginator;

and then you can write above line like so:

$paginate = new LengthAwarePaginator($products_array, count($products_array), 10, 1, ['path'=>url('api/products')]);
