Laravel表过滤器

Question

So I have website based on Laravel framework. I have table and the filter for table to filter the items - http://prntscr.com/ccht0f.

When I filter them by anything all works good, but when I change the page filtering disapers from session. http://prntscr.com/cchutt - http://prntscr.com/cchuyo. Looks like pagination destroys all sessions.

My code:

public function filters(Request $request)
{
    $filter_item_acquisition_forms = [null];
    $filter_collections = [null];
    $filter_origin_dates = [null];

    $order_by = request()->query('order_by', 'id');
    $dir = request()->query('dir', 'desc');

    $storage_items = StorageItem::with(
        'authorClassification',
        'placeClassification',
        'classificationValueOrigin',
        'classificationValueOriginDate',
        'classificationValueItemAcquisitionForm',
        'classificationValueCollection',
        'classificationValuesMaterials',
        'classificationValuesTechnique',
        'employeeClassificationsRestorers',
        'userLastUpdatedBy.employeeClassification',
        'userResponsibleUser.employeeClassification',
        'attachments'
    );

    $storage_items = $storage_items->id($request->filter_id)
        ->acceptanceId($request->filter_acceptance_id)
        ->acceptanceNumber($request->filter_acceptance_number)
        ->acceptanceDate($request->filter_acceptance_date)
        ->mainInventoryNumber($request->filter_main_inventory_number_from, $request->filter_main_inventory_number_to)
        ->scientificInventoryNumber($request->filter_scientific_inventory_number)
        ->imageInventoryNumber($request->filter_image_inventory_number)
        ->itemCosts($request->filter_item_costs_from, $request->filter_item_costs_to)
        ->originDate($request->filter_origin_date)
        ->updatedAt($request->filter_updated_at_from, $request->filter_updated_at_to)
        ->addingDate($request->filter_added_from, $request->filter_added_to)
        ->itemAcquisitionForm($request->filter_item_acquisition_form)
        ->collection($request->filter_collection)
        ->employee($request->filter_employee)
        ->isInExposition($request->filter_is_in_exposition)
        ->isRestored($request->filter_is_restored)
        ->haveAttachments($request->filter_have_attachments)
        ->haveNotCosts($request->filter_have_not_costs)
        ->searchInField($request->filter_search_in_field, $request->filter_word_or_phrase);




    $storage_items = $storage_items->orderBy($order_by, $dir)->paginate(20);

    foreach ($storage_items as $storage_item) {
        if ($storage_item->classificationValueItemAcquisitionForm != null) {
            $filter_item_acquisition_forms[$storage_item->classificationValueItemAcquisitionForm->id] = $storage_item->classificationValueItemAcquisitionForm->value;
        }

        if ($storage_item->classificationValueCollection != null) {
            $filter_collections[$storage_item->classificationValueCollection->id] = $storage_item->classificationValueCollection->value;
        }

        if (!is_null($storage_item->classificationValueOriginDate)) {
            $filter_origin_date[$storage_item->classificationValueOriginDate->id] = $storage_item->classificationValueOriginDate->value;
        }
    }
    $request->flash();

    return view('panel.storage_items.filters')->with([
        'storage_items' => $storage_items,
        'current_order_query' => compact('order_by', 'dir'),
        'employees' => [null] + EmployeeClassification::lists('employee', 'id')->toArray(),

            ]
        ]
    ]);
}

Answer 1

So I fixed it myself.

Solution: I got the collection ID from request and stored it in variable.

$filter_collection = $request->filter_collection;

Passed variable to the view

->with('filter_collection', $filter_collection)

And changed my pagination to pass collection ID to next page

{{ $storage_items->appends(['filter_collection' => $filter_collection])->links() }}
