Question

您好我做了一个Laravel项目，我可以通过排序查看一些记录。例如，我有一个带URL的交付页面

http://localhost/dboard/public/deliverytracker

在该表单中，有“从日期”和“到”日期以在查询之前对数据进行排序。当我点击提交时，数据会被渲染，并且分页链接就在那里。但是，当点击时，例如

的分页的第2页

http://localhost/dboard/public/deliverytracker?page=2

在链接中它不会呈现数据的第2页。它只是重新加载页面，我需要再次选择从日期和日期，然后再次单击提交。我错过了什么吗？

这是我的路线

/* Delivery Tracker */
Route::get('deliverytracker', 'DeliveryTrackerController@deliveryIndex');
Route::post('deliverytracker', 'DeliveryTrackerController@getDeliveries');

我提交表格时的功能

public function getDeliveries()
{
    $rules = array(
        'fromdate'  => 'required',
        'todate'    => 'required',
    );

    $validator = Validator::make(Input::all(), $rules);

    // Check if all fields is filled
    if ($validator->fails()) 
    {
        return Redirect::to('deliverytracker')->withErrors($validator);
    }
    else
    {
        $from   = Input::get('fromdate');
        $to     = Input::get('todate');

        $deliveries = new DeliveryTracking();
        $result = $deliveries->getDeliveries($from, $to);

        // Get the current page from the url if it's not set default to 1
        $page = Input::get('page', 1); 

        // Number of items per page
        $perPage = 5;

        // Start displaying items from this number;
        $offSet = ($page * $perPage) - $perPage; // Start displaying items from this number

        // Get only the items you need using array_slice (only get 10 items since that's what you need)
        $itemsForCurrentPage = array_slice($result, $offSet, $perPage, true);

        // Return the paginator with only 10 items but with the count of all items and set the it on the correct page
        $result =  new LengthAwarePaginator($itemsForCurrentPage, count($result), $perPage, $page);
        $result->setPath('deliverytracker');

        return view('deliverytracker.index')->with(array('result' => $result));

    }

}

我的观点

<div class="panel-body">
                @if(isset($result))
                    <table class="table table-striped table-bordered">

Answer 1

在您的帖子中，您提到第二页仅使用?page=N进行调用，看到您的路线定义为GET和POST，您将点击{{1}的路线定义点击下一页链接。

页面按钮只是链接而不是POST表单。因此，不是点击GET，而是点击getDeliveries()。

您也可以考虑将fromdate和todate附加到您的分页链接;见Appending To Pagination Links

Answer 2

表单字段（fromdate，todate）不会自动附加到分页。您需要使用 - ＆gt; append（）方法将查询字符串值添加到paginator。

// Return the paginator with only 10 items but with the count of all items and set the it on the correct page
$result =  new LengthAwarePaginator($itemsForCurrentPage, count($result), $perPage, $page);
$result->setPath('deliverytracker');
$result->appends(['fromdate' => $from, 'todate' => $todate]);
