Laravel

Question

所以我在我的 Laravel 项目上添加了带 Ajax 的 daterangepicker，在我的 blade 上我有像日历一样的 daterangepicker 来选择日期并刷新 filter.Now我单击刷新它刷新我当前选择的日期但是当我什么都不过滤时 happens.When 我在我的 Safari 浏览器上检查元素它显示：无法加载资源：服务器响应状态为 500（内部服务器错误）。

这是我的 DateRangeController

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use DB;
use App\Post;
use Auth;

class DateRangeController extends Controller
{
    public function index()
    {
        $posts = Post::where('user_id', Auth::id());
        return view('daterange')->with('posts', $posts);
    }

    public function fetch_data(Request $request)
    {
     if($request->ajax())
     {
      if($request->from_date != '' && $request->to_date != '')
      {
       $data = DB::table('posts')
         ->whereBetween('date', array($request->from_date, $request->to_date))
         ->get();
      }
      else
      {
       $data = DB::table('posts')->orderBy('date', 'desc')->get();
      }
      echo json_encode($data);
     }
    }
}

?>

这是我的 daterange.blade.php 和脚本

   alert('Both Date is required');
  }
 });

 $('#refresh').click(function(){
  $('#from_date').val('');
  $('#to_date').val('');
  fetch_data();
 });


});
</script>

这是我的 daterange

路线

Route::get('/daterange', 'DateRangeController@index');
Route::post('/daterange/fetch_data', 'DateRangeController@fetch_data')->name('daterange.fetch_data');

这个问题有什么解决办法吗？它需要显示所选日期

的帖子

Answer 1

我将其全部修复为 created_at，而不是日期，现在我的 DateRangeController 看起来像这样：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use DB;
use App\Post;
use Auth;

class DateRangeController extends Controller
{
    public function index()
    {
        $posts = Post::where('user_id', Auth::id());
        return view('daterange')->with('posts', $posts);
    }

    public function fetch_data(Request $request)
    {
     if($request->ajax())
     {
      if($request->from_created_at != '' && $request->to_created_at != '')
      {
       $data = DB::table('posts')
         ->whereBetween('created_at', array($request->from_created_at, $request->to_created_at))
         ->get();
      }
      else
      {
       $data = DB::table('posts')->orderBy('created_at', 'desc')->get();
      }
      return json_encode($data);
     }
    }
}

?>

它 returns 我现在所有的帖子，但它喜欢未定义，并且在网络上 url 请求它 returns 我是真实的，而不是未定义的。有什么解决办法吗？

你的成功功能问题，你试试 handle 属性 not found, 这是完整的脚本标签


<script>
    var _token = $('input[name="_token"]').val();
    $(document).ready(function(){

 var date = new Date();

 $('.input-daterange').datepicker({
  todayBtn: 'linked',
  format: 'yyyy-mm-dd',
  autoclose: true
 });


 //if you leave this ,will load the data if you remove this  remove comment  from line number 43 to 49 to load data :)
        fetch_data();


 $('#filter').click(function(){
  var from_date = $('#from_date').val();
  var to_date = $('#to_date').val();
  if(from_date != '' &&  to_date != '')
  {
   fetch_data(from_date, to_date);
  }
  else
  {
   alert('Both Date is required');
  }
 });

 $('#refresh').click(function(){
  $('#from_date').val('');
  $('#to_date').val('');
  fetch_data();
 });


});
function fetch_data(from_date = '', to_date = '')
{
    $.ajax({
        url:"{{ route('daterange.fetch_data') }}",
        method:"POST",
        data:{from_date:from_date, to_date:to_date, _token:_token},
        dataType:"json",
        success:function(data)
        {
            var output = '';
            $('#total_records').text(data.length);
            $.each(data,function (key,value) {
                console.log(value)
                output += '<tr>';
                output += '<td>' + value.br_kesice + '</td>';
                output += '<td>' + value.ime + '</td>';
                output += '<td>' + value.created_at + '</td></tr>';
            });
            $('tbody').html(output);
        }
    })
}
</script>

删除存储库，祝你的项目好运:)
