Laravel 在 1 个标题下显示同一日期的所有职位
我创建了一个表格，将日期显示为标题，然后在其下方显示当天的工作。但是，当我在同一天有两项工作时，它会在每项工作下方显示两次日期。我想在 1 个日期（标题）下一起显示当天的所有作业。
<table>
<tbody>
@foreach($loads as $load)
<tr><td colspan="8" class="ml-1 h4 text-warning">{{date('l, d-F-Y', strtotime($load->pickup_date))}}</td></tr>
<tr>
<td>{{date("g:i a", strtotime($load->pick_up_time))}}</td>
<td><textarea>{{$user->customer}}</textarea></td>
<td>{{$load->pickup_location}}</td>
<td>{{$load->drop_off_location}}</td>
<!-- <td>{{$load->distance}}</td>-->
<!--<td><textarea>{{$load->description}}</textarea></td>-->
<!--<td>{{$load->customer_reference}}</td>-->
<td>{{$load->vehicle}}</td>
<td>{{$load->driver}}</td>
<td><textarea>{{$load->notes}}</textarea></td>
<td>
<a href="{{route('EditLoad',$load->id)}}" class="fa fa-2x fa-pencil-square-o" style="color:#FF6F00;"></i></a>
<a href="{{route('EditLoad',$load->id)}}" class="fa fa-2x fa-truck" style="color:#5cac00;"></i></a>
<a href="{{route('EditLoad',$load->id)}}" class="fa fa-2x fa-phone" style="color:#00b1e6;"></i></a></td>
</td>
</tr>
@endforeach

在控制器中： public function store(Request $request) { $originalDate = $request['pickup']; $PickUpDate = date("Y-m-d", strtotime($originalDate)); $originalDate = $request['destination']; $DestinationDate = date("Y-m-d", strtotime($originalDate)); $originalDate = $request['createdDate']; $createdDate = date("Y-m-d", strtotime($originalDate)); $load = new Load; $load->user_id = Auth::id(); $load->customer = $request['customer']; $load->pickup_date = $PickUpDate; $load->destination_date = $DestinationDate; $load->creation_date = $createdDate; $load->trailer = $request->trailer; $load->pickup_location = $request['pickup_location']; $load->drop_off_location = $request['drop_off_location']; $load->distance = $request['distance']; $load->description = $request['description']; $load->quantity = 1; $load->customer_reference = $request['customer_reference']; $load->load_number = $request['load_number']; $load->additional_details = $request['additional_details']; $load->vehicle = $request['vehicle']; $load->driver = $request['driver']; $load->notes = $request['notes']; $load->Rate = $request['rate']; $load->pick_up_time = $request['pickupTime']; $load->destination_time = $request['destinationTime']; $load->creation_time = $request['createdTime']; $load->consignee = $request['consignee']; $load->save(); return back()->with('Success', 'Load created successfully');} 在刀片中： <tbody> dd($loads); @foreach($loads as $key=>$new_load) <tr><td colspan="8" class="ml-1 h4 text-warning">{{date('l, d-F-Y', strtotime($key))}}</td></tr> @foreach($new_load as $load) <tr> <td>{{date("g:i a", strtotime($load->pick_up_time))}}</td> <td>{{$load->customer}}</td> <td>{{$load->pickup_location}}</td> <td>{{$load->drop_off_location}}</td> <!-- <td>{{$load->distance}}</td>--> <!--<td><textarea>{{$load->description}}</textarea></td>--> <!--<td>{{$load->customer_reference}}</td>--> <td>{{$load->vehicle}}</td> <!-- <td>{{$load->trailer}}</td>--> <td>{{$load->driver}}</td> <td><textarea>{{$load->notes}}</textarea></td> <td> <a href="{{route('EditLoad',$load->id)}}" class="fa fa-2x fa-pencil-square-o" style="color:#FF6F00;"></i></a> <a href="{{route('EditLoad',$load->id)}}" class="fa fa-2x fa-truck" style="color:#5cac00;"></i></a> <a href="{{route('EditLoad',$load->id)}}" class="fa fa-2x fa-phone" style="color:#00b1e6;"></i></a></td> </td> </tr> @endforeach @endforeach </tbody> -

最好的方法是首先对您的集合进行排序，以确保每个日期都有自己的负载：$loads = {....}; // here are the loads$dates = []; // here will be the dates// get all loads pickup dates$dates = $loads->pluck('pickup_date');// remove duplicated dates$dates = $dates->unique();// assign each load to its dateforeach($dates->toArray() as $key => $date) $dates[$date] = $loads->filter(function($load){ return $load->pickup_date === $date; });// return the dates instead of loadsreturn $dates;现在来说说刀片部分：<table> <tbody> @foreach($dates as $date => $collection) <tr> <td colspan="8" class="ml-1 h4 text-warning">{{date('l, d-F-Y', strtotime($date))}}</td> </tr> @foreach($collection as $load) <tr> <td>{{date("g:i a", strtotime($load->pick_up_time))}}</td> <td><textarea>{{$user->customer}}</textarea></td> <td>{{$load->pickup_location}}</td> <td>{{$load->drop_off_location}}</td> <!-- <td>{{$load->distance}}</td>--> <!--<td><textarea>{{$load->description}}</textarea></td>--> <!--<td>{{$load->customer_reference}}</td>--> <td>{{$load->vehicle}}</td> <td>{{$load->driver}}</td> <td><textarea>{{$load->notes}}</textarea></td> <td> <a href="{{route('EditLoad',$load->id)}}" class="fa fa-2x fa-pencil-square-o" style="color:#FF6F00;"></i></a> <a href="{{route('EditLoad',$load->id)}}" class="fa fa-2x fa-truck" style="color:#5cac00;"></i></a> <a href="{{route('EditLoad',$load->id)}}" class="fa fa-2x fa-phone" style="color:#00b1e6;"></i></a></td> </td> </tr> @endforeach @endforeach </tbody></table> -

我建议将日期保存在循环内，然后在渲染标题之前检查它是否与上一个相同；我不熟悉 Laravel，正在寻找一种方法来做到这一点，但看起来显然不鼓励在模板本身中设置局部变量。您需要做的基本上是按日期（或者在本例中，按标题）对结果进行分组，这样当您遍历循环时，您可以在同一日期拥有多行。这是一个非常粗略的示例，但应该可以让您更好地了解我的建议：$loads = array( array( 'pickup_date' => 'foo', /* more items here... */ ), array( 'pickup_date' => 'foo', /* more items here... */ ), array( 'pickup_date' => 'bar', /* more items here... */ ), array( 'pickup_date' => 'bar', /* more items here... */ ), array( 'pickup_date' => 'baz', /* more items here... */ ),);// Group by date...$grouped_loads = array_reduce($loads, function($carry, $load) { $carry[ $load['pickup_date'] ][]= $load; return $carry;}, array());此时，$grouped_loads应该如下所示：array( 'foo' => array( array( 'pickup_date' => 'foo', /* more items here... */ ), array( 'pickup_date' => 'foo', /* more items here... */ ), ), 'bar' => array( array( 'pickup_date' => 'bar', /* more items here... */ ), array( 'pickup_date' => 'bar', /* more items here... */ ), ), 'baz' => array( array( 'pickup_date' => 'baz', /* more items here... */ ), ),);因此，您现在将执行一个嵌套操作foreach，每个日期一个，然后日期中的每个项目一个。Laravel 为您提供了 和$loop，$loop->first因此您现在只能渲染第一项的标题：@foreach($grouped_loads as $loads) @foreach($loads as $load) @if ($loop->first) <tr> <td colspan="8" class="ml-1 h4 text-warning"> {{date('l, d-F-Y', strtotime($load->pickup_date))}} </td> </tr> @endif <tr> <td>{{date("g:i a", strtotime($load->pick_up_time))}}</td> <td><textarea>{{$user->customer}}</textarea></td> <td>{{$load->pickup_location}}</td> <td>{{$load->drop_off_location}}</td> <!-- <td>{{$load->distance}}</td>--> <!--<td><textarea>{{$load->description}}</textarea></td>--> <!--<td>{{$load->customer_reference}}</td>--> <td>{{$load->vehicle}}</td> <td>{{$load->driver}}</td> <td><textarea>{{$load->notes}}</textarea></td> <td> <a href="{{route('EditLoad',$load->id)}}" class="fa fa-2x fa-pencil-square-o" style="color:#FF6F00;"></i></a> <a href="{{route('EditLoad',$load->id)}}" class="fa fa-2x fa-truck" style="color:#5cac00;"></i></a> <a href="{{route('EditLoad',$load->id)}}" class="fa fa-2x fa-phone" style="color:#00b1e6;"></i></a> </td> </tr> @endforeach@endforeach
