我设置了使用Laravel名册的Web应用程序，我需要一个表单，输入所有字段，然后将它们存储到数据库中，当我使用鼓捣一切工作正常，或者如果我提交单行，但是当我尝试提交整个形式只有最后一排被读取。
这是rota.blade.php文件
{!! Form::open(['action' => 'RotaController@store', 'method' => 'POST', 'enctype' => 'multipart/form-data']) !!}
<table class="table table-striped table-bordered">
<thead class="thead-dark">
<tr>
<th scope="row">Name</th>
<th scope="row">Sunday</th>
<th scope="row">Monday</th>
<th scope="row">Tuesday</th>
<th scope="row">Wednesday</th>
<th scope="row">Thursday</th>
<th scope="row">Friday</th>
<th scope="row">Saturday</th>
</tr>
</thead>
<tbody>
<!--
* create a loop to iterate through each instance in the weekly rota database
* and create a row for each one; in case the username coincides with the name in the rota
* add class="active" to each row, so it is easier for the user to identify its own row
-->
@csrf
@foreach ($users as $user)
<tr>
<th scope="row">
{{$user->first_name}}
<input name="user_id" type="hidden" value="{{$user->id}}">
<input name="week_no" type="hidden" value="{{$currWeek}}">
</th>
<th scope="row">
{{Form::text('sunday', '', ['class' => 'form-control'])}}
</th>
<th scope="row">
{{Form::text('monday', '', ['class' => 'form-control'])}}
</th>
<th scope="row">
{{Form::text('tuesday', '', ['class' => 'form-control'])}}
</th>
<th scope="row">
{{Form::text('wednesday', '', ['class' => 'form-control'])}}
</th>
<th scope="row">
{{Form::text('thursday', '', ['class' => 'form-control'])}}
</th>
<th scope="row">
{{Form::text('friday', '', ['class' => 'form-control'])}}
</th>
<th scope="row">
{{Form::text('saturday', '', ['class' => 'form-control'])}}
</th>
</tr>
@endforeach
{{Form::submit('Submit', ['class' => 'btn btn-primary'])}}
</tbody>
</table>
{!! Form::close() !!}
这是RotaController@store：
public function store(Request $request)
{
//validation
$this->validate($request,[
'user_id' => 'required',
'sunday' => 'required',
'monday'=> 'required',
'tuesday'=> 'required',
'wednesday'=> 'required',
'thursday'=> 'required',
'friday'=> 'required',
'saturday'=> 'required',
'week_no'=> 'required'
]);
//create a field
$rota = new Rota;
$rota->user_id = $request->input('user_id');
$rota->week_no = $request->input('week_no');
$rota->sunday = $request->input('sunday');
$rota->monday = $request->input('monday');
$rota->tuesday = $request->input('tuesday');
$rota->wednesday = $request->input('wednesday');
$rota->thursday = $request->input('thursday');
$rota->friday = $request->input('friday');
$rota->saturday = $request->input('saturday');
$rota->save();
$users = DB::table('users')->orderBy('first_name', 'asc')->get();
return view('admin.admin-rota')->with('users', $users);
}
我试图dd($request)，它实际上只获得了最后一组输入字段，我想我必须通过他们循环，但我不知道怎么办。有没有人有什么尝试任何建议？感谢很多的任何反馈，我还是很新的使用这个框架。
我会通过用户组表单数据。
@foreach ($users as $user)
<tr>
<th scope="row">
{{$user->first_name}}
<input name="users[{{$user->id}}][id]" type="hidden" value="{{$user->id}}">
<input name="users[{{$user->id}}][week_no]" type="hidden" value="{{$currWeek}}">
</th>
<th scope="row">
{{Form::text("users[$user->id][sunday]", '', ['class' => 'form-control'])}}
<th scope="row">
{{Form::text("users[$user->id][monday]", '', ['class' => 'form-control'])}}
</tr>
@endforeach
{{Form::submit('Submit', ['class' => 'btn btn-primary'])}}
</tbody>
在控制器，你将有与针对每个用户的数据数组。然后你的控制器可以是这样的：
public function store(Request $request)
{
//validation
$this->validate($request,[
'users.*.user_id' => 'required',
'users.*.sunday' => 'required',
...
]);
foreach($request->get('users') as $userData){
$rota = new Rota;
$rota->user_id = $userData['user_id'];
$rota->week_no = $userData['week_no'];
$rota->sunday = $userData['sunday'];
...
$rota->save();
}
//create a field
$users = DB::table('users')->orderBy('first_name', 'asc')->get();
return view('admin.admin-rota')->with('users', $users);
}
您可以附加一个索引到每一个输入的名字，并保持一个隐藏的输入来存储集合计数。
@php
$idx = 0;
@endphp
@foreach ($users as $user)
<tr>
<th scope="row">
{{$user->first_name}}
<input name="user_id_{{$idx}}" type="hidden" value="{{$user->id}}">
<input name="week_no_{{$idx}}" type="hidden" value="{{$currWeek}}">
</th>
<th scope="row">
{{Form::text('sunday_' . $idx , '', ['class' => 'form-control'])}}
</th>
<th scope="row">
{{Form::text('monday_' . $idx, '', ['class' => 'form-control'])}}
</th>
<th scope="row">
{{Form::text('tuesday_' . $idx, '', ['class' => 'form-control'])}}
</th>
<th scope="row">
{{Form::text('wednesday_' . $idx, '', ['class' => 'form-control'])}}
</th>
<th scope="row">
{{Form::text('thursday_' . $idx, '', ['class' => 'form-control'])}}
</th>
<th scope="row">
{{Form::text('friday_' . $idx, '', ['class' => 'form-control'])}}
</th>
<th scope="row">
{{Form::text('saturday_' . $idx, '', ['class' => 'form-control'])}}
</th>
@php
$idx++;
@endphp
</tr>
@endforeach
{{-- holds numbers of users count --}}
<input type="hidden" name="user_count" value="{{$users->count()}}">
在控制器中，遍历用户的使用可变$user_count的，我们从刀片文件得到了量。每个数据变量都会有附加的索引，然后你就可以对应您从叶片文件中输入正确的数据。请注意，这里的验证正在每次迭代的每个物体上进行。如果您想在保存之前验证所有数据，请与验证另一foreach保存数据之前。
for ($i=0; $i < $request->user_count; $i++) {
//validation
$this->validate($request,[
'user_id_' . $i => 'required',
'sunday_' . $i => 'required',
'monday_' . $i=> 'required',
'tuesday_' . $i => 'required',
'wednesday_' . $i=> 'required',
'thursday_' . $i => 'required',
'friday_' . $i=> 'required',
'saturday_' . $i=> 'required',
'week_no_' . $i=> 'required'
]);
//create a field
$rota = new Rota;
$rota->user_id_{$i} = $request->input('user_id_' . $i);
$rota->week_no_{$i} = $request->input('week_no_' . $i);
$rota->sunday_{$i} = $request->input('sunday_' . $i);
$rota->monday_{$i} = $request->input('monday_' . $i);
$rota->tuesday_{$i} = $request->input('tuesday_' . $i);
$rota->wednesday_{$i} = $request->input('wednesday_' . $i);
$rota->thursday_{$i} = $request->input('thursday_' . $i);
$rota->friday_{$i} = $request->input('friday_' . $i);
$rota->saturday_{$i} = $request->input('saturday_' . $i);
$rota->save();
}
