我想有以下情况。用户选择两个日期时间段，用于在该时间段内从数据库中选择联系人。如何将变量传递到其他页面/视图？
然后在下一页上，我想要显示传递的联系人，并且还有一个文本区域字段，用户可以在其中输入消息。
问题是，当下一页加载$contacts变量为空时。那么如何将变量传递给两页？
下面是Select Time Period
<form method="POST" action="selectContacts">
{{ csrf_field() }}
<div class="row">
<div class="col-lg-3 col-sm-3 col-xs-6">
<div class="form-group{{ $errors->has('date') ? ' has-error' : '' }}">
<label for="Event Date">Start Date</label>
<input type ='hidden' name='email' value='{{$email}}'>
<input type ='hidden' name='ip' value='{{$ip}}'>
<input name="start" type="text" class="form-control" id='fromperiod' placeholder="Date" required
@if ($errors->has('date'))
<span class="help-block">
<strong>{{ $errors->first('date') }}</strong>
</span>
@endif
</div>
</div>
</div>
<div class="row">
<div class="col-lg-3 col-sm-3 col-xs-6">
<div class="form-group{{ $errors->has('date') ? ' has-error' : '' }}">
<label for="Event Date">End Date</label>
<input name="stop" type="text" class="form-control" id='toperiod' placeholder="Date" required
@if ($errors->has('date'))
<span class="help-block">
<strong>{{ $errors->first('date') }}</strong>
</span>
@endif
</div>
</div>
</div>
<div class="row">
<div class="col-lg-12 col-sm-12 col-xs-12">
<input type="submit" class="btn btn-primary pull-right" value="Select">
<a href="sendsms" class="btn btn-default pull-left">
<i class="fa fa-arrow-left" aria-hidden="true"></i> Back
</a>
</div>
</div>
</form>
然后处理该selectContacts路由控制器的代码。
public function SelectContacts(Request $request)
{
$Startdate=$request->start;
$Stopdate=$request->stop;
validator = Validator::make($request->all(), [
'start' => 'required|min:10',
'stop' => 'required|min:10'
]);
if ($validator->fails()) {
return redirect('/sendsms')
->withErrors($validator)
->withInput();
}
$sdate=date_create("$Startdate");
$start = date_format($sdate,"Y/m/d H:i:s");
$date=date_create("$Stopdate");
$stop = date_format($date,"Y/m/d H:i:s");
$contacts = DB::table('Payment')
->whereBetween('time_paid', [$start, $stop])
->paginate(5);
//next page
return view('BulkSMS.send', 'contacts'=>$contacts]);
}
然后最后处理该文本区域NAD触头的显示的视图：
<form class="form-horizontal" role="form" method="post" action="/fun/sendbulk">
{{ csrf_field() }}
<div class="form-group">
<label for="message" class="col-sm-1 control-label">Message</label>
<div class="col-sm-6">
<textarea class="form-control" rows="4" name="message" required="Please Type Your Message Here" placeholder="Message"></textarea>
</div>
<input type ='hidden' name='email' value='{{$email}}'>
<input type ='hidden' name='ip' value='{{$ip}}'>
</div>
<div class="form-group">
<div class="col-sm-6 col-sm-offset-1">
<input id="submit" name="submit" type="submit" value="Send" class="btn btn-primary pull-right">
<a href="sendsms" class="btn btn-default pull-left">
<i class="fa fa-arrow-left" aria-hidden="true"></i> Cancel
</a>
</div>
</div>
</form>
<div class="row">
<div class="col-sm-4 col-sm-offset-2">
<table class="table table-hover">
<thead>
<th>ID</th><th>Name</th> <th>Mobile Number</th> <th>Remove</th>
</thead>
<tbody>
@foreach($contacts as $contact)
<tr>
<td> {{$contact->id }} </td>
<td> {{$contact->name}}</td>
<td> {{$contact->msisdn}}</td>
<td>
<form action= '' method='post'>
{{csrf_field()}}
<input type="radio" name="remove" value="other">
<!-- <input type='submit' name='submit' value='submit'> -->
</form>
</td>
</tr>
@endforeach
</tbody>
</table>
<div class="pull-right">{{ $contacts->links() }}</div>
</div>
</div>
最后，处理该/fun/sendbulk路由控制器。
public function sendsms(Request $request){
$message=$request->message;
$validator = Validator::make($request->all(), [
'message' => 'required|max:160',]);
if ($validator->fails()) {
return redirect('/selectContacts')
->withErrors($validator)
->withInput();}
$mob_numbers = implode(", " , $contacts);
$serviceArguments = array(
"mobilenumber" => $mobileNum,
"message" => $message
);
$client = new SoapClient("http://#smsws?wsdl");
$result = $client->process($serviceArguments)
}
