insert data through checkbox in laravel - laravel

Question

I am trying to insert the checkbox data in database in which data are coming dynamically from database,
Here is the form :
<form action="{{ $action }}" method="post" enctype="multipart/form-data">
#csrf()
#if(!empty($method)) #method($method) #endif
<table class="table table-striped table-bordered table-hover" id="dataTables-example">
#foreach($users as $k=>$u)
<tr>
<td><input type="checkbox" name="user_id[]" value="{{ $u->id }}"></td>
<td>{{ $u->name }}</td>
<td>{{ trim($evtitle) }}</td>
<td>{{ trim($evteacher) }}</td>
</tr>
#endforeach
</table>
<input type="text" name="question_id[]" value="{{ trim($evid) }}">
<input type="submit" class="btn btn-lg btn-success" value="Share" name="btn_btn_add_product">
</form>
Here is the controller :
$rs = ShareQuestion::create([
'user_id' => $request->input('user_id'),
'question_id' => $request->input('question_id')
]);
if($rs)
{
$message = array('flag'=>'alert-success', 'message'=>'Successfully');
return redirect()->route('auth.question.index')->with(['message'=>$message]);
}
$message = array('flag'=>'alert-danger', 'message'=>'Please try again');
return redirect()->route('auth.question.share')->with(['message'=>$message]);
Please help me out,

Answer 1

I think here is the issue as your checkbox is not checked so data is not passed to the controller function.
so change from(if you want to send all user_id)
<td><input type="checkbox" name="user_id[]" value="{{ $u->id }}"></td>
to
<td><input type="checkbox" name="user_id[]" checked value="{{ $u->id }}"></td>
or you can pass the condition for a checked attribute by
{{ Form::checkbox('user_id[]',$u->id,true, array('class'=>'some_class')) }}

$request->user_id and $request->question_id, array of values you have to use json_encode() method
$rs = ShareQuestion::create([
'user_id' => json_encode($request->user_id),
'question_id' => json_encode($request->question_id)
]);
