我在Laravel应用程序中收到以下错误。知道我做错了什么以及如何解决它？
类型错误：传递给Illuminate \ Database \ Grammar :: parameterize（）的参数1必须是类型数组，给定整数，在C：\ xampp \ htdocs \ wanderfoo \ vendor \ laravel \ framework \ src \ Illuminate中调用第681行\ Database \ Query \ Grammars \ Grammar.php
public function createEvent(Request $request){
$userid=Auth::user()->id;
$arr=collect($request->input('sch-title'));
$data = User::findOrFail(Auth::user()->id);
if (!empty($data)) {
//$arr=$request->input('sch-title');
//dd($arr);
$days=$request->input('days');
$this->validate($request , [
'title' => 'required',
'description' => 'required',
'firstDate' => 'required',
'secondDate' => 'required',
'days' => 'required',
'location' => 'required',
'event-img' => 'image|mimes:jpeg,png,jpg,gif',
'sch-title' =>'required',
'sch-desc' =>'required',
'sch-e' =>'required',
'sch-s' =>'required',
]);
if ($request->hasFile('event-img')) {
$image = $request->file('event-img');
$extension = $image->getClientOriginalExtension();
$filename = md5(str_shuffle(time())) . md5(time()) . '.' . $extension;
$path = public_path('images/event');
$image->move($path, $filename);
$request->request->add([
'event_img' => $filename,
]);
}
$request->request->add(['user_id'=>$userid]);
$eventData = Event::create($request->except(['_token', 'submit', 'tags','sch-e','sch-s','sch-title','sch-desc','event-img']));
$eventId=$eventData->id;
//dd($asd);
if(isset($eventId)){
for($i=0; $i<$days;$i++){
$request->request->add(['user_id'=>$userid]);
$request->request->add(['event_id'=>$eventId]);
$dayPostData = Day::create($request->except(['_token', 'submit', 'title','description','firstDate','secondDate', 'days','location','tags','event-img','event_img','sch-e','sch-s','sch-title','sch-desc']));
$dayId=$dayPostData->id;
//dd($dayId);
$countSchedules=count($arr[$i]);
for ($j=0; $j < $countSchedules; $j++){
$request->request->add(['user_id'=>$userid]);
$request->request->add(['event_id'=>$eventId]);
$request->request->add(['day_id'=>$dayId]);
$scheduleData = DaySchedule::create($request->except(['_token', 'submit', 'title','description','firstDate','secondDate' ,'days','location','tags','event-img','event_img']));
}
}
}
return back()->with('msg', ' Event Create Successfully..!');
}
}
路线：
Route::post('create_event','PostController@createEvent');
包含以下部分时出错：
$countSchedules=count($arr[$i]);
for ($j=0; $j < $countSchedules; $j++){
$request->request->add(['user_id'=>$userid]);
$request->request->add(['event_id'=>$eventId]);
$request->request->add(['day_id'=>$dayId]);
$scheduleData = DaySchedule::create($request->except(['_token', 'submit', 'title','description','firstDate','secondDate' ,'days','location','tags','event-img','event_img']));
}
