我试图在laravel框架中插入复选框值到数据库中，但是不能。我总是犯错误。
这是我得到的错误:尝试分配非对象的属性'record_id3'
这是我在Controller中的代码:
public function Postindex1(Request $request){
$pd4 = new Questioncourse();
$pd4 = $request->all();
$pd5 = implode(',', $request->input('hobby'));
$pd5 = implode(',', $request->input('interest'));
$pd5 = implode(',', $request->input('career'));
$pd4['hobby'] = $pd5;
$pd4['interest'] = $pd5;
$pd4['career'] = $pd5;
$pd4->record_id3 = Auth::user()->id;
$pd4->save();
return redirect('/question')->with('success', 'Your preferences have been saved!'); }
这是我在迁移中的代码:
Schema::create('questioncourses', function (Blueprint $table) {
$table->id();
$table->integer('record_id3')->unsigned();
$table->foreign('record_id3')->references('id')->on('users');
$table->string('hobby');
$table->string('interest');
$table->string('career');
$table->timestamps();
提前致谢
您的代码中存在一些错误:
$pd4 = new Questioncourse(); // Here you instanciate the Questioncourse Model
$pd4 = $request->all(); // Here you discard the value of $pd4 and change it with an Array
// containing the $request data
因此，您不再有 你要做的是: >
为每个复选框组使用不同的变量（不仅仅是 使用赋值器来设置模型属性的值，因此您的最终代码应该如下所示:public function Postindex1(Request $request){
$pd4 = new Questioncourse();
// $pd4 = $request->all(); There is no need for this
$hobby = implode(',', $request->input('hobby'));
$interest = implode(',', $request->input('interest'));
$career = implode(',', $request->input('career'));
$pd4->hobby = $hobby;
$pd4->interest = $interest;
$pd4->career = $career;
$pd4->record_id3 = Auth::user()->id;
$pd4->save();
return redirect('/question')->with('success', 'Your preferences have been saved!');
}
