Question

我尝试将（表公司）（公司ID - ＆gt;主键）设置为（表分支）（company_id）中的外键。

控制器：

public function savebranchinfo(Request $request){
        $validator = Validator::make($request->all(),[
            'name' => 'required|min:5',
            'email' =>'required|unique:branch',
            'address' =>'required',
            'contact' =>'required|min:11',
            'open_hours' =>'required',
        ]);
        if($validator->passes()){
            $branch = new Branch();
            $branch->company_id = $request->company_id;
            $branch->name = $request->name;
            $branch->email = $request->email;
            $branch->address = $request->address;
            $branch->contact = $request->contact;
            $branch->open_hours = $request->open_hours;
            if($branch->save()){
                $request->session()->flash('message','Successfully save!!');
                return redirect('/add/branch');
            }
        }else{
                return redirect('/add/branch')->withErrors($validator)->withInput();
        }
    }
}

迁移：

  public function up()
{
    Schema::create('branch', function (Blueprint $table) {
        $table->increments('id');
        $table->integer('company_id')->unsigned();
        $table->foreign('company_id')->references('id')->on('company');
        $table->String('name');
        $table->String('email');
        $table->String('address');
        $table->String('contact');
        $table->String('open_hours');
        $table->timestamps();
    });
}

查看：

<input type="hidden" value="company_id{{$company->id}}">

错误：

SQLSTATE [23000]：完整性约束违规：1048列＆＃39; company_id＆＃39;不能为空（SQL：插入branch company_id，name，email，address，contact，open_hours， updated_at，created_at）值（，Mahmood Son，mahmoodson @ gmail.com，bilal gunj，04237152734，上午8点至晚上8点，2017-02-25 12：06：35，2017-02-25 12 ：06：35））

Answer 1

在我看来，您忘记了表单中的输入名称：

<input type="hidden" name="company_id" value="{{$company->id}}">

违规完整性约束：1048栏＆＃39; company_id＆＃39; laravel5.3不能为null
