Question

当管理员在<select></select>中选择一个类别时我想获取其ID以将其插入问题表

表格问题：

Schema::create('questions', function (Blueprint $table) {
            $table->increments('id');
            $table->string('question_text');
            $table->string('type');
            $table->integer('points');
            $table->integer('temps_reponse');

            $table->integer('categories_id')->unsigned();
            $table->foreign('categories_id')->references('id')->on('categories');

            $table->timestamps();

        });

表格类别：

Schema::create('categories', function (Blueprint $table) {
            $table->increments('id');
            $table->string('categorie');
            $table->timestamps();
        });

问题模型

class Question extends Model
{

    public function categorie()
    {
        return $this->belongsTo(Categorie::class, 'categories_id');
    }
}

分类模型

class Categorie extends Model
{
    public function question()
    {
        return $this->hasMany(Question::class, 'question_id')->withTrashed();
    }
}

                                                </select>

为了将id而不是字符串发送回服务器，请在每个选项元素上提供value属性：<option value={{$categorie->id}}>{{ $categorie->categorie }}</option>
