Ifill form but not show data in database

I try all the way but not show user_id and image_id in the table

This is model view of post

 protected $fillable = ['title','category','description','name','phone','city'];

public function image()
{
    return $this->hasMany('App\Image');
}

public function user(){
    return $this->belongsTo('App\User');
}
