Question

我想将两个数据搜索结果合并到一个数组中，我使用array_merge，但有一个array_merge()错误：

参数1不是数组

如何将$vendor的雄辩结果转换为数组并将其与$plucked结合？

$vendor = Vendor::find($id);
$vendor_detail = VendorDetail::where('vendor_id',$id)->get();
$plucked = $vendor_detail->pluck('vendor_profile_value','vendor_profile_name');

$coba = array_merge($vendor,$plucked);

$plucked已经是数组我认为这里的问题是$vendor还不是数组

Answer 1

您可以这样做：

$vendor = Vendor::find($id);
$vendor_details = VendorDetail
             ::select('vendor_profile_value', 'vendor_profile_name')
             ->where('vendor_id', $id)
             ->get()
             ->toArray();

$coba = array_merge($vendor,$vendor_details);

get()方法执行查询，返回一个Collection实例，您可以在其中调用toArray()方法。

据我所知，您可以使用relationships和eager loading。

如果您的Vendor模型中有这样定义的one-to-many relationship：

public function details()
{
    return $this->hasMany(VendorDetails::class);
}

然后，您可以eager load这样的关系：

$vendor = Vendor::with('details')->find($id);
//                ^^^^^^^^^^^^^^

您甚至可以只加载所需的字段：

$vendor = Vendor::with('details:vendor_profile_value,vendor_profile_name')
                ->find($id);

然后，您的对象将具有一个名为“详细信息”的新属性，其中包含相关对象（或有限的选定字段的集合）。

您可以将$ vendor转换为如下所示的数组。
