php - 如何编码数据数组并保存到数据透视表 laravel

Question

我在这里想要的只是能够将所有服务 ID 保存到与给定关键字/标签关联的数据透视表中，但目前它所做的只是获取创建对象的最后一个 ID 并保存到数据透视表中用不同的关键词。假设我输入 [id1 => service1, id2 => service2] 和 [id1 = > keyword1, id2 => keyword2, id3 => keyword3] 而不是只保存 service2 的 id2 和我想要的所有关键字保存所有服务的所有 ID 和关键字。我希望这是有道理的

foreach($params['service'] as $key => $value){
      $service = Service::firstOrNew(['service' => $value, 'price' => $params['price'][$key], 'business_id' => $params['business_id']]);
      $service->service = $value;
      $service->price = $params['price'][$key]; 
      $service->business_id = $params['business_id'];
      $service->save();
    }

    foreach($params['keywords'] as $keyword){
      $cleaned_keyword = self::cleanKeywords($keyword); 
      $newKeyword = Keyword::firstOrNew(['keyword' => $cleaned_keyword]);
      $newKeyword->keyword = $cleaned_keyword;
      $newKeyword->save();
      $service->keywords()->syncWithoutDetaching([$newKeyword->id => ['business_id' => $params['business_id']]]);
  }

这是我所期望的，但它很棘手，因为例如一个或两个服务可以有多个关键字。注意：我在数据库中手动更改了这些值

这些是 dd($params) 的结果

基于 dd($params).attached 是结果，只有

"service" => array:2[
1 => "Mobile development"
]

已保存在数据透视表中并分配了所有关键字

如果这是一个好方法，请纠正我，我设法通过内部循环解决了这个问题。

    foreach($params['service'] as $key => $value) {
    $service = Service::firstOrNew(['service' => $value, 'price' => $params['price'][$key], 'business_id' => $params['business_id']]);
    $service->service = $value;
    $service->price = $params['price'][$key];
    $service->business_id = $params['business_id'];
    $service->save();
    foreach($params['keywords'] as $keyword) {
        $cleaned_keyword = self::cleanKeywords($keyword);
        $newKeyword = Keyword::firstOrNew(['keyword' => $cleaned_keyword]);
        $newKeyword->keyword = $cleaned_keyword;
        $newKeyword->save();
        $service->keywords()->syncWithoutDetaching([$newKeyword->id => ['business_id' => $params['business_id']]]);
    }
}
