如何在 Laravel 5.4.12 中发布引导标签输入值？

Question

我正在研究 Laravel 项目，但有点困惑如何将标记多个值发布到控制器以及如何将其单独保存在 DB 中？这些值将针对单个外键保存在多行（记录）中..

<div class="form-group wish-tags">
 <label class="col-lg-3 control-label">Wish to visit:</label>
    <div class="col-lg-8">
      <input type="text" value="" data-role="tagsinput" id="tags" name="wish-tags" class="form-control">
     </div>
</div>
<div class="form-group wish-tags">
  <label class="col-lg-3 control-label">Already visited:</label>
      <div class="col-lg-8">
        <input type="text" value="" data-role="tagsinput" id="tags" name="visited-tags" class="form-control">
       </div>
</div>

访问列表

CREATE TABLE `visitedlist` (
`id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
`user_id` INT(10) UNSIGNED NOT NULL,
`locations` VARCHAR(100) NOT NULL,
`created_at` TIMESTAMP NULL DEFAULT NULL,
`updated_at` TIMESTAMP NULL DEFAULT NULL,
PRIMARY KEY (`id`),
INDEX `FK1_vistedlist_list` (`user_id`),
CONSTRAINT `FK1_vistedlist_list` FOREIGN KEY (`user_id`) REFERENCES `users` (`id`) ON UPDATE CASCADE ON DELETE CASCADE)

愿望清单表

CREATE TABLE `wishlist` (
`id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
`user_id` INT(10) UNSIGNED NOT NULL,
`locations` VARCHAR(50) NOT NULL,
`created_at` TIMESTAMP NULL DEFAULT NULL,
`updated_at` TIMESTAMP NULL DEFAULT NULL,
PRIMARY KEY (`id`),
INDEX `FK1_wishList` (`user_id`),
CONSTRAINT `FK1_wishList` FOREIGN KEY (`user_id`) REFERENCES `users` (`id`) ON UPDATE CASCADE ON DELETE CASCADE)

根据数据的格式，当您在控制器方法中接收数据时，您需要将其拆分为单独的项目，循环并保存每个项目。

所以，让我们以“item1,item2,item3”的形式接收方法中的项目，您的代码可能如下所示：

$locations = Request::input('wish-tags');

foreach (explode(",", $locations) as $location)
{
   $tag = new Tag();
   $tag->location = $location;
   $tag->user()->associate($theUser);
   $tag->save();
}
