如何使用Laravel存储多个复选框

Question

我试图保存到我的数据库复选框我检查到我的视图。我有一个title，一个type_article(下拉框)，theme(复选框)和contents。

我在article_list.blade.view:

中这样做

@foreach ($themes as $theme)  
   <div class="form-check form-check-inline">
     <input class="form-check-input" type="checkbox" name="themeCheckbox[]" value="{{ $theme->theme_id }}">
     <label class="form-check-label">{{ $theme->nom_theme }}</label>
   </div>
@endforeach

My AdminController:

    public function createArticle(Request $request)
    {
       $data = $request->validate([ // $data = $this->validate($request
        'titreArticle' => 'bail|required|between:5,40',
        'typeArticle' => 'bail|required',
        'themeCheckbox' => 'required|array|min:1',
        'themeCheckbox.*' => 'required|string|distinct|exists:theme,nom_theme',
        'contenuArticle' => 'bail|required',
       ]);
       $type_articles = Type_article::findOrFail($data['typeArticle']);
       $article = new Article();
       $article->type_article()->associate($type_articles);
       $themes = Theme::whereIn('nom_theme', $data['themeCheckbox'])->get();
       $article->theme()->associate($themes);
       $article->titre = $data['titreArticle'];
       $article->contenu = $data['contenuArticle'];
       $article->date_creation = date('Y-m-d');
       $article->save();
       $article->theme()->attach($themes);
       return view('admin/panel_admin/panel_admin');
   }

一切都很好，除了复选框的问题。我确实在我的视图中显示了我的错误，这是当我提交3个复选框时出现的:

The selected themeCheckbox.0 is invalid.
The selected themeCheckbox.1 is invalid.
The selected themeCheckbox.2 is invalid.

我有一个数据透视表(Article和Theme为表，Article_theme为数据透视表)。

编辑:

问题是$themes = Theme::whereIn('nom_theme', $data['themeCheckbox'])->get();，我需要将nom_theme更改为id_theme。

Answer 1

您应该将$theme->theme_id传递给复选框的名称数组。然后，检查数组中是否存在id，因为复选框的默认行为是删除未选中的项。

<input class="form-check-input" type="checkbox" name="themeCheckbox[{{$theme->theme_id}}]" value="1">

我将复选框的值设置为1，这意味着当你选中它时，$theme->theme_id的键值将被赋值为1。该复选框的示例输出如下所示:

themeCheckbox=[
    '1' => '1';
    '2' => '1';
    '3' => '1';
    '4' => '1';
    '5' => '1';
];

因此，您必须在代码中查找键，而不是值，因为它们是唯一的(1)。如下所示修改控制器并在其中使用array_keys()方法:

$themes = Theme::whereIn('nom_theme', array_keys($data['themeCheckbox']))->get();

更新删除不必要的验证'themeCheckbox' => 'required|array|min:1',，并修复另一个，如下所示:

'themeCheckbox.*' => 'required',
