是否有一种基于模型存储数组的方法？

Question

我正在尝试存储所有新的“ Aulas”，但它只能在数据库上保存第一个值，无法设法使其正常工作。新字段的增量为增量，因为第一个开始时为0。

<div id="newAula">

                    <div class="inline-flex" id="containerAula0">
                        <div class="inline-block w-full mr-2">
                        <label class="text-sm font-bold text-center uppercase opacity-70">Título</label>
                        <input type="text" name="titulo_aula0" class="w-full p-3 mt-2 mb-4 rounded bg-slate-200" required="">
                        </div>
                        <div class="inline-block ml-2">
                        <label class="text-sm font-bold uppercase opacity-70">Video ID</label>
                        <input type="text" name="video_id0" class="w-full p-3 mt-2 mb-4 rounded bg-slate-200" required="">
                        </div>
                        <div class="inline-block mt-10 ml-2">
                        <button id="removeAula0" class="h-8 px-3 font-bold duration-300 ease-in-out rounded cursor-pointer text-newwhite bg-red" type="button">
                        X
                        </button>
                        </div>
                        <p class="my-3">
                        </p>
                    </div>
                    <div class="inline-flex" id="containerAula1"> <div class="inline-block w-full mr-2"> <label class="text-sm font-bold text-center uppercase opacity-70">Título</label> <input type="text" id="titulo_aula1" class="w-full p-3 mt-2 mb-4 rounded bg-slate-200" required=""> </div> <div class="inline-block ml-2"> <label class="text-sm font-bold uppercase opacity-70">Video ID</label> <input type="text" id="video_id1" class="w-full p-3 mt-2 mb-4 rounded bg-slate-200" required=""> </div> <div class="inline-block mt-10 ml-2"> <button id="removeAula1" class="h-8 px-3 font-bold duration-300 ease-in-out rounded cursor-pointer text-newwhite bg-red"> X </button> </div> <p class="my-3"></p></div><div class="inline-flex" id="containerAula2"> <div class="inline-block w-full mr-2"> <label class="text-sm font-bold text-center uppercase opacity-70">Título</label> <input type="text" id="titulo_aula2" class="w-full p-3 mt-2 mb-4 rounded bg-slate-200" required=""> </div> <div class="inline-block ml-2"> <label class="text-sm font-bold uppercase opacity-70">Video ID</label> <input type="text" id="video_id2" class="w-full p-3 mt-2 mb-4 rounded bg-slate-200" required=""> </div> <div class="inline-block mt-10 ml-2"> <button id="removeAula2" class="h-8 px-3 font-bold duration-300 ease-in-out rounded cursor-pointer text-newwhite bg-red"> X </button> </div> <p class="my-3"></p></div></div>

控制器：

        $modulo = Modulo::create([
            'nome' => $request->nome,
            'sinopse' => $request->sinopse,
            'tumbnail' => $request->thumbnail
        ]);

        $aula = Aula::create([
            'titulo' => $request->titulo,
            'video_id' => $request->video_id,
            'modulo_id' => $modulo->id,
        ]);

         if (request()->hasFile('thumbnail')) {
             $thumbnail = request()->file('thumbnail')->getClientOriginalName();
             request()->file('thumbnail')->storeAs('public/modulos/', $modulo->id . '/' . $thumbnail, '');
             $modulo->update(['thumbnail' => $thumbnail]);
         }
         dd($modulo, $aula);

当我DD时，它炫耀： 对不起，任何新秀错误

在此部分：

<div class="inline-block w-full mr-2">
    <label class="text-sm font-bold text-center uppercase opacity-70">Título</label>
    <input type="text" name="titulo_aula0" class="w-full p-3 mt-2 mb-4 rounded bg-slate-200" required="">
</div>
<div class="inline-block ml-2">
    <label class="text-sm font-bold uppercase opacity-70">Video ID</label>
    <input type="text" name="video_id0" class="w-full p-3 mt-2 mb-4 rounded bg-slate-200" required="">
</div>
<div class="inline-block mt-10 ml-2">
    <button id="removeAula0" class="h-8 px-3 font-bold duration-300 ease-in-out rounded cursor-pointer text-newwhite bg-red" type="button">
         X
    </button>
</div>

您可以将输入称为这样的数组而不是索引：

<input type="text" name="titulo_aula[]">
<input type="text" name="video_id[]">

那么您可以在这样的laravel中获得一个数组，并为每个数组项目创建一个对象：

for($i=0; $i<count($request->input('titulo_aula')); $i++)
    {
        $aula = Aula::create([
            'titulo' => $request->input('titulo_aula')[$i],
            'video_id' => $request->input('video_id')[$i],
            'modulo_id' => $modulo->id
        ]);
    }
