Php 如何防止删除和更新？

我有一个这样的多步骤的形式

我在

educationals

表格中添加了这个表格

当我点击+按钮时，我添加了其他信息

它成功地添加到数据库中。现在，当添加其他数据时

1

的id已删除。。。其中是

1

的id

我的刀片

<form method="post" enctype="multipart/form-data" action="{{ route('update', auth()->id()) }}">
<select name="educationals['+countStudy+'][grade_id]">
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
</select>
<input type="text" name="educationals['+countStudy+'][field]">
<input type="text" name="educationals['+countStudy+'][branch]">
<select name="educationals['+countStudy+'][institution_id]">
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
</select>
<input type="text" name="educationals['+countStudy+'][institution_education]">
<input type="text" name="educationals['+countStudy+'][gpa]">
<select name="educationals['+countStudy+'][nation_id]">
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
</select>
<select name="educationals['+countStudy+'][province_id]">
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
</select>
<input type="text" name="educationals['+countStudy+'][province_name]">
<select name="educationals['+countStudy+'][town_id]">
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
</select>
<input type="text" name="educationals['+countStudy+'][town_name]">
<input type="text" name="educationals['+countStudy+'][entrance]">
<input type="text" name="educationals['+countStudy+'][graduate]">
<input type="checkbox" name="educationals['+countStudy+'][currently_studying]">
<button type="submit">Update</button>
</form>

我发疯了，我试了三天，但我还没有解决我的问题。

不确定我是否完全从中得到问题，但控件中的最后一行代码是执行

->delete（）

我们实际上没有收到你的问题。在执行删除之前，你可以执行

dd（$Educational->Pull（'id'）

？让我们看看id是否在这里？@MahmoudKhosravi我想id

1

不在您的

$educationals->pulk（'id'）

，因此它会按照代码

auth（）->user（）->educationals（）->whereNotIn（'id'，$educationals->pulk（'id'）->delete（）的预期被删除@RobBiermann-
$educationals = collect([]);

foreach ($request->educationals as $key => $educational) {
    $data = collect($educational);

    $model = Educational::updateOrCreate($data->only(['grade_id', 'institution_id'])->toArray() + [
            'user_id' => auth()->id()
        ], $data->except(['grade_id', 'institution_id', 'currently_studying'])->toArray() + [
            'currently_studying' => $request->has("educationals.{$key}.currently_studying") ? 1 : 0
        ]
    );
    $educationals->push($model);
}

auth()->user()->educationals()->whereNotIn('id', $educationals->pluck('id'))->delete();
