我试图使用模式提交表单，但收到了此错误。422（不可处理实体）。在我的菜单模型中，我使用受保护的$table='Menu'指定了我的表名$Menu

<script type="text/javascript">

$(document).ready(function(){

$.ajaxSetup({
headers: {
    'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});

我的方法

      public function post(Request $req)
     {
    if($req->ajax()){

    $req->validate([
        'Item_Code'=>'required',
        'Name'=>'required',

我的路线

 Route::post('/post', 'AdminController@post')->name('create.inventory');

422是Laravel验证的状态代码

检查输入数据，可能其中一个值为null

这就是我如何创建这样一个函数的方法

引导模型-我在表单中添加了一个ID，还添加了一个div，其中包含用于验证和成功消息的消息类

<div class="modal-body">
    <div class="messages"></div>
    <form id="productForm">
        {{ csrf_field() }}
        <label for="required-input" class="require">Item Code:</label>
        <input type = "text" class="form-control" placeholder="Item Code" id = "Item_Code">

        <label for="placeholder-input" class="require">Name:</label>
        <input type= "text" class="form-control" placeholder="Name" id = "Name">

        <label for="single-select" class="require">Printer</label>
                                    <select id="Printer" class="form-control">
                                        <option>Kitchen</option>
                                        <option>Bar</option>
                                    </select>


        <label for="single-select">Category</label>
                                    <select id="Category" class="form-control">
                                        <option>Japanese</option>

你能给我个建议吗example@FrancisLobosApeajax请求中的一些数据值为null，在控制器中使用

validate（）进行验证

用于检查所有需要的字段的函数检查我自己。

422是Laravel验证的状态代码

是我的

FormRequest

类型参数的一个键。我从一开始就走错了方向。投票结果是：你使用

id=…

作为输入，但你应该使用

name=

（代替或添加id）以在laravel中正确获取它们。422表示您的验证失败，这是因为您的请求为空。您还需要帮助吗？@Yosef是的，我仍然需要help@FrancisLobosApe查看我发布的解决方案：）
