文本区域验证最大规则在 laravel 6 中不起作用

Question

我尝试在textarea 中使用设置为 2000 的 max 规则，但我输入了超过 2000 个字符，验证不适用于其他输入字段，并且 使用空输入值重新加载页面强>即使我尝试少于 2000 个字符的数量，问题仍然存在，当我用空 textarea 添加所需的验证工作时，我也尝试将最大值更改为大小，但仍然存在同样的问题。

我想在下一个请求中使用旧输入值验证 textarea，如果字符数超过 2000 则显示错误消息。 我可以在 html 中使用 javascript 或 maxlength 属性，但想从服务器端执行。

textarea 有 974 个字符时所有输入验证失败

控制器中使用的方法

public function store(Request $request, User $user)
{
    $rules = [
        'Account_Number' => ['required', 'numeric'],
        'Account_Name' => ['required', 'string'],
        'email' => ['required', 'email', 'max:20'],
        'Date' => ['required', 'date_format:Y-m-d'],
        'problem_descrip' => ['required', 'min:1', 'max:2000'], // max not work 
        'comment' => ['nullable', 'string', 'required_if:Sovled,1', 'min:0', 'max:2000'], // something
        'Sovled' => ['nullable', 'numeric', new Checkbox($request->get('comment'), $request->get('Sovled'))]
    ];

    $customMessages = [
        'comment.required_if' => 'The :attribute field can not be blank when solved box is checked you need to write the solution.'
    ];

    $result = Validator::make($request->all(), $rules, $customMessages);

    if ($result->fails()) {
        return redirect()->back()->withErrors($result)->withInput($request->input());
    }

    dd($request->all());

    //$request->user->id
}

问题

Answer 1

看起来像是会话问题，尝试将会话驱动程序从 cookie 更改为 .env 中的文件

SESSION_DRIVER=file

Answer 2

试试这个，你必须添加别名 STRING，因为最大检测到文件大小。祝你好运，如果对您的问题有帮助，请按 UP 按钮:)。

$rules = [
    'Account_Number' => ['required', 'numeric'],
    'Account_Name' => ['required', 'string'],
    'email' => ['required', 'email', 'max:20'],
    'Date' => ['required', 'date_format:Y-m-d'],
    'problem_descrip' => ['required', 'string', 'min:1', 'max:2000'], //Add string here
    'comment' => ['nullable', 'string', 'required_if:Sovled,1', 'min:0', 'max:2000'], // something
    'Sovled' => ['nullable', 'numeric', new Checkbox($request->get('comment'), $request->get('Sovled'))]
];
