我们如何在 laravel 5.3 中对多维数组进行自定义验证

Question

我在 Laravel 5.3 中使用二维字段数组。我希望根据需要验证所有值并显示各个错误消息。我在控制器函数中使用验证如下

$this->validate($request, [
            'training_id' =>'required',            
            'survey_name' =>'required',  
            'question.*' =>'required',
            'answer_option.*.*' =>'required'
        ],
        ['question.*.required' => 'The question field is required.',
        'answer_option.*.*.required' => 'The answer field is required.']);

在视图页面中，当我尝试显示所有错误消息时，只有第一行的答案会被验证，而其他的不会。错误信息如

Array ( [0] => The question field is required. [1] => The question field is required. [2] => The answer_option.0.0 field is required. [3] => The answer_option.0.1 field is required. [4] => The answer_option.0.2 field is required. [5] => The answer_option.0.3 field is required. [6] => The training id field is required. [7] => The survey name field is required. )

Answer 1

要单独验证带有自定义错误消息的所有字段，手动创建验证器是最佳解决方案....

第 1 步：

use Validator; (after namespace of any controller where validation is needed)

第 2 步：

添加一个方法（假设方法名check_data()）。并在下面的代码中放置....

public function check_data(Request $request){

    //Rules for form fields
    $rules = array(
        'training_id' =>'required',
        'survey_name' =>'required',
        'question' =>'required',
        'answer_option' =>'required'
    );

    //Custom message for individual fields
    $messages = array(
        'training_id.required' => 'Training Id should not be empty...',
        'survey_name.required' => 'Survey Name  is Essential...',
        'question.required' => 'Question is urgent...',
        'answer_option.required' => 'Answer option can be any one but required...'

    );

    $validator = Validator::make($request->all(), $rules, $messages);

    //Check for validation
    if ($validator->fails()) {
        //if validation fails
        return redirect()->back()->withInput()->withErrors($validator);
    } else {
        //Validation is successful and do as you wish
        return "All data are validated !!";

    }




}

希望它能奏效
