    try {
        $this->validate($request, Venue::rules()); // Validation  Rules 
        $venue = Venue::saveOrUpdate($request);
        if($venue !== false) {
            if($request->get('continue', false)) {
                return redirect()->route('admin.venue.edit', ['id' => $venue->id])->with('success', trans('admin.venue.save_success'));
            } else {
                return redirect()->route('admin.venue.index')->with('success', trans('admin.venue.save_success'));
            }
        } else {
            return back()->with('error', "Unable to save venue")->withInput();
        }

    } catch (\Exception $ex) {
        return back()->with('error', "Unable to save venue")->withInput();
    }
}

public static function rules($id = '') {
    return [
        'name' => 'required|string|max:255',

        'status' => 'required|string|in:' . implode(",", Venue::STATUSES),

You may customize the error messagesused by the form requestby overriding the messages()method. Add custom messageson your Venueclass as follows-

您可以通过覆盖该方法来自定义 所error messages使用的。在您的班级上添加自定义如下-form requestmessages()messagesVenue

public static function messages($id = '') {
return [
    'name.required' => 'You must enter your name',
    'logo.required' => 'You must upload logo',
    'key.rules' => 'your messages'
];

And on your controller add messagesas third parameterlike-

在你的控制器上添加messages第三个像parameter-

$this->validate($request, Venue::rules(), Venue::messages());

This is the way I go about this and could serve as a guide. From your form, you've got basically 4 input fields and lets assume they are named name, client, logo and venue_type. The function in your controller that validates the form request can be like below:
N.B - you should put - use Validator; use Illuminate\Http\Request;- at the top of your class

这就是我处理此事的方式，可以作为指导。从您的表单中，您基本上有 4 个输入字段，假设它们被命名为name、client、logo 和venue_type。控制器中验证表单请求的函数如下所示：
注意 - 你应该放置 - 使用 Validator; 使用 Illuminate\Http\Request; - 在你的班级中名列前茅

public function validateFormRequest($request){
    try
    {

        //specify your custom message here
        $messages = [
          'required' => 'The :attribute field is required',
          'string'    => 'The :attribute must be text format',
          'file'    => 'The :attribute must be a file',
          'mimes' => 'Supported file format for :attribute are :mimes',
          'max'      => 'The :attribute must have a maximum length of :max',
        ];


        $validator = Validator::make($request->all(), [
              'name' => 'required|string|max:75',
              'client' => 'required|string|max:75',
              'logo' => 'required|file|mimes:jpeg,png,jpg,gif',
              'venue_type' => 'required|string',
          ], $messages);

        if($validator->fails()){ 
            // Validation Failed..log errors or Return Errors to view/blade
        } else{ 
            // Validation passed..Return true or positive info. i.e request can be saved
        }

    }catch (Exception $ex){
        //Log your errors or return some error message to your view/blade
    }
}

You can custom the validation message by ,

您可以通过以下方式自定义验证消息，

Go to the resources->lang->en->validation.php

前往 resources->lang->en->validation.php

and here you see,

你看，

'custom' => [
        'attribute-name' => [
            'rule-name' => 'custom-message',
        ],
    ],

Edit those as per your need.

根据您的需要编辑这些。

you can add custom errors like this.

您可以添加这样的自定义错误。

$validation->errors()->add('error_input', 'error text');

return redirect()->back()->withInput()->withErrors($validation);
