让我首先展示我的代码。这是我的控制器功能代码

public function save(Request $request) {
    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();
    }
}

这是我的模型功能代码

public static function rules($id = '') {
    return [
        'name' => 'required|string|max:255',
        'logo' => 'required',
        'status' => 'required|string|in:' . implode(",", Venue::STATUSES),
        'venue_type_id' => 'required|string|not_in:0',
         'client_id' => 'required|string|not_in:0',
    ];
}

所以现在我提交表单验证时显示消息。我想改变这个消息。我怎么能这样做。

让我用验证信息显示我的表格: enter image description here

您可以通过覆盖error messages方法来自定义form request使用的messages()。在messages课程中添加自定义Venue,如下所示 -

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

在您的控制器上添加messages作为第三个parameter,如< - p>

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

这是我解决这个问题的方式,可以作为指导。从您的表单中,您基本上有4个输入字段,并假设它们被命名为 name,client,logo和venue_type 。控制器中验证表单请求的功能如下所示:
N.B-你应该把 - 使用验证器; 使用Illuminate \ Http \ Request; - 在班级的顶层

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
    }
}

您可以添加此类自定义错误。

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

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

return redirect()->back()->withInput()->withErrors(['error_input'=> 'error text');

您可以按

自定义验证消息

转到resources->lang->en->validation.php

在这里你看,

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

根据您的需要编辑这些内容。
