Laravel validator custom error returns a prompt message and displays it in the front end



By default, laravel validator returns prompt messages in English. In most cases, we need to customize error return prompt messages. This article will show you how to customize error messages and show them in the front end.

Custom error message

Don’t blame me for being too direct

$messages = [
   'phone. Unique' = > 'duplicate phone number',
   'required' = > 'please fill in the information completely',

$this->validate($request, [
   'phone' => 'required|unique:table_name',
   'name' => 'required',
  ], $messages);

Is it very simple? Just add an array of prompt information in the parameter of the validate () method. The key of the array is the field. The verification method or the direct verification method. Obviously, the latter is applied to all. The former is applied to a certain field.

Of course, you may not use this method. Other verifiers are the same. Here:

$validator = Validator::make($input, $rules, $messages);

Yes, this is also the third parameter. It’s the same way as above.

Error prompt front end display

Let’s talk about how the front end displays these error prompts. Let’s print them one by one

@if ($errors->any())
 @foreach ($errors->all() as $error)
 <div role="alert">
  < strong > errors encountered: < / strong >
   {{ $error }}
  <button type="button" data-dismiss="alert" aria-label="Close">
   <span aria-hidden="true">×</span>

Forgive me for the poor front-end, so I used the bootstrap style. In order to highlight the main part, the clothes of this code are as follows:

@if ($errors->any())
 @foreach ($errors->all() as $error)
   {{ $error }}

Well, it’s refreshing in a moment.
