Laravel Custom Message - laravel

Question

Hi I am working with custom validation with laravel I am new in this right now my controller code is mention this is how I am validating the upload file.
Everything is working but I have issue displaying custom message on view page
it shows the default message not my custom message Please have a look and let me know if I am doing something wrong.
$this->validate(
$request, [
'project_file.*' => 'required|size:2048',
],
[
'project_file.required' => 'Upload File Field Is Required',
'project_file.max' => 'Upload File Field Must Be 2MB',
]
);
$messages = [
'required' => 'The File should not be more then 2Mb',
'size' => 'The must be exactly Mb.',
];
$validator = Validator::make($input, $rules, $messages);
if($validator->fails()) {
return Redirect::back()->withErrors($validator);
}
My View code to display error is:
#if ($errors->any())
<div class="alert alert-danger">
<strong>{!! implode('', $errors->all('<div>:message</div>')) !!}</strong>
</div>
#endif

Answer 1

I feel the issue might be because you have not passed the field name placeholder in the messages array.
You can add custom error messages for your validations. You can pass a third parameter Validator::make method.
$messages = [ 'required' => 'The :field should not be more then 2Mb' ];
$validator = Validator::make($input, $rules, $messages);
The :field place-holder will be replaced by the field name
Adding custom error messages only for a specific field using dot operation
$messages = [
'file.required' => 'The image should not be more then 2Mb',
];
Hope this helps.

It's better approach not to write validation logic in the controller because it results fat controller and quite messy controller so you can use separate request class to do in better way.
At first, use following command in console to create custom validation request class like this,
php artisan make:request PostRequest
Now, a file named PostRequest.php will be created at the app/Http/Requests/ in that file you should make validation like following.
<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class PostRequest extends FormRequest
{
/**
* Determine if the user is authorized to make this request.
*
* #return bool
*/
public function authorize()
{
return true;
}
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules()
{
return [
//
'project_file.*' => 'required|max:2048',
];
}
public function messages()
{
return [
'required' => 'Upload File Field Is Required',
'max' => 'The File should not be more then 2Mb',
];
}
}
Now, function in which form request is passed you have to change Request to PostRequest like this so that validation is performed automatically.
public function post(PostRequest $request){
//
}
