Answer 1

Here is an Alternative $this->validate(request(), [rules], [custom messages], [Custom attribute name]);

            $this->validate(request(), [
                'fname' => "required|alpha_dash|max:20",
                'lname' => "required|alpha_dash|max:30",
                'extensionName' => "required|alpha_dash|max:20",
                'specialization' => "max:100",
                'subSpecialization' => "max:100"
            ], [], 
            [
                'fname' => 'First Name',
                'lname' => 'Last Name',
                'extensionName' => 'Extension Name',
                'specialization'=> 'Specialization',
                'subSpecialization'=> 'Sub Specialization'
            ]);

Answer 2

Here's an alternative:

$data = ['name' => e(Input::get('name')), 'cat' => e(Input::get('cat'))];
$rules = ['name' => 'required|min:3', 'cat' => 'required'];
// pass an item from lang array if you need to
$nice_input_names = ['cat' => trans('lang_file.a_name_for_the_category_input')];

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

Answer 3

You can specify custom error message for your field as follows.

$messages = array(
    'cat.required' => 'The category field is required.',
);

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

Please see Custom Error Messages section in laravel documentation for more information.

Or you can keep a mapping for your field names like below. And you can set those into you validator. So you can see descriptive name instead of real field name.

$attributeNames = array(
   'name' => 'Name',
   'cat' => 'Category',     
);

$validator = Validator::make ( Input::all (), $rules );
$validator->setAttributeNames($attributeNames);

Answer 4

I'm using this to deal with dynamic row addition in forms. This answer is provided in context of managing larger forms. This answer is for Laravel 5

Form request

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;
use Response;

class SomeThingFormRequest extends Request {

public function authorize()
{
 //be nice
}

public function rules()
{
//my loop building an array of rules ex: $rules['thing.attribute.'.$x]
}

public function attributes()
{
    return [
        'thing.attribute'.$x => 'Nice Name',
    ];
}

Hope this help steer you in the right direction if you are using Laravel 5. I'm currently working on testing it out. The documentation seems to be amiss regarding this potential?

I did some digging in the framework (Illuminate\Foundation\Http\FormRequest.php) and (Illuminate\Validation\Validator.php) for the clues.

Answer 5

you can customize every message ,also change the attribute fields name in validation.php (resources/lang/en/). for set the attribute in validation.php

'attributes' => [
   'name' => 'Name',
   'cat' => 'Category',
   'field_name'=>'your attribute'
],

Answer 6

Simply got to resources/lang/en/validation.php

There is a blank array named attributes.

add your attribute name here like 'cat'=>'category'

now all validation messages show category instead of cat.
