Custom laravel 5 validation rules

Hi everyone,

I'm looking to create a custom validation rules with larvel 5 to use within my FormRequest. Specifically a require_if_not rule.

to do something like :

public function rules () {
return [
"aField" => "require_if_not:someOtherField,hasSomeValue",
...

I've looked at a few options and none does the job how I want it to.

This thread comes close but it actually performs some more checks after the validation passes and I'd like to implement a rule rather than hardcoding checks afterwards. https://laracasts.com/discuss/channels/general-discussion/custom-validation-function-in-laravel-5

Of course larvel 4 validation extension would do the job exactly as I would like, but I can't seem to translate it for L5. (http://culttt.com/2014/01/20/extending-laravel-4-validator/)

Any thoughts ?

Thanks !

Thanks!!! I missed it.

Still I can't get any one working, extending from the FormRequest Constructor or creating a separate file that will be loaded through a service provider.. am I missing something or did it change since that commit..

Starting to pull my hair on this.

Pretty straight forward though ...


use Illuminate\Validation\Factory;

class AnswersFormRequest extends Request {

    public function __construct(Factory $factory)
    {
        $factory->extend('test', function ($attribute, $value, $parameters)
            {
                return false;
            },
            'Bad number format'
        );
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            "ville" => "test",

The validation passes !!

it works when using the extendImplicit method although I don't really understand the difference

  $factory->extendImplicit('test', function ($attribute, $value, $parameters)
            {
                // return logic test
            },
            'Bad number format'
        );

Implicits extensions are if you dont need value (that is in array with rule name) like "required", it's your case. So it cant work with "extend".

Ok. If I get it right extendImplicit will run even if no inputs are provided for the field when extend will only run if one is.

Thanks.
