Laravel: custom multidimensional array validation

Question

I've a form which user will insert many records at a time. Each record will have an id, a start date and an end date. To process the input data, I'm looking for the best way to validate all these things.

I'll have to require at least one record
For each inputed record, id should exists at another table, date start and end date should be valid dates and end date should be older than start date

So I need some sort of multidimensional array validation here... Is there any custom validation plugin/code already coded for that?

I've tried to extend Laravel validation but I couldn't get even close to what I'd like...

What I've tried:

app/services/validators/LearningPathValidator.php (I'm using laravel-extended-validator)

<?php

use Crhayes\Validation\ContextualValidator;

class LearningPathValidator extends ContextualValidator
{
    protected $rules = [
        'default' => [
            'name'    => 'required|max:96',
            'courses' => 'required|multi_array:course_id=required;exists:courses,date_start=required;date_format:d/m/Y,date_end=required;date_format:d/m/Y'
        ],
    ];
}

app/validations.php (Here I'm extending Illuminate\Validation\Validator class)

<?php

class AppValidator extends Illuminate\Validation\Validator
{
    protected function validateMultiArray($attribute, $value, $parameters)
    {
        if (!is_array($value)) {
            return false;
        }

        foreach ($parameters as $parameter) {
            list($_attribute, $rules) = $this->parseRule(
                str_replace(['=', ';'], [':', ','], $parameter));

            foreach ($rules as $rule) {
                foreach (array_keys(Input::get($attribute)) as $idx){
                    $this->validate(sprintf('%s.%d.%s', $attribute, $idx,
                        snake_case($_attribute)), $rule);
                }
            }
        }

        return count($this->messages->all()) === 0;
    }
}

My start/global.php: (Here I extend Illuminate\Validation\Validator with AppValidator)

// ...

Validator::resolver(function($translator, $data, $rules, $messages) {
    return new AppValidator($translator, $data, $rules, $messages);
});

// ...

My models are using courses[$index][course_id], courses[$index][date_start] and courses[$index][date_end] as field names.

Actually I can't require at least one record as I said before and I can't assure end date will be older than start date. Any suggestions to rewrite what I've coded? Thank you in advance!

Hsve you considered using AJAX in order to have only one request at the time? — clod986

I created a package to do just this as I encountered the same problem with data from AngularJS.
