Email validation with TLD

I think your best bet is making a custom validation rule.

php artisan make:rule EmailMustHaveTLD

EmailMustHaveTLD.php

<?php

namespace App\Rules;

use Illuminate\Contracts\Validation\Rule;

class EmailMustHaveTLD implements Rule
{
    /**
     * Create a new rule instance.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Determine if the validation rule passes.
     *
     * @param  string  $attribute
     * @param  mixed  $value
     * @return bool
     */
    public function passes($attribute, $value)
    {
        if (! strpos($value, '@')) {
            return;
        }

        $domain = explode('@', $value)[1];

        $hasTLD = !! strpos($domain, '.');

        return $hasTLD;
    }

    /**
     * Get the validation error message.
     *
     * @return string
     */
    public function message()
    {
        return 'E-mail must have a TLD';
    }
}

In your controller:

use App\Rules\EmailMustHaveTLD;

public function store(Request $request)
{
    $request->validate([
      // ...
      'email' => ['required', 'email', new EmailMustHaveTLD],
      //...
  ]);
}

Yeah this is what I had already done in addition to registering the Rule with Validator in a Service Provider...was hoping there'd be a nicer way out of the box

There is an easier way. This same question was asked recently. https://laracasts.com/discuss/channels/general-discussion/laravel-58-override-email-validation-use-57-rules

You can basically just tell laravel to use a different class when the email validation rule is used, so it uses your instead. no other code needs to change. Just need to do a swap in the IOC container.

That's more like it. Thanks chief.
