Validate Allowed Email Domains in Laravel

Published on by

Validate Allowed Email Domains in Laravel image

The Email Domain Rule package for Laravel can define a subset of allowed email domains you can use within a validator. The email domains are stored in the database, and the accompanying validation rule uses the database to verify an email field:

use HFarm\EmailDomainRule\EmailDomainRule;
use Illuminate\Support\Facades\Validator;
 
$email = 'my-email@example.com';
 
Validator::make([
'email' => $email,
], [
'email' => [
'string',
'email',
new EmailDomainRule,
],
])->validated();

This package also has wildcard support, which can come in handy in a multi-tenant application where you’d like to constraint which domain(s) a user can register within a given tenant. The package readme illustrates model customizations you can use to make this package support validation for multiple tenants:

use HFarm\EmailDomainRule\EmailDomainRule as BaseEmailDomain;
use Illuminate\Database\Eloquent\Builder;
 
class EmailDomain extends BaseEmailDomain
{
protected $fillable = [
'domain',
'tenant_id',
];
 
protected static function booted()
{
static::addGlobalScope('tenantAware', function (Builder $builder) {
$builder->where('tenant_id', auth()->user()->tenant_id);
});
}
}
