PHP
Our sales events platform Auctibles, collects phone numbers for several purposes:
Phone validation in Laravel is a crucial step for our sales events platform. It plays a significant role in ensuring smooth delivery coordination and reducing the risk of fraud.
We use validation rules, a practical feature of the PHP Laravel framework, to ensure reliable validation. This is where the Abstract comes in, enhancing the functionality of our platform.
We define a validation rule, AbstractPhoneValidation
that receives two parameters:
The rule uses our Abstract API key from the configuration file.
namespace App\Rules;
use Closure;
use Illuminate\Contracts\Validation\ValidationRule;
use Illuminate\Support\Str;
class AbstractPhoneValidation implements ValidationRule
{
/**
* Create a new rule instance.
*
* @return void
*/
public function __construct(
private string $phone_type,
private string $country,
) {}
/**
* Run the validation rule.
*
* @param \Closure(string): \Illuminate\Translation\PotentiallyTranslatedString $fail
*/
public function validate(string $attribute, mixed $value, Closure $fail): void
{
// Initialize cURL.
$ch = curl_init();
// Set the URL that you want to GET by using the CURLOPT_URL option.
curl_setopt(
$ch,
CURLOPT_URL,
'https://phonevalidation.abstractapi.com/v1/?api_key=' . config('app.ABSTRACT_PHONE_VERIFICATION_KEY') . "&phone=$value"
);
// Set CURLOPT_RETURNTRANSFER so that the content is returned as a variable.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Set CURLOPT_FOLLOWLOCATION to true to follow redirects.
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
// Execute the request.
$data = curl_exec($ch);
// Close the cURL handle.
curl_close($ch);
//The response from Abstract is a JSON
$data = json_decode($data);
// here, we do the validation
if (!$data->valid ||
// Is the phone number valid?
($this->phone_type && Str::lower($data->type) != $this->phone_type) ||
// If the phone type was given, what the phone number of the required type?
($data->country->code != $this->country)
// Does the country of the phone correspond to the expected country?
)
{
$fail('validation.' . $attribute)->translate();
}
}
}
As Abstract returns the phone type capitalized, we use Str::lower
to convert it to lowercase to correspond to our labeling of phone types.
We use the rule in validation, where the user's country two letters ISO 3166-1 alpha-2 code is stored in $country
:
$rules_array = [
'mobile_phone' => [new AbstractPhoneValidation('mobile', $country)],
'landline_phone' => [new AbstractPhoneValidation('landline', $country)],
'contact_phone' => [new AbstractPhoneValidation('', $this->country)],
]);
For a contact_phone
, any type of phone number is acceptable.
